Hey @farina!
Glad it worked! I also find it strange it didn’t make the kernel panic.
About your device tree issue, perhaps you have to update your U-Boot environment variables so to load the correct .dtb file.
Check fdt_file environment variable on U-Boot. Its value should be the filename of the device tree to be loaded. Try modifying this variable from within U-Boot ( setenv fdt_file [...] ) and check if the correct .dtb is loaded.
On your Toradex Easy Installer image, check the uEnv.txt file. These are the default environment variables to be loaded by U-Boot. You can modify this file after you generate an image so to have the correct variable referring to your custom .dtb.
