UNSOLVED GX-MIPI-IMX662 can't save fps parameter

[alex_ai]

Hi,
On my new camera GX-MIPI-IMX662 I'm trying to set fps parameter (via gx_mipi_i2c.sh from 60 to 30) and save to flash by paramsave and it is working only for current session and after restart it restored back to 60 again.

How to fix it?

@alex_ai I’ve just checked this function, and it works correctly. I suspect the issue lies in the way you’re operating it.

I recommend that you always change the FPS via the v4l2-ctl command to ensure consistency across different sessions. If you use gx_mipi_i2c.sh directly, the parameters can indeed be changed by writing to the camera registers, but the driver layer is not notified of these changes. As a result, the driver retains incorrect (outdated) values.
