issues with sdi_tx.tcl in github

Jump to solution

My customer has been working on porting over the VCU TRD from ZCU106 board to Avnet Ultrazed EV SOM. They have the SDI Rx with audio extraction working and have also figured out the build configuration for the Ultrazed EV Board with the 2018.3 VCU TRD and now can build good BOOT.BIN and image.ub files. They are now trying to test SDI Tx with audio embedding.

The attached log shows there is a problem with the https://github.com/Xilinx/device-tree-xlnx/blob/master/sdi_tx/data/sdi_tx.tcl file on line 99 where the $ports_node variable is not defined. To compile he edited a copy of the sdi_tx.tcland change $ports_node to $node.

# diff /d/VCU/device-tree-xlnx-master/sdi_tx/data/sdi_tx.tcl sdi_tx.tcl
99c99
<                       set sdi_audio_port [add_or_get_dt_node -n "port" -l sdi_audio_port -u 1 -p $ports_node]
---
>                       set sdi_audio_port [add_or_get_dt_node -n "port" -l sdi_audio_port -u 1 -p $node]

The build process is:

petalinux-build   # this build fails
cp sdi_tx.tcl build/tmp/work/plnx_zynqmp-xilinx-linux/device-tree/xilinx+gitAUTOINC+b7466bbeee-r0/git/sdi_tx/data
petalinux-build   # run build again with fixed sdi_tx.tcl

This fix allows them to compile the 2018.3 vcu_sdirxtx TRD with SDI audio, but it seems like Xilinx would need to properly fix the sdi_tx.tcl file for other designs.

Hello @roopachari 

Thank you for pointing out this issue.

Yes, this issue was observed and we have fixed this for the next release of TRD.

So test for audio over SDI are ongoing and it will be launched in the next release of TRD 2019.1.
