2 - I'm not sure why, but I was advised to make sure the TX line of the UART adpter was runnig at 3v3. Not at 5V.
The RockPro64 GPIO where the UART transmits from operates at 3.3v. This is also true of the Raspberry Pi GPIO, which is what the RockPro64 GPIO is modeled after. If I remember right, the logic chip that interfaces with the GPIO operates at that voltage.
Quartz64, RockPro64, PinePhone Mobian, PineBook Pro, PineTime, and all the trimmings that make FOSS fun.
