I’m working on a Toradex Apalis, I loaded an image of Boot2Qt on mmc and I want to boot on it by default, so I entered on UBoot and want to change bootcmd from “run distro_boot” (who launch scans to execute a boot.scr I don’t know where) to “run emmcboot” who works perfectly by loading the kernel.
Here’s the problem, the saveenv command does not exist, so I need a way to figure out how to run this emmcboot automatically.
I’ve been thinking to 3 possibilities but I don’t know how to procede them :
- I find a way to manipulate environnement variables without saveenv, maybe with the direct memory address ?
- I write a script boot.scr who contains “run emmcboot” but I don’t know where to put this script, I don’t understand which memory/partition is scan to find it
- I load another UBoot on my toradex, the missing of saveenv seems to be a issue on this particular version, but again, I don’t know how to procede and it’s a dangerous operation
Thank for your help
