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?
Grtz,
Wouter

You should use flash_erase (from mtd-utils) on the mtd partition before
writing to it.

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...
