I create the environment with uboot-envedit (I prepare it on the desktop PC
and just copy the binary over to the Freerunner and write it to the flash).
I have no "ro" after $mtd_parts and just "uImage.bin" in the root-directory
instead of "/boot/uImage.bin".

Yes, and all 4 partitions work. Notice that mmcblk0p6 also starts beyond
the 4 GB that Andy mentioned. Try to make the first 3 partitions 1 GB only
(your last message has just arrived while I was writing this).
