Mounted the AlloBoss DAC.
Insert the SD with dietpi AlloGUIv7 without changing anything in config.txt.
Boot but no HDMI.
Tried different HDMI 1.4 cables but i cant get a picture.
Both mini HDMI Ports tested.
Waited and accessed the rpi via ssh.
In the Display Options i realised i need to freshen up my knowledge on which Resolution in HD i am going to be using.
Anyway tried with all top three ones.
Code: Select all
vc4-kms-v3d-pi4 : OpenGL | 1920 x 1080 vc4-fkms-v3d : OpenGL | 1920 x 1080 1080p : 1920 x 1080
Decided to update,
Update RPi4 EEPROM firmware : [Bootloader: 1599135103 | VL805: 000138a1]
During the Reboot i was able to see some Red background with Text on the Screen for less then a second which at least meant cable is working.
Right now i am guessing the AlloBoss even though not configured is sucking to much power, unfortunately i do not have a usb-c power supply to test this. I can though unscrew everything and test the rpi4 without the AlloBoss DAC.
