i.MX8M Plus ISP standalone

[ulrich_sorensen]

Hi,

I am trying to get the iMX8MP EVK board and Basler BCON camera to work using a differnet build system than Yocto. The camera and board works fine on Yocto ver. 5.15.5 but using Ptxdist to build a linux BSP, I cannot get the video stream to start.

On Ptxdist I have build a 5.15.5 kernel with the NXP patches to the iMX8MP. Furthermore, I have downloaded:

https://source.codeaurora.org/external/imx/isp-vvcam/tag/?h=lf-5.15.5-1.0.0
https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/isp-imx-4.2.2.17.0.bin

Using Ptxdist, I have built the vvcam kernel modules and the isp-imx software and drivers. The kernel modules and the isp_media_server and libs are copied to the iMX8MP EVK board to the designated folders (/usr/lib and /opt/imx8-isp/bin/). However since it is not working I suspect something to be wrong with my build but I have a hard time figuring out exactly what is wrong.

On target I start the media server using the script:

/opt/imx8-isp/bin/start_isp.sh

This seems to work fine and creates a media device which is like what I see on the Yocto system.

root@board:~ media-ctl -d/dev/media1 -p

That all goes well but when I run GStreamer, I get the following error.

Does anyone have an idea what may be wrong and where I should start to look.

Thanks,

sorry, Ptxdist  isn't supported officially by NXP and we don't have experience on this
