Firmware upload failing with Teensy 4.0, ROS Humble

[RicardoSPeres]

Hi, calibration works fine but the firmware upload stopped working (had it previously running fine around November 2023 on the same robot). I saw the suggestions on #35 and also experimented with changing the lib_deps in linorobot2_hardware/firmware/platformio.ini to match the different branches (rolling, foxy and humble) but it still fails.

Also, I just tried a fresh install, linorobot2_hardware is outside my workspace folder.
Any help is appreciated, thanks.

Here's my lib_deps:

lib_deps = https://github.com/micro-ROS/micro_ros_platformio#22cf9b631b0bbb8861c30469e33b24e9241819ef
    https://github.com/micro-ROS/micro_ros_utilities#2.0.0
    https://github.com/linorobot/rosidl_typesupport_introspection_c

And the output after running pio run --target upload -e teensy40:

rsp@novamob:~/linorobot2_hardware/firmware$ pio run --target upload -e teensy40

It is upload problem. It is teensy-cli/platformio issue. I tested with a teensy41 (with the same MCU as teensy40) and got the same issue. The second upload will success. It is not related to linorobot2_hardware project.
