# Building CircuitPython
Welcome to CircuitPython!
This document is a quick-start guide only.
Detailed guides on how to build CircuitPython can be found in the Adafruit Learn system at
https://learn.adafruit.com/building-circuitpython/
## Setup
Please ensure you setup your build environment appropriately, as per the guide. You will need:
* Linux: https://learn.adafruit.com/building-circuitpython/linux
* MacOS: https://learn.adafruit.com/building-circuitpython/macos
* Windows Subsystem for Linux (WSL): https://learn.adafruit.com/building-circuitpython/windows-subsystem-for-linux
### Submodules
This project has a bunch of git submodules. You will need to update them regularly.
git submodule sync
git submodule update --init
### mpy-cross
As part of the build process, mpy-cross is needed to compile .py files into .mpy files.
To compile (or recompile) mpy-cross:
make -C mpy-cross
# Building
There a number of ports of CircuitPython! To build for your board, change to the appropriate ports directory and build.
Examples:
cd ports/atmel-samd
make BOARD=circuitplayground_express
cd ports/nrf
make BOARD=circuitplayground_bluefruit
If you aren't sure what boards exist, have a peek in the boards subdirectory of your port.
If you have a fast computer with many cores, consider adding `-j` to your build flags, such as `-j17` on
a 6-core 12-thread machine.
# Testing
If you are working on changes to the core language, you might find it useful to run the test suite.
The test suite in the top level `tests` directory. It needs the unix port to run.
cd ports/unix
make axtls
make micropython
Then you can run the test suite:
cd ../../tests
./run-tests
A successful run will say something like
676 tests performed (19129 individual testcases)
676 tests passed
30 tests skipped: buffered_writer builtin_help builtin_range_binop class_delattr_setattr cmd_parsetree extra_coverage framebuf1 framebuf16 framebuf2 framebuf4 framebuf8 framebuf_subclass mpy_invalid namedtuple_asdict non_compliant resource_stream schedule sys_getsizeof urandom_extra ure_groups ure_span ure_sub ure_sub_unmatched vfs_basic vfs_fat_fileio1 vfs_fat_fileio2 vfs_fat_more vfs_fat_oldproto vfs_fat_ramdisk vfs_userfs
# Debugging
The easiest way to debug CircuitPython on hardware is with a JLink device, JLinkGDBServer, and an appropriate GDB.
Instructions can be found at https://learn.adafruit.com/debugging-the-samd21-with-gdb
If using JLink, you'll need both the `JLinkGDBServer` and `arm-none-eabi-gdb` running.
Example:
JLinkGDBServer -if SWD -device ATSAMD51J19
arm-none-eabi-gdb build-metro_m4_express/firmware.elf -iex "target extended-remote :2331"
If your port/build includes `arm-none-eabi-gdb-py`, consider using it instead, as it can be used for better register
debugging with https://github.com/bnahill/PyCortexMDebug
