The only idea I have is that /dev/mtd1 might not be the place where barebox stores it's environment, maybe because of different probe order in the kernel or different partition layout. Could you send a hexdump of the first 256 bytes or so of /dev/mtd1?

bareboxenv on userspace - wrong crc on env
Hello all, I'm having issues accessing my barebox environment from within linux My barebox and environment are located on a SPI NOR flash. This boots ok, and barebox is able to save its environment to it. When I want to load it in userspace through: $ bareboxenv -l /mnt /dev/mtd1 Or $ dd if=/dev/mtd1 /tmp/barebox Or $ dd if=/dev/mdtblock1 /tmp/barebox Result is: Wrong crc on env However it's working fine in barebox itself What can be wron? ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
