Hi everyone,
I have some issues relating to hdmi and network with my rk3228 tv box with emmc. Simply put, the box boots normally at the first glance, but both the hdmi output (the signal is there, just black screen) and the network disappear exactly after the system asks me to login. So I cannot ping it, nor can I ssh to it, and there is no display. Before that, I can see its ip address in my router and ssh to it when I'm lucky. But the ssh freezes immediately as well. An LED on board goes off at the same time.
I tested serveral power supplies, including an original 12v1a and a new purchased 12v2a. The tv box itself recommends using a 12v1a power.
I tested several armbian images (ranging from legacy kernel to current kernel) into the emmc on board, following the instructions of jock using rkdeveloptools:
These images all behave the same.
Any ideas? I don't even know whether this is a problem relating to hdmi and network configuration, or armbian just went down! I do not have the ability to do ttl or uart tests and I know nothing about that. I'll attach the image of this board.
Thanks a lot!
