TMS570LC4357: How to Control the Order of Global Variables in Custom Memory Sections

Hanson liu

Tool/software:

Hi，
My goal is to ensure that global variables are placed in a specific section (e.g., .shared_data) and maintain a particular order in memory, without relying on structures, pointers, or location operators. However, using KEEP, retain, or section does not achieve this.
Any help would be greatly appreciated!

Hi Jagadish,

I placed the global variables in different sections and used the GROUP command to control their order. It works as expected, although it's a bit tedious.

Thanks,
Hanson.
