移植imx462摄像头驱动到rk3588时出现了以下的问题,不知道怎么解决,内核版本是5.10

@aike 试试这个

上面的代码编译出错,我把这里连接之后在和设备树一起编译内核,再把veyecam2m编译成veyecam2m.ko模块移植进去之后还是有问题

这个是错误截图
-
@aike 我觉得dts没问题,你可以试试把veyecam2m直接编译到内核里面,而不是独立ko的形式试试。
关于dts的逻辑关系,你可以参考这篇文章。

直接整合到内核之后没有看到update sensor info failed 的报错信息,但是没有看到isp的设备文件和拓扑接口

抓取图片也有问题


-
应该是又更近了一步,现在无论是自己基于v4l2写的程序或者是gstreamer获取信息显示的画面都是绿色的

这是什么情况呢 -
@aike 首先,我们这个模组是带有isp的,因此在dts中,isp部分都给bypass掉了。
其次,你可以先试试我们wiki上的gstreamer例子,看看能不能预览。 -
我用gitee上面的gstreamer测试工具测试的时候出现了这些问题

同时串口会打印这些

请问这个问题怎么解决 -
@aike 这个我们在其他的板卡上没有遇到过。你的板子本身没有带gstreamer吗? 或者问问板卡厂家。
-
板卡是自带gstreamer的,一直在这里卡住了,会不会是摄像头模组硬件的原因呢
-
@aike 可能性很小。你试试用这个脚本抓一下图:
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap --stream-count=100 --stream-to=nv12-1920x1080.yuv `` -
我输入了v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap --stream-count=100 --stream-to=nv12-1920x1080.yuv命令之后报这个错误

-
nv12-1920x1080.yuv里面是空的
-
@aike
你试一下将驱动中下面这个函数改成如下:static int veyecam2m_enum_frame_sizes(struct v4l2_subdev *sd, struct v4l2_subdev_pad_config *cfg, struct v4l2_subdev_frame_size_enum *fse) { VEYE_TRACE if (fse->index >= ARRAY_SIZE(supported_modes)) return -EINVAL; //if (fse->code != VEYECAM2M_MEDIA_BUS_FMT/*MEDIA_BUS_FMT_UYVY8_2X8*/) // return -EINVAL; fse->min_width = supported_modes[fse->index].width; fse->max_width = supported_modes[fse->index].width; fse->max_height = supported_modes[fse->index].height; fse->min_height = supported_modes[fse->index].height; return 0; }然后重新编译一下再测测。
-
还是一样的错误

-
@aike 我们对接rk平台的经验中,只有一个厂家的板子遇到了给你这个完全一样的问题,就是用上次帖子中的方法解决的。该问题原因是此板厂提供的linux内核,调用veyecam2m_enum_frame_sizes时没有正确的传入fse->code参数,导致参数验证失败。
如果你这个方法解决不了问题,建议打开驱动中的DEBUG_PRINTK宏定义,查找一下哪个函数返回报错了。
如果只是打开这个宏定义不够,需要你手动在这些函数返回错误的地方增加打印信息,进行查找报错处。
