TMS320F28388D: USB Code Migration from 379D

Ed Sanders

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Greetings,

                We are migrating from the 379D to the 388 family (currently using the controlCARD on a baseboard.. I have SPRACQ1 which provides information on migrating between these two series of parts.  It indicates that both parts have a Type 0 USB.  So I changed the base address of the USB, but it didn’t work.  Upon examining the register sets, I realized that they are very different, and the code from the 379D would not be able to work.  Is there a document which provides details on the USB conversion?

Thank you,

Ed

    Ed, 

    The USB is the same on both these devices.  Following are the points that you need to consider during the migration

    1. You can take a look at the pinmux to see if the USB pins are configured correctly.

    2. USB CLK  - The USB is cloced by AUXPLLCLK and it has to be configured to 60MHz.  Based on the frequency that you are running on F28388D , this might require a change.

    3. If you are using the USB Library within C2000Ware, then you can use the one for F28388D located at <C2000Ware>0\libraries\communications\usb\f2838x\lib

    Best Regards

    Hi Siddharth,

                    Thanks for your help.  I found the problem.  I am using the same pin-mux as we used in the 379D, but the code which does the initialization was not there.  After adding it, the USB connected!  Thanks again!
