Hello Martin,
UNO R4 openOCD plus simultaneous serial connection?
I don't have the hardware to check but would expect [1] two virtual COM
ports to be provided over the one physical USB-C connection; a debug
port you can use with openOCD etc. and a serial port you can use
simultaneously with minicom etc. or amforth-shell.py
Best wishes,
Tristan
[1] from previous comments I'm guessing you have the UNO R4 Wifi and not
the UNO R4 minima

That's a great write up, Tristan. I need to figure out a way to debug
scenarios requiring user input. I'm currently using the same USB
connection
for connecting OpenOCD to the board, so I can't run serial I/O while
I'm
debugging. I'm guessing there isn't any simple solution that won't
require
a separate debug connection, I just haven't figured out how to do that
yet.
The best workaround I could think of is to simulate input by preloading
the
TIB with the content I'd type in, although that's fairly cumbersome.
Currently I just code up the scenario I want to debug in the turnkey
word
and throw an XT_HALT word in there somewhere (halt just invokes
wait-for-interrupt instruction which isn't quite a halt instruction but
does the job while I'm not really using interrupts for anything), and
then
reset the board under debugger.
