Updating CMSIS-DAP Firmware

Because the MCB1500 is delivered ready-to-use with the latest CMSIS-DAP firmware pre-programmed, downloading firmware is normally not necessary.

CMSIS-DAP USB_ISP Button LocationShould you need to download the CMSIS-DAP firmware to the MCB1500 board:

  1. Download the new firmware file to a convenient folder on the PC you use to connect to the MCB1500 board.
  2. Unplug the MCB1500 board from your PC.
  3. Press and hold the USB_ISP button next to the CMSIS-DAP controller (LPC11U35).
  4. Connect a USB cable to the DAP port on the MCB1500.
  5. Release the USB_ISP button. Your PC should now show a new drive with the name CRP DISABLD.
  6. Open this new drive. You should see one file named firmware.bin in that drive.
  7. Delete this file and copy the new CMSIS-DAP firmware file (can be any name) into this drive.
  8. Power cycle this board.

Your CMSIS-DAP controller firmware is now updated and the CMSIS-DAP interface should be operational.
