VCU hangs when used

Hi,

I'm using the VCU in a custom board (zynq U+ 7EV). We've been using extensively the ZCU106 board to set up our embedded software as well as our PS/PL design correctly.

On our board, we try to perform the SDI Rx/Tx pass-through example. It fails (linux hangs) 2-3 seconds after it starts.

The PL instance of the VCU is the same as the ZCU106. I was wondering if there is any setting I should focus on the PS configuration?

Thanks for your help.

Re: VCU hangs when used

@sebothanks for your posting your question.  We will need some additional in order to debug this.

Based on your description this doesn't appear to be VCU issue, but rather SDI Rx directly to SDI Tx.  Can you confirm that this is correct?

It would be helpful if you could provide the following:

  1. Version of the Xilinx Tools (Vivado, PetaLinux, etc.)
  2. Boot log from your board
  3. Boot log from the ZCU106
  4. Step by step instructions along with the commands you are using to test the the SDI Pass-through

 

Also it sounds like you also tested this on the ZCU106 board, but it wasn't completely clear what kinds of results you were seeing on the ZCU106.  If you can clarify this as well, it would be useful.

Re: VCU hangs when used

hello

Our custom project is based on vcu trd example but we encouter issues when using the VCU:

  • sometimes the linux hangs or crashs just after inserting the VCU module driver
  • if the whole boot can completed, then the linux hangs with no traces beetween 3s to 1 minute if we perform an HDSDI capture and encode it: gst-launch-1.0 v4l2src device=/dev/video0 io-mode=4 ! video/x-raw,format=NV16, width=1920, height=1080 ! omxh264enc target-bitrate=20000 ! fakesink

We also observe a strange issue on a modified bitstream ==> al5e 80100000.al5e: Mcu didn't start (no ping after startup, is mcu enabled ?). The bitstream modifications didn't concern the VCU

Our Vivado release is 2018.2. All our software are build into Yocto. We don't use peta-linux

On the zcu106 we are able to perform a HDSDI capture, encode it and stream it with no issues
