Hello Phil,
The board does not have a USB 2.0 PHY installed, you would need to interface one to it via the EPI ULPI interface.
We don't have a development board that we sell with USB 2.0 capability, but we do have a TI design including BOM and gerbers…
Hello JK,
Please see our TM4C High Speed reference design for some details on High Speed USB design and capability: www.ti.com/.../TIDM-TM4C129USBHS
This includes non-TI RTOS software you can reference, and the software uses 120MHz System Clock…
Hello Yogesh,
The LaunchPad is designed for quick prototyping and evaluation of our devices, but it is not ideal to base your end system design from it.
This TI Design would be a much better source for you start from, and it includes the full Altium…
Hello BP101,
USB High Speed is not that simple... you need an external High Speed USB PHY to use High Speed with the device, and then have to toggle on software that High Speed is being used.
See www.ti.com/.../TIDM-TM4C129USBHS for details.

Hello Arindam,
On the topic of devices, you would need to use a TM4C129x device to be able to do High Speed mode. The TM4C123x devices don't support that (also, for the record, the device you picked for your post title doesn't have USB at all...)

Hi Miguel
There is a reference design for USB 2.0 high speed: http://www.ti.com/tool/TIDM-TM4C129USBHS
Somebody may have a USB 3.0 PHY that supports ULPI, but ULPI only supports USB 2.0 High Speed data rate anyways so I'm not sure what benefit you…
Hello Arindam,
The TM4C1294NCPDT has integrated support for Full and Low Speed USB2.0. For High Speed USB 2.0, an external PHY is needed. So the TM4C1294NCPDT does support High Speed USB, but additional external hardware is needed for that.
Now then…
Hello Chia,
I see, this is for high speed USB 2.0 operation, okay. In that case you are right the LaunchPad wouldn't be sufficient. None of our EVM's have that functionality, only a TI Design we released to show how to properly add a ULPI PHY.
The…
Hello Sampreeth,
The schematic looks ok to me except that the VDD/VDDA supplu does not seem to have a bulk cap and overall the number of de-caps being used is less. Also as To did mention, check the quality of the solder especially when GND and VCC…
