I think I figured it out. I need to erase the spi nor flash first. I assumed the bareboxenv-target application did that for me... Am I correct?

bareboxenv-target and spi nor flash crc problem
Hi, I want to use bareboxenv-target on my operating system My environment settings are stored on a m25p32 spi nor flash. I can load them perfectly by issueing command: bareboxenv-target -l /tmp/barebox /dev/mtd1 I change something and afterwards I do: bareboxenv-target -s /tmp/barebox /dev/mtd1 No problems so far However If I reboot, I get a wrong crc on env superblock and default environment is loaded My barebox is latest v2013.10.0 and my kernel is 2.6.35.3 (freescale git maintain version) As a sidenote, I also still have problems with nand flash written with barebox, which is corrupt in linux and vica versa... ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
