Hi Jow,

Thank you so much for the reply. Below is my /etc/config/network file

config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config interface 'lan'
option ifname 'eth0.1 eth1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'

config interface 'wan'
option ifname 'eth0.2'
option proto 'dhcp'

config switch
option name 'eth0'
option reset '1'
option enable_vlan '1'

config switch_vlan
option device 'eth0'
option vlan '1'
option ports '0t 2 3 4 5'

config switch_vlan
option device 'eth0'
option vlan '2'
option ports '0t 1'

config switch
option name 'eth1'
option reset '1'
option enable_vlan '1'

config switch_vlan
option device 'eth1'
option vlan '1'
option ports '0 1 2 3 4 5'

Could you please tell how i can use command to check WAN and LAN link
separately using switch command.

Re: [OpenWrt-Devel] AR9344 Openwrt - LAN and WAN interface link issue

[Afkar Rafique]

Hi Jow,

Thanks a lot for the reply. I have tried the switch command but getting
failed response as below:
root@openwrt:/# swconfig dev switch0 port 1 get link
failed
root@openwrt:/# swconfig dev switch0 port 2 get link
failed
root@openwrt:/# swconfig dev switch0 port 3 get link
failed
root@openwrt:/# swconfig dev switch0 port 4 get link
failed

Do i need to change the /etc/config/network file which i share in previous
mail.


One more thing, the switch command below both are same, then how will get
to know differentiate between WAN and LAN.
WAN:
swconfig dev switch0 port 1 get link

LAN:
swconfig dev switch0 port 1 get link

Could you please guide, as I newbie to this.

Regards,
Afkar

[OpenWrt-Devel] AR9344 Openwrt - LAN and WAN interface link issue

[Afkar Rafique]

Hi,

When I connect only LAN cable and check below command on console
"cat /sys/class/net/eth0.1/carrier"
will get "1"
its correct but when we check "cat /sys/class/net/eth0.2/carrier" even the
only LAN cable is connected it returns "1" but i didn't connect the WAN
cable.

The same thing if we connect only WAN cable and check "cat
/sys/class/net/eth0.1/carrier" and "cat /sys/class/net/eth0.2/carrier" both
returns "1" . But it should not be like this.

Any help would be appreciate.

[OpenWrt-Devel] AR9344 Openwrt + check Multiple condition /etc/config/system

[Afkar Rafique]

I am working on AR9344 Openwrt. I have configured the status led based on
eth0.2 trigger in /etc/config/system

config led 'Status_led'
option name 'Status_led'
option interval '50'
option sysfs 'db120:green:status'
option default '0'
option trigger 'netdev'
option mode 'link tx rx'
option dev 'eth0.2'

I have configured GPIO16 as input. I want to check both condition as below:

if( (GPIO16 is high) &&
   (eth0.2 is high) )
{
  Status Led ON
}
else
{
  status led OFF
}

I need to check both condition to ON/OFF Status LED.

Could anyone help me to write both condition to ON/OFF Status LED.

Any help would be appreciate.

Re: [OpenWrt-Devel] How to config GPIO and read the GPIO value in OpenWRT

[Afkar Rafique]

I have configured button definition in the mach-file as below:
 .desc   = "LAN WIFI button",
.type   = EV_KEY,
.code   = KEY_LAN_WIFI_BUTTON,
.debounce_interval = DB120_KEYS_DEBOUNCE_INTERVAL,
.gpio   = DB120_GPIO_BTN_LAN_WIFI,
.active_low = 1,

and add script under file : etc/hotplug.d/button/50-buttonpress

if [ "$ACTION" = "pressed" -a "$BUTTON" = "lanwifi" ]; then
echo "255" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
else
echo "0" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
fi

In this case if i move the slide switch, it works fine but one issue is
there. When i do reset the status LED always ON. If we move slide switch
only it works i mean to say suppose now slide switch in low state means
Status LED is OFF then if i do reset the device then also the Status LED
becomes ON.

Re: [OpenWrt-Devel] How to config GPIO and read the GPIO value in OpenWRT

[Afkar Rafique]

Thanks for the reply.

I have change the script as below:

#!/bin/sh /etc/rc.common

START=19
start() {
echo in > /sys/class/gpio/gpio16/direction 2> /dev/null
echo 16 > /sys/class/gpio/export 2> /dev/null
if [ "$(cat /sys/class/gpio/gpio16/value)" == "1" ] ; then
echo "255" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
else
echo "0" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
fi
}

I need to monitor the LED on/off all the time during runtime.

During start of this script its working, but not getting how to make it
work run time.

Could you please explain how i can do it in gpio-button.

[OpenWrt-Devel] How to config GPIO and read the GPIO value in OpenWRT

[Afkar Rafique]

Hi,

I am working on AR9344 Openwrt. I need to configure the GPIO16 and read the
status of GPIO.

Based on GPIO read value, has to ON/OFF the status LED.

Could anyone please explain how i can configure and read GPIO value.

Re: [OpenWrt-Devel] How to config GPIO and read the GPIO value in OpenWRT

[Afkar Rafique]

Thanks for the reply.

i have Create /etc/init.d/buttons and written below script:

#!/bin/sh /etc/rc.common
START=19
start() {
/bin/umount /etc/config 2>/dev/null
echo out > /sys/class/gpio/gpio16/direction 2> /dev/null
echo 16 > /sys/class/gpio/export 2> /dev/null
if [ "$(cat /sys/class/gpio/gpio16/value)" == "1" ] ; then
echo "255" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
else
echo "0" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
fi
}

and restart .

chmod +x /etc/init.d/buttons
/etc/init.d/buttons enable
/etc/init.d/buttons start

Now i am able to read the GPIO 16 value 1/0 based on GPIO state, but as
above script i have written to ON/OFF the Status LED based on GPIO value,
Status LED is not getting OFF even if GPIO16 value is "0".

Can anyone please help on this

[OpenWrt-Devel] AR9344 OpenWRT LED Handling

[Afkar Rafique]

Hi Everyone,

I have configured the /etc/config/system file as below:

config led 'led_status'
option name 'STATUS'
option interval '50'
option sysfs 'db120:green:status'
option default '0'
option trigger 'netdev'
option mode 'link'
option dev 'eth0.2'

so It is working fine whenever i connect eth0.2 is UP ON the Status LED and
OFF the LED in case of  eth0.2 is down.

I need to add one more condition before checking eth0.2 UP/DOWN to handle
the Status LED.

I need to check whether "$ACTION" = "pressed" -a "$BUTTON" = "BUT_1" is
pressed or not, then will check eth0.2 UP/down.

If BUT_1 pressed and eth0.2 up --> Status LED ON otherwise OFF.

Could anyone tell how i can add Button condition in /etc/config/system file.

Regards,
Afkar

[OpenWrt-Devel] Separate Default SSID for 2.4GHz and 5GHz

[Afkar Rafique]

Hi Everyone,

I am working on AR93XX openWrt project. I have to configure the wifi0 as
2.4GHz and 5Ghz as per the selection of user. Mainly I have to add
selection in the GUI to switch between 2.4GHz and 5GHz. I have to keep two
separate default SSID for 2.4GHz and 5GHz.

Could anyone can help me that how I can keep two separate configuration and
how I can handle this in software.  I mean to say how I can thin into GUI
and can handle backend.


Thanks.
