i.MX8MP EVK v4l2-ctl (v4l-utils) missing?

mihael0010 — Mon, 20 Jun 2022 12:38:00 GMT

we have i.MX 8M PLUS EVK and we are doing an image sensor driver, I flashed the sd card as follows:
1.)

DISTRO=fsl-imx-wayland MACHINE=imx8mp-lpddr4-evk source imx-setup-release.sh -b build

2.)

bitbake imx-image-full

3.)

bzcat imx-image-full-imx8mp-lpddr4-evk.wic.bz2 | sudo dd of=/dev/sdd bs=1M conv=fsync

After flashing to the SD card, the system starts normally, but when I type the command:

v4l2-ctl --list-devices

the error "v4l2-ctl: command not found" appears!

Why v4l-utils is not installed on imx-image-full?

ps*** First I put imx-image-multimedia, so after that I put imx-image-full because I thought it would help, but nothing

You can add v4l-utils by yourselves by putting following line into <yocto-bsp>/build-xwayland/conf/local.conf :

IMAGE_INSTALL_append = " v4l-utils"

Super thanks

only the syntax is:

IMAGE_INSTALL:append = " v4l-utils"
