Hi guys I have a MT29F16G08CBACAWP 2GiB chip with my am335x, uboot is able to erase/read/write to the NAND(only <0.1% bad blocks), but the kernel (3.2.0 from ti sdk) is complaining about its bad block issue.
I have also tried to use mtd-utils from ubuntu image. but flash_eraseall says 99% blocks are bad. and throw I/O error. I have tried at least with 5 chips, but no luck, exactly same issue.
Anyone had similar issue before? Give some debug directions or 2 cents? Thanks!
Kernel message is as follow:
