Hi,

sorry for "stupid" question but I am trying to understand where is the problem in asm inline for too long time:

" bset XF";

compiler (realy ASM) reports "parsing error"

any suggestion,

thanks a lot!

should it be asm(" BSET XF"); in C and bSET XF in assembly?

regards.

yes, but code

asm(" BSET XF");

forces error "parsing" from some unclear reason,

thanks in adavnce

Is this the error message:

[E0000]
parse error
BSET XF

This is because XF is not defined. Use this:

//asm ("BSET XF");
asm (" bit(ST1,#13) = #1 ");

Refe to C55x v3.x CPU Algebaic Instruction Set Reference Guide for ST1 defination. http://www.ti.com/lit/ug/swpu068e/swpu068e.pdf

Also be sure to enable -algebraic mode in Runtime Model Options.

regards.

Please quote the exact error message you are getting.

I suspect you are using the --algebraic compiler option (also known as -mg) to put the compiler in algebraic assembly mode. However, that instruction is a mnemonic assembly instruction. You must not use --algebraic when compiling a C file containing that asm statement.
