Building debug libmbed.a

[KurtE]

Doing a clean build... I removed both the mbed directory under hardware as well as the directory /tmp/mbed-os-program

EDIT:
Some initial steps

sudo apt install gcc-arm-none-eabi
sudo apt install python3-poetry
sudo apt install python3 python3-pip git mercurial jq

git clone --depth 1 https://github.com/arduino/ArduinoCore-mbed.git mbed
<git the API stuff and create link>
cd mbed
poetry init
Edit file pyproject.toml to add a line:  
Note: appears like this is not needed on RaspberryPi and will give you errors.
`package-mode = false`

poetry add mbed-tools
poetry add mbed-cli
poetry add setuptools
poetry install (did not do anything)
poetry shell
./mbed-os-to-arduino -a -g GIGA:GIGA

And it built...

Compile [ 99.6%]: serial_api.c
Compile [ 99.7%]: trng_api.c
Compile [ 99.8%]: us_ticker.c
Compile [ 99.9%]: watchdog_api.c

EDIT: Fix for using the generic CMSIS-DAP adapter by Alex Taradov on Ubuntu

I did a bit more investigation into the subject of the udev rules for the "Alex Taradov CMSIS-DAP Compliant SWD Debugger".

The rule I provided in post #32 is for the 6666:9901 VID/PID pair produced by the firmware on @KurtE's probe, but I noticed that my probe has the VID/PID pair 6666:6666. I found that there are multiple versions of the open source firmware, and each version has its own VID/PID pair. So I expanded the rules to cover all versions of the firmware:

# CMSIS-DAP Compliant SWD Debugger by Alex Taradov:

You can quickly install and activate it by running this command from the terminal:

Fix for @wwatson building on RPI5 with Ubuntu 24.04 to downgrade pyelftools
Also maybe needed for RaspberryPI OS

@ptillisch

poetry add pyelftools@0.29

Side Note: I was also able to build it using WSL on my Windows 11 machine, and was able to copy out the updated directory to a location that could be seen by Arduino 2.3.3 in my sketch folder.
