Hi friends,
I use armbian for long time, but these days I change my borad to RaspberryPi 4B.
However I can not get kernel startup serial output from RPI as usual on the board. Does anyone has more information about that?
What I want to do is a atonomy driving experiment environment. And I don't have monitor or keyboard attach to it.
I will patch preempt_RT to get the RT linux kernel, so it's difficult for me to pull the RPI out of the test bench everytime and put back after setting the ssh or something everytime I flash new kernel or image.
The armbian version I use is
Armbian_23.11.1_Rpi4b_jammy_current_6.1.64.img
Thanks in advance.
