Problem about auto detection of port

[asukiaaa]

You introduced auto detection on an issue thread platformio#2

It works if /media/${USER}/RPI-RP2 presence with the following setting.

[env:pico]
platform = git@github.com:maxgerhardt/platform-raspberrypi.git#develop
; platform = raspberrypi
board = pico
framework = arduino
upload_protocol = mbed
upload_port = /media/asuki/RPI-RP2

However, does not work if /dev/ttyACM0 is mounted.

Thank you.

I have a similar problem

I'm using Manjaro Linux (Arch based).

Either I don't set a upload protocol/port, then the upload protocol "knocks" on the /dev/ttyACM0 port and the pico restarts and the virtual disk shows up and is mounted (by the OS) at /run/media/username/RPI-RP2*, but the picotool seems to not get that and times out, although the path exists and is readable/writable by the user, while picotool is still running.

If I manually copy the firmware file with a simple cp .pio/build/pico/firmware.uf2 /run/media/username/RPI-RP2/ after the failed upload process, the file gets copied, Pico restarts and all is fine.

Or I set the upload_protocol = mbed together with upload_port = /run/media/username/RPI-RP2. Then the Pico doesn't restart automatically anymore (no port knocking) and I need to manually unplug and re-plug it, holding the boot select button (which is even more cumbersome).

Unfortunately, I can only get one of those behaviors, but not both.

What I'm looking for, is a process that first knocks on the port, waits until the Pico restarts, the fs is (auto-)mounted and then starts the upload/copy part.

*/media/username/RPI-RP2 works too, it's just a symlink to /run/media/username/RPI-RP2.

This is my current platformio.ini:
