TMS320F280049: TMSF280049cpms on custom board

Chen,

Have you confirmed that you can connect to the device and load code?

Is the code executing? Did the code stop at some point?

Maybe your boot mode selection is incorrect.

Do you have anything connected to the PWMs? If so, disconnect it. Are they toggling now?

Yes, I confirmed connect to device and successful lode code.
But the code didn’t executed, I press the step over button to check the code whether executed, but it didn’t work.

I choose boot from flash mode ,so I connect the 3.3V on GPIO24、GPIO32 through 56k pull up resistors, this method is referring to the F280049C controlCARD layout.

I didn’t have anything connected to the PWMs.

Chen,

are you trying to run from flash, or are you trying to run from RAM? Typically customers will debug their code in RAM then move it to flash. If you want to run from flash check out the post below.

 

Have you modified the DCSM OTP locations, these can affect how the device boots.

Are you trying to run with an emulator connected?

Cody Watkin,thank for your reply!

Now I run from flash with the emulator connected (XDS2XX), and I didn’t modify DCSM OTP locations I used the default setting.

The same condition, I can load the code and executed in TMDSDOCK280049C Developer’s Kit, so I think my code and setting should be correct.

Thanks!

I think my control card layout have some mistake or neglected.

What the following two circuits? Are those two circuit necessary?

Cody,

I know the issue that I didn't change to use INTOSC.

My custom board  work properly now

Thanks for your help!!! 

Great! Feel free to start another thread if you have more questions.
