Re: DOPI EV200 问题汇总

现在的docker是基于ubuntu 12.04的,太旧了,能不能更新下,用16.04, 否则vscode remote 都用不了, ref https://code.visualstudio.com/docs/remote/linux

你说的问题是因为我们的镜像没有安装ssh服务,你可以进容器里面先装下ssh服务再试试能不能连接

就算安装了ssh也不行,vscode 不支持 ubuntu 12.04 作为remote linux

确实是 12.04太旧了,已经end of life, 好些Mirror也没有了

还是希望能更新到16.04,这样常用的软件都支持

docker pull cijliu/dopi-ubuntu16.04:v0.99
喜欢折腾的同学可以在这个上面迭代自己的环境,我们只提供最基础的docker镜像

不错,反正基础系统好了,其它的就可以自己根据需要apt 安装

海思的vo需要适配海思的hifb,我们配的LCD是标准的linux framebuffer设备,所以要自己在获取摄像头数据后,自己做映射到fbdev上

具体描述下操作过程,有线网口默认没有启动,需要自己启动,具体执行
ifconfig eth0 up
udhcpc -i eth0 &
然后获取到ip后执行ifconfig就能看见

WIFI下传RTSP不稳定,如果需要在WIFI下传视频,需要做以下修改:
1.更换wifi驱动文件 esp8089驱动
2.板子上CN2电压选择切换到3.3V

sensor是哪个,看现象闪烁偏色是因为线没有接稳(不能晃动),mipi是差分信号,软排线因为不是双绞,多少会有影响

@cijliu 还有一个问题就是 esp8089 3.3v驱动, reboot再挂载驱动,不成功,可能是没有初始化

esp8089不支持软启动哈,所以你reboot后esp8089还是处于之前的状态没有切回来,目前只能靠断电重启解决哈,你的摄像头现象我之前出现过,就是因为线没有固定容易导致信号干扰,可以试试把线固定住,或者换短的线比较不会出现

海思的vo需要适配海思的hifb,我们配的LCD是标准的linux framebuffer设备,所以要自己在获取摄像头数据后,自己做映射到fbdev上

后面会出,最近比较忙没时间整理文档,你可以自己尝试下,获取VI的数据后得到YUV数据,然后转RGB565格式,输出到fbdev设备

总算解决了,又是改权限,又是替换/uboot/arch/arm/cpu/armv7/hi3516ev200/hw_compressed下的源文件,总算编译出来了,还不知道能不能用,明天试试吧。另外问一下,能单独烧录uboot而不烧kernel和文件系统吗?
