I tried to port this on top of Sascha's patches for imx53, only for mxc v3 for now, as below. Unfortunately, I still get: ... UnCorrectable RS-ECC Error UnCorrectable RS-ECC Error UnCorrectable RS-ECC Error UnCorrectable RS-ECC Error UnCorrectable RS-ECC Error ... from mxc_nand.c's mxc_nand_correct_data_v2_v3(). Maybe there's still sth. missing in the error correction code?
With the below incremental fix, it works. :-) Thanks, Roland PS: Will you prepare a patch for l2-mtd.git? I only have an imx53, can't test the v1/v2 etc. configs.
