TM4C129 USB HS reference design

Anthony Levine1

TM4C129 HS USB requires external ULPI and PHY devices. Is there a reference design showing how all this fits together? What about TivaWare support for this?

I've done a lot of work with USB on the TM4C123x, but this looks like a whole new ball game.

Thanks.

Hello Anthony,

The legacy mode of USB from TM4C123x is still applicable on TM4C129. The High Speed ULPI interface is a feature addition on top of the existing USB Core.

Thanks. Can I assume that the ULPI drivers are included in the latest TivaWare?

Hello Anthony,

Yes, the ULPI drivers for USB are there in the usb.c and usblib
