I do not know, you need to ask U-boot-aware people. I've CCed some. > And why is the ubiformat not able to correct the problems? It should be able to format any flash. Probably this is a bug. Can you reproduce this with nandsim please? Just insmod nandsim on your PC (see http://www.linux-mtd.infradead.org/faq/nand.html#L_nand_nandsim or modinfo nandsim), write some garbage there or your image, and try to format it. If you can describe how I can reproduce this in my PC, I might look at this. Or you can just debug ubiformat yourself. -- Best Regards, Artem Bityutskiy (Артём Битюцкий)

Hi We are using AT91sam9261, till date we had never interfaced SDCARD in units . Now we need SDCARD interface in our units. for that i tried to compile u-boot i encountered problems, which are attached as MMC.log please get the attachement. and also we need mmc.h which is missing in u-boot path asm/arch/mmc.h This is the basic problem when I compile my u-boot version(u-boot-2008.10) for SDMMC CARD /u-boot-2008.10/u-boot-2008.10/include/configs/at91sam9261ek.h:157:1: warning: multi-line comment In file included from cmd_mmc.c:26: /u-boot_DFR3T/u-boot-2008.10/u-boot-2008.10/include/mmc.h:26:27: error: asm/arch/mmc.h: No such file or directory make[1]: *** [cmd_mmc.o] Error 1 make[1]: Leaving directory 'u-boot_DFR3T/u-boot-2008.10/u-boot-2008.10/common' make: *** [common/libcommon.a] Error 2 when i comment //#include <asm/arch/mmc.h> this section of code in "include/mmc.h" file, and try to compile i encountered the following problem. common/libcommon.a(cmd_mmc.o): In function `do_mmc': /u-boot-2008.10/u-boot-2008.10/common/cmd_mmc.c:35: undefined reference to `mmc_init' make: *** [u-boot] Error 1 -- Regards, RAJEEV RAO BATTU R&D Engineer, ANALOGICS TECH INDIA LTD.

[U-Boot] Is it necessary that uboot(mips) should read status register($12) before setting it
by RdrouterUboot Router 01 Oct '11

01 Oct '11

Hi all, MIPS Uboot works OK.Part of the code is as below. And my questions: 1.read status register($12) and save value to $10,but don't use the value in $10 to do anything. Because uboot overwrite $10. 2.Is it right?I can delete this code "mfc0 $10,$12" from uboot. Thanks. Bruce # Initialize Misc. Cop0 state # Read status register mfc0 $10, $12 //Can I delete this code? # Set up Status register: # Disable Coprocessor Usable bits # Turn off Reduce Power bit # Turn off reverse endian # Turn off BEV (use normal exception vectors) # Clear TS, SR, NMI bits # Clear Interrupt masks # Clear User Mode # Clear ERL # Set EXL # Clear Interrupt Enable # modify by Bruce #li $11, 0x0000ff02 li $11, 0x00000004 mtc0 $11, $12 # Disable watch exceptions mtc0 $0, $18 # Clear Watch Status bits li $11, 0x3 mtc0 $11, $19 # Clear WP bit to avoid watch exception upon user code entry # Clear IV bit - Interrupts go to general exception vector # Clear software interrupts mtc0 $0, $13 # Set KSeg0 to cacheable # Config.K0 mfc0 $10, $16 //Overwrite $10 register.Why uboot read status register($12) and save value to $10,but don't use $10. li $11, 0x7 not $11 and $10, $11 or $10, 0x3 mtc0 $10, $16
