micro_ros_setup: Conflicting instructions on how to add a custom message

According to https://micro.ros.org/docs/tutorials/advanced/create_new_type/

I added a new message in firmware/mcu_ws/custom_msg/msg/custom_msg.msg

But when I recompile it I get:

# ros2 run micro_ros_setup create_firmware_ws.sh mbed PORTENTA_H7_M7
Firmware already created. Please delete /microros_ws/firmware folder if you want a fresh installation.

I can not delete the firmware directory!!! It contains the files I was told to create!

Yes I satrted out using the https://github.com/micro-ROS/micro_ros_mbed repository and contribuited README fixes to that one.

But yes, I soon realized that I could not add custom messages to it, the documentation required some directories that did not get generated. So I switched to micro_ros_setup. I got it running today with rolling-ros-base-jammy docker, because mbed requires CMake >= 3.19.

It would be great to use the micro_ros_mbed repo to add custom messages, It seams to be smaller than micro_ros_setup.
