• RK3588 点亮imx586摄像头

    一.硬件原理图

    mipi摄像头硬件确认点：

    1.供电：5V，2.8V，1.2V，1.8V，reset脚（硬拉3.3，上电的时候从低到高），pwron脚外接

       3.3V。

    2,时钟：MCLKOUT是24兆时钟。

    3.4组差分mipi线。mipi的data线的波形为方波。

    二.驱动移植

    RK提供的默认sdk里面已经将支持的所有摄像头驱动都添加到了内核，所以不需要移植该驱动了。

    需确认下移植驱动对应的一些信息

    三.驱动调试

    把驱动代码和设备树文件添加进去后就可以开始调试了。

    使用i2ctool工具查看i2c5，发现有2个新的设别：0x10,0x50，猜测其中一个是senser，另一个可能是sensor的马达地址，尝试修改sensor的地址为0x10或者0x50看imx586能不能进probe函数。

    当修改imx586的地址为ox10的时候，看imx586已经进了probe函数了。

    从log可以看出imx586已经进了probe函数，但是并没有识别到sensor。

    这时候，需要确认mipi摄像头上的供电是否正常，时钟是否正常。

    经确认是sensor的一路供电没有，供电正常后可以设别到sensor。

    到了这一步，可以确认，iic设备已经可以设别到sensor了，并挂载在iic5上面。

    12. [  370.297130] mipi2-csi2 ERR1:0x10000000 (ecc2)
    13. [  370.297141] mipi2-csi2 ERR1:0x10000000 (ecc2)
    14. [  370.297154] mipi2-csi2 ERR1:0x10000000 (ecc2)

    发现一直报mipi2-csi2 ERR。

    原因：一般报这种错误为物理层解析不到mipi协议。

    排查：可能mipi4组差分线出现虚焊假焊，可能mipi插线没有整理好，也可能mipi波形不对。

    mipi data波形：为方波
