TUSB1064RNQEVM: DisplayPort does not work with TUSB1146EVM

Part Number: TUSB1064RNQEVM
Other Parts Discussed in Thread: TUSB1146EVM

Hello all,


I have connected the TUSB1064RNQEVM and the TUSB1146EVM to each other (see pictures).  This is how it is described in Figure 2 in TUSB1146EVM User's Guide. I have not changed the configuration on either board (The configuration is as they came).

Unfortunately only USB3 works, DisplayPort (DP) does not work. The screen remains dark.

I have already tried different configurations. Unfortunately this did not help. If I connect a standard USB-C dock to the TUSB1146EVM, DP and USB work. This means to me that the error is at the TUSB1064RNQEVM .

Does anyone know how to adjust the configuration on the TUSB1064RNQEVM so that DP and USB3 can be transferred?

Thanks in advance
