imx8qm mipi csi 接口配置 接收RGB888码流

[zhouqi]

Hi 

    我想请教一个问题，目前处于初板开发阶段，之前都是以模块形式做的开发，初次碰到这种纯接口的通信适配

    fpga获得ov2740相机的码流，并以bt1120的格式输出1080p 60fps的码流；通过转化模块 LIF‐MD6000
（由bt1120格式变成RGB888格式）变成RGB888mipi码流格式输出到 imx8qm的mipi csi接口 ，不需要spi通信提供控制，只需要识别到码流然后提供接口给应用即可

    请问我需要在驱动和设备树中做哪些修改和配置来进行适配，实现imx8qm的mipi csi接口识别读取到RGB888的1080p 60fps的码流

    硬件框架图如下，CL1_SPI画错了，没有这个线

    内核版本为Linux version 4.14.98-imx_4.14.98_2.0.0_ga (gcc version 7.3.0 (GCC))

    Any ideas for debugging or suggestions appreciated.

    Thanks

you can refer to the Table 15-2. Rx Controller Core Configuration Port Descriptions, choose the correct format you need, imx8qm mipi csi supports rgb888 directly, I don't think you need to change this in the dts file

hi joanxie

    can you give the guide document to me , my porting guide.pdf don't has any 15-2 contents.

thank you very much !

Best regards

the reference manual for imx8qm hasn't been released yet, I couldn't share with you here, if you need it, pls submit a case in the nxp official website
