Serial console
- Manual is unclear about name of connector (J16 in schematics, J17 in manual).
- Also numbering of pins is not given afaict.
- Clone https://source.mnt.re/reform/pocket-reform.git
- Look at pocket-reform-motherboard.kicad_pcb
- From the PCB I can confirm J16 and pins numbered left (sysctl) to
right.
- attach "dtech" prolific PL2303 based serial to usb cable per serial console
section of PR manual
- lsusb shows
ID 067b:23a3 Prolific Technology, Inc. ATEN Serial Bridge

- A closer look at the PCB in kicad makes me realize the pin labels in the manual are wrong. 4 = GND, 5 =
UART1_RX, 6= UART1_TX. With that change I have U-boot output on boot.
