CCS/CC1312R: Is there a way to load automaticaly my custom .GEL fail without to modify original .GEL.

Hi Dimitar,

Yes, this is supported. In your target configuration (ccxml) file, simply replace the existing startup gel file with your custom one. In your custom gel file, you can use the "GEL_LoadGel()" function to then load the default GEL file.

Thanks

The $(GEL_file_dir) macro is typically used to avoid absolute paths:

The issue is when you add a custom device file to your project, e.g. a modified tm4c129encpdt.gel, which then wants to call an unmodified GEL file from the CCS installation, e.g. CortexM3_util.gel.

I wasn't able to see a way to load the unmodified GEL file in the CCS installation from the custom GEL file in the project without either:

a. Specifying the absolute path to the CCS installation in the GEL_LoadGel call.

b. Copying the unmodified GEL file from the CCS installation to the project directory with the custom device GEL file.

I know that that "GEL_LoadGel()" can load gel file, but what should i write in my .gel file, so GEL_LoadGel() to be executed automaticaly?

I could not have StartUp() function in my .gel as there is such in the default that I am going to load.

I guess another option is to define a custom macro and then use that macro in the GEL_LoadGel call:

#define GEL_STARTUP_FILE     "$(GEL_file_dir)//..//..//ti//ccs1011//ccs//ccs_base//emulation//gel//cc26x2.gel"

hotmenu LoadStartGel()
{
    GEL_LoadGel(GEL_STARTUP_FILE);
}

But the custom macro is going to have an absolute path (or close to it) so it doesn't resolve the root issue.

Yes, you are correct. This is a limitation as far as I know. Since StartUp is the only function automatically called when the file is loaded, this would cause a conflict. I'm not sure if there is good workaround for this. I'm waiting for confirmation from engineering but I'm pretty sure this is the case.
