Build Bootloader compatible firmware for EasyL1105 MSPM0 board with Code Composer Studio

Build Bootloader compatible firmware for EasyL1105 MSPM0 board with Code Composer Studio

  designed a development kit for the recent Texas Instruments MSPM0 microcontroller series. 
In this post, I build a .HEX file that can be used with the Python bootloader for this board.
Level: very easy.

 Required hardware and software

Generate firmware in ihex format

ccstudio configures your GCC project to generate ARM ELF firmware. The bootloader expects ihex. These additional steps in the project setup build output in that format.

enable GNU ObjectCopy Utility

configere GNU ObjectCopy

  • output file name: ${PROJECT_BUILD_DIR}/${ProjName}.hex
  • format: ihex
  • flags: --gap-fill 0xFF

That's all. You now have a compatible firmware binary

Programming the kit

This is explained in  EasyL1105: A Dev Board for the TI ARM Cortex-M0+ L-Series .
Here's my command line:

python3 "C:\Users\jancu\Documents\git\git_shabaz\easyL1105\mspm0_programmer\python\mspm0_prog.py" --port COM18 C:\Users\jancu\workspace_ccstheia\EasyL1105_helloworld\Debug\helloworld.hex

Thanks for reading.

    I tried it with 6 projects, and they all worked with SWD and bootloader

    I'm trying a larger project with FreeRTOS. Still struggling to get past compile errors.
    If that one loads with the bootloader, anything will.

    disclaimer: don't know about signed firmware yet. I haven't got that working in either case.

  • Glad that Python programmer is working! It does need more testing, so if you ever come across a situation where you're getting unexpected results with it, it may be worth double-checking with the result with SWD or UniFlash etc. I dont know of any bug with the Python programmer so far, but Ive only used it for small simple programs.
