Black screen. There is no image, not even the console after installing the firmware.

Tried Linux 4.19.0 and 5.3.0 on Debian 10

cpu: AMD A6-7480 Radeon R5, 8 Compute Cores 2C+6G

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Carrizo (rev e6)

I connected via ssx and saw that xrandr does not show connectors correctly

DISPLAY=:0 xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 16384 x 16384
HDMI-1 disconnected primary (normal left inverted right x axis y axis)

Only Dsub on the board. F2A68HM-S1
