20250609在荣品的PRO-RK3566开发板的Android13下解决串口可以执行命令但是脚本执行命令异常的问题
2025/6/9 20:54


缘起,为了跨网段推流,千辛万苦配置好了网络参数。
但是命令iptables -t filter -F tetherctrl_FORWARD可以在调试串口/DEBUG口正确执行。
一添加到自启动脚本中就出现各种异常!

/vendor/bin/autostart_test.sh


网络配置如下:
RK3566配置路由使D能PING通A
A:192.169.144.119
B:192.168.144.55
C:192.168.43.1
D:192.168.43.33

设备A和B是图传,在同一个网段,可以互相PING通。
【B和C】都接在RK3566【Android13】上。
C通过AP6256虚拟成为softAP。
D为笔记本电脑,通过softAP/以太网络共享接到C上。

现在,想让D来PING通A,改如何配置RK3566的路由表?

A的网关配置为B,D的网关配置为C。softAP通了。
但是以太网不通。
经过专家诊断:
需要执行:
iptables -t filter -F tetherctrl_FORWARD

至于执行:iptables -t filter -F tetherctrl_FORWARD的效果,

通过命令 iptables -t filter -L 可以查询到,
清除了网络规则:tetherctrl_FORWARD


经过艰难调试,后来怀疑是在shell脚本中需要使用完整的路径。
【偶然的原因,在init.rc中,发现别人都是使用完整的路径的^_】
搞定/办结问题!


【autostart_test.sh】
#!/vendor/bin/sh
echo "Forlinx::::::::::::::::::GNSS_CONFIG start!" > /dev/ttyFIQ0
echo "This is a test" > /dev/ttyFIQ0
echo $(date) > /data/date.txt
echo "Forlinx::::::::::::::::::GNSS_CONFIG end!" > /dev/ttyFIQ0
#/system/bin/rk3566_android_serial
sleep 180
/system/bin/iptables -t filter -F tetherctrl_FORWARD

/system/bin/uart2tcp
