Hi,
We are trying to integrate the NVP6324 IC to Jetson TX2 NX. We made a custom carrier board and connected the NVP to CSI 4 (serial_e) and I2C-2. NVP uses 4 Virtual Channels over the CSI, so my first question is about the Video Input DTS node. The “num-channels” in this case would be 4? Is that correct?
/ {
host1x {
vi@15700000 {
num-channels = <4>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
imx390_vi_in0: endpoint {
vc-id = <0>;
port-index = <4>;
bus-width = <4>;
remote-endpoint = <&imx390_csi_out0>;
};
};
port@1 {
reg = <1>;
imx390_vi_in1: endpoint {
vc-id = <1>;
port-index = <4>;
bus-width = <4>;
remote-endpoint = <&imx390_csi_out1>;
};
};
port@2 {
reg = <2>;
imx390_vi_in2: endpoint {
vc-id = <2>;
port-index = <4>;
bus-width = <4>;
remote-endpoint = <&imx390_csi_out2>;
};
};
port@3 {
reg = <3>;
imx390_vi_in3: endpoint {
vc-id = <3>;
port-index = <4>;
bus-width = <4>;
remote-endpoint = <&imx390_csi_out3>;
};
};
};
};
About the DTS I2c node, how can I configure 4 “dev-node” (video0, video1, video2, video3) using only one i2c interface? Any idea?
Regards.
