购买的开发板Core-1126-JD4,烧录源码编译的固件,不能工作
购买的开发板Core-1126-JD4,烧录源码编译 rv1126_rv1109_linux_release_20211022.tgz的固件,不能工作,WIFI不能用,摄像头不能用. 你要先更新源代码，然后再编译。 我已经有同步更新并编译. cat /proc/version看一下 cat /proc/versionLinux version 4.19.111 (lvsx@tchip14) (rv1126_rv1109_linux_20211206.xml) (gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05)) #116 SMP PREEMPT Mon Dec 6 10:16:00 CST 2021

抓出的版本是这样,然后WIFI也修改了密码,连接不上,通过指令
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B

ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
Failed to initialize control interface '/var/run/wpa_supplicant'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

开发板烧录编译出来的固件
1. 用指令,WIFI不能连接工作
# vi /etc/wpa_supplicant.conf
//将 SSID 替换成WiFi名称
//将 PASSWORD 替换成 WiFi 密码
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B #WiFi wpa_supplicant 后台连接
# udhcpc -i wlan0 //WiFi 连接成功后获取 IP 地址,如下不能正常工作
2. 连接网口查看摄像头不能工作 1. https://wiki.t-firefly.com/zh_CN/CORE-1126-JD4/Devices.html#wifi请问扫描可以扫出wifi吗？这个可以通过登录 web，查看wifi 信号强度确认，一般没连接到 wifi 是没接天线。
2.请提供 dmesg log，没有log 无法分析。另外可以查看一下 vlc 能否打开流 1. 通过web的WIFI是可以连接,通过指令是不能连接,为什么?已经有连接天线.
2. vlc的数据流不是默认打开的吗,怎么打开呢,在web端是看不到摄像头,摄像头是os04A 1、根据你提出的 WiFi 问题更新了 wiki 教程
#关闭默认摄像头应用
/oem/RkLunch-stop.sh
#解锁外设设备
rfkill unblock all
killall wpa_supplicant
#修改 wpa_supplicant.conf 配置文件
vi /etc/wpa_supplicant.conf
#将 SSID 替换成WiFi名称
#将 PASSWORD 替换成 WiFi 密码
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B & #WiFi wpa_supplicant 后台连接
udhcpc -i wlan0 #WiFi 连接成功后获取 IP 地址
2、摄像头不能工作提供log和相关图片
