# Compiler
|
|
|
|
|
|
|
|
|
|
arm-none-eabi GCC version 10.3.1 is recommended, which is the current version on Ubuntu 22.04.03 LTS.
|
|
|
|
|
Other versions may generate a flash file that is too big.
|
|
|
|
|
You can get an appropriate version from: https://developer.arm.com/downloads/-/gnu-rm

# Building
|
|
|
|
|
|
|
|
|
|
To build the firmware, you need to fetch the submodules and then run make:
|
|
|
|
|
```
|
|
|
|
|
git submodule update --init --recursive --depth=1
|
|
|
|
|
make
|
|
|
|
|
```
|
|
|
|
|
|

|
|
|
You can also easily compile this in windows (will add an example shortly) meaning you no longer have to install a linux VM on Windows.
