Re: [U-Boot-Users] does u-boot support 4kec now?

i see that in u-boot /cpu directory, there are several directories for arm,like arm920t,arm720t,etc.but for mips i only find a mips directory. does it means that the start.S under /cpu/mips/ is run for several mips cores, like 4kc, au1100,etc. if i port u-boot to 4kec, need i make a new directory in /cpu or just modify the old start.S in /cpu/mips/? and i wonder how difficult to port u-boot to 4kec,because i must finish it by the deadline,has someone succeeded in porting u-boot to 4kec?

[U-Boot-Users] U-boot hangs in smc_putc
by Will Haines 12 Jul '05

12 Jul '05

I am currently having the problem that my EP885C port of u-boot hangs in serial.c's smc_putc function at the point where it loops until the serial port is ready. I have scoured the past archives, and the best that I can get is that this could be a baud rate or port selection problem. For my EP885C board, I have the baud rate set at 9600, which I am nearly 100% sure is correct. I have CONFIG_8xx_CONSOLE_SMC1 set as 1, which I also believe to be correct. Are there any other reasons why the serial port would never be ready? Thank you for the help on this and my other previous posts. Will Haines

[U-Boot-Users] PATCH: Add sandburst metrobox board support [1/3]
by Travis B. Sawyer 12 Jul '05

12 Jul '05

[Note: My previous submission was rejected due to size] This patch adds the Sandburst Metrobox and Sandburst Karef Boards. Both are PPC440GX based, direct peripheral bus connected compact flash, dallas rtc, write protected eeprom (strappings and ethernet MAC address). EMAC 2 is the management ethernet interface, EMAC 3 goes to a board to board connector. These boards are reference designs for the Sandburst HiBEAM chipset. See http://www.sandburst.com for more board information (predominately marketing speak). This patch is against source forge cvs 12July2005, at approximately 0900 EDT. CHANGELOG: * Patch by Travis B. Sawyer, 12 Jul 2005: Add Sandburst Metrobox and Sandburst Karef board support packages. Second serial port on 440GX now defined as a system device. Add 'Short Etch' code for Cicada PHY within 440gx_enet.c Best regards, Travis Sawyer

[U-Boot-Users] Setting up reset on the EP885C
by Will Haines 12 Jul '05

12 Jul '05

Hello, I am still trying to get my port of u-boot to the EP885C to run. When I use the Planet Core bootloader on this board it seems to execute from address 0xFC000000 in flash, so I set the text base and monitor base to this value. When I program the binary to the board using a BDM, I can see the u-boot string at 0xFC000000. However, when I try to run from 0xFC000000 or 0xFC000100 I get no display at all, and the BDM reads -TARGET: STOPPED. Also, when I try to just program to flash and then reset the board it seems as if no code is executing. Can anyone verify that 0xFC000000 is the correct flash location for an EP885C? Also, I am thinking that by resetting the hard reset configuration word, I could force the board to jump to the correct instruction location, but I am at a loss to figure out how to change the hrcw's value. Any help would be greatly appreciated--I can't test to see what works if the code won't even execute. Thanks in advance, Will Haines

I hadn't much time to analyze what's going wrong but I think the problem was that the kernel (linuxppc_2_4_devel from denx) tried to mount the root file system _before_ initializing of the usb sub system has completed. At least the console messages looked so - but perhaps I missed something. Has anybody else tried this? I would be happy to hear about a successful way to do this. Regards, Martin

[U-Boot-Users] EMAC2 & EMAC3 operation on PPC 440GX
by David Grab 12 Jul '05

12 Jul '05

Hello, as mentioned before i´m using two Marvel 88E1111 PHY on my PPC440GX Board. They are configured as a RGMII to copper interface for use with EMAC 2 & 3. So now i´m in trouble with the configuration of the network. After booting i set with "setenv ethact ppc_440x_eth2" EMAC2 for networking. After that i try a "ping" to know if network is working. Reading the speed and duplex from PHY works, but after that i got in an endless loop. I figured out, that no interrupt is recognized and in 440gx_enet.c in ppc_440x_eth_init the default configuration of the interrupt handler is for ETH0: irq_install_handler (VECNUM_EWU0 + (hw_p->devnum * 2), (interrupt_handler_t *) enetInt, dev); irq_install_handler (VECNUM_ETH0 + (hw_p->devnum * 2), (interrupt_handler_t *) enetInt, dev); so i changed it as following... irq_install_handler (VECNUM_EWU2 + (hw_p->devnum * 2), (interrupt_handler_t *) enetInt, dev); irq_install_handler (VECNUM_ETH2 + (hw_p->devnum * 2), (interrupt_handler_t *) enetInt, dev); and added in vecnum.h these lines: #define VECNUM_ETH2 (64 + 0) /* Ethernet 0 interrupt status */ #define VECNUM_EWU2 (64 + 1) /* Ethernet 0 wakeup */ But this didn´t solve the problem. Actually i also couldn´t get the TxCLK work on my RGMII Bridge and i don´t know why. The devices are configured as 100 MBit RGMII and receiving packets from network seems to be functioning (EMAC_OCRX Register increments rapidly). I would be appreciated if someone could give me a tip, what i have forgot to do. Greets, David

[U-Boot-Users] EP885C Port Compilation Problems
by Will Haines 12 Jul '05

12 Jul '05

Hello everyone, I am trying to port U-Boot to an EP885C development board in order to practice porting before I have to port to a board that my company is in the process of building. I know that Yuli Barcohen will soon release a patch that ports to the EP885C, but I felt that I had to plow ahead before I get that patch as a reference for porting. I began by making the directories suggested in the faq and changing values for what board specifications I could determine. I am sure that I am missing some important values, but I wanted to test compilation. Upon doing so, I received the following errors as the compiler attempted to build u-boot.map: ****************************************************************************** net/libnet.a(net.o)(.text+0x11c): In function `ArpRequest': /shared/streamblade/test/wdhaine/workdir/u-boot-1.1.2/net/net.c:217: undefined reference to `eth_send' net/libnet.a(net.o)(.text+0x11c):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:217: relocation truncated to fit: R_PPC_PLTREL24 eth_send net/libnet.a(net.o)(.text+0x2a8): In function `NetLoop': /shared/streamblade/test/wdhaine/workdir/u-boot-1.1.2/net/net.c:287: undefined reference to `eth_halt' net/libnet.a(net.o)(.text+0x2a8):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:287: relocation truncated to fit: R_PPC_PLTREL24 eth_halt net/libnet.a(net.o)(.text+0x2b0):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:291: undefined reference to `eth_init' net/libnet.a(net.o)(.text+0x2b0):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:291: relocation truncated to fit: R_PPC_PLTREL24 eth_init net/libnet.a(net.o)(.text+0x38c):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:457: undefined reference to `eth_rx' net/libnet.a(net.o)(.text+0x38c):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:457: relocation truncated to fit: R_PPC_PLTREL24 eth_rx net/libnet.a(net.o)(.text+0x404):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:515: undefined reference to `eth_halt' net/libnet.a(net.o)(.text+0x404):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:515: relocation truncated to fit: R_PPC_PLTREL24 eth_halt net/libnet.a(net.o)(.text+0x494):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:463: undefined reference to `eth_halt' net/libnet.a(net.o)(.text+0x494):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:463: relocation truncated to fit: R_PPC_PLTREL24 eth_halt net/libnet.a(net.o)(.text+0x648): In function `NetStartAgain': /shared/streamblade/test/wdhaine/workdir/u-boot-1.1.2/net/net.c:551: undefined reference to `eth_halt' net/libnet.a(net.o)(.text+0x648):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:551: relocation truncated to fit: R_PPC_PLTREL24 eth_halt net/libnet.a(net.o)(.text+0x73c): In function `NetSendPacket': /shared/streamblade/test/wdhaine/workdir/u-boot-1.1.2/net/net.c:604: undefined reference to `eth_send' net/libnet.a(net.o)(.text+0x73c):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:604: relocation truncated to fit: R_PPC_PLTREL24 eth_send net/libnet.a(net.o)(.text+0x8b0): In function `NetSendUDPPacket': /shared/streamblade/test/wdhaine/workdir/u-boot-1.1.2/net/net.c:653: undefined reference to `eth_send' net/libnet.a(net.o)(.text+0x8b0):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:653: relocation truncated to fit: R_PPC_PLTREL24 eth_send net/libnet.a(net.o)(.text+0xc60): In function `NetReceive': /shared/streamblade/test/wdhaine/workdir/u-boot-1.1.2/net/net.c:1280: undefined reference to `eth_send' net/libnet.a(net.o)(.text+0xc60):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:1280: relocation truncated to fit: R_PPC_PLTREL24 eth_send net/libnet.a(net.o)(.text+0xcf0):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:1251: undefined reference to `eth_send' net/libnet.a(net.o)(.text+0xcf0):/shared/streamblade/test/wdhaine/workdir/ u-boot-1.1.2/net/net.c:1251: relocation truncated to fit: R_PPC_PLTREL24 eth_send make: *** [u-boot] Error 1 ****************************************************************************** If someone could help me determine how to make the build process find the eth functions (I see that their code is located in net/eth.c) I would be very appreciative.

[U-Boot-Users] Help debugging a PCI scanning problem
by Richard Danter 11 Jul '05

11 Jul '05

Hi all, I have almost completed the porting of U-Boot to my 7400/107 board. I am now able to boot from flash, tftpload the hello_world example and run it. :) However, there is a hack which I don't like and hope maybe someone can suggest why I need it and what the _correct_ solution is. When eepro100_initialize() is called it loops scanning the PCI bus for cards. I have such a card and it is found with no problems. The card is initialised correctly which is how I am able to tftpload the example. The problem comes after it has initialised the card. It looks for a second card and this seems to crash the system. For the moment I have added the following to the end of the eepro100_initialize() function: read_hw_addr (dev, bis); #ifdef CONFIG_PPMC7xx /* RAD * FixMe: This prevents a crash but means only * one network card can be installed */ break; #endif } return card_number; } which works. I can scan the bus with the "pci" command and get the following results. Obviously the network controller Dev number changes depending on which slot it is inserted into: => pci Scanning PCI devices on bus 0 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 00.00.00 0x1057 0x0004 Bridge device 0x00 00.11.00 0x8086 0x1030 Network controller 0x00 00.12.00 0x1011 0x0026 Bridge device 0x04 => There are only 2 slots on this board. The ethernet card works in either of them. The crash seems to happen within the pci_find_devices() function. Any suggestions how I can debug this? Many thanks Rich

Hi all i'm actually trying to use a LXT971 on a arm rm9200 based based board so i'm using the at91r9200dk_config to compile the sources i've just changed the dm9161.c and dm9161.h files to match the good register (dm9161.h contents is replaced by the one of lxt971a.h). I've put these two files in the mail So the PHY component is well detected, so as the connection properties (10/100 Half/Full-Duplex) but when i try to ping a foreign device (i've activate the ping function) or if i try to use tftp to download file, nothing is happening (no connection on the tftp server are detected) So does anybody have an idea about how to make the network component working? -- Cordialement Fabrice & Frédéric -- IFOTEC Tél : 04 76 67 53 53

[U-Boot-Users] Question on FEC Parameter Ram structure
by Srivatsan CR 08 Jul '05

08 Jul '05

Dear all, The Ethernet protocol RAM area structure defined in include/asm/cpm_8260.h is taking 8 bytes of additional space due to "ushort rfthr" and "ushort rfcnt". These are not part of FEC parameter RAM area as per the MPC8260 / MPC8280 datasheet.Also as per the data sheet the size of the FCC (Ethernet) parameter area can be only 0xFF, due to these parameters the size is greater than 0xFF by 8 bytes. Just wanted to know was there any consideration for putting these fields in the FEC parameter RAM area or is it a mistake? Thanks for your understanding. With Regards, C.R.Srivatsan

[U-Boot-Users] kernel global variable debug
by kuiliang shi 07 Jul '05

07 Jul '05

Dear All: My board's cpu is freescale 8247. I debug the linux kernel 2.4.26 with BDI2000 and ppc_6xx-gdb on it. My linux kernel text base on 0xC0000000, so some global variable at 0xCxxxxxxx virtual address. Now the problem is that I can not print the global variable's value, when i use "p" command in gdb: p /x ga. gdb always tell me it's zero, even if I directly print the content in the ga's address. But if I evaluate the ga's value to a local variable in programm, then print it in gdb, it can get me the correct value. It seems the global variable was processed correctly. But Why I can not get the value? where the global variable stored while kernel running?

[U-Boot-Users] No boot prompt on Ebony 440GP board
by Gregg Lastname 07 Jul '05

07 Jul '05

I have a PPC440GP evaluation board ("Ebony"). I used the buildroot tools from buildroot.uclibc.org to build a cross compiler based on gcc 3.4.4. I then built u-boot by issuing make EBONY_config make which built u-boot without any errors. I then wrote the resulting u-boot.bin file to flash using a JTAG programmer. I set the DIP switches and jumpers according to the README.ebony instructions. When I power the board up, the following console text is generated: ----begin console output----- U-Boot 1.1.2 (Jul 6 2005 - 15:51:04) IBM PowerPC 440 GP Rev. C Board: IBM 440GP Evaluation Board (Ebony) VCO: 600 MHz CPU: 300 MHz PLB: 100 MHz OPB: 50 MHz EPB: 50 MHz I2C: ready DRAM: I2c read: failed 4 I2c read: failed 4 128 MB -----end console output----- and then nothing more happens. No prompt is displayed. I tried the J41/J42 bootstrap corruption directions, but it did not seem to have any effect. Could someone suggest what to do next? I assume I am supposed to receive a prompt that enables me to enter interactive commands. Is that correct? Thanks.

[U-Boot-Users] USB booting...
by Neil Bryan 06 Jul '05

06 Jul '05

I am attempting to boot Linux on a target platform using a USB mass storage device (flash disk) to hold the kernel and the root filesystem. I thought it may be a good idea to replicate the same steps used when booting from a tftp server, i.e. I copy the root filesystem (using an initrd image) to an address in RAM, then copy the kernel to a different address in RAM. Finally bootm with the start address of the kernel. Bootargs will be set during this process. So I created two partitions on the USB flash disk, partion 1 holds the kernel image and partition 2 holds the initrd image. The partition table looks like this: Disk /dev/sdb: 32 MB, 32768000 bytes 2 heads, 32 sectors/track, 1000 cylinders Units = cylinders of 64 * 512 = 32768 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 154 4912 83 Linux /dev/sdb2 155 308 4928 83 Linux My file sizes are: initrd: 1203800 bytes. uImage: 2285056 bytes. The command I want to use to copy the initrd is: usb read 20800000 x y. Where 20800000 is the address for the initrd to be copied to, x will be the block-offest to the start of partition 2 and y will be the size in blocks of the initrd image. Now I need to calculate the block-size based on cylinders, heads, units etc. My questions are, am I making this too complex, is there an easier way to achieve the same result of booting using a USB flash disk with seperate kernel/initrd images? Appologies for the long-winded pre-amble, but I don't know how to ask a question like this without describing the problem. Thanks for any insight, Neil.

[U-Boot-Users] Problem starting u-boot on Xilinx V2P
by Thorsten Lueck 06 Jul '05

06 Jul '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have a own board with an Virtex V2Pro (V2P30) an want to boot u-boot on the PPC. Starting from the demo-design for the ml300 demo board, I managed to compile u-boot 1.1.1 (1.1.2 fails when running the tcl-script with EDK 7.1) and could download and run u-boot on my PPC. However, u-boot stops after printing U-Boot 1.1.1 (Jul 5 2005 - 16:50:28) ### No HW ID - assuming ML300 DRAM: 128 MB I get no further output afterwards. Another strange thing is, that I only have 32MB RAM on board but not 128MB as the ml300 has. However, I could not find any hardcoded RAM size in the source files for the ml300. Does anybody has an idea? I found the comment : /* * WARNING: this code looks "cleaner" than the PowerPC version, but * has the disadvantage that you either get nothing, or everything. * On PowerPC, you might see "DRAM: " before the system hangs - which * gives a simple yet clear indication which part of the * initialization if failing. */ in the ./lib_i386/board.c, however, there is no appropriate warning in static int init_func_ram (void) of ./lib_ppc/board.c Thanks in advance, Thorsten Lück - -- IfEN - Gesellschaft für Satellitennavigation mbH Dipl.

RE: [U-Boot-Users] Tool chain for armv6
by Woodruff, Richard 06 Jul '05

06 Jul '05

http://www.codesourcery.com/ is a good spot and has done much of the front line work. ARM Ltd also had downloads on their web site. The current u-boot default for 2420 is set to ARMv5 now to allow more compilers to work. There isn't a strong need to have a v6 capable tool chain at this level. The only thing to watch out for is option usage change. There was a recent patch submission to the entire u-boot ARM tree which takes care of that.

[U-Boot-Users] Statuc code format for USB response...
by Neil Bryan 06 Jul '05

06 Jul '05

This is a trivial comment, but helpful for developers not expert in debugging USB-related problems. After issuing the following command: U-Boot> usb reset I obtained the following result: USB device not responding, giving up (status=20) The code responsible for this is in ./common/usb.c and shown below: printf("\n USB device not responding, giving up (status=%lX)\n",dev->status); I _believe_ the status code returned is that defined in ./include/usb_defs.h and that my status code of 20 is the value defined by the macro USB_ST_CRC_ERR. The printf uses a %lX format specifier and it would be improved if it was proceeded with an '0x' to inform the developer (me) that this is indeed a hexadecimal value. My suggested change is In ./common/usb.c -------------- - printf("\n USB device not responding, giving up (status=%lX)\n",dev->status) + printf("\n USB device not responding, giving up (status=0x%lX)\n",dev->status) -------------- As I said, I know this is trivial, but every little bit of extra information helps when debugging something that is unfamiliar. Flames and other comments gratefully received! Regards, Neil Bryan.

[U-Boot-Users] Help with crash

05 Jul '05

Hi All, I have been making some progress with porting U-Boot to a 7400/107 board. I now have serial out, but crash before the code is relocated to RAM. Can anyone help me please? The last thing I see on the serial console is: Reserving 48 Bytes for Global Data at: 03fc9f98 I think the address looks OK as I have 64MB RAM on this board so Global Data is just below the top of that. This is where I get to in lib_ppc/board.c: /* * Finally, we set up a new (bigger) stack. * * Leave some safety gap for SP, force alignment on 16 byte boundary * Clear initial stack frame */ addr_sp -= 16; fff036b4 subi r31,r26,0x1078 fff036b8 crclr cr6 fff036bc bl printf debug ("Reserving %d Bytes for Global Data at: %08lx\n", fff036c0 li r4,0x30 fff036c4 lwz r3,-0x7FC4(r30) fff036c8 mr r5,r24 addr_sp &= ~0xF; fff036cc clrrwi r31,r31,4 fff036d0 crclr cr6 fff036d4 bl printf fff036d8 mr r11,r31 fff036dc subi r31,r31,4 fff036e0 stw r25,__fixup_entries(r11) <== Crash here *((ulong *) addr_sp)-- = 0; debug ("Stack Pointer at: %08lx\n", addr_sp); fff036e4 lwz r3,-0x7FC0(r30) fff036e8 stw r25,__fixup_entries(r31) fff036ec subi r31,r31,4 fff036f0 mr r4,r31 fff036f4 crclr cr6 fff036f8 bl printf When I step through the instruction at fff036e0 I end up at 700, which is the Program Exception vector (srr0 = 0x800, srr1 = 80000) which implies an illegal instruction?

Just a few more questions if you have the time. 1. Is there a document in U-boot or in your website that discuss the x86 emulation? 2. For my own verification, is the x86 emulation code located in board/MAI/bios_emulator? 3. Is there any other boards that you know of that uses this x86 emulation other than the AmigaOneG3SE? 4. Would there be a switch to just enable the x86 emulation in U-boot (i.e. CONFIG_X86_EMULATION)? There is probably no such thing but I'd rather get the correct information from you. Again, thank you for all the answers to my questions. Regards, Maynard

Hello group, I have searched the mailing list and know this question has been asked before, but it was six months ago and the situation may have changed. Has anyone added USB-support for the ATMEL AT91RM9200 in U-boot but has not sent the changes to be intergrated into U-Boot? I have checked the CVS-head and cannot see support for USB, so I presume it is not there. However, before I embark on a long and painful battle, I thought I would ask! Thanks in advance, Neil.

Hi all i'm actually trying to use U-boot on my board that is based on the RM9200EK from Atmel so when i configure it, i use the at91rm9200_config option but due to the fact that the Flash chip and the PHY chip are different they are not detected. I'm using a AT49BV6416T (AT49BV6416 on the board from Atmel) and an Intel LXT971ALE A4 (Davicom on the board) So does any body have an idea on how about to make these chips detected? For the Flash Chip i've change the device id to go with the T flash (#define ATM_ID_BV6416 0x000000D6 >>> #define ATM_ID_BV6416 0x000000D2 in the flash.hfile) and the flash organization ( OrgDef OrgAT49BV6416[] ={ { 8, 8*1024 }, { 127, 64*1024 },}; >>> OrgDef OrgAT49BV6416[] ={ { 127, 64*1024 }, { 8, 8*1024 },};) with regards -- Frédéric Kwiatkowski -- Plateforme Technologique Valence Tél : 04 75 41 88 58

[U-Boot-Users] cfi_flash is now working with 64 bit port width
by Yusuf Ibrahim Ozkok 02 Jul '05

02 Jul '05

Hi, I have resolved my problem with cfi_flash driver. I would like to share what I have learned during my struggle with cfi_flash driver. The posts for that problem; http://sourceforge.net/mailarchive/message.php?msg_id=11994639 http://sourceforge.net/mailarchive/message.php?msg_id=12058552 What caused the problem and how is it solved: Flash chips in my board are connected to 64 bit data bus. And the problem is simply about writing 64 bit data at once. cfi_flash driver used "unsigned long long" variables for 64 bit data and write them to the bus simply using long long pointers (For me that is a bug. And I would like to release a patch for it). Any integer definition (like int, long, long long etc.) makes gcc to use 32 bit registers of the cpu (for 32 bit ppc's). Long long is 64 bit on the memory that is true, but transfering a long long requires two cycles. To write a 64 bit data at once we have to use floating point registers. A way of using these registers in C is to define the variables as "double". But somehow defining double didn't work in u-boot or with my ppc_82xx-gcc compiler (eldk's compiler). An other way is to use assembly floating point instructions but double precision forms. Such as "lfd" and "strfd" commands for ppc have to be used. Jerry Van Baren had warned me previously but I couldn't make sense with his suggestions at the moment. What make me confused that writing flash commands from u-boot shell by using mw.l command was working for protect and erase operations. Since mw.l makes 32 bit bus transaction, for example a 0x60606060 command was beeing recognized by all the four flash chips. On the other way a 0x00600060 command is caused failure (I had expected that it will work two out of four flash chips). Now when I solved the problem by using floating point registers, I understood Jerry's suggestions exactly! You can reach his post by the link. (http://sourceforge.net/mailarchive/message.php?msg_id=11994640) But I still can not solve the magic that while sending 0x60606060 by mw.l command works but 0x00600060 not! Lessons: So lesson-1: if hardware people gives you a 64 bit bus, use double or directly asm floating point instructions. I think cfi_driver works with the boards that the flash chips are selected by chip select signals for each 32 bit portion of the data bus. In our board all the flash chips are connected to the same chip select signal that caused the problem. Lesson-2: first of all examine your hardware well and be aware of your hardware. Thanks for your help: Jerry Van Baren, Yuli Barcohen, Richard Woodruff. The patch (unformatted): 1. The following function is added. static void write_via_fpu (vu_long * addr, ulong * data) { __asm__ __volatile__ ("lfd 1, 0(%0)"::"r" (data)); __asm__ __volatile__ ("stfd 1, 0(%0)"::"r" (addr)); } 2. in /drivers/cfi_flash.c line 850; - *addr.llp = cword.ll; + write_via_fpu((vu_long*)addr.llp, (ulong*)&cword.ll); line 1159; - cptr.llp[0] = cword.ll; + write_via_fpu((vu_long*)cptr.llp, (ulong*)&cword.ll); P.S. this function will work if fpu is enabled. If not it may be enabled by setting the fpu bit in msr as follows; unsigned long msr; msr = get_msr(); set_msr(msr | MSR_FP); *_msr functions may be found by grepping the uboot directory. 3. The patch is not tested when CFG_FLASH_USE_BUFFER_WRITE is defined. Same changes as in 2 should be done for that case. If those changes are accepted, I can arrange a formal patch. Finally, I would like to ask about the Tolunay Orkun's patch about tout in flash_status_check function. what is the last thought for that patch Is it planned to be released? Because it's really a bug! (Last post for the thread; http://sourceforge.net/mailarchive/message.php?msg_id=11936556) Best Wishes.

[U-Boot-Users] PCI video display in MPC8270
by Maynard Cabiente 02 Jul '05

02 Jul '05

Hi All, We currently just enabled the PCI bus on our MPC8270 custom board. We intend to put a video chip in the PCI bus (XGI Volari Z7). For testing, we got the Z7 PCI demo board. We are using u-boot and Linux kernel 2.4.25 in our system. I had a pre-conception that the Linux kernel will be able to handle the VGA console by itself without any BIOS help (or in this case U-boot). After configuring the kernel to support VGA console, the PCI video card did not give any display (probably no sync at all). AFAIK, the PCI bus is working correctly. I did test a Netgear PCI network card to verify it (and it passed). The Z7 demo card works ok on a regular Linux PC with a standard BIOS on it. 1. Does our system require a VGA BIOS (aside from U-boot) to display console (and later on to display a GUI, i.e. X Windows, Tiny X)? 2. Is it possible to configure the Kernel to do the PCI video card initialization without involving U-boot so that it will at least display a VGA console 80x25? 3. Do I actually need to write a driver for the Z7 in U-boot (similar to CT9000, SMI 710/712/810) to configure the video chip correctly before Linux takes over? 4. I still like to send U-boot console messages to the MPC8270 (SCC) serial port and just start the VGA console once Linux takes over. Is this possible? I greatly appreciate any insights about this issue. thanks in advance, Maynard

Re: [U-Boot-Users] Does u-boot relocate absolute symbols?

Jerry: I'm sorry for the inconvenience, but sent this mail to you instead of the U-Boot mailinglist. I'm not quite sure, what happened on your side. Here's the result on my side (together with the source as it ought look): --- BEGIN OF CONSOLE OUTPUT andreas@pc-linux-dev:~/arrtest> cat common.h int showwrong(void); andreas@pc-linux-dev:~/arrtest> cat common.c #include <stdio.h> extern const unsigned char test[]; int showwrong(void) { printf("test[]: 0x%08X\n", (int)test); return 0; } andreas@pc-linux-dev:~/arrtest> cat array.c #include "common.h" const unsigned char *test = (unsigned char*)0x40000; int main(void) { printf("*test: 0x%08X\n", (int)test); showwrong(); return 0; } andreas@pc-linux-dev:~/arrtest> gcc -o arrtest -I ./ ./common.c ./array.c andreas@pc-linux-dev:~/arrtest> ./arrtest *test: 0x00040000 test[]: 0x080494E4 --- END OF CONSOLE OUTPUT What buffles me is, that on your side, the *test-output isn't 0x40000, because the pointer is initialized directly in that object and used as pointer. And on the other hand, the output can't be the same: extern char test[]; ==> results in a symbol at the start address of the array. char *test; ==> is a pointer containing the start-address of the array. This means one more level of reference. Could you please show your source files as they were used for your test to us. I'm still sure, both notations are not the same, although they work the same in most cases.

[U-Boot-Users] uboot on pq2fadsvr
by eagle keeper 01 Jul '05

01 Jul '05

Hi all, and sorry for my question. I have not very clear what to do to compile uboot for pq2fadsvr with mpc8275 processor. I mean: it is an evaluation board supported by uboot isn't it? And if so, why doesn't exist a configuration file? Is it enought to lighlty modify the 8260ads configuration file? And wich entries? Thank in advance Lele

Actually your suggestion is the way it's currently working here, but as I described in my first post, I'm looking for a way, which leaves the common code untouched. In my first post on 24.06.05 I've another solution, which is working for Linux, but does not in U-Boot. Regards, Andreas >> Sure, I've tried this.
