Problem changing FDTFILE on 3.0b4.254

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?

Hi @mccandlt

Thanks for writing to the Toradex Community!

I can reproduce your issue. I will check internally for a solution and come back to you.

Thanks and best regards,

This issue should be fixed in a next release. As a workaround I can suggest just replace existing fsl-imx8qm-apalis-eval.dtb with your DTB keeping old name. You can do it from Linux console by accessing /media/mmcblk0p1/
