optimize and TCM

Binge · ‎2023-12-03

Hi,

I'm using H723 for programming,and TCM ram is in use.when compiler optimization feature is on,code can not work.Is it not possible to use TCM while turning on optimization? or requires some setup?

Regards,

Have a look into the (linker) generated map file to see which symbols (functions/data) are linked into this RAM sections to get an idea.
And as @Tesla DeLorean mentioned find out why your app is not running.

Debug what's not working.

Determine if you've got code to move the data into the RAM.

Perhaps the optimizer keeps things in registers, or constant data in FLASH ?

If it's important, review the generated code/data. Start with the map and listing files.
