The opposite (haven the "same" sdcard in both slots) doesn't help either ;)

VFS: Cannot open root device "mmcblk1p2" or unknown-block(179,26)
Please append a correct "root=" boot option; here are the available 
partitions:
b300         7757824 mmcblk0  driver: mmcblk
b310            2048 mmcblk0boot1  (driver?)
b308            2048 mmcblk0boot0  (driver?)

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-
block(179,26)



I tried to boot from SD2 only.
When switching the DIPs 1 and 2 he loads uboot from SD2, but I can't get 
'fatload mmc' working when booting from SD2
