The J-Link debugger firmware may be re-loaded on the BMD-3xx-Eval by following these steps:
- Download the J-Link or mbed debugger BIN file here.
- Hold down the reset button while powering on the board.
- You should see a drive called "BOOTLOADER" appear.
- Copy J-Link binary onto this Bootloader drive. The LED should go into a "fast blink" after programming is done.
- Power-cycle the board and the LED will go back on solid with a little bit of flicker indicating USB activity.
