TMS320F28388D: USB Boot rom source code

Hi Swapnil,

Siddharth who helped you earlier is probably the best person to answer this on our team, but is out of the office for the next couple of days. We'll need to wait for him to get back and answer.

I also wanted to know how all the examples seem to work properly if the driverlib hw_usb.h is incorrect?

I think it may be that the examples do not actually use that hw_usb.h file that has incorrect definitions. I'm not certain however.

Best,

Kevin

Thank you Kevin.

when I use the "usblib.lib" in my project, it contains compiled library and that library doesn't actually reference any source code provided in the C2000ware. 

Is that correct?

Swapnil 

Hi Swapnil,

Yes, that seems right. The USB library source files (i.e. for usblib.lib) are actually provided in the C2000WARE directory below and I don't see 'hw_usb.h' included in them.

C:\ti\c2000\C2000Ware_4_00_00_00\libraries\communications\usb\f2838x

Best,

Kevin

Hi,

But wouldn't hw_usb.h be required to build the usblib.lib?

The source included for usblib.lib call for "usb.h" which calls for "hw_usb.h". 

Is usblib.lib included in C2000Ware build using different source code?

Hi Swapnil,

You're right, I had missed that "hw_usb.h" is included, or indirectly included, in some files. I think we'll need to wait for Siddharth to return and comment since he's more familiar with the SW library and examples. Thank you for your patience.

Best,

Kevin

Swapnil, 

Don't think the registers whose offset are incorrect are referenced by the usb lib or examples. Will take a look at it again and keep you posted.

Best Regards

Siddharth
