Interfacing IMX219 with IMX8MM

AMBh — Tue, 02 Jan 2024 10:51:29 GMT

I do want to interface the IMX219 with IMX8MM-MINI controller but i could not able to run Gstreamer pipeline as shown in below image.

I have used IMX219 driver code available from 5.7 version of linux.

I am working on 5.4.70 version in my board.

I do concern about following kernel log:

[ 322.626279] mxc_mipi-csi 32e30000.mipi_csi: format not match

DTS Entry:

imx219_mipi: imx219_mipi@10 {

port {
imx219_mipi1_ep: endpoint {
remote-endpoint = <&mipi1_sensor_ep>;
clock-lanes = <0>;
data-lanes = <1 2>;
clock-noncontinuous;
link-frequencies = /bits/ 64 <456000000>;
};
};

&mipi_csi_1 {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
port {
mipi1_sensor_ep: endpoint@1 {
remote-endpoint = <&imx219_mipi1_ep>;
data-lanes = <1 2>;
link-frequencies = /bits/ 64 <480000000>;
csis-hs-settle = <13>;
csis-clk-settle = <2>;
csis-wclk;
};

csi1_mipi_ep: endpoint@2 {
remote-endpoint = <&csi1_ep>;
};
};
};

Can you support on this?

what format do you use? refer to the logfile, current mipi csi doesn't support the format you set, do you use RAW10 or RAW12?

Hi,

I do not get format issue now. Change format from RAW10 to RAW8 from IMX219 driver code.

But the Gstreamer pipeline is getting stucked. Camera is not opening.

yes, current mipi csi only support raw8, if you need raw10, you need add this format in the driver, you can refer to this link as below
