LS,
I’m trying to enable the IVC-ECHO service for the Jetson TX2.
According to the Jetson Sensor Processing Engine (SPE) Developer guide, the tegra186-aon.dtsi devicetree file needs to be modified to enable the ivc-echo code in the Linux Kernel.
The tegra186-aon.dtsi file will be compiled into one or more dtb files. The documentation does not mention what the name of the resulting dtb files are.
Once I would know the name of the dtb file(s) for the Jetson Tx2, what sequence is needed to get these file(s) on the target.
Does anybody know where I can find this information or what the dtb file names are and what the exact programming sequence is to get the dtb files on the target ?

You should be able find your system apply which dtb file by dmesg | grep -i kernel
nvidia@nvidia-desktop:~$ dmesg | grep -i kernel
