Camera can't work

[ekeechg]

hi,
I config a GMSL camera in Orin, the video node can be found in /dev, but when I try to get video, it report error:

log as follow:

“

and I find some error report in kernel init as follow, is it the matter?:

and here is media-ctl output:

pls. provide some suggestion for trouble shooting, Thanks.

hello ekeechg,

it looks you’re using Jetson Virtual Channel with GMSL Camera Framework.
please do have vc_id in sensor mode device tree nodes, and it must to be match with the vc-id property value you’ve set in CSI/VI nodes.

[ekeechg]

I add the “vc_id”, but no help. attachment is dts file. pls kindly help checking what is wrong.

beside that, I add some trace in kernel to find why it can’t create link.

it seems the link is bounded from the trace, but i don’t know why.

hello ekeechg,

@ekeechg

driver version 6.8.12

did you working with upstream kernel?
is it possible to based-on native Jetpack public release version for development?

[ekeechg]

No, I use jp_7.0_ea_bsp. HW is Thor.

Please contact your NVIDIA representative for related support.

Hi !
I’m encountering the same issue. Have you resolved it yet?

[JerryChang]

it looks duplicated with Topic 343171. let’s keep using the same discussion thread for supports.
