13 Sample Code for PC-Side Application
The PC-side application is developed using VC++ 2010. The bl_command.h defines the commands used for talking with the CAN bootloader on the MCU side. The library and header file for NI-CAN 8473 are included in the project.
The can_bltest.c does all the tests for bootlader:
- Opens binary image (user application)
- Sends command to ping MCU bootloader
- Sends starting address and image size to the MCU bootloader
- Sends data of the image to the MCU bootloader
- Sends execution command to run the user application
- Sends Reset command to reset the MCU
The source code of the VC++ project can be downloaded from the following URL: http://git.ti.com/hercules_examples/hercules_examples/trees/master/Bootloaders.
