TM4C1290NCPDT: Problem with USB Host Mode on TM4C129x devices

Part Number: TM4C1290NCPDT

Hello all,

We have developed a board with TM4C1290NCPDT with USB Host Mode. Sometimes, when we connect a USB Stick, the processor gets very hot and resets after some time.

The same behavior is seen on the EK-TM4C1294XL Rev. D Evaluation board. The problem seems to be also in the reference design of TI.

Any suggestions how to solve this problems? We already have produced hundreds of these boards. Any help is highly appreciated.

Best regards
