Serial Console for the Rock64

[jekohk]

Hi,

I just received my RockPro64 and unfortunately am getting no display out of HDMI when I boot. Thus i'm trying to communicate with it over serial to see what's going on.

I did not want to wait 2 weeks for the Pine USB to Serial adapter to arrive so I ended up buying this adapter from Amazon https://www.adafruit.com/product/954

Unfortunately i'm still unable to get any input on my terminal from the board. I connected GND->GND, RX->TX and TX->RX, verified the device connected on ttyUSB0 and ran minicom with the following settings: `sudo minicom -s -D /dev/ttyUSB0  -b 1500000` but nothing.

Any tips would be much appreciated!

Reduce the bits per second to 115200, it is doubtful your usbtty device will communicate at the speed you are asking it to.

hmm still nothing unfortunately :/ I thought I read elsewhere on the forums that a USB with the CP2012 chipset would work with RockPro64 but maybe I was wrong? Really at a loss here, and hoping it's not a bad board I ordered.. anyone have suggestions for where to go from here? I do get a green light next to the power barrel and lights on the ethernet port so at least it looks like the board is getting power? But nothing from HDMI or USB ports (I tried plugging in multiple keyboards)
