isp_mi_stop called after start_isp.sh

alvaro_tx — Thu, 07 Mar 2024 03:28:10 GMT

Hi, we are using the ISP in the i.MX8MP with a Sony IMX307.

When we call start_isp.sh and the ISP kernel modules are loaded, right after starting the isp_media_server, there is a "enter isp_mi_stop", where the camera cannot be launched.

Then after around one minute, the ISP and the camera starts working. It doesn't happen in all modules. Any idea on why is this?

Hi @alvaro_tx,

Did you properly stop the isp service prior calling start_isp.sh?

systemctl stop imx8-isp.service
