Part Number: TMS320C5517
Tool/software: TI C/C++ Compiler
Hi,
I'm trying to write some test code targeted for the C5517 and I want to use the cregister definition for the IER0 register.
After setting up my CCS project, it shows a processor setting of -v5515. I tried setting it to 5517 but it's not accepted. Then I tried for a while to figure out what -v options are acceptable, didn't find it on any documentation (and I looked through it all). Then by accident, I saw a note in the CCS Compiler settings dialog box that if you type list instead of a value, a list shows up in the title bar, not intuitive at all. I discovered I can use -vcpu:3.3. IMO this whole CPU/silicon revision input the the compiler is confusing as heck.
Anyways, the real reason I'm trying to set the proper -vcore version is I'm using c55x.h and trying to use the cregister definition for the IER0 register.
In c55x.h you have...
#ifdef __TMS320C55X_PLUS__
extern __cregister volatile unsigned long IER;
extern __cregister volatile unsigned int IER0;
extern __cregister volatile unsigned int IER1;
extern __cregister volatile unsigned long DBIER;
extern __cregister volatile unsigned int DBIER0;
extern __cregister volatile unsigned int DBIER1;
extern __cregister volatile unsigned int IVPD;
extern __cregister volatile unsigned int ST0;
extern __cregister volatile unsigned int ST1;
extern __cregister volatile unsigned int ST2;
extern __cregister volatile unsigned int ST3;
extern __cregister volatile unsigned long XSP;
extern __cregister volatile unsigned long XSSP;
extern __cregister volatile unsigned long RETA;
extern __cregister volatile unsigned long IFR;
extern __cregister volatile unsigned int IFR0;
extern __cregister volatile unsigned int IFR1;
extern __cregister volatile unsigned int BER;
extern __cregister volatile unsigned int BIOS;
extern __cregister const volatile unsigned int IIR;
extern __cregister const unsigned int CPUCFG;
extern __cregister const unsigned int CPUREV;
#endif
So, in order for these cregister definitions to be defined, the symbol __TMS320C55X_PLUS__ has to be defined. I tried defining it myself in code but then the compiler complains about it
Here's my C code. I copy/pasted the cregister definition so I didn't have to define __TMS320C55X_PLUS__. same end result as if I had defined it and included c55x.h.
//#include <c55x.h>
extern __cregister volatile unsigned int IER0;
int main(void)
{
IER0 = 0x00000001;
return 0;
}

So my question is, how do I use the cregister definitions? I tired using -vcore:3.3 and that didn't work
Thanks
