I will try that. I did more tests and I think that the ECC errors I was getting in the first post I have them only if the FIT image is greater than 50 MB. It does not matter the ECC/BBT options in bootloader/kernel or the kernel version. Do you know any limitation of the UBI FS in terms of image/partition size?
