Hello,

I am working with the i.MX93 to read a camera using the AP1302 ISP and the AR1335 sensor. I am using the imx-image-core, and here is my device tree:

ap1302: ap1302_mipi@3c {

compatible = "onsemi,ap1302";

#address-cells = <1>;

#size-cells = <0>;

reg = <0x3c>;

status = "okay";

sensors {

#address-cells = <1>;

#size-cells = <0>;

            onnn,model = "onnn,ar1335";

            sensor,resolution = <3840 2160>;

};

};

ports {

port@0 {

Here is my log:

root@imx93evk:~# dmesg | grep -E 'ap1302|mx8-img-md'

However, when I run the command:

The result is that the file TestPNG.png has no data.

Please help me resolve this issue.

what board do you use? nxp board or your own board? did you try the demo images?

Our company's board design is based on the I.MX93-EVK kit to use imx-image-core. Below are the adjustments I made in the project:

  • Modified the source code ap1302.c
    • Configured the control pins according to my hardware: RESET (ACTIVE LOW)
    • Removed the checksum verification line in the ap1302_fw_handler function -> Without this line, the code reports an error "checksum does not match. T:0xFFFF F: 0x0000"
  • Modified the configuration in the device tree as described above
  • I can send you our hardware schematic if needed!
