MicroPython and or CircuitPython for the TinyZero

[alpierce]

I'd like to get MicroPython or CircuitPython running on the TinyZero board. The first bit of info I need is about the boot loader on the TinyZero. I am hoping it is the Bossa boot loader, since I am familiar with that and already have the Bossac software for uploading binary images. I have recently started using Python a lot more and it really speeds up the development cycle. It would be a great addition to the TinyZero.

would love to see something on this!

 I was able to follow the non-uf2 installation instructions at https://learn.adafruit.com/welcome-to-circuitpython/non-uf2-installation.  To install the adafruit-circuitpython-arduino_zero-en_US-4.0.1.bin image using bossac 1.7.0 on the tinyzero board.

The board shows up as a usb drive and has worked good so far.  The repl works as well.
