| How To Compile Micropython + SoftUART for ESP8266 | |
| The build process for micropython is incredibly poorly documented all over the web, | |
| often suggesting you try to coax many years-old toolchains out of retirement. | |
| Here's how to do it simply, cleanly and (I hope!) correctly: | |
| 1. Install VirtualBox | |
| 2. Install Ubuntu 22.04.1 LTS minimal as a Virtualbox guest. | |
| Other version will likely work, but this is what I used. | |
| 20GB hard drive should be enough space (assuming minimal) | |
| 3. Enable SSH during installation and use PuTTY to log in... | |
| sudo apt update | |
| sudo apt -y full-upgrade | |
| sudo apt install git docker.io make | |
| sudo usermod -a -G docker $USER | |
| reboot | |
| 4. Use PuTTY to log back in... | |
| git clone https://github.com/micropython/micropython-lib | |
| git clone https://github.com/micropython/micropython | |
| cd micropython | |
| git checkout tags/v1.19.1 | |
| wget -q -O - https://github.com/micropython/micropython/pull/7784.diff | patch -p1 | |
| make -C ports/esp8266 submodules | |
| docker run --rm -v $HOME:$HOME -u $UID -w $PWD larsks/esp-open-sdk make -j 4 -C mpy-cross | |
| git submodule update --init | |
| cd ports/esp8266 | |
| docker run --rm -v $HOME:$HOME -u $UID -w $PWD larsks/esp-open-sdk make -j 4 | |
| ls -l build-GENERIC/combined-firmware.bin | |
| 5. Use WinSCP to copy ~/micropython/ports/esp8266/build-GENERIC/combined-firmware.bin |
