rk3588开发板接RAW-MIPI-SC132M无法获取图片
-
模块上电后，查看触发模式是流模式，配置imgacq为1后，读取图片阻塞不动一直读取不到图片，用示波器测量lane clk pin无信号。
-
@jihua
请执行一下uname -r，把结果发上来。
另外请检查一下你移植到的板子的mipi接口的原理图，用的哪个mipi接口，几lane的。 dts需要跟原理图对应起来才行。 -
硬件接口如下：

@jihua 按照我们之前在飞凌板子上的经验，你第一个帖子上的错误提示无关的。
dts和原理图的对应关系的问题，你用的那个板子上有没有自带的支持的sensor？可作为参考。或者把之前系统自带的dts发个我对比看看。
一个终端取图，另一个终端运行一下dmesg，看看报什么错误吗？ -
取图时的信息和dmesg信息如下：

@jihua dts这么看，看不出啥问题。
你是不是有一个转接板，这个板子原理应该没问题的吧？
另外你现在接我们sc132，启动之后
dmesg | grep mvcam
dmesg | grep rkcif
发给我看一下 -
执行指令结果如下：
硬件是有转接板的，量过了线序是对应的上的：
[图片] -
@jihua
1处排线插歪了。
2处的排线没有用处建议去掉，保证mipi信号的质量。不过感觉你这个的核心问题还是
-
@veye_xumm
读取相机的datarate返回是-1代表什么意思。
-
@jihua 应该是这个版本的固件还没有支持这个寄存器。不影响正常出图和对接的。
-
@veye_xumm
内核打印的信息显示datarate是1.5G，用示波器测量不到时钟波形，只能测到数据波形，这个模块的实际datarate是多少的？现在抓图的时候，内核驱动报crc错误，怀疑是排线太长或者datarate对不上。
-
@jihua
按照1.5G配置是没问题的，我们在多个rk3588上面都调通的。
你用的排线是多长的？可否拍个照片我看看。 -
@veye_xumm
排线长度有26厘米长
[图片] -
@jihua 线长也没有很夸张。你测测摄像头这端，入口地方的3.3V供电，实际电压是多少？
-
@veye_xumm
VCC3V3 测量到是3.3V，MIPI_CK_N 时钟是固定的吗？时钟是多少的？设置帧率后这个时钟会变吗？ -
@jihua 相机是固定的1188M，3588那头设置为1500M是没问题的。
你把现在报的错发给我看看。 -
@veye_xumm
获取一张图片报错
-
@jihua 我们在rk平台没有遇到过这个问题。看ecc2这个错误提示的话，像是mipi信号劣化了。
