No UVC Camera and IWLWIFI about tegra-demo-distro HOT 5 CLOSED

Sounds like you need to include the needed firmware in your image, too, doesn't it? There is a linux-firmware-iwlwifi-8265 package available which might provide what you need.

Hi @madisongh, I added the command nmcli as follow. Everything seems to be OK. I have just a problem the module. Initialization take some time then usual because of the system try all ucodes from 26 to 22. For now we can close the issue.

IMAGE_INSTALL:append = " networkmanager-nmcli"

Thanks again.

Just add the needed kernel modules to your image. If you know that just those two are needed, then putting

CORE_IMAGE_EXTRA_INSTALL = "kernel-module-iwlwifi kernel-module-uvcvideo"

in your local.conf should be enough. If there are other kernel modules that you might need, you could just use

CORE_IMAGE_EXTRA_INSTALL = "kernel-modules"

to have all kernel modules included in the image.

Thanks for prompt reply. Now uvc camera is up. But iwlwifi has some error. I get the info from dmesg as follow

root@jetson-nano-devkit:~# dmesg | grep iwl

hi @madisongh,

Thanks for your great support. I also added some extra code and it seems to be OK now.

IMAGE_INSTALL:append = " linux-firmware-iwlwifi-8265"
IMAGE_INSTALL:append = " kernel-module-iwlwifi"
IMAGE_INSTALL:append = " kernel-module-iwlmvm"
IMAGE_INSTALL:append = " kernel-module-iwldvm"
IMAGE_INSTALL:append = " kernel-module-uvcvideo"

I have just one more question how to get the command nmcli. I added extra packahe as follow bot no command found nmcli.

IMAGE_INSTALL:append = " networkmanager" 
IMAGE_INSTALL:append = " modemmanager"
PACKAGECONFIG:append_pn-networkmanager = " nmcli"
