NAND flash and BBT management

Davp

Hi, i have used til now only two times my TL866II+, i have some confusion about the NAND programming, i have read the content of one nand and i know there are two bad blocks on it, does have sense and how to do rewriting the dump skipping bad blocks and rebuilding the BBT (bad blocks table) to let the device's software to ignore them and write in the wide free space?? Thanks!

i suspect that bad block management does not work as it is hoped to be, i have read a nand flash content from a Sharp tv, i tried to recycle that chip hoping that using the skip bad block function it would have skipped writing the bad blocks on the chip and wrote the content of the dump relative to that blocks to the next good blocks but i think it have skipped data from the dump! The previously booting system now don't even boot any more..
plus a little note at bottom, if you add Weltrend microcontrollers support i can sell my RT809F, i will not need it any more..
