修改nginx默认配置文件，追加如下内容

root@coolpi:/home/coolpi# vim /etc/nginx/nginx.conf

rtmp {
        server {
                listen  3588;

                application live {
                        live on;
                }
        }
}

重启nginx服务，查看端口

root@coolpi:/home/coolpi# systemctl restart nginx

感谢DSOE支持！

基于openkylin系统，搭载cutefish桌面主题，漂亮！

@etrin Suggest using a 12V/2A power adapter. USB port current up to 1A.

@etrin Please confirm the typec power adapter. Also, did the ubuntu system burn successfully ?

什么是Vue

Vue是一个开源的javascript框架，Vue.js 的目标是通过尽可能简单的API实现响应的数据绑定和组合的视图组件，Vue.js库的体积非常小的，并且不依赖其他基础库。

@3395438 确实是好芯片

@lrx 是有什么需求，需要改动uboot？

@jugg 你试下不改多指配置，编译内核再更新有无报错，能自行改内核是最好的

@花月
ov5647兼容
https://wiki.cool-pi.com/en/cm5/camera-modules

可以使用gstreamer套件调用
https://www.cool-pi.com/topic/180/coolpi-4b-support-ov5647-camera-module/20?_=1692061910394

@Jake 下载我们提供的内核源码 https://wiki.cool-pi.com/en/home/application_notes ，编译链接操作一次。

假定源码目录在/home/coolpi/kernel

sudo ln -sf /home/coolpi/kernel /lib/modules/5.10.110/build
sudo ln -sf /home/coolpi/kernel /lib/modules/5.10.110/source

@Twsuts 现在系统还是22.04？ cat /proc/interrupts | grep gpu

@jugg 所以确认你的rootfs包是不是ok的。备份与安装过程，U盘是比较重要的，质量尽量选择好的

@jugg 合并再解压。你的U盘install目录存放这些文件？把rootfs.tar.gz删了先，不可共存
