[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?

After that I want to port U-Boot to a self-made Board wich is equiped with a MPC604, too. Best regards, Johannes

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.

Hi Does CONFIG_BOOTARGS and or CONFIG_CMDLINE_TAG have to be set before the env variable 'bootargs' gets passed to the kernel? Thanks, Dave

[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.
