Question Description：
With iM8MP, we try convert HDMI input image data translate to mipi-csi, The MIPI host reports Start of transmission error, [Lane3,Lane2,Lane1,Lane0]
- the log as below：
- the manual interrupt description
- Hardware Environment：
The HDMI camera is connected to the imx8mp mipi csi2 interface through the HDMI TO CSI adapter board (LT6911C), as shown below
IMX8MP controls LT6911C chip through I2C2 bus
- Software Environment：
1. Rootfs Ubuntu 20.04 rootfs, build from nxp yocto project
2. Kernel version 5.4.70, from Forlinx BSP
3. DTS LT6911UXC Node Configuration
&i2c2 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c2>;
status = "okay";
lt6911uxc@2b {
compatible = "lontium,lt6911uxc";
reg = <0x2b>;
status = "okay";
// 省略部分无关信息
interrupt-parent = <&gpio5>;
interrupts = <5 IRQ_TYPE_LEVEL_HIGH>;
reset-gpios = <&gpio5 4 GPIO_ACTIVE_LOW>;
plugin-det-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;
hpd-ctl-gpios = <&gpio5 5 GPIO_ACTIVE_HIGH>;
camera-module-index = <0>;
port {
hdmi2csi_lt6911_in: endpoint {
data-lanes = <1 2 3 4>;
clock-lanes = <0>;
remote-endpoint = <&hdmi2csi_csi1_ep>;
link-frequencies = /bits/ 64 <297000000>;
};
};
&mipi_csi_1 {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
port@1 {
reg = <1>;
hdmi2csi_csi1_ep: endpoint {
remote-endpoint = <&hdmi2csi_lt6911_in>;
data-lanes = <4>;
csis-hs-settle = <13>;
csis-clk-settle = <2>;
csis-wclk;
};
}
Please tell me how to solve this problem
