CCS/TMS320F28377S: TMS320F28377S

Hi,

Can you define what full-speed operation means? 
What are you observing that makes you think full-speed operation is not working?


Thank you,
Brett

Hi,

Running at full speed is to let it run directly；

In the free running situation, the pwm output I set cannot be output normally, so I judge that the crystal oscillator is not working properly.

Thanks，

Hi,

I have a question on the definition of letting it run directly (full speed).  Does it mean that you have loaded and are running code inside Code Composer Studio? 
(or are you trying to run the software standalone? - booting from flash on device power up)

Could you probe XRSn and see if you see pulses after you start to have it run full speed?

Note that I do not see anything obviously wrong in your schematics.


Thank you,
Brett

Hi,

Yes, the full speed is like what you mean,I have loaded and are running code inside Code Composer Studio.

 Thank you for confirming that the schematic is ok, I will try again now,

Then reply to you according to your request.

Thank you very much

Chen
