How to configure VFD

Sorry, I forgot that you also need to replace the DTB file.
Use this one: gxl_p281_2g_a95xr2.dtb or gxl_p281_1g_a95xr2.dtb if it’s a 1GB ram box
You can run the following commands:

mount -o remount,rw /flash
cp /usr/share/bootloader/device_trees/gxl_p281_2g_a95xr2.dtb /flash/dtb.img
reboot
