For some reasons, I modified the extlinux.conf in /boot/extlinux. Now I enter the uboot by serial console, I want to use ext4load and ext4write to modify the file in uboot. But when I use
- ext4load mmc 0 0x30008000 /boot/extlinux/extlinux.conf
Then I use md 0x30008000, the context is not what I want, can anyone tell me how to use ext4load or ext4write?
