Hello :)
I have the board with u-boot and I want modify the firmware.
To modify I must find rootfs files. I look for the files firmware (hexedit)
and I don't visible the rootfs files. vmlinuz I'm extract good.
What I must do to etract the rootfs ( I must find the dir: /etc/ /home/)???
Please help me and sorry for me english :)
