I'm using U-Boot on a Raspberry Pi Compute Module. The boot process is : RPi firmware --> U-Boot --> Linux
I'm setting up some things about devices in the config.txt, that is used by the RPi firmware. But when I re-load the DTB with U-Boot, it actually erase the settings done by the RPi firmware, and some devices won't work in Linux.
I boot using the bootz command, and I can't use it without giving it a DTB, or it will crash at booting Linux ...
Do you guys have an idea of how I can boot without reloading a fresh DTB ?
