Kernel update on ReadyNas 1022016-02-06
This is what I use for flashing and updating the kernel on the ReadyNas from user space:
flash_eraseall /dev/mtd2 nandwrite -p /dev/mtd2 uImage-v4.4.1
Seems to work :), but always be careful when writing to the NAND. So double check so that the MTD partitions are the same on your machine.
