RE: [U-Boot-Users] Re: [Question About NAND BOOT In SMDK2410
by Woodruff, Richard 29 Oct '03

There are a few processors which actually can "boot" from NAND. The OMAP161x is one such processor. It has hardware NAND support for ECC and fetching this along with some microcode in an internal mask ROM (on chip) can load up and execute code contained in Nand for boot. http://siliconvalley.internet.com/news/print.php/2224021 There is also a couple "integrated" chips which also allow booting from a "mainly" a nand device, like disk on chip and SuperNAND. http://www.m-sys.com/Content/Products/mobileDocPlusDiagram.asp As for what the SMDK2410 board is capable of, I have no idea.

Hi all, I've found unexpected code inside of smc_send_packet() in file drivers/smc91111.c (near line 585-590): /* send the packet length ( +6 for status, length and ctl byte ) and the status word ( set to zeros ) */ #ifdef USE_32_BIT SMC_outl ((length + 6) << 16, SMC91111_DATA_REG); #else SMC_outw (0, SMC91111_DATA_REG); /* send the packet length ( +6 for status words, length, and ctl */ SMC_outw ((length + 6), SMC91111_DATA_REG); #endif This code assembles the header of a data frame for transmission. My SMSC manual says about the BYTE COUNTER: "... alway even ...", Hmm , this code will put in even and odd length arguments. "length" should be replaced with "(length & 0xfffe)", the same code at top of function for page number calculation. What's your opinion?

28 Oct '03

Thanks for your reply Wolfgang, > > Try what happens when you "#define CONFIG_NET_MULTI" in your board > config file. The primary interface can be selected using the > "ethprime" environment variable. Here is a quick snippet of the config file :- /* * select ethernet configuration */ #undef CONFIG_ETHER_ON_SCC /* define if ethernet on SCC */ #define CONFIG_ETHER_ON_FCC /* define if ethernet on FCC */ #undef CONFIG_ETHER_NONE /* define if ethernet on neither */ #define CONFIG_NET_MULTI #define CONFIG_ETHER_ON_FCC1 #define CONFIG_ETHER_ON_FCC2 #define CFG_CMXFCR_MASK1 (CMXFCR_FC1|CMXFCR_RF1CS_MSK|CMXFCR_TF1CS_MSK) #define CFG_CMXFCR_VALUE1 (CMXFCR_RF1CS_CLK10|CMXFCR_TF1CS_CLK9) #define CFG_CMXFCR_MASK2 (CMXFCR_FC2|CMXFCR_RF2CS_MSK|CMXFCR_TF2CS_MSK) #define CFG_CMXFCR_VALUE2 (CMXFCR_RF2CS_CLK14|CMXFCR_TF2CS_CLK13) To be honest this is all I had to change, the addition of the ethprime env variable certainly helps as well, I'm not sure that I understand the intention of the code though. I was expecting the interfaces to be available similtaneously such that I could switch between them, perhaps this is not the case. I'll illustrate by using an example :- U-Boot 0.4.0 (Oct 27 2003 - 12:28:40) MPC8260 Reset Status: Software Watchdog, External Soft, External Hard MPC8260 Clock Configuration - Bus-to-Core Mult 4x, VCO Div 2, 60x Bus Freq 25-75 , Core Freq 100-300 - dfbrg 1, corecnf 0x1a, busdf 5, cpmdf 1, plldf 0, pllmf 2 - vco_out 396000000, scc_clk 99000000, brg_clk 24750000 - cpu_clk 264000000, cpm_clk 198000000, bus_clk 66000000 CPU: MPC8260 (Rev 14, Mask B.1 4K25A) at 264 MHz Board: Arca Technologies 82xx, Revision 0.0 I2C: ready DRAM: 128 MB FLASH: 8 MB In: serial Out: serial Err: serial Net: FCC1 ETHERNET, FCC2 ETHERNET [PRIME] BEDBUG:ready Hit any key to stop autoboot: 0 /******Ping using FCC2*******/ => ping 192.168.0.121 host 192.168.0.121 is alive /******Now disconnect FCC2*******/ /******Ping using FCC1*******/ => ping 192.168.0.121 ping failed; host 192.168.0.121 is not alive => If I switch the ethprime variable to FCC1 then reboot FCC1 works but FCC2 doesn't. Like I mentioned perhaps the problem is my understanding of the intention of the code rather than any misconfiguration on my part. > > > Any takers? > > Me? > And I'm eternally grateful! :) It makes life a lot more bearable knowing that someone out there knows the solution to every problem!

Hi Stephan, I'm glad to hear other Nios users are discovering u-boot :-) U-Boot and Nios is a great combination! > But now, I can't setup my network environment in expected way. > The u-boot environment vars "ethaddr", "iptable", "netmask", and > "serverip" are correct in flash, but bdinfo shows me the default > values (compiled in) -- Why ? Looks like I screwed up the call sequence in lib_nios/board.c ... the code is calling getenv("ethaddr") prior to env_init() -- must have been a late night ;-) The fields that depend on an initialized environment should be initialized _after_ calling the routines in init_sequence ... which includes env_init(). Try moving bi_ip_addr and bi_enetaddr below the init_sequence loop. I'm out-of-office so I can't work on a patch for a few days. If the changes work, please submit a patch to Wolfgang -- or we can work together off-line. Regards, --Scott

[U-Boot-Users] U-boot automatic selection of redundant ethernet interfaces?
by Mark Doherty 27 Oct '03

27 Oct '03

Hello u-boot-users, First a bit of background, I am using a custom processor board (similar to the ep8260) which has u-boot-0.4.0 running very nicely on it. The board has two ethernet interfaces which provide functionality like network address translation etc. Both interfaces are configured correctly, I know this as I have been using fcc2 and have only recently enabled fcc1 which is now the main port for the system. Now that both interfaces are configured I find that I can only use fcc1 for activities such as tftp etc. I have configured different eth addresses for both ports but I can't seem to get the system to use fcc2 rather than fcc1.The README does state that "u-boot is capable of automatic selection of an interface when needed", but I've not had much luck finding more information. Any takers? Regards Mark Doherty.

[U-Boot-Users] U-Boot for AT91RM9200DK
by Steven Scholz 27 Oct '03

27 Oct '03

Hi Rick et al., as I mentioned before U-Boot is running on our AT91RM9200 based board. I went down the path ATMEL was suggesting. They use this memory map on their eval board AT91RM9200DK: 24k Boot Image 32KB free 8KB Environment 64KB gzipped U-Boot image The "Boot image" is a small (11k) piece of code which initialises clocks, flash, SDRAM and serial port. Then it decompresses the "gzipped U-Boot image" into SDRAM and jumps to it. The reason for that seems to be: > We chose, to put a compressed boot due to memory mapping constraints. > We need to keep a sector for environment variables the 8Kbyte-size sector is > enough. They probably overlooked that you could embedded the environment into U-Boot. By using a correct u-boot.lds linker file one can reserve an 8Kbyte-size sector in the middle of U-Boot. So instead one could use this memory map: 56KB U-Boot 8KB Environment 64KB U-Boot using the same 128KB of flash. Since the CPU was setup by the bootloader there's no init and relocation code for the AT91RM9200 in U-Boot (yet). So I spend a day, "wrote" some init and relocation code and now U-Boot is starting directly from flash and relocates itself to RAM. No Preboot needed. Nor gzipped image of U-Boot. I would like to change the official U-Boot code for the AT91RM9200 and AT91RM9200DK so that it can be used without the need of another bootloader. This way it would be a lot easier for people to port U-Boot to their hardware. What do you think? Anyone interessted? I'd love to hear suggestion, where to put specific parts of the init code. Other ARM cpus use a board specific memsetup.S file. For an AT91RM9200 we have to setup more than just the SDRAM. Should we put all the init code into cpu/at91rm9200/{start.S} and use CONFIG_ and CFG_? Or should every AT91 based board copy the same code again and again into thier own subdirectory? Looking forward to your ideas! Thanks.

Hi Scott and all other NIOS people, today I've successfully brought up and running the U-Boot NIOS port on a Stratix Development Kit (DK-1S10). Thanks to Scott -- was (is) a great work. The preconfigured Cyclone Edition was running and startup without critical problems, because as far as I know the Stratix edition is 100% equal to Cyclone except the FPGA. But now, I can't setup my network environment in expected way. The u-boot environment vars "ethaddr", "iptable", "netmask", and "serverip" are correct in flash, but bdinfo shows me the default values (compiled in) -- Why ? (logfile see attachment) Has anybody similar problems on Cyclone, or is it a Stratix problem (may be an useless question) ? Where can I found the setup flow from saved environment to bdi structure inside the u-boot source code? I want to check up the settings step by step. Ah: I'm using u-boot cvs snaphot date 20031024.

by cyborg＠embyte.net 26 Oct '03

26 Oct '03

Hello there, I'm trying to get U-Boot running on a Motorola MBX821-001 board. But up to now i couldn't manage it. After downloading U-Boot and flashing it (according to a ml thread of ppcboot-users: http://www.geocrawler.com/archives/3/4205/2001/12/0/7301427/ ) the MBX Board doesn't do anything but output wired characters on serial console. I've read the docs/README.MBX but it doesen't help. Has anyone successfully got U-Boot (or PPCboot) running on a MPC821 (or better on MBX821-001)?? Any hints or suggestions? Thanks in advance.

[U-Boot-Users] RESET on Lite5200
by Pascal FIFRE 25 Oct '03

25 Oct '03

I've used a Lite5200 (Version 2 : 64MB SDRAM, 16 MB FLASH) and I try to use U-Boot on It. I worked for now with a WireTAP JTAG debugger. I've flashed the latest code found in CVS tree and compile it with ppc_8xx. When I Reset (hard or soft reset) the cpu, the U-Boot doesn't work at all (I didn't see anything on the console). But when I use the debugger to reset the CPU and start the code in FLASH, U-boot works fine. The board has the default RESET configuration (Boot High, etc.). In the same way, when I flash the MOTOROLA DBBUG monitor on the board and RESET, it works. Can you help me ? Thanks

[U-Boot-Users] U-Boot and PPC

Hello, I just found this list, so please bear with me if my questions are basic. I'd like to use the 440GX (or 440GP) so I got the ELDK and U-Boot 0.4. The ELDK doesn't specifically say that it supports the 440 series, do you know if anyone has been successfuly in building 440 binaries using ELDK? Also, I've never used U-Boot before, but I'm *assuming* that once I get U-Boot running on my board, I can just load up the application built with ELDK (assuming of course the it can build 440 compatible binaries) and it should work? Am I completely missing something here? Intially, I just want to get a simple "hello world" program working (ie, not attempting to boot Linux yet) Thanks very much for your time! Sri

[U-Boot-Users] Multi-file problem
by Rick Bronson 23 Oct '03

23 Oct '03

Hi, I found a problem with Mutli-file use of mkimage (using "-T multi") and fixed in my old u-boot-0.4.0 but my fix seemed to filter through too many files when I tried to do it (more correctly) on the cvs tree. Here's the problem (using 21-Oct-03 cvs files): When this address in cmd_bootm.c:1122 inside print_image_hdr() (is caculated: ulong *len_ptr = (ulong *)((ulong)hdr + sizeof(image_header_t)); it points to memory that wasn't copied back on cmd_bootm.c:174: memmove (&header, (char *)addr, sizeof(image_header_t)); because len_ptr points to the address header[1] and the memmove only moved header[0]. So I changed line 140 to: image_header_t header[2]; /* enough room for multi-image's size bytes too */ and all occurances of memmove (&header... from: memmove (&header, (char *)addr, sizeof(image_header_t)); to: memmove (&header, (char *)addr, sizeof(header)); But cmd_autoscript.c,common_util.c, armlinux.c uses &header and I'm not sure if this is the right fix. Maybe someone who knows this stuff can give me some direction. Thanks much. Rick

[U-Boot-Users] ICACHE and ARM ???
by Steven Scholz 23 Oct '03

23 Oct '03

Hi there, my new board using Atmel's AT91RM9200 is booting now straight up to the bash! But I noticed that the cache is _not_ enabled while U-Boot is running. That makes tftp und bootm very slow indeed. Now, enabling and disabling icache by accessing CP15, Reg 1 using a BDI2000 works fine. The speed up is remarkable. But the icache command does not work as I woud ecpect: MulitIO> icache p15/c1 is = c000007c Instruction Cache is OFF MulitIO> icache on icache_enable(145) p15/c1 is = c000007c write c000107c to p15/c1 p15/c1 is = 0000617c p15/c1 is = 0000617c Instruction Cache is OFF Hmm. So instead of just setting Bit 12 three other bits are set. Is someone using icache on ARM systems? Thanks. -- Steven Scholz imc Measurement & Control imc Meßsysteme GmbH Voltastr. 5 Voltastr. 5 13355 Berlin 13355 Berlin Germany Deutschland fon: +49 30 467090-0 Tel: 030 / 467090-0 fax: +49 30 4631576 fax: 030 / 4631576

RE: [U-Boot-Users] Problem with LAN91C113
by Scott McNutt 21 Oct '03

Rick, I had the exact same problem when using LAN91C111 on the Nios DK-1C20 board (same status & incorrect length). You may need to define CONFIG_SMC_USE_32_BIT. If your bus interface to the chip is 32-bits, a full 32-bit read might be occuring when the data register is read. This throws away the second 16-bit word of the packet buffer (which is the packet length) -- so you end up skipping every other set of 2-bytes after reading the incorrect length.

[U-Boot-Users] Successful Port to PrPMC800
by Mark.Lightfoot＠sita.aero 21 Oct '03

21 Oct '03

Hello, I've successfully ported U-Boot to the Motorola PrPMC800. Support for FLASH, PCI, IDE and networking have bee successfully enabled. It has been in use now for several weeks in a stable form. I do have one lingering problem of not being able to turn on the L1 and L2 data caches. Doing so apparently causes the system to hang. Unfortunately I don't have a BDI2000 setup for this board to better debug the problem. I used just a good ol' console and plenty of printf statements to do the port. I can't give a specific time for when I will have the port submitted for a future release of U-Boot. But I will do it. I'd like to fix my cache problem first and I have to finish the rest of the project for which U-Boot is just one part. And that may be awhile. Regards, Mark.

I'm investing the possibility of porting U-Boot to the Motorola PrPMC800 and possibly the Force Computer PowerPMC-260. As anyone already done the port to these boards? See URL: http://mcg.motorola.com/cfm/templates/product.cfm?PageID=925&ProductID=175&… And URL: http://www.forcecomputers.com/products/viewDetail.cfm?productTypeID=2&produ… The goal is to boot Linux from and IDE drive which the boot firmware of these boards do not support. I don't have the Motorola hardware yet ( delivery is six to eight weeks! ) but it is the intended hardware for the project I'm working on. I do have the Force Computer hardware right now. So, I may proceeded to port U-Boot to it first and do my the remainder of the Linux development work with it in the mean time.

[U-Boot-Users] How to optimize bit bang interface?
by Steven Scholz 21 Oct '03

21 Oct '03

Hi there, I am trying to configure an Altera FPGA using the so called "passive serial interface". Basicly it follows the scheme "clk low, data out, clock high". For testing I wrote the loop ts = get_timer (0); while (1) { if (get_timer (ts) > 10 * CFG_HZ) break; /* Deassert the clock */ (*fn->clk) (FALSE, TRUE, cookie); /* Assert the clock */ (*fn->clk) (TRUE, TRUE, cookie); }; fn->clk() is the function that the common FPGA code uses: int inline fpga_clk_fn(int assert_clk, int flush, int cookie) { if (assert_clk) *AT91C_PIOB_SODR = FPGA_DCLK; else *AT91C_PIOB_CODR = FPGA_DCLK; return assert_clk; } I noticed that this is awfully slow. I get arounf 50kHz using an AT91RM9200 running at 51MHz (core @ 171MHz). Could someone give me a hint how to optimize stuff like this for speed?

[U-Boot-Users] Problem with LAN91C113
by Rick.Lee 21 Oct '03

21 Oct '03

The Ethernet Chip on my board is SMSC LAN91C113,the driver I used is smc91111.c. I've defined CONFIG_DRIVER_SMC91111,undefined xxx_USE_32_BIT undefined xxxx_EXT_PHY. When u-boot runs up, I try to ping my host from u-boot,but the sniffer on my host cannot catch any hardware packet,but my host sends ARP REPLY packet to my board. and the sended packet is captured by sniffer.Unfortunitly,board does'nt seem to have received right packet.I've enabled ET_DEBUG,It prints: RCV: STATUS 42 LENGTH 8. AND LEDA & LEDB both lights! What is the reason? Can you give me some ideas? Thanks a lot! Ricky
