Modern flash chips actually rely on specific forms of cyclic redundancy
checks in order to be able to correct for bit errors in NAND flash.
Without using the proper CRC algorithm, you can never be sure to be able
to read from the flash what you have written to it. Another hint at this
problem are the "Bad eraseblock" messages that follow.
Check your kernel configuration and the documentation of your target for
the proper ECC settings for the NAND flash.
With kind regards
Stefan Peter
