[U-Boot-Users] Question on do_bootm in cmd_bootm.c
by Nick Barendt 31 Mar '05

31 Mar '05

Can someone, maybe Wolfgang, comment on the maximum 4MB uncompressed size of gunzip (and, possibly, bzip2) images? I've been working on a Coldfire 5272 system for quite some time with u-boot and uClinux. Both have been remarkably stable. We use the uClinux default build wherein the root filesystem (romfs) is appended to the end of the kernel image, starting where the bss would normally be. The kernel startup code relocates the romfs image to just beyond the bss, then, and everything runs smoothly. I know that many folks in the PPC world use separate kernel and root filesystem images, for many good reasons, but many (most?) of the uClinux platforms use this concatenated kernel+romfs image. Recently, we've been adding more content to the root filesystem. As our root filesystem grew larger (say about 3MB), however, we started seeing boot problems where the kernel would boot fine but the root filesystem was clearly corrupt. I've spent the better part of two days trying to track down where things go wrong, from the kernel to u-boot. Of course, I used a hardware debugger, looked at u-boot's memory assignments, image load addresses, entry points, malloc areas, etc. I just located the source of my trouble, a hard-coded 4MB maximum uncompressed size in do_bootm: int do_bootm (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) { ulong iflag; ulong addr; ulong data, len, checksum; ulong *len_ptr; uint unc_len = 0x400000; ^^^^^^^^^ int i, verify; SNIP case IH_COMP_GZIP: printf (" Uncompressing %s ... ", name); if (gunzip ((void *)ntohl(hdr->ih_load), unc_len, ^^^^^^^^ (uchar *)data, (int *)&len) != 0) { printf ("GUNZIP ERROR - must RESET board to recover\n"); SHOW_BOOT_PROGRESS (-6); do_reset (cmdtp, flag, argc, argv); } break; SNIP Increasing unc_len to larger values (like 6MB) seems to solve my problem. With an uncompressed image larger than 4MB, gunzip doesn't seem to generate any errors (granted, I haven't stepped through gunzip and zlib), but merrily runs along, although the data beyond the 4MB boundary seems to be missing or corrupt. It looks like there's a truncation (about line 1875 in zlib.c) to z.avail_out in zlib that prevents data from being copied beyond unc_len - maybe that should be an error instead of silently truncating data? Just a thought. I'll into submitting a patch for that. I was wondering if there was some reason for the 0x400000 magic number for unc_len. Is that just a magic number? Is that larger than anyone uses for images? I guess I'm a little surprised that this hasn't bitten anyone else so far (nothing I could see on the mailing list archive, at least). Our 1MB kernel and 3MB romfs root filesystem might be exceptionally large, I don't know. Would there be any issues with making unc_len a CFG_ macro, if I submitted a patch? Nick Barendt

[U-Boot-Users] Make drivers/cfi_flash.c protect environment and redundant enviro nment
by Michael Bendzick 26 Feb '05

26 Feb '05

Included is a patch to the drivers/cfi_flash.c driver that will automatically enable environment and redundant environment protection protection upon booting. Previously, only the monitor (U-Boot) was protected by the driver.

[U-Boot-Users] Environment in flash rather than EEProm
by Andy Hawkins 11 Feb '05

11 Feb '05

Hi all I'm using a PPChameleonEVB, and am trying to move the u-boot environment into flash. I've modified the include/configs/PPChameleon.h file as follows: #define CFG_ENV_IS_IN_FLASH 1 #define CFG_ENV_ADDR 0xFFFFA000 #define CFG_ENV_OFFSET (CFG_ENV_ADDR - 0xFFFC0000) #define CFG_ENV_SIZE 0x2000 I've added some debugging into the section where it reads the environment, and I'm seeing the following: U-Boot 1.0.2-adh-2004/03/29 (Mar 30 2004 - 13:40:38) CPU: IBM PowerPC 405EP Rev.

Shouldn't this be 0xFFFFA000? Is there anything else I need to do to force the location of the environment into the required place? It looks like the address of the environment is based on the location of the 'environment' variable in common/environment.c. Do I need to change the LD script to force this variable to a certain location? If so, can anyone help with what I need to do (I'm not familiar with LD scripts yet). Many thanks. Andy

Shawn, > One issue I've encoutered is flash write timeout of a big > chunk of data (> 128KB). Write always times out no matter how > big the value of CFG_FLASH_WRITE_TOUT is. The issue hasn't > been solved yet. Any hints are appreciated. I have tried with removing the test for timeout in the write_data() routine, just looping on the status: while (((status = *addr) & (FPW) 0x00800080) != (FPW) 0x00800080) ; This worked fine for large amounts of data so the timeout value is probably too low. Let me know if this is the same with your setting. Regards, Philippe

[U-Boot-Users] Stand alone app for changing MAC address in SMC91C111

I have created a stand alone application to change MAC addresses in the EEPROM attached to the SMC91C111, as well as the following commands: - P : Print the MAC address in the EEROM and MAC - D : Dump the LAN91C111 EEPROM contents - M : Dump the LAN91C111 MAC contents - C : Copies the MAC address from the EEPROM to the LAN91C111 - W : Write a register in the EEPROM or in the MAC It can be reviewed at our u-boot (based on 1.1.1) cvs for the Blackfin BF533 processor at: [sorry for the long url, but what can you do?] http://cvs.blackfin.uclinux.org/cgi-bin/cvsweb.cgi/u-boot_1.1.1/examples/?c… added: smc91111_eeprom.c README.smc91111_eeprom Based on people's feedback, I will submit as a patch to this list.
