Hi! if you stumbled upon this github repository you might be looking to work with your rp2040 on a lower level or trying to understand how it works.. that's what i was trying to do here! The code contains nothing special, so here's
- Debian Bullseye
- pico-sdk 1.5.1
- vscode
- cortex-debug vscode extension
So three things to note:
- The guide i initially followed is old and uses deprecated configs and executables, so i made my own config file:
{
"version": "0.2.0",
"configurations": [
{
"name": "Pico Debug",
"cwd": "${workspaceRoot}",
"executable": "${command:cmake.launchTargetPath}",
"request": "launch",
"type": "cortex-debug",
"servertype": "openocd",
// This may need to be arm-none-eabi-gdb depending on your system
"gdbPath" : "gdb-multiarch",
"device": "RP2040",
"configFiles": [
"interface/cmsis-dap.cfg",
"target/rp2040.cfg"
],
"openOCDLaunchCommands": ["adapter speed 5000"],
"svdFile": "${env:PICO_SDK_PATH}/src/rp2040/hardware_regs/rp2040.svd",
// Work around for stopping at main on restart
"postRestartCommands": [
"break main",
"continue"
],
"searchDir": ["your path to tcl here"],
}
]
}-
For whatever reason the svd file provided when you install the pico-sdk doesn't work, at least in my case it doesn't let you mess with the peripherial registers and shows them all as read-only, so you will need to download this one instead and replace the old one with it
${env:PICO_SDK_PATH}/src/rp2040/hardware_regs/rp2040.svd. -
Make sure to download the right firmware if you're using an rp2040 to debug another rp2040 select the downloads with the name "picoprobe" and not "debugprobe"
