It perfectly works with nRF connect SDK v2.7.0 and lower.
How to reproduce ?
On VSCode with installation of nRF Connect SDK and corresponding Toolchain, Use for example "Blinky" sample Code and compile it with nRF Connect SDK v2.8.0+
- After a successful compilation, put the control board into bootloader mode by double-clicking the "reset" button. (mini DotStar RGB light Green in bootloader mode)
- Copy the .UF2 file from the /build directory.
- Paste or drag and drop the .UF2 file into the flash drive, which will appear as a new drive named "ITSY840BOOT".
Usually Led mini dotstar led light off after flash, but this time it stay red light and red "BTLE" Led bling red.
