IMX8MP camera output of size zero

rajtend — Thu, 27 Feb 2025 13:01:16 GMT

Hi,

I have a Phytec SoM: https://www.phytec.de/produkte/system-on-modules/phycore-imx-8m-plus/.

And I am using this version of NXP BSP:
https://www.phytec.de/bsp-download/?bsp=BSP-Yocto-NXP-i.MX8MP-PD23.1.0

I am trying to set a custom camera which is connected to CSI0 port of my board having imx.8mp. The camera is connected via LVDS to MIPI bridge and I2C of the bridge is currently programmed by a MicroController. I don;t need I2C for the moment.

I have adapted following sensor driver to suit my needs:
https://download.phytec.de/ImageProcessing/phyBOARD-Pollux-i.MX8MP_linux_PD21.1.1/VM-017/ar052x.c

I have checked using Scope, and I see the MIPI CSI signals on the pins.

I am trying to capture a single frame from camera, but the command remains stuck and the output file is of zero bytes

v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RGB24 # This command remains stuck and can be terminated by ^C v4l2-ctl -d /dev/video0 --stream-mmap --stream-to=/tmp/capture.raw --stream-count=1

I see the micro-controller output which programs the bridge:
