## OSX ESP firmware build notes

Use the Docker NodeMCU build: https://hub.docker.com/r/marcelstoer/nodemcu-build/

OSX: `docker run --rm -ti -v /Users/aria/code/nodemcu-firmware/:/opt/nodemcu-firmware/ marcelstoer/nodemcu-build`

# other notes

Building with default modules + debug causes luatool to fail with `'stdin:1: attempt to call field 'open' (a nil value)'` since it seems file.open isn't defined. Rebuilt with fewer modules + debug and file upload seems to work fine. Did the build... just run out of space and truncate the image?
