SOLVED 有关veye_mvcam驱动编译的问题
-
@潘阳刚
我们没有对接过edge2板子，看起来是khadas的kernel版本不支持报错的这几个ioctl命令。
你可以参考一下khadas平台原来支持的sensor的驱动，修改一下veye_mvcam.c的代码。
——比如注掉这几个ioctl，或者以其他方式实现这个功能。 -

@veye_xumm 您好，我注释掉了有关RKMODULE_GET_CSI_DSI_INFO的case，编译通过了，我连接好相机后却没能识别到相机。我使用的是i2c-3和i2c-4。

@潘阳刚 现在显示i2c不通。
你要检查两个。- 测量一下供电是否正常。
- 我们的11脚，也就是power enable引脚，你要确认是否拉高了？ 如果没有拉高，需要修改一下dts。
-
@veye_xumm 11号引脚power enable需要多少V？我将该引脚拉高，电压表测量结果为1.8V，log显示没有检测到相机。我也检测了电源引脚，为3.3V，没有问题。
-
-
@潘阳刚 对的。我们的板子现在是3.3V标准的。i2c和power enable都是这个标准的。
-
@veye_xumm 有没有1.8V的其他图像传感器？
-
@潘阳刚 我们家的板子都是按照3.3V设计的。
-
你好，我在SC130这个摄像头驱动移植时也遇到这个问题，一开始我注释掉了有关RKMODULE_GET_CSI_DSI_INFO的case，编译通过了，但是无法出图，相机寄存器读取正常；尝试从另外一个SDK里将rk_moudle.h的RKMODULE_GET_CSI_DSI_INFO拷贝过来，进行测试目前还是不行，请问你怎么解决的？
-
@m4416202 请问取图的时候有什么报错吗？ dts是否已根据你的主板上的硬件做了调整？
