You need to use either a debugger or add printf's to see what's going on (to the mxc_nd.c or whatever the file is called. >> Did you define the following two as well (they might have been renamed >> since last year). >> #define CFG_ENV_OFFSET 0x40000 >> /* CFG_ENV_SIZE has to be a multiple of the NAND block size */ >> #define CFG_ENV_SIZE (128 * 1024) >> >> If CFG_ENV_OFFSET (or perhaps it's called CONFIG_ENV_OFFSET nowadays) >> is zero, then 'saveenv' will overwrite your existing redboot. > > Yes, I defined them and you're right my offset was zero.

I do think that's a problem in a working u-boot since it defines the offset for the environment from the start of the flash. > > In your previous mail you mentioned a newer nand driver patch for the i.MX27. > Do you mean this one? > http://lists.denx.de/pipermail/u-boot/2009-June/053898.html Yes. > Does this one work with i.MX31 aswell? Don't know, but the author claims that it should work (perhaps with some adjustments).
