Hi Scott and others,
I have a question regarding BBT position and number of blocks allocated
for BBT.
Did you face the issue with last 4 blocks broken in any NAND flash
device since the default option in Linux/u-boot BBM is last 4 blocks?
It doesn't mean that if the last 4 blocks are broken than the NAND flash
device is broken too.
Also I haven't seen any common binding for Linux kernel to change it.
Has someone tried to improve this algorithm or process of storing BBT in a better way.
For example just look for BBT from the end till any limit?
Thanks,
Michal
