Raspberry Pi Pico C/C++ Programming on Manjaro/Arch Linux Setup and No-Boot-Button Guide

# Start with installing dependencies 
# Manual insallation might be required for some refer to https://dev.to/nabbisen/installing-aur-packages-bdf
sudo pacman -Sy minicom openocd cmake arm-none-eabi-gcc arm-none-eabi-newlib gcc

# clone all the base repos in a dependency folder
git clone https://github.com/raspberrypi/pico-sdk.git
git clone https://github.com/raspberrypi/pico-examples.git
git clone https://github.com/raspberrypi/pico-extras.git
git clone https://github.com/raspberrypi/pico-playground.git

# Update these paths to match where you've checked out the repos
echo 'export PICO_SDK_PATH=/home/jamon/code/pico/pico-sdk' >> ~/.bashrc
echo 'export PICO_EXTRAS_PATH=/home/jamon/code/pico/pico-extras' >> ~/.bashrc

# read in the env variables we just set
source ~/.bashrc

# pull in the git submodule dependencies in the pico-sdk and pico-extras projects
cd pico-sdk
git submodule update --init
cd ..

cd ../pico-extras
git submodule update --init
cd ..

# clone/build picotool that enables the no-boot-button fix
git clone https://github.com/raspberrypi/picotool.git
cd picotool
mkdir build
cd build
cmake ..
make

# now we can run picotool using ./picotool in /picotool/build/
# do not forget to create symbolic link 
sudo ln -s ~/picotool/build/picotool /usr/local/bin/picotool

# Adding alias for ease of use
nano ~/.bashrc

# add followig
alias sudo='sudo  '
alias picotool='/..../picotool/build/picotool'

# source again
source ~/.bashrc

# example for how to build from command prompt:
cd pico_examples
mkdir build
cd build
cmake ../ -DCMAKE_BUILD_TYPE=Debug

cd blink
make -j4 # you can update this 4 to be how many CPU cores you want to build on

# IMPORTANT NOTE #
# It is needed to edit CMakeLists.txt in order to enable stdio_usb_init() function as explained below
# if (TARGET tinyusb_device)
#     add_executable(hello_usb
#             hello_usb.c
#             )
# 
#     # pull in common dependencies
#     target_link_libraries(hello_usb pico_stdlib)
# 
#     # enable usb output, disable uart output
#     pico_enable_stdio_usb(hello_usb 1)
#     pico_enable_stdio_uart(hello_usb 0)
# 
#     # create map/bin/hex/uf2 file etc.
#     pico_add_extra_outputs(hello_usb)
# 
#     # add url via pico_set_program_url
#     example_auto_set_url(hello_usb)
# elseif(PICO_ON_DEVICE)
#     message(WARNING "not building hello_usb because TinyUSB submodule is not initialized in the SDK")
# endif()


# As well as


# #include <stdio.h>              // stdio library is needed for function below 
#     stdio_init_all();           // This function in the compiled C/C++ code enables stdio_usb_init() which is required in 
#                                 // no boot button fix 

# After compilation of project there exist output file named PROJECT.uf2 inside build directory which is used with
# picotools to be initialized on the controller.

# [ozgur@ozgur blink]$ sudo picotool load -f blink.uf2 
# [sudo] password for ozgur:

# The device was asked to reboot into BOOTSEL mode so the command can be executed.
# 
# Loading into Flash: [==============================]  100%
#
# The device was asked to reboot back into application mode.
