Accessing DNUM on a 6472

Peter Robertson

I am using v6.1.12 of the compiler (I assume that number also applies to the assembler) and it refuses to accept DNUM as a register.

I am building with the -mv=6472 option which it accepts without comment, so it should understand the processor.

cl6x -mv=6472 .\x.asm

".\x.asm", ERROR!   at line 23: [E0005] Operand #1 missing: register
                                                expected
                        mvc    DNUM,           b0

Any suggestions?

I have been forced to assemble that instruction by hand to make progress!

I just did some quick testing. I tried entering a bunch of non-existent part numbers, but I never got any messages like "invalid part". It appears that 6472 is interpreted as a 64x device, not a 64x+ device. That's why you get that error. Use -mv6400+ so the compiler knows to compile for 64x+ core.

I believe the CCSv4 project wizard will set 6740, you may want to try that.

Please ignore my suggestion. I thought you were using a 674x device and not 647x. Brad's suggestion should do the trick.
