DKMS not required for Jetson camera driver build

[QQting]

Hi guys,

I noticed you have changed the DKMS configuration to build camera driver.

tier4_automotive_hdr_camera/pkg/dkms.conf

Lines 4 to 5 in 9ebee0c

	MAKE="make -f Makefile.dkms all KERNEL_SRC_DIR=/lib/modules/$kernelver/build/"
	CLEAN="make -f Makefile.dkms clean KERNEL_SRC_DIR=/lib/modules/$kernelver/build/"

However, this change may cause compilation error on L4T R35.4.1 due to the camera driver will install generic kernel headers automatically:

Since kernel upgrades involve re-flashing the BSP image, DKMS is not needed for the camera driver.

In my new PR (2796dc9), I workaround the DKMS by removing KERNEL_SRC_DIR.

Hi @QQting, sorry for sudden message to you.

Currently I'm trying to work with Jetson AGX Orin 64GB Developerkit, but it seems like I can't get the camera work with Jetpack 6.2.1 L4T36.

I wondering that you are working with RQX-59G, may I ask how did you check to make it compatible to specific driver?

• Build and install driver without errors.
• Tier4_xxx.dtbo can successfully merged with my sysytem dtb file by using fdtoverlay.
• Reboot, check all the necessary .ko drivers are successfully loaded by checking lsmod and dmesg.
• Check video nodes are succesfully generated by typing ls /dev/video*
• Use 'v4l2-ctl' or 'gst-launch' to test camera streaming

I haven't tried JetPack 6.2.1 since our RQX-59G is currently support JetPack 6.1.
