I’m having trouble getting a Pico 2 to work with the RPi debug probe using the PlatformIO plugin on VS Code, as the debug console always hangs at the [quote]PlatformIO: Initializing remote target…[/quote] stage when a debug session is started.
My platformio.ini file is:
[env:pico]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = rpipico2
framework = arduino
board_build.core = earlephilhower
upload_protocol = cmsis-dap
debug_tool = cmsis-dap
debug_speed = 5000
build_flags =
-D ARDUINO_RASPBERRY_PI_PICO
-D ARDUINO_ARCH_RP2040
debug_port = /dev/tty.usbmodem1102
Both the yellow and green LEDs are on for the 'D" port of the debug probe, so the probe can see the Pico, but apart from a brief flash the ‘U’ port LEDs are out. On the ‘Devices’ window of PlatformIO both the Pico and the Debug Probe are showing as USB connections.
Programs upload and run on the Pico without problems, it’s the debug that’s the issue.
Starting a debug session with the blink program running gives the following output…

… and that’s it. Setting breakpoints or monitors in the code has no effect so I’m assuming that the debug has failed to initialise
I’m assuming it’s not a hardware issue as the 3 wires from the debug go straight to the Pico as in the documentation
so it’s more likely to be a software/config problem? Does anyone have experience with this setup?
Thanks
