@Sarika-Sharma Now TOF is detected. I have choosed pmd-tof instead of pmd-tof-liow2.
But please give solution for the following problem.
When I used J7 according to the following configuration
Hardware Setup
M0104 Connector Interposer Sensor HW ID
J7 M0135 JL Tracking (M0014 ) 2
J7 M0135 JU Hires (M0025-2 ) 3
OR
J7 M0135 JL Hires (M0025-2 ) 2
J7 M0135 JU Tracking (M0014 ) 3

ONLY , The camera which is connected to JL is working either tracking or hires.
Cameras connected to JU is not working.
When i run voxl-camera-server it gives this
WARNING: cam tracking (id 1) does not seem to be alive

------ voxl-camera-server: Started 1 of 2 cameras
