Dear Schleifer, Alexander, > But I found out, that the AT91Bootstrap initialization impacts
the U-Boot code. If I use the AT91Bootstrap (without mci initialization) from NAND flash, the mmc init command successfully reads the card. It fails if I use the AT91Bootstrap with mci initialization. That's unlikely (it has the same init sequences)... Do you have at91_mci_hw_init(void) in your at91samXXXX_devices.c and do you call that function from your board init? Can you list me what that bootstrap does initialize differently if mci is enabled?
