i.MX 8M plus - How to enable gstream, rtsp server

[malikshubham19]

Hi,

We got this new EVK board with os08a20 sensor for ISP tuning and we followed the guide in AN13713.pdf document to setup and do gstream, but it's not working

1. Issue 1: We can stream after running ./tuningext server and use tuning tool but simply inputting below command, nothing comes on monitor.

Hello,

There is no module for your camera on the EVK bsp, you need build you camera driver or copy the module to kernel version.

Hi,

We have done the procedures mentioned in AN13712 8MP_ISP_OS08A20_Sensor.pdf related to building kernel, isp-imx, isp-vvcam, storing useful .dtb and .ko files to board, added Sensor0_Entry.cfg, enabled isp and camera on board step. Could you please help tell, what specifics we need to do more ?

Hello,

Are you using the 6.1.22 kernel on the BSP? then building again, since the module is not working all right in your board you have to build again.

Regards

Currently using 6.1.36. Is there any document that describes what all checks we need to do before starting tuning ? We just got the EVK and sensor board and flashed.
