TMS320F2800132: strange behavior when debug F2800132

Zane Wei

Tool/software:

Hi Team,

I test the program on F2800137, it worked well. But when the code run on F2800132(because small Flash, need open optimization). It very strange:

PWM_value should be equal 50, but equal 3. I can't why cause this, open optimization will cause wrong ?

Hi Zane,

Can you try splitting up the operations to different lines of code so you can step through and see which operation is going wrong? Also just to verify, the PWM_value remains at 3 when you step over it, correct?

Best Regards,

Delaney

Hi Delaney,

I think I find the root of this issue. It should use ((100000000.0/capCountArr[3])+0.5) rather than ((100000000/capCountArr[3])+0.5) .

Best Regards,

Zane
