In this tutorial we will be discussing how to upload the .bin file to Lpc1768 board.
To upload the .bin, no external hardware is required but board should have the secondary boot loader.

Loading USB BootLoader

If the USB Bootloader is already loaded to the board then you can skip this section.
You need a USB to Serial(UART) converter in order to get this working. The neat thing about the NXP controllers is, they come with a UART boot-loader from the factory. ExploreM3FlashMagicConnection.png

Uploading .bin File

For uploading the .bin file, secondary(USB) boot-loader needs to be flashed to the controller. Even though we put a USB boot-loader, the serial boot-loader will be still present to flash the hex files using Flash Magic.

Follow the below steps to upload the new .bin file to Explore M3 board:

  1. Connect the Explore M3 Board to system using a USB cable.
  2. Hold the USB_Boot switch.
  3. Press the Reset Switch.
  4. Release the Reset Switch.
  5. Release the USB_Boot switch.
  6. Now the board will be detected as ExploreM3.
  7. Delete the old firmware.bin file.
  8. Paste the new .bin file.
  9. Reset the Board.
  10. Now your Application code should be running on the board.
