Hello.

I used the patch from you out of this posting: [U-Boot-Users] [PATCH RFC 3/5] i.MX31: Add i.MX31 NAND Flash Controller driver. http://lists.denx.de/pipermail/u-boot/2008-August/038239.html
They should work, or not? Do they require something else?
I haven't tried that driver on a recent U-boot so I don't know if (or how) it will work when applied to a recent U-Boot.
I'm using the u-boot master release of middle of June. How can I ensure that your patch is working? Or how do I know what is missing that it works?
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. But I think in a working u-boot thats no problem. But I will change that.
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).
