How to rewrite uboot to emmc
#4
>Is the manjaro-arm-flasher erasing the uboot installed on the emmc? How can I check that?
Probably, it is a complete image I would guess, mbr and uboot are there in 1st 16M
If/when you install bsp uboot, nothing is erased, the 1st 16M is UNCHANGED
The new uboot and idbloader (and trust - likely) are in /boot
so the usual dd commands (example simplified)
cd /boot ; su
dd if=idblo... of=/dev/whatever seek=64 (dd default bs=512B)
dd if=uboot... of=/dev/..... bs=1M seek=8 (I do a little different, easier I think)
If trust,, bsp usually has, mainline not, mainline uboot.itb has trust within
dd if=trust... of=/dev/.... bs=1M seek=12
