Getting value from a Pmem location

NeedHelp — Tue, 24 Jun 2008 03:15:25 GMT

Greetings people!

Question: How do I see what is in pmem location P:0xABCD?

I tried doing:

unsigned int ucMfrFileLen = *(__pmem unsigned int *)0xABCD;

but it doesnt compile. Im using the CodeWarriro DSP C Compiler.

It should be something pretty simple but im just a beginner n pretty lost.

Thanks for your help guys!

I can do it the long way but was wondering if you had a better way:

__pmem unsigned int * pCode;

unsigned int ucMfrTail;

pCode = (__pmem unsigned int *)CVECT_PGM_TAIL;
ucMfrTail = *pCode;

Hi,

I performed several tests but I don't think we can write this declaration on 1 line.

I will check with the compiler team.

according to my test you can write the following:

unsigned int __pmem toto : 0xABCD;

int main(void)
{
...

unsigned int *ucMfrFileLen = (unsigned int *)&toto; /* working */
