Please make sure your partitions are aligned to eraseblock boundaries, usually 128k. so: addpart /dev/nand0 512k(barebox)ro,128k(bareboxenv),3M(kernel),-(root) barebox currently does not enforce this, it's probably time to change this. Unaligned partitions are fine, but the partition code should mark them as readonly. Currently we have no way of passing the eraseblocksize through to the partition code, so it's not trivial to enforce alignment.
