In this tutorial, we will be discussing how to upload the .bin file to Lpc2148 board.
To upload the .bin, no external hardware is required but board should have the secondary boot loader.


Generating .bin File

Check this tutoial LPC2148 Keil Setup for generating the .bin file using keil.


.Bin File Using Secondary Boot Loader

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

  11. Now your Application code should be running on the board.
