Re: Support for Adafruit Feather #nrf52840 Sense #nrf52840
The Adafruit Sense is much like the Arduino Sense, both use the nRF52840 but use a modified bootloader. They have been designed to work with the Arduino platform.
Luckily work porting the Arduino sense version is underway (check out the pull request on the Zephyr GitHub). So far it compiles and boots, there are a few issues still to be ironed out but if you could assist it would be appreciated. It shouldn't be a huge leap to get it working on the Adafruit version.
