After booting from the official JETPACK 5.0.2 downloaded through the sdk manager, we want to be able to view the video simply by applying our camera device-tree or camera driver.
Creating and uploading the driver module was successful.
How can we apply our device-tree (camera dtb) to /boot/dtb/kernel_tegra194-p3668-all-p3509-0000.dtb after booting?
Hi @rlatae123
There are two ways of applying the device-tree to the board:
The first one is to modify the /boot/extlinux/extlinux.conf file as for example:
TIMEOUT 30
DEFAULT primary
MENU TITLE L4T boot options
LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
FDT /boot/dtb/kernel_tegra194-p3668-all-p3509-0000.dtb
APPEND ${cbootargs} root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=
Notice that we are adding the FDT instance. So, in general, adding the following line:
FDT <dtb path>
After doing that, reboot the board.
Another way to do that is to do a manual installation. You can find an example in the following link
Hope this help!
