I want to let two GMSL cameras connect to Xavier GroupA and run “sample_camera_multiple_gmsl” sample, but it can not work. I have already checked the first camera to connect to A0, and the second one to connect to A1 following H/W spec indication…I don’t know how to let two GMSL cameras work. Is there any limitation for “sample_camera_multiple_gmsl” sample? Thanks.
Dear SivaRamaKrishna,
My camera type and used command results are listed as below. Thanks.

Dear SivaRamaKrishna ,
Thanks for your reply.
It works!
./sample_camera_multiple_gmsl --type-a=ar0231-rccb-bae-sf3325 --selector-mask=0011
And I find some problems as below. 1. I found I can not play A1 camera only, if I enter the two commands as below. The X-window always show A0 camera video…
2. But some samples do not have “–selector-mask” parameter, how to set the multiple camera?

Dear Sir,
I run GMSL SIPL Custom Camera Capture Sample as below command, and it always failed to run on E3550. The contents are as the snapshot as below. Do you have any idea about the error? Thanks.
