iMX8m Mipi CSI - Base address switching Change Err.

We are trying to integrate Sony IMX412 camera sensor for iMX8m platform. IMX412 is a Bayer sensor and it is configured as RAW10 mode, 1280x720 15fps 2 lanes, 300Mbps/lane setting. The sensor was properly configured as per the settings. Our Linux BSP version is 4.9.51-imx-ga523a59977a6 ("coral/release-chef" branch). We changed MIPI receiver clock setting into assigned-clock-rates = <266000000>, <400000000>, <66000000>. Refer below.

 

mipi_csi_1: mipi_csi1@30a70000 {
compatible = "fsl,mxc-mipi-csi2_yav";
reg = <0x0 0x30a70000 0x0 0x1000>; /* MIPI CSI1 Controller base addr */
interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk IMX8MQ_CLK_DUMMY>,
<&clk IMX8MQ_CLK_CSI1_CORE_DIV>,
<&clk IMX8MQ_CLK_CSI1_ESC_DIV>,
<&clk IMX8MQ_CLK_CSI1_PHY_REF_DIV>;
clock-names = "clk_apb", "clk_core", "clk_esc", "clk_pxl";
assigned-clocks = <&clk IMX8MQ_CLK_CSI1_CORE_DIV>,
<&clk IMX8MQ_CLK_CSI1_PHY_REF_DIV>,
<&clk IMX8MQ_CLK_CSI1_ESC_DIV>;
assigned-clock-rates = <266000000>, <400000000>, <66000000>; 
power-domains = <&mipi_csi1_pd>;
csis-phy-reset = <&src 0x4c 7>;
phy-gpr = <&gpr 0x88>;
status = "disabled";
};

 

We used Gstreamer for video streaming but it was not rendering due to Base address switching error.

We have a few questions. @Tom Zheng igorpadykov

1. What are the scenarios for this "Base address switching Change Err."? and How to Solve this issue?

2. I disabled this Base switch address in mx6s_capture.c then I was not getting the proper image(Refer attached picture).
