Hello,
I’m working on a custom carrier board housing a Colibri iMX8DX 1GB WB module. The end goal is to get an analog camera working using the ADV7280 through the parallel CSI interface (not MIPI CSI-2).
I couldn’t find an example for that particular usage (iMX8X + ADV7280).
Those are the relevant parts of the device tree:
&i2c1 {
clock-frequency = <100000>;
status = "okay";
adv_7280: adv7280@20 {
compatible = "adi,adv7280";

pinctrl-0 = <&pinctrl_parallel_csi>;
reset-gpios = <&lsio_gpio3 12 GPIO_ACTIVE_LOW>; // SODIMM_71
powerdown-gpios = <&lsio_gpio3 21 GPIO_ACTIVE_LOW>; // SODIMM_98
// csi_id = <0>;
mclk = <27000000>;
status = "okay";
port {
adv7280_ep: endpoint@3 {
reg = <3>; // AIN4
remote-endpoint = <¶llel_csi_ep>; // Link to parallel csi endpoint
bus-type = <5>; // Parallel
bus-width = <8>; // 8-bit
data-shift = <2>; // D2-D9 are used
vsync-active = <1>;
hsync-active = <1>;
pclk-sample = <1>;
};
};
};
};
&mipi_csi_0 {

};
&cameradev {

};
};
pinctrl_hog2 was removed from pinctrl-0 in iomuxc because SODIMM_75 was in conflict.
Here’s what I’ve got so far:
- I compiled the ADV7180 driver. It’s loaded and it found the chip via i2c.
dmesg | grep adv7gives
adv7180 1-0020: chip id 0x43 found @ 0x20 (5a810000.i2c) - Something related to the image sensor interface is also working, but then there’s a problem:

Here are are the relevant parts of the schematic:
ADV7280 side:
SoM side:
As far as I understand, the video device gets created but it is later overwritten by mxc-jpeg.
I assume there’s something missing or misconfigured in the device tree.
What can I do to get the video device working?
Thank you in advance for any help provided.
