CCS/DRV8350H-EVM: Getting USB interfaces loaded on new board based upon DRV8350H EVM board design.

Part Number: DRV8350H-EVM
Other Parts Discussed in Thread: MSP430F5529, MSP430F5528, DRV8350, MSP-GANG, UNIFLASH, MSP-FET

Tool/software: Code Composer Studio

Have fabbed a board based upon the DRV8350H-EVM adding an interface, the usb shows up only as:

"T:  Bus=03 Lev=01 Prnt=01 Port=10 Cnt=01 Dev#= 62 Spd=12   MxCh= 4
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0451 ProdID=2046 Rev= 1.25
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
I:* If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=255ms
" 

How do I get the usb interface for tools and downloads, as well as the "Product=MSP430-USB Example" interfaces loaded?

T:  Bus=03 Lev=02 Prnt=40 Port=01 Cnt=02 Dev#= 45 Spd=12   MxCh= 0

    Gary,

    Have uploaded from TI's DRV8350H-EVM the EZFETLITE, downloaded to our board, talks to CCS but gets same error as above: "MSP430:  Error initializing emulator:  Could not set device Vcc" from the Code Composer Studio.  We must have hardware issue with our new board.

    Also, noted that in the 0x1900 area, don't get all downloaded: from txt file:

    0x1970:  FF FF FF FF FF FF FF FF FF FF 26 46 EF BE EF BE  
    00 10 02 00 09 00 09 00 FF FF FF FF FF FF FF FF  
    FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF  

    but read back after download:

    0x1970: FF FF FF FF FF FF FF FF FF FF 26 46 EF BE EF BE
    FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
    also difference at

    0x19f0: FF FF FF FF FF FF FF FF FF FF DA 57 DC AC DC AC
    vs

    0x19F0:  FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
    I think we are close.

    Where can we find the EZFETLITE source to assist in chasing down our issue?

    Great progress, Gary.  Thanks for the assistance.  Joe

    By default download the info memory is not allowed, you should change some settings in the GUI like Lite FET-pro430. Have you do the settings?

    Gary,  Downloaded 5529 image from an original ti 8350EVM board, connected an emulator directly to the MSP430F5529(cut two traces & tied in RST and TEST) bypassing the on-board 5528 with ezFETLITE firmware.  Couldn't get around the error from CCS as above, but CCS is now talking directly to 5529 via emulator.  Problem not resolved, but work-around in place.

    Let's close this out.

    Thanks for all the help.

    Regards,   Joe
