lt6911c 龙讯的hdmi转mipi

fxy880512

      这个芯片厂家已经配置好了输出1920*1080 60fps yuv422 4lanes，上电就直接输出。
该芯片没有i2c配置，我现在是修改ov13850的驱动，去掉了i2c配置，修改输出参数，还是出不来图像。用的板子是aio-3399j。
有人这样做过没，提供下思路。

楼主，你这个LT6911搞定了没； 我现在也是在rk3399pro上按这种方式移植了，但获取帧时，rkisp中断没有触发，一直获取不到帧数据； 我用ov13850 ， media 拓扑一致， ov13850可以获取帧

我也按照楼主的方法去驱动，也是没图像显示。你们解决了这个问题了吗

fengyong

还是没有搞定，整个media topology 看起来很正常，用rkisp的测试例程就是获取不到帧数据， 同样的media topology ， 同样的测试程序，ov13850就是可以获取帧

会不会是你的ltLT6911输入的TIMING和摄像头这边的驱动TIMIG 触发不一样，配置好了输出1920*1080 60fps yuv422 4lanes。估计要查看这部分是否一致。

fengyong

好的，谢谢提醒；我查下这部分配置

bingking88

fengyong,
  有没有搞定，能否分享一下遇到同样的问题。

fengyong

to bingking88:

  前一段时间由于有其他项目任务，这个产品的功能暂缓了，这几天准备再调试。

  1.  我这边还没有调通，使用现在的方法（改造ov13850）,这个流程一直卡在rkisp获取不到中断,LT6911在csi上信号也有； 咨询过龙讯的FAE， 这个固件是他们和瑞芯微的工程师调试过的，但我们获取不到原厂的支持，驱动和dts这边不知道有啥问题，自己调试一直没搞通，这个产品一直不能出货，很是郁闷。

  2.  在网上遇到一个网友，他在rk3399 Android上调通过LT6911的，他的方式和我们现在不一样，由于rk提供的hdmiin使用的是tc358749，适配tc358749是OK的，他直接修改的tc358749驱动和ANdroid HAL层中的TC358749XBG_MIPI_YUV中代码，这个他是调通的；图像和声音都是OK的；
  

独角兽

我个人理解只要把LT6911这里调得有输出，rockchip这边的dphy驱动中把lanes_num, clk, 传输格式调成一致即可。如果连中断数据都没有，那估计时钟这块或者数据线和时钟线d+,d-接反了

xyyangkun

你们通过isp通路可以采集吗？我这边cif通路采集正常，isp通路报错。
