Hi, 2011/2/10 Jean-Christophe PLAGNIOL-VILLARD <plagnioj@xxxxxxxxxxxx>: > Hi, > >    Âwhich ecc did u use before? 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 !! Regards, Mickael > > Best Regards, > J. > On 12:09 Thu 10 Feb   , Mickael Chazaux wrote: >> Hi, >> >> I managed to compile Barebox for AT91SAM9G20-EK, and I can run it.
