Compiler problem while adding global variables

David Ilgener

Hi everybody,

i have detected some absurd behavior in my project.
In not determinated intervalls i have a repeating problem with my At89c51Re2 software.

Now i reduced the Problem to a minimum.

Anywhere in my code i add a simple global variable (like static UINT32 g_ParameterChecksum = 0;) and the following code triggered the impossible error.

static UINT8 g_DigitalByteValue = 0;

...

        g_DigitalByteValue = 0;
        if (g_DigitalByteValue != 0)
        {
                Debug_ErrorOutput("Compiler Error? @digout");
                Error_FatalError(ERROR_UNKOWN);
        }
...

when i removed the new variable it works well.

I am use code banking,funtion pointers, interupts and Uv3 (from command line).
Program Size: data=233.1 xdata=8183 const=112 code=91375
Maximum block depth: 8

i suggest that some addresses pointers are mixed up, but i does not know why.

Has somebody a hint or solution for this problem?

Thanks a lot,
David

    I dont understand why this is working well or do I miss a point

    probably you have less than 64k code and no banking.

    In AT89C51RE2 there are 3 code bank and 1 common bank with each 32K code space.
    NO, In AT89C51RE2 there is 128k of code space that can be configured as "are 3 code bank and 1 common bank"
