@bhanuprakash3242 which blinky.hex are you flashed? The application address must start after MBR. That is, the blinky.hex should start at 0x1000 address.

Same thing happened to me, copied a hex after uf2conv and now the dongle is lost... it just blinks red two times if button pressed

EDIT: check this issue #23 try double clicking the button it worked for me!
