Compiler/TMS320F28379D: Interrupt not working when running from RAM.

Tool/software: TI C/C++ Compiler

Hi!

I want to run my program from RAM instead of from FLASH, but when changing the linker command file the interrupt does not work anymore. The interrupt is invoked by PWM time-based counter.

What must I do to get this to work?

I'm using Code Composer Studio v.7.

Linker command files:

- F2837xD_Headers_nonBIOS_cpu1.cmd

- 2837xD_FLASH_lnk_cpu1.cmd (excluded from build)

changed to

- 2837xD_RAM_lnk_cpu1.cmd

Look like some part of the code is not getting mapped properly. Did you check for the warning during compilation?

There is one warning: "This project contains 1 unresolved buildable linked resource(s). The project may not build as expected". The warning is there regardless of which linker command file I am using.

When I searched for a solution on the forum I found some cases on other platforms where the PIE vect table must be remapped, but I do not know how to do it on this DSC.

I found out that the interrupt is actually working fine. I was only pausing the code at random when i should have set breakpoints instead. Thank you for the help anyway!
