STM CircleOS forum / Application address MSB

ntrf.zns · 2010-05-04 07:42:40

menu.c // line 411

Code:

            addr   = (long unsigned) (*ApplicationTable) [ -CurrentApplication ] ;
            addr &= 0x00FFFFFF;
            addr |= 0x08000000;

In .hex files with memory dump i can see that addresses inside application table are stored with modified MSB. CircleOS doesn't seem to use it anywhere. Is this application size for circle_mgr.exe or somthing else?

Hi,

Effectively, the MSB contains the size of the application in Kb. This information is written and used by the circle_mgr, and also used by CircleOS to display the memory occupation in the About page.

Thanks for info. This explains why apllication size is not displayed in my About page. I guess i broke it.
