Omi v2.0.0 Release (Dev Kit 2)

Device: Dev Kit v2

This firmware activates the endpoints for the onboard memory for the Devkit version 2.

Note that this firmware is NOT compatible with the V1 version. Attempting to flash the firmware on a V1 kit may result in undefined behavior.

If you have the release version of the V2 Kit, then this build includes a haptic motor and speaker, which will both play on startup. Also, if you hold down the button(about 3 seconds), then the device will stop recording completely, for those who are concerned about the always on microphone. Long press again to resume. You can test out the SD card functionality when the next version of the Omi app releases, so be sure to look out for that. If not, then you are welcome to use the scripts listed in firmware/testing/ sdcard_test_files. Greater control over the haptic motors and speaker from the software side will be in a future release.

To flash:

Be sure that your Dev 2 kit is charged or plugged in.

First double click the reset button. You should see a file in your file system labeled "XIAO-SENSE." Drag the 0.9.0 bootloader into the file.

Double press the reset button again. Then drag the file "omi_v2.0.0.uf2" into the "XIAO-SENSE" file system. After a while, you should see the lights blink, followed by a speaker sound and a haptic buzz.

If the release version with the SD Card is not ready yet, then please download the current version on GitHub and setup the backend in the meantime. Have fun!
