About the process of ISP

[lei11]

The development board I am using is imx8mp, and the SDK version is 6.1.22+g66e442bc7fdc.

I switched the device tree to imx8mp evk dual os08a20. dtb

When I don't do anything, that is to let the system automatically mount. ko ,can generate this data format

But when I want to load ko myself

root@imx8mpevk:~# insmod vvcam-dwe.ko
root@imx8mpevk:~# insmod vvcam-isp.ko
root@imx8mpevk:~# insmod imx8-media-dev.ko
root@imx8mpevk:~# insmod os08a20.ko
root@imx8mpevk:~# insmod vvcam-video.ko

 There can only be these three

May I ask if there is any operation I missed

[lei11]

May I ask if anyone can help me ?

use command like ./isp_media_server CAMERA0 & to start ISP then check again

Alternatively, you can provide a complete operation tutorial, such as downloading the 6.1.22+g66e442bc7fdc image from the official website and successfully burning it, as well as how to manually load KO, start ISP, and achieve the same effect as self starting




My current confusion may be that I don't know what series of operations are needed to achieve the same effect as self starting

It's blocking here

I executed the command, but only printed this one

give me full log for the ./isp_media_server CAMERA0 & to start ISP , I found you have many error on it, and for ISP document, you can find them from nxp official website, we have been released many documents for this, for os08a20, you can refer to the document
