Emergency bootloader for nRF52 devices #74

Open jwise opened 5 years ago

jwise commented 5 years ago

nRF52 devices will need an emergency / update bootloader. Since they have plenty of micro flash, probably the best thing to do is to give them a separate image that uses the nRF SoftDevice APIs already that always lives in micro flash and has its own Bluetooth stack, rather than a two-stage "bootloader + PRF" style solution like Pebbles used to have.

I'm doing the two-stage bootloader + PRF thing for now, because I think it'll be easier in the long run.
