Yes, but this is the kernel partition. The rootfs starts at a lower address. And actually this is the problem: I put uboot into the RedBoot flash partition, which is only 0x40000 in size (256 kB), but uboot apparently needs much more. Which raises the question: why is the environment so large? Wouldn't a few kB be enough (4kB, 16kB for example)? Thanks, also to Elie, for the quick answers. I'll get it to work now.
