[U-Boot-Users] Ethernet on PPC Ebony not working
by Srikanth Sherman 20 Nov '03

20 Nov '03

Hello, I got u-boot 0.4.0 up and running on the Ebony PPC440GP development board. Everything works great except for the Ethernet. The link light in ON, but I can't seem to ping out (which, after searching the list, it seems at least one other person also couldn't ping) or download any code (TFTP) onto the board through the Ethernet. I ran Ethereal and didn't even see any ARP packets from the board. I know my setup is OK because if I switch to the IBM Monitor program then I can use the Ethernet without any problem. Any help would be greatly appreciated. Thanks!

Be VERY careful when lighting LEDs during start up -- a big part of the start up, and definitely the most delicate (i.e. highest probability of problems), is the transition from "no MMU" mode to MMU mode. During this time, your I/O quite likely won't be mapped or won't be mapped properly unless you hack in some additional MMU mapping (BATs). The result, if you are not careful, is that the attempt to toggle LED outputs will CAUSE a crash and will cause a lot of confusion, head-scratching, and chasing down wrong paths. Umm, someone I know did this... yeah, that's the ticket ;-). gvb > Thanks for helping, > Sharad Gupta ****************************************** The information contained in, or attached to, this e-mail, may contain confidential information and is intended solely for the use of the individual or entity to whom they are addressed and may be subject to legal privilege.

RE: [U-Boot-Users] u-boot and NIOS dk 1s10 board
by Scott McNutt 19 Nov '03

Hi All, I agree with all of the comments I have seen so far WRT Nios configuration issues. My primary motivation is to make sure Nios users new to u-boot, can build a __working__ version of u-boot by simply: $ make DK1C20_config | DK1S10_config | etc. $ make As long as this holds true, I'm happy :-) > Yes, of course. We have to make different configuration > files -- one for each board. But, do we really need different > board directories with almost the same code in it? u-boot has a clever mechanism we can use to avoid code duplication by using the VENDOR make variable. A good example is in board/siemens: the SCM and CCM boards both share common code. Since this mechanism is supported ... and it is being used by other board families, we can do the same. It's a bit more work ... but I believe it will satisfy everyone :-) > Ex.: My current Stratix patch is based on the Cyclone board, > because both boards are equal in context of u-boot basics need. > Only the second serial i/f differs (not needed til now). So there > will be more identicalness than differences for both boards. Understood. We can create board/altera_nios (or some other meaningful name) and take advantage of the VENDOR variable to accommodate common code. Stephen & Patrice, please let me know your thoughts.

[U-Boot-Users] Boot from Compact Flash
by Ed Okerson 19 Nov '03

19 Nov '03

My BDI2000 is due to arrive today, I'm just waiting for FedEx to show up. In the meantime, I managed to get u-boot to run from RAM, so I wanted to get a head start on booting from Compact Flash. I have a 256MB CF card in a PCMCIA adapter. When I insert this in a Linux Laptop, it properly reports it as a SanDisk 256MB CF card. I managed to get u-boot to build Little Endian, and in that mode when I insert the PCMCIA it reports it as: Reset IDE: Bus 0: OK Device 0: Model: aSDnsi kDSFC-B52 6 Firm: dV g.812. Ser#: 1144901E09P30101 Type: Removable Hard Disk Capacity: 117964.8 MB = 115.2 GB (-1476395001 x 512) Obviousle the endian-ness is wrong. I tracked to the code in common/cmd_ide.c where there is a note: /* We only need to swap data if we are running on a big endian cpu. */ /* But Au1x00 cpu:s already swaps data in big endian mode! */ #if defined(__LITTLE_ENDIAN) || defined(CONFIG_AU1X00) #define input_swap_data(x,y,z) input_data(x,y,z) Where is the bit getting set that tells the Au1500 to swap bytes? If I build u-boot as big endian, it properly recognizes the CF card. I am using the BdAu1500 board. Is there a discussion somewhere about the pros/cons of running in big/little endian mode?

[U-Boot-Users] Question about setting the sys clk freq based on a pull up on io.
by Conn Clark 19 Nov '03

19 Nov '03

Hello all, We have just finished designing the cpu to our next generation product and I'm just getting into the U-boot code. In my preliminary examination of our design and U-Boot I ran into an interesting problem and wanted to see if anybody had a solution or suggestion on an approach. Our design is based on a 333MHz IBM405EP processor. We wish to detect the oscilator speed we are using via a pullup or pulldown resistor on an IO line. In order to make our product cheap we were planning to drive the system clock with a 25MHz oscilator that also drives our ethernet phys. We wanted the flexibility to use a second oscilator to drive the system clock at 33.3MHz so we could have the option of driving our processor, RAM, and PCI bus at the maximum speed. to do this we added a second set of pads for an oscilator inbetween the 25MHz oscilator and the mcroprocessor, so we only need to cut the trace between the two oscilators when we wish to use the 33.3MHz clock. What I was planning to do was initialy configure a microprocessor IO pin as an input and read the value of the pull up or pull down to determine the system clock speed then reconfigure it as an output to be used as a control line. My problem is how do I go about this without severly modifying U-Boots structure. In analyzing how to do this I determined that the configuration and reading of the IO pin sould be done in a board_pre_init function. This rases the issue of passing values between the init functions called by board_init_f. My second issue is how do I deal with the two frquencies since only one can be defined as CONFIG_SYS_CLK_FREQ(which is used in several places) without sticking lots of nasty board specific ifdefs through out the code. I didn't see a solution in any of the other boards that I looked at (Note I didn't look at them all). We realy don't want to have to specify at compile time what frequency we intend on using. This may become an option on our products and we don't want to have two different firmware images to confuse our costomers (and ourselves). This causes to many headaches with determining what the costomer has and problems created by loading the wrong firmware. Has anybody tackled these two problems yet or do they have any sugestions?

[U-Boot-Users] U-Boot success .. Linux big test
by Sharad Gupta 19 Nov '03

19 Nov '03

Hi, I have been able to port U-Boot to our bare minimum custom board based on MPC7455. With RS-232 the only peripheral to speak of, it was not a hard job porting the U-Boot. I am able to run the example hello_world demo. I had to change some cpu specific code at 1-2 places, I will like to submit the patches as soon as I get a breather. But now the big test for me is to run kernel on top of U-Boot. Looking at u-boot README, I compared the u-boot.h file with linux's include/asm/ppcboot.h. The only difference is the member bi_mon_func. I am not able to find out if I have to replicate the same structure of monitor functions in U-Boot to be passed to kernel on boot or is it handled elsewhere ? Rite now, I am not able to figure out where the problem lies, the execution hangs somewhere after handling the control to kernel at 0x00 and it seems my only hope is to put little debug messages (light up the 4 LEDs on board with the last 2-bytes of instruction address) at every function call. Thanks for helping, Sharad Gupta

I enthusiastically agree :-) It is not simply a good idea, but IMHO *essential* that each Nios board have it's own u-boot configuration. Since *everything* is configurable with Nios, it's very easy to create a monster by having multiple board configs masquerading as one. U-Boot for Nios development kits should always support the default "out-of-the-box" Nios configuration (for the altera boards, this is typically the "standard 32" config). This is not intended to limit creativity, but to avoid confusion and save time. Basically, if new users get u-boot running quickly and easily, maintainers and contributors will spend less time answering questions. And this is a good thing for both the user and contributors :-) In general, support for custom configurations should be: 1. disabled by default, 2. enabled IAW README (i.e. CONFIG_xxx CFG_xxx), 3. supported by an appropriate README file in u-boot/doc. Congratulations & Best Regards, --Scott N3ADP

[U-Boot-Users] 855T FEC error

Dear all, We have u-boot (1.0.0) running on our custom board :) Our board uses 855T and LXT972A. Trying to do: ACM=> bootp Trying FEC ETHERNET PHY type 0x13 pass 1 type PHY @ 0x0 pass 1 type LXT971 BOOTP broadcast 1 TX timeout fec.c[134] fec_send: cycles: 100 status: 8c00 retry cnt: 0 With a login analyzer we can see that after some time the TX_ER is raised and TX_EN not. The PHY seem to work OK. The LED's light correctly and we can see the 25MHz TX and TX MII clocks. Reading the registers with u-boot's mii read, the registers are the same as the TQM860L. We use the same configuration as TQM855L.h, but we add - CONFIG_8xx_GCLK_FREQ 50000000. I don't think its related to this problem, but we cannot save the u-boot environment. It is saved to the flash at 4000c000 but does not appear after reset following printenv. I didn't have time to look into this issue yes. Last but not least, I wish to thank you all, the information in this list helped us very much. Any suggestions ? Thank you, Eli Brin

Hi Stephan, It works now...in fact, my reference design for STRATIX configuration was not similar to the IO mapping used by u-boot for NIOS... It works with the Altera's "standard 32" reference design (with the .SREC in the CDKNIOS project and after u-boot recompilation too). I'll write a little doc on the IO and memory mapping to respect in order to used u-boot... My student will work on the u-boot APEX port...just an adaptation I think... I may be a good idea that the stratix 1S10 board appears as its own board and not as a cyclone board in the u-boot distro... My next step is to see is the standard 32 reference design is OK for uClinux support in order to freeze the hardware.... Many thanks; Pat Stephan Linz wrote: >Am Freitag, 14.

[U-Boot-Users] 8270 graphics
by Marco Schramel 17 Nov '03

17 Nov '03

Hi, for a new project, we are planing to introduce the new PowerPC 8270 with a display. The graphic controllers we are interested in are the SM712 or the SM722 with their PCI interface. An another cheaper alternative could be the EPSON SD13xx series (U-Boot can initialize this controllers). But on the EPSON homepage it is metioned, that this controllers are only compatible with the 8xx PowerPC's.(The epson support says: "if the external interface is the same as in the 860, you should be able", What do you think about it ?) Have anyone experience with the 82xx and one of this graphic controllers? Are there working linux device drivers for it? Are there other low cost and low power graphic controllers for this cpu ?? Thanks in advance Marco Schramel

[U-Boot-Users] Linux for the MPC5200...

I see that the Motorola 5200Lite eval board has been added to u-boot and that DENX is providing a Linux kernel for the MPC5200. What bits are required to get to the next step? I am very interested in the IDE port on the 5200Lite. Is it supported? Would a full 603e Linux (Yellowdog?) work once the 5200 kernel was up? What I would really like is to get the 5200lite up as a full, self-hosted, PowerPC Linux development system.

[U-Boot-Users] Porting u-boot to custom MPC852T board.
by DavidHo＠nanometrics.ca 15 Nov '03

15 Nov '03

Hi, I'm currently porting u-boot version 0.4.8 to our custom board running an MPC852T. The processor is configured to high-boot at 0xfff00000. U-boot is failing to execute any instructions in RAM after it has been relocated. I did a CRC check on the code in RAM and compared that to the code in flash. I compared the memory dump of in_ram in RAM (which is the first thing u-boot jumps to in RAM) and the same routine in flash. They match exactly. Nothing seems to indicate that I have a problem writing and reading to the SDRAM at these locations. Stepping through relocate_code gave me the expected results. I then put a breakpoint at the branch location in RAM and tried tracing the instructions there, but none of it made any sense to me. I am pretty sure relocate_code is branching to the right location in RAM. This looks like a caching problem because it seems like it is not fetching the instructions from memory. Does anyone have a similar problem with MPC866 family of processors? The code in ram just execute from address in_ram to in_ram+0x98 and branches back to in_ram in an endless loop. Does it appear to look like some section of code that was previously ran from flash but was remain in cache? This portion of code modifies R3 to fff2dc00 which is definitely wrong because in_ram tries to do a store to that location, which it is the high boot flash memory region.

No, currently only the Cyclone development board is supported. But based on the information I've received, the Stratix board is very similar ... so adding support should be fairly straight forward. > Is anyone try to port µClinux on NIOS ? I'm currently working > on this point and having a linux bootloader is the first step... Yes ...you can view the Nios sources for uClinux archive at: http://cvs.uclinux.org/cgi-bin/cvsweb/uClinux-2.4.x/arch/niosnommu/ I haven't had a chance to work with uClinux yet ... as I'm currently working on support for Nios ASMI ... which is only useful for Cyclone devices. But please do keep me in the loop ... I'd love to help ... once I find some time :-) Regards, --Scott

[U-Boot-Users] Passing Linux kernel arguments
by Matias Sundman (AL/EAB) 14 Nov '03

14 Nov '03

Hello, When passing Kernel arguments, is it necassary to populate the bootargs environment variable with the information found by using command , 5.9.1.1. bdinfo - print Board Info structure => help bdinfo bdinfo - No help available. => The bdinfo command (short: bdi) prints the information that U-Boot passes information about the board like memory addresses and sizes, clock frequencies, MAC address etc. This information is mainly needed to be passed to the Linux kernel. => bdi memstart = 0x00000000 memsize = 0x04000000 flashstart = 0x40000000 flashsize = 0x00800000 flashoffset = 0x00030000 sramstart = 0x00000000 sramsize = 0x00000000 immr_base = 0xFFF00000 bootflags = 0x00000001 intfreq = 50 MHz busfreq = 50 MHz ethaddr = 00:D0:93:00:28:81 IP addr = 10.0.0.99 baudrate = 115200 bps If I want these to be passed to the Linux kernel?

RE: [U-Boot-Users] what is wrong when calloc return bogus?

You say loading.....are you starting from flash, then relocating to the middle or RAM _or_ are you using something to download a binary image into the middle of memory, then trying to execute it? There aren't that many files to configure, it should be straight forward to find. JTAG is a wonderful thing, you should take the time to get it working...assuming your hardware has wired it up correctly. Regards, Richard W. > -----Original Message----- > From: Matthew S.

U-boot 1.0.0 and before for the last ... ?Six months has had an OMAP tree. Its really trivial to port from that to a new target. There is a omap1510inn target which is the Innovator. I have a couple tress which I've not yet merged in for custom boards which have a lot more functionality, but we will do that at some point, probably closer to the time they actually go into production. Cpu/arm925 is for the arm core on the OMAP15xx. I've sprinkled enough code in to idle the dsp but not much beyond that. The is a 926 tree also, that is for the omap 16xx. The CPU core is common in a lot of different SOC's, that's what the CPU was broke out separately. It could have been done differently, but the hope is to allow sharing of common code bits, not duplicate them. It seems you must be using an older tree as this kind of thing is sort of hard to miss if you have gone though the code. Regards, Richard W. > -----Original Message----- > From: Matthew S.

-- The PXA default setup low/high is such that with out a patch the PXA will fail. The PXA attempted to follow the readme instead of just doing what the other ARMs did successfully. -- If you cloned the ARM925 tree, then you should NOT see this failure. Its probably some other kind of misconfiguration. -- For my OMAP board I setup up so u-boot is copied to the start of the last meg of memory. Everything has always worked properly. !**! Your problem is likely you setup your u-boot to reside in at the exact end of memory, this won't work as the stack and heap are allocated on top of the text image. You will be doomed to failure. Move your load address down a bit and it WILL WORK. -- Just as a double check I setup a hardware break point at NewHandle on my board, and sure enough the address was "exactly" where I expected it to be in the malloc region. -- There are merits to switching the memory map so the malloc and stack regions are below the text image. In my opinion the only compelling reason to make the switch is because Wolfgang has committed to moving it, so it will be more work to keep a special version around. I only am resisting the change as I made a several "pretty" and time consuming diagrams which I don't want to re-do :) Regards, Richard W. > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net > [mailto:u-boot-users-admin@lists.sourceforge.net] On Behalf > Of Matthew S.

[U-Boot-Users] Porting Linux into PPC750
by a b 13 Nov '03

13 Nov '03

hi, Have any one ported Linux into IBM PowerPC PPC750 based embedded boards.. Has anyone developed the u-boot for PPC750 based board. If anyone has done it.. please pass on the information to me... I have been struggling with it. The PCI bridge that I am using is IBM CPC700. Regards, Deepu __________________________________ Do you Yahoo!? Protect your identity with Yahoo!

[U-Boot-Users] U-Boot hang
by Leon KUKOVEC 13 Nov '03

13 Nov '03

Hi everybody, I'm in the process of writting PCMCIA support for WEPEP250 (boards/wepep250). Everything seems to be going smooth except one thing: When I add a debug function and then execute U-Boot command "pinit on" or "ide reset" U-boot hangs on me. I sometimes get "data abort", sometimes "invalid instruction" and sometimes nothing. Is there any limits with regards to U-Boot's size and by me putting too much inside U-boot's .text section and hitting some marker/border ? The situation: ident_cpy() function used in ide_ident() copies firmware, version, ident string from iop structure to dev_desc structure. Since CompactFlash firmware string and model number string are in big endian byte order I wanted to write ident_swap_cpy, but as I wrote the function, re-compiled U-boot, downloaded it and issued "ide reset" I got a hang. I also tried to put just two printf's inside ident_copy() - a hang again. ident_swap_cpy() worked fine when I compiled and ran it in my examples/ide.c file. Thanks, -- Best Regards, Leon.
