If I recall correctly the bad block information is essentially just a table on the NAND that uboot itself maintains. So if the same NAND image is copied to all boards they would list the same bad blocks information. NAND flash is pretty basic, it doesn't keep info about bad blocks itself. It's up to the controller/code to maintain that information somewhere.
I see. Thanks for the clarification! So I should be able to recover and use those bad blocks using U-Boot commands and store data of my own, right?
Hello Everybody,
I recently got an EBAZ4205 board. U-Boot reports the last 5 sectors of the nand flash as bad blocks:
I wouldn't give it too much importance if it weren't because it seems that all boards have exactly the same sectors marked as bad blocks. I do not believe in coincidences, even less in this one.
Does someone know if there is any particular reason for which all boards seem to have these bad blocks? Or are there lucky people who got an ebaz4205 with a healthy nand flash?
Thank you very much for your time and your support!
