CCS3.1.0 problem with optimization for speed

Rem Zaslavsky

I have a timer interrupt-driven application which works fine when compiled with no optimization. But when I try to optimize for speed (any level) the interrupt is not generated and consequently the program does not run. On ething I've noted - global interrupt enable register == 0 when I try to run optimized version.

Code Composer ver. 3.1.0, floating point DSP 320c6713.

Any suggestion?

Thanks in advance.

Hi Rem,

Can you post the code here? So that the reason for GIE register remaining 0 can be pointed out.

Something in your code sets GIE = 0 during optimization and enables it during non-optimization.

Disassembly of your code might help too

Regards,

Sid

My guess is something needs to marked with the volatile keyword. Without seeing the code, nothing more can be done for this case.

Thanks and regards,
