Simple bootloader for pycom devices to run code from SD instead of internal flash. Simply copy your project as-is to a subfolder called 'src' on the SD root. (So you end up with SD_root/src/main.py, SD_root/src/lib/yourlib.py, ... )
LED Color Codes: Dim white: booting Flashing yellow/red: SD card not found Flashing purple/red: code folder not accessible Flashing blue/red: can't execute main.py
