Dp 1.2 tx subsystem init failed

Jump to solution

Plateform: XC7z035

Hello everyone,

As title, I can not initiate my dp subsystem. The SDK program would be stopped at Xil_DataAbortHandler().

Besides , I can't access the memory of  dp subsystem( BaseAddr to HighAddr).ps_mapping_mem_content.jpg

I'm sure that this is not the problem of the hardware, because when I switch to another "XC7z035", the problem remains.

Any comment would be appreciated.

I should make clear that the version of the DisplayPort TX Subsystem I used is V2.1

Problem is solved.

At beginning. I use vivado 2018.3 to generate the hdf file, and SDK version is 2019.1.

When hdf file is generated by vivado 2019.1 => I can access the memory block and dp tx subsystem initiate successfully.

On the other hand, If I use vivado 2018.3 and SDK 2018.3 => dp tx subsystem initial failed.

Regards
