I'm looking for a way to update the uImage stored in the flash from linux userspace (without using uboot).
The flash is separated into 3 partitions:
2) persistent data (jffs)
Now I want to tftp or scp the new uImage.ext2 from a remote host into the target's ram and than burn it directly into partition 3. But I'm a bit lost.
1) Is it even possible do burn/write something into a partition that is not mounted?
2) Which command do I need? With fw_set_env and fw_get_env I'm able to manipulate the uboot-env-variables, but that does not help me to burn anything.
Thx for your help.
