2.6.1 No Video Device After Orin Boot

  • Verify that the kernel driver is loaded: lsmod | grep ov5693
  • Check kernel logs: dmesg | grep -i ov5693

This issue typically arises when the driver fails to load or the device tree overlay is not applied. Figure 2 and Figure 3 provide examples of driver verification.
