Other Parts Discussed in Thread: TUSB321
dear
customer bought the sample development board for TUSB542EVM, and tested it with the board. The configuration mode of the original board is DFP mode, type-b is Host, and type-C is device. Connect type-B to the computer, and type-C is connected to the U disk, and the computer can normally recognize the U disk.Namely, the positive guide (1 way into 2 ways);
What is needed is the UFP mode. After reading the TUSB321 chip manual, modify the PORT pin into the pull-down mode and the PORT pin into the UFP mode. The power supply of the original board is forward, so the jumper leads the power on.Ideally, type-C is Host. The Device is attached to the U disk, and the U disk can be identified both in forward and backward insertion.
But after making the modification, there is no response;
any advice?thanks in advance~
