Other Parts Discussed in Thread: C2000WARE
Tool/software:
Hello,
I've noticed that some memory sections seem to be missing in the linker file generated when importing an example project from C2000Ware.
Specifically, I imported the "empty_projects" example for the F2837xS CPU1 located at: C:\ti\c2000\C2000Ware_5_05_00_00\driverlib\f2837xs\examples\cpu1\empty_projects
When I inspect the MEMORY block in the generated linker command file, it only defines memory sections from RAMGS0 to RAMGS11.
However, according to the TMS320F2837xS datasheet, some devices in this family include additional RAM sections: RAMGS12 through RAMGS15 (from 0x00018000 to 0x0001BFFF, totaling 32KB).
My question is: If I am using a device that has these extra RAM sections and I'm starting with a C2000Ware example project, do I need to manually modify the linker file to add the RAMGS12-RAMGS15 sections myself?
Thanks for your help.
