Hi everyone,
I am trying to add a MIPI sensor to my imx6 custom board. I am at the step
where I am configuring the IPU and MIPI/CSI2 interface. I am trying to
configure VC2 to CSI0 in IPU2.
In imx6dql.dtsi the mipi/csi interface is defined.
mipi_csi: mipi_csi@021dc000 { /* MIPI-CSI */
compatible = "fsl,imx6q-mipi-csi2";
reg = <0x021dc000 0x4000>;
interrupts = <0 100 0x04>, <0 101 0x04>;
clocks = <&clks IMX6QDL_CLK_HSI_TX>,
<&clks IMX6QDL_CLK_EMI_SEL>,
<&clks IMX6QDL_CLK_VIDEO_27M>;
clock-names = "dphy_clk", "pixel_clk",
"cfg_clk";
status = "disable";
};
In imx6dqscm_qwks_rev2.dts the mipi/csi is configured with IPU2(ipu_id = 1),
CSI0(csi_id = 0), VC2 (v_channel=2) and 1 lane.
&mipi_csi {
status = "okay";
ipu_id = <1>;
csi_id = <0>;
v_channel = <2>;
lanes = <1>;
};
IPU2 is also defined and configured already in imx6qdl.dtsi. My issue is that
when I read memory address 0x021dc004 (MIPI_CSI_N_LANES) I get 0x00000003,
which means there are 4 active data lanes. After looking at the rest of the
registers, everything is in reset. Any hints on why everything is in reset
and/or what I have to configure to get it out of reset?
