Good suggestions - Krunal note if you try this first one, you may have to write
a lot of data to filesystem2 before you see it overwrite the bootloader.
If it's completely erased then writing about 512MB (0x20000000) should cross
into the second chip select. But wear levelling abstration layers may move
things around or leave gaps.
I would try Steve's u-boot approach:
1) In u-boot, use the nand commands to erase, write, and dump. You
should be able to narrow it down to "writing to block N causes block
M to also change".
