TMS320F2800132: strange behavior when debug F2800132

Zane Wei

Part Number: TMS320F2800132

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 ?

Best Regards,

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
