Hi,
I am trying to use the VADC at the MX6SX SDB. (i.MX L3.14.52_1.1.0 GA)
I connected the camera input at the VADC_IN0, and I checked the signal after the C353 using the oscilloscope, and it is okay.
The imx6sx-sdb.dts says:
&vadc {
vadc_in = <0>;
csi_id = <1>;
status = "okay";
port {
vadc_ep: endpoint {
remote-endpoint = <&csi2_ep>;
};
};
};
The i.MX_Linux_Reference_Manual says:

How can I test the camera input?
Thanks.
