Hi all,
i am trying to write MLO, u-boot.img, uImage and ubi.img files to NAND and trying to boot from NAND on my custom board. Though i have previously flashed NAND and have successfully booted from NAND on same board, using same procedure but now i get error below while writing to NAND from Linux.
