We are having an issue changing to a custom DTB file with version 3.0b4.254.
Using Easyinstaller I erased the flash, then loaded the console image for 3.0b4.254 from the Toradex servers.
From the u-boot prompt I executed the env default -a to reset the environment.
I then changed the fdtfile by
setenv fdtfile myfile.dtb saveenv
I then print the environment with printenv and see that the fdtfile has been changed to myfile.dtb. I power cycle the board and when it boots up the fdtfile reverts back to fsl-imx8qm-apalis-eval.dtb.
Am I doing something wrong?
