RP2350B-MINI-A picotool Tutorial

【Picotool installation tutorial】

】Install necessary dependencies

You need to install the development environment and ARM cross-compilation tool chain required for compilation first.

sudo apt update

sudo apt install build-essential cmake gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib pkg-config libusb-1.0-0-dev

【Get the source code】

Create a working directory (e.g. pico) and clone the official repositories of pico-sdk and picotool.

mkdir -p ~/pico

cd ~/pico

git clone https://github.com/raspberrypi/pico-sdk.git

git clone https://github.com/raspberrypi/picotool.git

After cloning is complete, you need to initialize and update the submodules within pico-sdk.

cd ~/pico/pico-sdk

git submodule update --init

【Setting environment variables】

You need to tell the build system the location of pico-sdk.

】Temporarily set environment variables：

export PICO_SDK_PATH=~/pico/pico-sdk

】Setting environment variables permanently：

sudo nano ~/.bashrc

Add to

export PICO_SDK_PATH=~/pico/pico-sdk

Then execute

source ~/.bashrc

【Compile and install picotool】

cd ~/pico/picotool

mkdir build

cd build

cmake ..

make -j&nproc # Compile using multiple cores to speed up

sudo make install # Install picotool to the system path (such as /usr/local/bin)

【Verify Installation】

picotool help

If successful, a list of all available commands and options is displayed, indicating that the installation was successful.

【Read device information】

Make sure the Pico is in BOOTSEL mode (shows up as an RPI-RP2 disk when connected to the computer). Then do

picotool info
