荔枝派zero开发板使用的是BSP Linux 配置dvp的ov2640

学习 · 2019-08-01 13:12:14

系统已经按照教程 http://zero.lichee.pro/%E7%B3%BB%E7%BB%9F%E5%BC%80%E5%8F%91/bsp_cam.html#bsp 配置了，但是上电没注册，
尝试修改了几次sys_config.fex 文件都不能注册到设备，恳求有相关经验的大佬指点一下！
下面是启动信息

我连vfe启动信息都没有打印出来

yuliang_8 · 2019-09-02 23:06:09

这个问题，我这边也之前花了点时间搞这个，我配置DVP也正确，fex文件也正确，就是始终无法读取到I2C的数据， CCI接口的问题、
但是现在看到有老兄，在主线内核里面，搞定了。就没再弄。

怀疑是BSP 内核的寄存器配置不正确，哪个出来帮忙指点一下？
谢谢

jimmy · 2019-09-03 00:02:58

据说 bsp linux 摄像头驱动程序的 i2c 那组口没有初始化。

yuliang_8 · 2019-09-05 23:14:10

6楼的老兄，具体点拨一下，怎么没有初始化？
谢谢

nothing · 2019-09-11 10:16:12

DVP和LCD公用了引脚，BSP内的引脚默认配置成LCD，要使用DVP得自己进行引脚初始化，fex配了没有相关代码进行初始化，不信在linux下直接读相关寄存器就知道了，然后ov2640的寄存器得自己调下，不然拍出来的效果是很暗的

只要把 ov2640.c 里面把引脚的 lcd 复用改为 dvp 就可以了吗？

具体查看寄存器手册对应的几个寄存器，对比下值，之前我们做V3S的方案有遇到这个问题

“要使用DVP得自己进行引脚初始化，fex配了没有相关代码进行初始化”，这句话，我能理解为 1. 自己要在fex分配dvp引脚。 2. 请问第二句“fex配了没有相关代码进行初始化”怎么在理解，麻烦解释下。

fex本质上就是一个config文件，驱动在初始化的时候会去读这个文件，解析对应的管脚进行寄存器配置，具体见fetch_config函数，里面只配置了fex里面的部分引脚，对着fex配置内容进行代码阅读就知道了

但是从fswebcam的时候，提示 [VFE_WARN]v4l2 sub device queryctrl (null) unsuccess!。但是我能通过逻辑分析仪和示波器，能抓取到大量的iic初始化数据，mclk，pclk，hs，vs信号。应该说fex配置和时初始化是成功的。麻烦指点下，感谢感谢。

晕哥，我做了转接板，打算试试ov2640 ，也买了个ov2640的镜头。今天回试试的。试了回复哈。

晕哥，我做了转接板，打算试试ov2640 ，也买了个ov2640的镜头。今天回试试的。试了回复哈。

可以直接用荔枝派zero 的板子，然后用荔枝派的固件: wifi_audio_cam_serial_zero.rar

这个应该是没有一问题的。

接着自己编译默认的ov2640.ko, 发现肯定不行。

如果你能把 ov2640 改好, 说明gc0312也是一样的套路。

如果改不好，就用这个馊主意:
把自己编译ov2640.ko 和荔枝派上面固件里面的 ov2640.ko 都用 IDA 反编译成 asm 文件,
因为用的是同样的编译器，所以编译出来都是大同小异，直接用对比软件比较 asm, 就大概会知道需要修改哪些地方。

晕哥 · 2019-09-18 14:48:26

我看了逻辑分析仪抓的图， I2C 有信号， GC0312也有输出，可能存在的问题:

1. V3s soc里面dvp接受的信号格式与GC0312输出不一致, 比如 HSYNC/VSYNC 电平/沿触发不一致

2. V3s dvp 引脚复用状态不对，是不是强行设置一波?或者用 devmem 输出对应寄存器值，对照datasheet看下复用状态？

3. 还没想到

麻烦帮我看看楼上的log信息和提示信息，指点下，多谢多谢

cci对应的引脚log上面有初始化，但是dvp对应的引脚csi没有log输出，上面有说，直接查看对应的几个寄存器，看下是不是被配置成LCD去了，寄存器PIN复用说明如下图

@nothing,
@太一酱鸭, 感谢几位大神，
感谢晕哥，都辛苦了。

真是太牛逼了，比原厂的人都厉害。

我之前也是到配置寄存器后，就无法读取数据。

谢谢各位大佬，因为之前调不出来就换了mipi接口的摄像头，后来就没有再去弄v3s了，特别感谢版主大人，特意联系我，告诉我有人解决了

你好，问一下，你mipi摄像头用的是自带的源码驱动吗？可行吗？

最新的主线-5.2版本内核，在licheepi-zero板上，接这个ov2640摄像头，确认是可以采集到图像的。

现在这个ov2640 停产了。我现在用GC0312，加载的是3.4内核自带的驱动。拍出来是一张全绿色的图片。
