More interesting than the kernel version would be to know which version of the MTD subsystem you are using. A 2.4.18 kernel sounds a bit old, so this probably means that the MTD code is even older? ... > CRC write error on /dev/mtd1: Input/output error > Error: can't write fw_env to flash ... > The respective environment sector has been erased, but writing the new > environment didn't work. > > If I insert a 'sync' command between writing on the rootfs partition and the > fw_setenv call, writing of the environment sector works, but this is not > really a solution??? No. Definitely not. Soulds like a MTD problem to me. > Any ideas, comments? Update the MTD code?
