@carlo0120 , what kernel is being built as part of your build?

If it isn't one of the ones with patches provided by this layer then you will need to create your own patches and append the relevant kernel recipe to get full support for the camera.

recipes-kernel/linux/linux-tegra_4.9.bb

@carlo0120 , thanks. There are no patches in this layer for "linux-tegra". I maintain patches for the default Yocto kernels and Intel kernels but the maintenance task becomes too great extending support to other platforms.

You may find that simply renaming existing "linux-yocto_4.9.bbappend" to "linux-tegra_4.9.bbappend" will work but as the patches haven't been created against this specific kernel source tree there are no guarantees.

I did a kernel patch but uvcvideo doesn't seem to be active. uvcvideo operation log is missing. Do you know how?

[srware]

Have you also included the necessary uvc.cfg when building the kernel? See https://github.com/IntelRealSense/meta-intel-realsense/blob/master/recipes-kernel/linux/linux-yocto/uvc.cfg

ucv.cfg Patched

I included print in the code, but it doesn't print. uvc_driver.c uvc_init() { ... printk("uvc_init\n"); ... } uvc_video.c uvc_video_enable() { ... printk("uvc_video_enable\n"); ... }
