Hi Jean,
Hi,
I use the last uboot from your git and boot with it on AM3517 EVM from SD card without NAND.
I use this option in uboot config : #define CONFIG_FAT_WRITE 1
I use intensively fatload / fatwrite commands at the boot before kernel loading.
Sometimes, in about 2% of cases of boot, the FAT becomes inconsistent and I have systematically these messages at boot when I use fatwrite command :
U-Boot 2013.01-gd3b9a66-dirty (Feb 21 2013 - 11:02:33) ... writing MODIFYME.001 mmc_send_cmd: timedout waiting on cmd inhibit to clear
Those kind of errors are caused by exceeding timeout for receiving response from your SD card.
Could you try with other (different manufacturer) card?
It seems like card/vendor specific - it depends on the firmware on the SD card.
