Fork of https://github.com/conorpp/u2f-zero for a more compact phisical size.
- Dual-side load, manufacturability and bulk programming a deprioritized but manual assemble was fine.
- Smaller edge-mounted switch
- Swapped R<>B LEDs due to routing constraint.
- Upgrade UFM8UB11F16 to UFM8UB31F40 (extra flash allows all features to be enabled, more readily available).
- Switch from SimplicityStudio_v3 to SimplicityStudio_v4 (to support new chip)
(Only tested on Linux)
Install Simlicity Studio 4 and activate the free Keil license.
Set your SDK paths in Makefile, and run ./setup_device.py
This will compile and flash the setup firmware, generate and load a new certificate, then build and flash the main firmware.
