I'm trying to boot from an SD card, but I can only do it in "read-only" mode.
If I boot in "read-write" mode, it gives a kernel panic.
Bootargs for read-only:
setenv bootargs console=ttymxc0,115200n8 root=/dev/mmcblk1p2 ro rootwait rootfstype=ext4; mmc dev 2; fatload mmc 2:1 0x10800000 uImage; bootm 10800000
For read-write I use the same bootargs, just changing "ro" to "rw", and only then will it give a huge kernel panic.
