Hi mg.ax! TEZI uses our standard device tree for the apalis imx6 evaluation board (imx6qdl-apalis-eval.dts in linux-toradex). We use a 200Hz backlight, which most likely doesn’t work in your screen. In order to change it for TEZI, you can unpack the tezi.itb file with the mkimage utility and repack it with your custom device tree. As a quick fix you can also “disassemble” our device tree with dtc and modify the pwm value by hand, then recompile it and repack everything into the tezi.itb again. You can look up our model for tezi.its from the meta-toarex-tezi layer in GitHub - toradex/meta-toradex-tezi: Meta layer to build Toradex Easy Installer images to guide you in the process. Let us know how it works out!
