Part Number: TM4C1290NCPDT
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.
I think the below errata may be the reason. Please also refer to a similar post here.
In reply to Charles Tsai:
Thank you for your answer. Do you think it is necessary to tie these Pins with 1kOhm to GND or can they be left floating? We can not see the misbehavior anymore when USB0VBUS is removed from 5V.
