I'm trying to get two separate pine64 LTS boards to boot for the first time. Previous troubleshooting attempts here: https://forum.pine64.org/showthread.php?tid=17961.
I was hoping to monitor the serial port of each board to find some some helpful errors. I couldn't find a post specifically for the pine64 LTS but I did for the rock64: https://forum.pine64.org/showthread.php?tid=5029. I connected to pin 6 (GND <-> GND), pin8 (TX -> RX), and pin10 (RX -> TX). As a sanity check I switched RX and TX to make sure I hadn't mis-connected something. I've tested the serial console on another dev board so I know it's working. I'm on Ubuntu 22.04 and I'm using the following command to read messages:
I checked that the serial console is connected to /dev/ttyUSB0 by using the command:
Absolutely nothing comes through minicom from both boards. I thought perhaps the steps for the rock64 are different for the pine64. Please enlighten me if so.
