Hello. I've installed FreeBSD 14.2-RELEASE on both my boards (RockPro64 and Khadas Edge V),both based on the Rockchip RK3399 and I've used a display that has a resolution of 720 x 720 resolution and I saw that the screen remains almost black (almost black (almost because I see a dim illumination coming from the display) .
I don't even see the u-boot logo. Instead,it is able to turn on my large HDMI monitor,which has a resolution of 1920x1080 pixels. Since I'm building a FreeBSD modular phone, I want to use a small HDMI display with a low resolution. Later I remembered that I had two displays,stored inside the shelf,that could be tested,to see if they work with u-boot and the khadas-edge-v. The first one is a 4 inch display,720x720 from waveshare,the second one is a 480x480 from a Chinese brand. The result that I've got is the same for both : https://drive.google.com/file/d/1InM4f4DLcYX8Y3ntERItnhwVuEnmHWeK/view?usp=sharing What happens is that u-boot is able to show the first stage of messages on the screen and then it becomes black and it remains black.... What's broken ? How to fix it ? Thanks. -- Mario.
