Where is the static variable?

Jeff Wong1

Hi,

I want to check the static variable

ui32PrevSeconds

in the following code:

int
main(void)
{
    static uint32_t ui32PrevSeconds;
    static uint32_t ui32PrevXferCount;
    static uint32_t ui32PrevUARTCount = 0;

After I load it to debugger of LaunchPad 1294, I don't find a way to show the address of the static variable. A static int variable should not in the stack, is it right? Why does the debugger not show its address and content in the "Memory Browser" window?

Thanks,

You might be encountering a problem where the compiler generates incorrect debug information for static variables declared inside a function - see https://e2e.ti.com/support/development_tools/compiler/f/343/t/335888

Try the workaround of building with compiler switch --common=off

[In the CCS Project Properties -> Build -> ARM Compiler -> Advanced Options -> Runtime Model Options -> set "Use ELF common symbols (--common)" to "off"]
