[How to set static IP in eth0 and wlan0 in OPi Zero]

Hi tkaiser and martinayotte.

 

The real problem I was facing was due incorrect static IP address. I was trying to use 192.168.1.100 without /24. Doing this, nmtui automatically places /32 and the IP MASK is set to 255.255.255.255 and broadcast IP to 192.168.1.100 ( the same IP of my device).

 

Setting IP to 192.168.1.100/24, all the rest is adjusted correctly ( 255.255.255.0 and 192.168.1.255 ).

 

I did the same for wlan0 ( 192.168.1.99/24 ) and now both (eth0, wlan0) are working fine.

 

I did a test using Visual Studio with linux plugin that use SSH to communicate with OPi Zero at eth0 and all worked fine. 

 

As I intend to use wlan0 as AP to control a MQTT's network of IoTs devices, I wonder that the routing issue will be solved too.

 

Thank you all people. Your support are great!

[How to set static IP in eth0 and wlan0 in OPi Zero]

Hi Tkaiser

 

If I understood correctly,  to have static IP working in eth0, I need to disable wlan0 or set it up as AP, for example?

[How to set static IP in eth0 and wlan0 in OPi Zero]

Hi Tkaiser

 

My apologies about my misunderstanding that knowledge about Raspbian Jessie can not apply for Armbian Jessie. That is very confusing for me, as, until now, I wondered that linux was a unique thing around the world. For sure, Torvald is not happy regarding for such much "flavors" around *bian(s).

 

Anyway, I just started with a fresh uSD card with the last Armbian Jessie ( from https://dl.armbian.com/orangepizero/) and configured the wifi.

 

Both interfaces, eth0 and wlan0 are operating normally, with dynamic IP. I can ping both.

 

But, if I try to fix the IP ( manual ) on eth0, using nmtui, the OPi Zero boots normally, logging as root, the eth0 shows the IP that I configured, but, it is not responding for ping. Wlan0 continues OK ( respond to ping ).

 

Is it necessary more setup anywhere along nmtui?

 

Any help will be welcome.

 

Thanks.

[How to set static IP in eth0 and wlan0 in OPi Zero]

Hi

 

I need to set static IP in eth0 and wlan0 in my OPi Zero using ARMBIAN Jessie.

 

Googling around, I read a lot of controversial options, like edit /etc/network/interfaces and use nmtui, but, I couldn't set BOTH eth0 and wlan0 to a static IP. If I do it for eth0, wlan0 doesn't work and vice-versa.

 

One guy said that after Debian Jessie version (https://nebulousthinking.wordpress.com/2016/02/25/setting-a-static-ip-for-raspbian-jessie-in-2016/), some things changed to set up static IP. Now, from Jessie, we need to edit  /etc/ dhcpcd.conf, but, where is it ( dhcpcd.conf )?

 

Can someone instruct me about how to set static IP, please?

	}

}

Thank you.

[ARMBIAN's GCC for OPi Zero doesn't compile threads]

Hi jernej and martinayotte.

 

Yessss, apparently worked.

 

I put in Visual Studio's Project/Configuration Properties/Linker/Additional Options/-lpthread and immediately the compilation was done.

 

I don't know if all the rest is OK. 

 

I will post the results soon.

 

Thank you all.

[ARMBIAN's GCC for OPi Zero doesn't compile threads]

Hi jernej

 

The problem is that I am using Visual Studio with Linux Extension Plugin to remotely compile my program and, despite the program is compiled inside OPi Zero environment, I don't know where in VS I can modify the compiling parameters to adjust -lpthread option.

 

I am searching for how to place -lpthread option yet.

[What are you using your Orange Pi Zero for?]

I am using OPi Zero as a central controller for IoTs devices ( based in ESP8266 ).

 

It will communicate with a smartphone ( Android or iPhone ) running MQTT protocol and will distribute commands over the IoTs network.

[ARMBIAN's GCC for OPi Zero doesn't compile threads]

Hi

 

I am trying to compile a program test for my new OPi Zero that is running ARMBIAN.

 

From a Hello World program test, I am trying to create a thread that will blink the led at PA17 gpio pin, but GCC's linker complains saying that can't locate pthread_create() function. I am using pthread.h.

 

Somebody found similar issue?
