problem with env in NOR

problem with env in NOR

Hello,

on my PXA270 I put a splash image into the environment. The env image
with the splash image covers more than one flash sector. (The flash
sector size is 256 KiB.)

Loading the environment fails:

uboot:/ loadenv /dev/env0
loading environment from /dev/env0
read: error -262116

(This fails during boot, too.)

[frogger@hardanger:barebox (dev/pxa270)]$ grep CFI .config
CONFIG_HAS_CFI=y
CONFIG_DRIVER_CFI=y
# CONFIG_DRIVER_CFI_NEW is not set
CONFIG_DRIVER_CFI_OLD=y
CONFIG_CFI_BUFFER_WRITE=y

Sascha it's probably the problem we discussed the other day, that the
cfi driver doesn't handle the offset correct. I haven't looked at the
code though.

Cheers, Marc

Yes, saveenv probably saves the whole environment with one write call
whereas other writes usually don't cross sector boundaries and so the
bug never showed up
