Simple project for the Pi Pico to serve as template. The application is actually the blink project from pico-examples.

Most of the steps are close to the official Getting Started guide. I did not used the pico_setup.sh because I didn't wanted to use VSCode.

For Windows, I used WSL with Debian (Ubuntu should also be fine) and can pretty much follow the official procedure for Linux.

I also decided to use Ninja instead of Make but there should be no differences.

sudo apt update
sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential ninja-build

Then go into this template folder and init all submodules

git submodule update --init --recursive

Run cmake to generate build files

cmake -Bbuild -G "Ninja"

Go into build directory and build the project

cd build
ninja

The uf2 file will be located in build/src/PicoTemplate.uf2. Simply copy this file to the RPi folder after connecting a usb cable to the Pi Pico while holding the BOOTSEL button.

Follow instructions to build openocd and install gdb(-multiarch). I can confirm that it works on WSL.

To pass the usb from Windows to linux, use usbipd.

sudo src/openocd -f interface/cmsis-dap.cfg -c "adapter speed 5000" -f target/rp2040.cfg -s tcl

gdb-multiarch src/<application-name>.elf

target remote localhost:3333
load
monitor reset init
continue

Then use gdb commands
