Hello,
I am trying to apply sensoray 1012 for IMX8.
I followed this guilde here to build an image:
and after for kernel driver activation:
bitbake virtual/kernel -c menuconfig
and i activate the below settings for Sensoray reccomends below with no problem:

After these setting bitbake again:

bitbake ends with this warning maybe relevent:

But drivers doesnt get loaded.
Here is the start-up output relevent with PCI and TW686x driver:

Hello @Engineering_AV ,
Greetings and Welcome to Toradex Community!
One thing you could try is to bitbake -c cleanall and resume the build. Please kindly refer to the following pages that discusses this issue in detail:
https://www.yoctoproject.org/pipermail/yocto/2015-January/023274.html
Hope this helps!
Best Regards,
Janani
Hello @saijanani.tx and thank you for your reply.

Solved some problems.
Now there is no tw686x memcpy error at start up output. And i can do
when i do modinfo

But still i cant reach sensoray 1012(i should see 8 more video input here).

No, various SoCs just share certain IP like in this case where the PCIe IP of the i.MX 6 and i.MX 8 is similar and therefore using the same driver.
Greatings,
Thanks for your answer @saijanani.tx
bitbake -c cleanall
followed by bitbake solved some of the problems. Now there is no kernel boot error about tw868x. And now i can see an output with modinfo tw686x

Pci has the right driver(tw686x) but still it doesnt work. There should be 8 mode video device.

is there any idea how can i activate this device.
Best regards, Ugur
Solved:
The problem was about pci. At sturtup press space for u-boot and
# setenv defargs 'pci=nomsi coherent_pool=128M'
# saveenv
# reset
Perfect. Thanks for your Input.
Best regards,
Jaski
