Dp 1.4 tx subsystem init failed

Plateform: ZCU102, Vivado2019.1, SDK 2019.1

Hello everyone,

As title, I can not initiate my dp subsystem, the software I type is stuck at XDpTxSs_CfgInitialize();

On the other hand, I can not access the registers of XDpTxSs

So, how could I Initiate the DpTxSs instance(ver1.4)?

Any comment would be appreciated. Thank you.

Hello @yehuh ,

 

There is an example design for DP 1.4 TX SS on ZCU102.  Could you please try an example design first to check the issue at your end?  Also, please refer to the debugging chapter in PG299.

Hello, @kshimizu Thanks for your reply.

We tried the official example of Dp 1.4 in vivado 2018.3. And the registers of XDpTxSs is accessible.

We have faced this kind of problem 2 times.(https://forums.xilinx.com/t5/Video-and-Audio/Dp-1-2-tx-subsystem-init-failed/m-p/1178105#M35613)

So, is there something we could do to make sure that the registers of XDpTxSs are accessible?
