CCS/TMS320F28377S: Serial boot loader flashing

Tool/software: Code Composer Studio

Hello,

I am using TMS320F28377S with CCS. I have written boot loader for the device , I have successfully flashed hex file through boot loader using SCI but when application address is returned from boot loader main function, code goes to the "void abort(void)" in exit.c instead of application address. Do we need to adjust PC or SP before jumping to main application from boot loader ?

I believe you will need to include the ExitBoot code which can be found in the SCI kernels.

Please see the ExitBoot function in this file: fwupgradec1toc2_start.asm
at this location C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2837xs\examples\cpu1\F2837xS_sci_flash_kernel\cpu01

This will take the return value and preform a branch or function call to the Entry Point address which is returned.

Regards,
sal

Hi sal,

Thanks, this worked for me , is there any way i can do such branching using c language.

Hi,

You can create a label at the start of your application code, include the application symbols in your project and make a function call to that symbol.

Also, you can insert inline assembly using the __asm(" "); intrinsic.
