[U-Boot-Users] [PATCH] Support dynamic/patched NAND ENV offset
by Harald Welte 17 Feb '07

17 Feb '07

This patch adds support for CFG_ENV_OFFSET_PATCHED and CFG_ENV_OFFSET_OOB. Both try to solve the problem of fixing the environment location in NAND flash at compile time, which doesn't work well if the NAND flash has a bad block at exactly that location. CFG_ENV_OFFSET_PATCHED puts the environment in a global variable. You can then use the linker script to put that variable to a fixed location in the u-boot image. Then you can use bianry patching during the production flash process. The idea of CFG_ENV_OFFSET_OOB is to store the environment offset in the NAND OOB data of block 0. We can do this in case the vendor makes a guarantee that block 0 never is a factory-default bad block.

[U-Boot-Users] u-boot 1.1.6 for atmel at91rm9200
by Matt Gessner 16 Feb '07

16 Feb '07

Hi, All, I'm finding some problems that appear to be serious errors in the 1.1.6 release for the Atmel AT91RM9200. I've passed some of these on to Wolfgang Denk, but I surmise he's simply too busy to respond to single messages, and I certainly understand that. So, I'll pass on what I've found, and anyone who wants to confirm or discuss these is certainly welcome to do so. a) The Ethernet driver sets up PB19 for RMII mode. See cpu/arm920t/at91rm9200/ether.c and look for eth_init. You'll see that if CONFIG_AT91C_USE_RMII is defined, then PB19 is to be used. The problem is that PB19 is an MII pin, not an RMII pin, as can be confirmed with the -dk and -ek schematics. Once I removed this, and just did #ifndef CONFIG_AT91C_USE_RMII // all the stuff to configure PB19 -> PB12 for MII mode #endif Then everything worked fine. b) The cp.b wasn't working for copying from SDRAM to DataFlash because the code to decide whether to copy to flash was broken, because it was passing addr to addr_dataflash and not dest. e.g. the code was this: if ((addr2info(dest)!= NULL) && (!addr_dataflash(addr))) when it should be (AFAIK) if ((addr2info (addr) != NULL) && (!addr_dataflash(dest)) this part then copies to the regular flash. c) There are inconsistencies in the PLLAR_VAL being used. In the manual it states that the OUTA bits in the PLLA config register should be "10" if the output frequency is to be between 150 and 240 MHz, and 00 when the output frequency is to be between 80 to 160 MHz. So the value that should be put in this register for full speed operation would have OUTA = "10" not "00" as it is in the file. This is in include/configs/at91rm9200dk.h. I'd like to hear people's comments on this. Thanks in advance, Regards, Matt Gessner

[U-Boot-Users] Environment is in OneNand ?
by pradeep sawlani 16 Feb '07

Hi all, I am using u-boot version 1.1.4 i am using custom board based on s3c2412. On my custom board, i don't have any nor or nand flash except onenand. While creating a configuration file for the board ,I was not able to find any way where i could say environment is in onenand(like for nand CFG_ENV_IS_IN_NAND) ? TIA, Regards, Pradeep.

[U-Boot-Users] ppc arch specific memcpy issue?
by Chris Morgan 16 Feb '07

16 Feb '07

Using uboot 1.1.6 compiled with a powerpc gcc 4.1.0 cross compiler on a mpc5200 board and booting from flash. If I disable architecture specific bcopy, memmove and memcpy via __HAVE_ARCH_BCOPY etc, I'm able to boot up properly, in this case into GHS Integrity. If I use the architecture specific asm versions of these functions I get "CheckSuccess" errors. Has anyone seen something similar? It appears as if the elf load doesn't do the same thing with the ppc optimized code but I would have thought someone would have noticed this sooner since lib_ppc/ppcstring.S appears to have been modified for quite some time now.

[U-Boot-Users] About interrupt processing on MIPS32 4Kc
by sai 16 Feb '07

16 Feb '07

I am using Broadcom BCM7401 platform of MIPS32 4Kc bases. This time, I decided to do u-boot porting. In the midst of analyze source code, found out to u-boot's code for MIPS32 4Kc that interrupt processing part does not exist. Why do not handle interrupt processing in u-boot of MIPS32 4Kc bases? Could not find exception vector processing part. relocate_code() exception vector thing which do relocation by memory be? Basically, do not you use interrupt in u-boot of MIPS32 4Kc bases? How do you treat devices(UART, Etherent,..) back differing without interrupt? Are you doing polling? I wonder very. -- *************************************** Yongdae, Shin *************************************** H.P : 017-268-4413 Office : 02-555-9200 (312) ***************************************

[U-Boot-Users] 0x40000 vs 0x40004
by Charles Krinke 16 Feb '07

16 Feb '07

I have a friend with a test program that used to be in ppcboot and is now moving to uboot. With some compilations on some computers he gets his /examples/hello_world starting at 0x40000 and on others it starts at 0x40004. The first 4 bytes appear to be a magic number which is either 0x18220 or 0x18300 depending on ppcboot or uboot and old or newer toolchain. The question is: "What file controls the addition (or deletion) of this 4 byte magic number at the beginning of "hello_world?" Charles
