GXL p231 devices. NG test build

[ashi]

Unfortunately still no video output on KII Pro 905D, same as

Amlogic-ng does not boot on MECOOL KII Pro (S905D)

I know this is experimenta,l but when selecting the above device from the downloads page there is a text saying that it is supported by -ng builds. So I gave it a try on a spare micro sd card, copied gxl_p231_2g_dvb.dtb to dtb.img. The result is that it shows the MECOOL logo and then switches to a black screen where it stays forever. Searching this forum, I found no results. Can anyone confirm?
