Problems in detecting MINISASTOCSI in i.mx8mp plus evk board

kenizgandhi — Mon, 31 May 2021 09:55:28 GMT

Hello, I am using i.mx8m plus evk board. I have connected minisastosci to my board in mipi-csi1. But when I list my devices, I am getting the following output:

root@imx8mpevk:/dev# v4l2-ctl --list-devices

mxc-isi-m2m (platform:32e00000.isi:m2m_devic): /dev/video0

This is the output I am getting after I type the below command :

root@imx8mpevk:/dev# v4l2-ctl --all -d 0

Hi KENIZ

from log "Unable to handle kernel NULL pointer dereference" reason may be in wrong image.

One can reprogram image using Demo Image from link

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applications-processors:IMXLINUX?tab=In-Depth_Tab

use guidelines included in Linux Guide.

Best regards
