[U-Boot-Users] netconsole facility in uboot
by Maximus 30 Jan '06

30 Jan '06

Hi, i understand netconsole facility is there for dumping messages to a remote conole via ethernet and to accept commands from remote console. But, how does one configure for netconsole. apart of setting the environmental variables. Suppose i want ONLY u-boot to listen to remote commands - how does one configure u-boot. I went through README.Netconsole. Thanks, Regards, Jo

[U-Boot-Users] board bring up, mpc8555 custom board
by Cam 28 Jan '06

28 Jan '06

Hi We have used u-boot-1.0 on our 8260 based boards with great success. We are trying to bring up a new mpc8555 based board with u-boot-1.1.4 but have run into some problems. We have a BDI probe which is used for programming flash and exercising hardware using JTAG. Using the BDI probe and a fairly extensive config file (which sets up TLBs and LAWBARs) we are able to step through the programmed u-boot although it has an alignment exception whilst running cpu/mpc85xx/start.S (at the part after the comment "Allocate Initial RAM in data cache"). We think it's an alignment exception because it jumps to the alignment exception handler address and continues briefly. The u-boot code is modified from the mpc8560ads code, the main difference being the boot flash is 32Mb and we have no localbus SDRAM. I have a suspicion that we shouldn't be trying to single step this initialisation code after the BDI has set up the hardware somewhat. I have tried a reduced BDI config file and it still doesn't work, and it no longer single steps. Any suggestions how to proceed would be appreciated, does the alignment exception after allocating RAM suggest anything to anyone? Thanks -Cam -- <-- camilo(a)mesias.co.uk

[U-Boot-Users] quesions in porting ARMBOOT to the CX821xx(ARM940T)
by dennis fu 28 Jan '06

28 Jan '06

Hi, all I have some questions in porting the ARMBOOT to the CX821xx(ARM940T). in the "start_armboot(void)": 1. when I skip two instructions and stop in one point, i.e. void start_armboot(void) { ... /* initialize environment */ //env_init(&bd); //skip it!!!! ... /* initialize environment */ //env_relocate(&bd); //skip it!!!! #if 1 //my code, stop here to get some debug information printf("I am here\n"); for(;;); #endif ... } My final BIN file is about 13kbytes, and the code works well (can printf all information). But, 2. when I open the two instructions, i.e. void start_armboot(void) { ... /* initialize environment */ env_init(&bd); //open it!!!! ... /* initialize environment */ env_relocate(&bd); //open it!!!! #if 1 //my code, stop here to get some debug information printf("I am here\n"); for(;;); #endif ... } My final BIN file is about 74kbytes, and the code is broken (no information output). I compare the relevant "armboot.map" files of these two case. The case 2 includes more functions than case 1. My question is: (1) why these two instructions affect in linking more functions? (2) I do believe I copy all code from the FLASH into the SDRAM before jumping the "start_armboot". Why I can run in the low part of code in the SDRAM, but when I call a function is far from the _START, my code is broken? The attackments are my two "armboot.map". Could somebody tell me something about my question? Because I new man in porting ARMBOOT, I really appreciate your help!

I noticed there's support for the KS8695 ARM based SOC. Anybody know where I can find a BDI2000 config. file for this device? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[U-Boot-Users] U-Boot stop booting after environment change + Environment in large nand flash
by Chun Kit Edwin Lau 27 Jan '06

27 Jan '06

Hi everyone, I have tried the large nand (2k erase size, K9F2G08U0M) code from testing-NAND. I can erase/read/write the NAND flash in U-Boot. I didn't try any ECC code, but things seems to be working out fine. I have modded the env_nand.c a bit to add support for environment in NAND for this chip. And it seemed ok. I have encountered two issues, on my custom AT91RM9200 board First, when I changed the default U-Boot environment in include/configs/at91rm9200dk.h. The resulting U-Boot didn't even boot. It only have the line "Uncompressing image" coming from boot.bin. And this problem was reproducible. And again, the default U-Boot environment was the only thing I changed. Is there a limit on the size of each environment variable? Did I overwrite some part of the program because the environment was too long? Second, I used fw_printenv to retrieve the U-Boot environment from Linux. (again, I modded it a little to use the large NAND) CRC didn't pass, but in U-Boot the CRC was ok. I uncommented the CRC checking in fw_printenv. And found out that one of the environment was corrupted. But the U-Boot didn't show the corruption. Any idea for the two incidents? Thanx Edwin

[U-Boot-Users] recieving network packets ?
by Maximus 27 Jan '06

27 Jan '06

Hi, I uboot - i want to recieve network packets. I wrote a small program using the code available in uboot. However its not working ?. Can anyone point me where i am going wrong ?. I am trying to write a server kind of a cmd - which recieves some requests from host and carries out some actions. I just want UdpProtoHandler to be called whenever the ethernet controller recieves a packet. As a start, i am sending raw ethernet packets on the network. But, NetReceive Function is not getting called. Why ?. Am i doing something wrong ?. Regards, John My Code, static void UdpProtoHandler (uchar * pkt, unsigned dest, unsigned src, unsigned len) ; static void udptimeout (void) { NetSetTimeout (100 * CFG_HZ, udptimeout) ; NetState = NETLOOP_CONTINUE; } int send_udp (void) { DECLARE_GLOBAL_DATA_PTR; eth_halt(); if (eth_init(bd) < 0) return(-1); NetState = NETLOOP_CONTINUE; NetSetTimeout (10 * CFG_HZ, udptimeout); NetSetHandler (UdpProtoHandler) ; return 1 ; } static void UdpProtoHandler (uchar * pkt, unsigned dest, unsigned src, unsigned len) { puts ("handler:-------------------\n") ; printf ("dest : %u src:%u and length : %u\n", dest, src, len) ; while (len > 0) { printf ("%c", *pkt) ; pkt++ ; len-- ; } puts ("\ndone\n") ; NetState = NETLOOP_SUCCESS; }

[U-Boot-Users] [PATCH] Add support for Freescale M5271 processor
by Zachary P. Landau 27 Jan '06

27 Jan '06

This change (and the two that will follow it) can be pulled from http://labxtechnologies.com/u-boot.git. This is in preparation for the next patch adds a new board that uses the 5271. Please let me know if this patch or the following ones need any work. CHANGELOG * Add support for Freescale M5271 processor Patch by Zachary Landau, 26 Jan 2006 Signed-off-by: Zachary P.

[U-Boot-Users] Accessing files on a fs in u-boot
by Kumar Gala 27 Jan '06

27 Jan '06

Are there any examples of how code in u-boot can access a file system. I see the code in common/ for the fs_load commands, wasn't sure if there were any other examples.. I'm being a little lazy and asking on list rather than poking through all the source :) - kumar
