[U-Boot-Users] Command line parsing question
by Jeff Angielski 12 Mar '04

12 Mar '04

u-boot-1.0.0/MPC8260 custom board When I type in commands at the command prompt and hit enter, some of the commands are getting run twice. For instance, version gets run twice while an md runs only once. => version version U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) => U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) => md 0x0 1 md 0x0 1 00000000: ff000000 .... => One thing to note about my setup is that I am accessing the serial console using telnet over a remote serial devices server. So the whole telnet end-of-line issue and the processing of CR,LF, and NUL come into play. Snooping the network and watching the character counts on the seriver server's serial port, I can see that each time I hit <Enter> there are two characters going over the serial line (CR-LF or CR-NUL) to the target. My questions are: 1) Has anybody else encountered this problem? I already googled for an answer but came up with nothing. 2) Does anybody have any idea why some commands are working and others are not? I would expect that either all would be repeated or none of them would be repeated. Thanks, Jeff

If you want to use a SRAM based version, you will probably have to modify U-Boot for it (except your board has jumpers to swap SRAM and flash in the memory map).

I just had the same problem today. In our case, turning off CR/LF and only sending ^M helped. As to why only some commands get run twice: The longer commands stops the serial port polling long enough that uboot drops the the LF after getting the CR. The shorter ones finish faster, and the last character gets interpreted as a nev return. > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net > [mailto:u-boot-users-admin@lists.sourceforge.net] On Behalf > Of Jeff Angielski > Sent: Thursday, March 11, 2004 17:41 > To: u-boot-users > Subject: [U-Boot-Users] Command line parsing question > > > > u-boot-1.0.0/MPC8260 custom board > > When I type in commands at the command prompt and hit enter, > some of the commands are getting run twice. > > For instance, version gets run twice while an md runs only once. > > => version > version > > U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) > => > > U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) > => md 0x0 1 > md 0x0 1 > 00000000: ff000000 .... > => > > One thing to note about my setup is that I am accessing the > serial console using telnet over a remote serial devices > server.

RE: [U-Boot-Users] [PATCH] New ADS GraphicsClient+ board port
by Kerl, John 12 Mar '04

12 Mar '04

Our brand-new board has flash byte-swapped. When we respin (we only made 5 in the first batch) we'll fix it. But for now, it's backward. And it turns out (so far) that there are minimal changes in the CFI code, which could be #ifdef'ed. Actually I'm using a strataflash.c from another board, but I don't think that matters too much -- it's still CFI-driven. -----Original Message----- From: u-boot-users-admin(a)lists.sourceforge.net [mailto:u-boot-users-admin@lists.sourceforge.net] Sent: Thursday, March 11, 2004 5:01 PM To: George G.

I am using the CFI driver on a BE system but I have the LE option defined since my flash is byte swapped. So that works for me, but I have to override the _LITTLE_ENDIAN define in just that file. So I think it should somehow look for a different define to override how it works. IE something like CONFIG_FLASH_CFI_BYTE_SWAP or something. Comments?

George,Wolfgang, Well done. I modified my configuration file to enable CONFIG_CMDLINE_TAG and I can now pass command line arguments to the kernel. Yipee!! I also checked the location of the BOOT_PARAMS phys addr and they were the same at 0x30000100. I've also noticed that the error I was reporting earlier in the week : "Warning: bad configuration page, trying to continue" has DISAPPEARED. All this excitement in one day!! One thing (there's always one more) ... does U-boot support writing to Intel Strata Flash? Thanks again, Dave "George G.

[U-Boot-Users] Newbie needs help with RAMDISK
by Luke Fimmerzane 10 Mar '04

10 Mar '04

Hi, I'm new to u-boot and would like to mount my rootfile system on a RAM disk. Its an arm 9 target. I'm using a book from KARIM YAGHMOUR called Building Embedded Linux systems as a reference guide to help with creating the RAM disk and understand the features of u-boot. (There's a really good section on u-boot in this book). I've managed to create the ramdisk, download it to my target but when I boot I get this message (only relevant sections included): Kernel command line: root=/dev/ram ...... ...... RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize ...... ..... cramfs: wrong magic FAT: bogus logical sector size 65535 Kernel panic: VFS: Unable to mount root fs on 01:00 AAgh!!! Where could I have gone wrong!! I know this is a voluntary site but if someone could give me some give me a few hints then thanks.

[U-Boot-Users] Memory Caching in Interrupt mode
by Sharad Gupta 10 Mar '04

10 Mar '04

Hi All, I am using UBoot as a firmware and boot loader for a custom development board based on MPC7455. I understand UBoot is not intended for use in interrupt modes, but I thought it does no harm in outputting some text on serial console everytime an interrupt comes in, say a timer interrupt (every 1 sec). I am using BDI2000 to start debugging at 0x900. But my problem is that since address translation is turned off while processing interrupts, I am not able to write to the serial port address since processor caches it and does not really push it out to the serial port. I am using ns16550 driver and the serial port is at 0x60000000. Whats the work around for this problem ? 1. Shall I turn the address translation on, but I am not sure if its safe to do that, and even if I do that where exactly should I do that, in timer_interrupt routine or transfer_to_handler routine ? 2. Or shall i disable the data caches while processing interrupts ? Thanks Sharad.

Could you mask the following code in YOUR_BOARD.h? /* #define CONFIG_CLOCKS_IN_MHZ 1 ** clocks passsed to Linux in MHz */ For 2.4.x kernel,LINUX use Hz as the system frequency unit instead of MHz.

[U-Boot-Users] Problem booting MontaVista 3.0 Linux on IBM 405EP Bubinga board
by Andy Vo 09 Mar '04

09 Mar '04

Hello all, I am using U-boot with Linux version 2.4.18 but booting hung at = "Uncompressing Kernel Image...OK".=20 I modified the bd_info structure in the kernel (file = include/asm-ppc/ppcboot.h) to match the bd_info structure of U-boot = (file include/asm/uboot.h) as suggested in the U-boot manual.

[U-Boot-Users] u-boot on a quad processor board
by Frank 09 Mar '04

09 Mar '04

I have u-boot running concurrently on all 4 processors on our multi-processor board. Anyone interested in this. If so I will clean up my code and submit a patch. Also, my next task is to keep u-boot in flash (with a limited number of commands) if the sdram fails. This is will allow the user to peek and poke from the command line to configure the sdram controller or debug sdram so it (u-boot) can complete the booting process to sdram. This the only short coming I can see that u-boot has.:-) __________________________________ Do you Yahoo!? Yahoo! Search - Find what you�re looking for faster http://search.yahoo.com

I have a bunch of sc520 fixes from a board port I did. This one is cause by a bad linker directive file (u-boot.lds). I believe I fixed the other sc520's also. I need to check and submit a patch. My board has a 512k 8-bit flash - you will have to adjust the flash address in the linker file and in the 16 bit .S if your flash is larger. -brad /* * (C) Copyright 2002 * Daniel Engström, Omicron Ceti AB, daniel(a)omicron.se. * * See file CREDITS for list of people who contributed to this * project. * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License as * published by the Free Software Foundation; either version 2 of * the License, or (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[U-Boot-Users] Warning: bad configuration
by asnua＠eircom.net 08 Mar '04

08 Mar '04

Hi, I finally managed to boot my S3c2410 ARM board using u-boot. However, all is not plain sailing. Problem 1: I've noticed that whenever I set up the environment variable 'bootargs' its value is never passed to the kernel. I can now only change the kernel command line by using make menuconfig for the kernel and changing the default command line in the kernel but this means I have to keep re-compiling the kernel if I want to have a different kernel command line! Problem 2: I've also noticed that I get a 'Warning: bad configuration page, trying to continue' message which I've read is to do with the kernel expecting a tagged list of parameters from the bootloader but the bootloader is not setting it up where the kernel expects it. Can someone answer the following: (1) Does u-boot use param_struct or kernel tagged list. Or does it convert the old style param_struct to a tagged list? (2) What can I do to get the kernel to 'see' the 'bootargs' env variable. Many thanks for your help, Dave Attached : o/p from board on boot up SMDK2410 # bootm ## Booting image at 33000000 ...

[U-Boot-Users] IDE and SCSI devices in U-Boot
by sudhakar rajashekhara 08 Mar '04

08 Mar '04

Hi All, We have ported U-Boot and Linux-2.4.22 onto a custom powerpc board. We have a Serial ATA card (SATA150 Tx2plus) sitting on PCI, which supports 2 devices. A Hard Disk has been connected to one of the port of the Serial ATA card. Linux identifies this Hard Disk as a SCSI device and configures it properly. Now I want to boot Linux from the the Hard Disk using U-boot. Can I configure the Hard Disk as an IDE device from U-boot or do I have to configure it as a SCSI device? Thanks in advance, regards, Sudhakar. __________________________________ Do you Yahoo!? Yahoo! Search - Find what you�re looking for faster http://search.yahoo.com

[U-Boot-Users] Installation of ELDK 2.1.0 for MPC8xx,
by RamanaYV 08 Mar '04

08 Mar '04

I was installing ELDK-2.1.0 in my host ( kernel 2.4.20-8, Red Hat Linux Release 9.0). I was facing the following problem,while following the steps given in "The DENX U-Boot and Linux Guide (DULG) forTQM8xxL" document. Initially i run install utility,it worked fine. Then i tried to install the rpm of ELDT :binutils-ppc_8xx-2.11.93.0.2-3b_2, it is showing like libc.so.6(GLIBC-2.0) libc.so.6(GLIBC-2.1) libc.so.6(GLIBC-2.1.3) libc.so.6(GLIBC-2.2.3) libc.so.2(GLIBC-2.0) libc.so.2(GLIBC-2.0) is needed by binutils-ppc_8xx-2.11.93.0.2-3b_2. i will be very much thankful,if any one help in this regard. Thank u Ramana

[U-Boot-Users] PPC405GPr reset troubles
by Stephen Williams 07 Mar '04

07 Mar '04

This may be slightly off-topic, but the hardware is as right as I can get it, so I'm looking for some sort of software problem. I am having trouble with the "reset" command, and the /SysReset in particular, in connection with the EBC clock settings. The PSR (Pin Strapping Register) is spontaneously changing values on the /SysReset. In particular, the external bus clock divisor is changing from /4 to /2. I've added a dump of the PSR right where U-Boot prints the CPU speeds, and I get the following: U-Boot 1.0.2 (Mar 5 2004 - 17:03:00) XXXX PSR=0xfdfc0ce0 CPU: IBM PowerPC 405GPr Rev. B at 266.500 MHz (PLB=133, OPB=33, EBC=33 MHz) PCI sync clock at 33 MHz, internal PCI arbiter enabled 16 kB I-Cache 16 kB D-Cache [...etc...] ñ> reset U-Boot 1.0.2 (Mar 5 2004 - 17:03:00) XXXX PSR=0xfdf80ce0 CPU: IBM PowerPC 405GPr Rev. B at 266.500 MHz (PLB=133, OPB=33, EBC=66 MHz) PCI sync clock at 33 MHz, internal PCI arbiter enabled 16 kB I-Cache 16 kB D-Cache I see with an O'Scope that the EMCTxEN signal (which is the difference between PSR values) is really low during the /SysReset, and it is clearly stable low then. But the PSR is read-only? Why is my PSR wrong? -- Steve Williams "The woods are lovely, dark and deep. steve at XXXXXXXXXX But I have promises to keep, http://www.XXXXXXXXXX and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep."
