I'd something like this:

dd if=/dev/zero of=zero bs=10240 count=1
flashcp -v zero /dev/mtd1
memtool md -s /dev/mtdblock1 0+0x2800 | grep -vE '(0{8} ){4}'

flash_erase /dev/mtd1 0 0
memtool md -s /dev/mtdblock1 0+0x2800 | grep -vE '(f{8} ){4}'

If both grep don't yield any lines, retry flash-kernel.

Best regards
