IMX8M Plus SOM CSI connector – which GPIO is available for camera reset / PWDN?

[meetgandhi-eic]

Hi,

I’m trying to interface a Waveshare IMX219-120 camera using a 28-pin Basler CSI connector available on the i.MX8M Plus SOM.

The CSI data lanes, clock, and I²C pins are already identified, so we do not need help with CSI signal mapping.

We would like to confirm only the following:

• Which GPIO (if any) mapped on the 28-pin CSI connector can be used as camera RESET (XCLR) and/or PWDN?

• Please share the connector pin number and the corresponding i.MX8M Plus GPIO.

We are attaching an image of the SOM highlighting the CSI connector for reference.

Thanks in advance for your support.

That header only has i2c and csi lanes connected to it due to limited available pins. The expectation was that if additional GPIO’s were needed for a sensor that they could be exposed via an i2c to gpio expander on the camera module.
