UF2 bootloader for the Striso board.
Fixed
- Longer delay after writing firmware to reduce unsafe drive removal warnings.
This also improves the user experience, it was too fast to believe something really happened, now it takes half a second and feels more realistic. - Increase disk size to accept reflashing renamed CURRENT.UF2.
Plug in the Striso board with the square button pressed to start in bootloader mode. A USB drive will appear. The current bootloader version can be found in the file INFO_UF2.TXT.
Copy the new .uf2 file to the drive to update. After updating the bootloader the Striso board firmware must be reinstalled.
