Arduino IDE v2 debuging suport

hathach commented 1 year ago

IDE v2 support debuging, this add neccessary config and script to debug with both M0 and M4. - supported probes is cmsis-dap (daplink) such as pi debug probe. https://www.adafruit.com/product/5699
I also try to add jlink over openocd but menu selection build.openocdscript isn't picked up with IDE (probably its bug). Therefore commented out for now
JLinkGDBServer can be used by debug_custom.json in the sketch folder https://docs.arduino.cc/software/ide-v2/tutorials/ide-v2-debugger#j-link and 2 template json are also include for user convenience at https://github.com/adafruit/ArduinoCore-samd/tree/ide2-debug/scripts/jlink/samd21 & samd52
debugging samd51 requires at least openocd v0.11. index json will bump up openocd version. For now to test out PR, you can install mbed rp2040 core which has openocd 0.11.0 as deps

itsybitsy M4

Note: Metro M4 mux swd pin with neopixel or so, and is difficult to test with

I am trying it out, but unclear of the best way to force the M4 to use the 0.11.0 openOCD. I do have that version installed but it is not finding the config file.

Will debug more tomorrow

Quick update.

@mjs513 - tested on the M0, and showed his changes to platform.txt to force using OpenOCD 0.11, which I did and it now work on my Feather M4 express.

For what it is worth, I am using an Raspberry Pi Pico as the CMIS-DAP using a free-dap image. https://github.com/ataradov/free-dap

@KurtE thank you for testing, another daplink can be used with pico is https://github.com/raspberrypi/picoprobe , which is the firmware running on pi debug probe. It has an advantage that implement multidrop and can also be use to debug another pico.
