- Open \k32l2b_msd_bootloader\projectfiles\uvision\k32l2b_bl Keil project, compile and download to FRDM-K32L2B board.
- Plug USB cable to J101(K32L2B USB).
- Hold SW3, then press RESET(SW2) , this let MCU enter MSD bootloader mode. the MSD disk will be pop up.
- Drag frdm_k32l2b_fast_0x8000.bin or frdm**_k32l2b_slow_0x8000.bin** under example_app folder to update image.

-
drag config data will programming at 0x00016000
config data:
