Hello,
I am using a ar0144 mipi camera in a i.MX8M Mini. I am trying take a photo but always appear de same error: "base address switching Change Err"
This is the device tree that I have used:
mipi_csi_1: mipi_csi@32e30000 {
compatible = "fsl,imx8mm-mipi-csi";
reg = <0x0 0x32e30000 0x0 0x1000>;
interrupts = <GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;
clock-frequency = <445000000>;
clocks = <&clk IMX8MM_CLK_CSI1_CORE_DIV>,
<&clk IMX8MM_CLK_CSI1_PHY_REF_DIV>,
<&clk IMX8MM_CLK_DISP_AXI_ROOT>,
<&clk IMX8MM_CLK_DISP_APB_ROOT>;
clock-names = "mipi_clk", "phy_clk", "disp_axi", "disp_apb";
bus-width = <2>;
csi-gpr = <&dispmix_gpr>;
power-domains = <&mipi_pd>;
status = "disabled";
};
ar0144_mipi1: ar0144_mipi1@20 {
status = "okay";
compatible = "onsemi,ar0144_mipi";
reg = <0x10>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_csi1>;
clocks = <&clk IMX8MM_CLK_CLKO1_DIV>;
clock-names = "csi_mclk";
assigned-clocks = <&clk IMX8MM_CLK_CLKO1_SRC>,
<&clk IMX8MM_CLK_CLKO1_DIV>;
assigned-clock-parents = <&clk IMX8MM_SYS_PLL2_500M>;
assigned-clock-rates = <0>, <20000000>;
csi_id = <0>;
rst-gpios = <&gpio5 28 GPIO_ACTIVE_HIGH>;
mclk = <27000000>;
mclk_source = <0>;
port {
ar0144_mipi1_ep: endpoint {
remote-endpoint = <&mipi1_sensor_ep>;
};
};
};
&mipi_csi_1 {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
port {
mipi1_sensor_ep: endpoint1 {
remote-endpoint = <&ar0144_mipi1_ep>;
data-lanes = <2>;
csis-hs-settle = <9>;
csis-clk-settle = <2>;
csis-wclk;
};
csi1_mipi_ep: endpoint2 {
remote-endpoint = <&csi1_ep>;
};
};
};
What is the problem when appear this error?
Is clocks problem?
Is formats problem?
I have tried the same in i.MX8M (no mini) with the same camera and the same driver. In this case, I have succeeded taking a picture.
What is the diferent between two SOMs?
Thanks for all.
Josu.
