Hi,
I managed to compile Barebox for AT91SAM9G20-EK, and I can run it. However
it seems not capable of reading the NAND Flash.
Output is at [1], my configuration is [2]. The "err -74" is EBADMSG, in
line 1057 of "file drivers/mtd/nand/nand_base.c"

Hi,

> Hi,

The ECC type used is NAND_ECC_HW, defined in file
arch/arm/boards/at91sam9260ek/init.c. I program the NAND using USB and
SAM-BA. I did not find a setting in SAM-BA to change the ECC type.
Changing the ECC to NAND_ECC_NONE in the above mentioned file makes
the NAND readable and my kernel boots, but this big fat warning ;-)
appears : NAND_ECC_NONE selected by board driver. This is not
recommended !!

Hello Jean-Christophe,

I'm working on a at91sam9m10ek, using latest origin/next.
The ecc-mode is "hardcoded" to NAND_ECC_HW in
arch/arm/mach-at91/at91sam9g45_devices.c. I've got the same -74 problem
when reading from the nand.
Barebox fails to read the environment, even if barebox has written it.
After changing the ecc mode to soft the env can be read and written
without problems.
I ported the atmel nand driver from linux-2.6.37, which had no
significant differences.
cheers, Marc

I just found in linux Kconfig:

The sam9g45 is not listed here....Maybe we should hardcode "soft" in
barebox for the 9g45

Marc

I prefer we detect it as we could change it the kernel
