It seems sync does the trick.... but I'm not sure if that's the only and shortest way.

Hi. I have noticed that many times when I boot Omega2s+ for first time, the filesystem isn't as it should be.

df-h commands gives me:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root                 6144      6144         0 100% /rom

instead of

Filesystem                Size      Used Available Use% Mounted on
/dev/root                 6.0M      6.0M         0 100% /rom

It mounts overlayfs:overlayfs:/tmp/root to / instead overlayfs:/overlay to /

Why is this happening and how to fix it? I have also connected SD card to Omega (on dev board) while turning it on, so I can later copy my files to Omega that I'm currently setting up.

I've lost many hours putting files on omega, to then later on figure out they were put on RAM instead flash, and therefore they doesn't exixt anymore.

It usualy helps if I put some files to root folder or do update and then reboot, but that is very time consuming, especially if you have a hundred Omegas to setup.

I now stumbled upon similar case, if not the same with another board. I was able to connect access point of Omega2S and open putty to run commands. After I have run command wifisetup and select option 1, link with omega broke, and I think it also rebooted. I'm not sure about all circumstances, as I didn't connect via serial port.

Then I made conection with O2S again and check ifconfig.

I noticed that there is suspecious eth0.1 interface. So I decided to run command ifconfig eth0.1 down to disable that interface.
Then I tried to run wifisetup and this time it was succesful! I managed to finish instalation of all needed software and it works like a charm.

I can't check if it's the same with one that I had problems with, as it is not on it's board anymore, but for this one it worked.

@cas How Have you managed to do that. I have same problem with CTL:TIMEOUT X no matter what USB flash I use. I have also added 22ohm resistor to D+ and D- but no difference.

@György-Farkas said in Omega2S - WiFi not working:

I'm afraid it is not possible with disabled AP on Omega2:

It is possible, because I'm already sucessfuly doing it and it keeps WifiClient on.

ifconfig ra0 down and ifconfig ra0 up to disable and enable AP.

I guess there was something wrong internaly in my Omega2S.

I have tried firstboot -y procedure before but there was no difference. Only thing I didn't checked is md5 value. There are also other Omega2S running in the roorm, but I didn't managed even to put this fault one to connect to network and AP wasn't working anyway. Other omegas also have different host names and I have disabled AP on them so they are only connected to router.

Anyhow I have now somehow managed to unsolder Omega2S and put new one there. The new one is now working perfectly.

So to answer your questions, I use custom PCB where O2S had been soldered on, and as I have checked I haven't noticed any short.

Well have updated firmware with this procedure: https://docs.onion.io/omega2-docs/manual-firmware-installation.html
So I copied last version of FW to usb and then connect usb with O2S and copy FW to /tmp/ and then I ran sysupgrade<FIRMWARE FILE NAME>

I have also tried to install firmware by pressing Reset button and then selecting option 2, but I was unsucessfull, as once it showed

ERROR: CTL:TIMEOUT X
BBB_reset
usb_control_msg: request: 0xFF, requesttype: 0x21
value 0x0 index 0x0 length 0x0

and other time it started to do an infinite loop with messages

------------[ cut here ]------------

Well after initial wifi failure I updated firmware from http://repo.onion.io/omega2/images/

So it is O2 image. I don't know if there is any separate repository for O2S. If there is, please let me know.

EDIT: I found this on this forum: "Actually, Omega2S's firmware is the same as for the Omega2 and Omega2S+ has the same firmware as Omega2S+."

Hi.
I have a problem with wifi on my Omega2S board. I've successfully got 2 boards up and running, but the third one, when I connected it for the first time, I noticed I couldn't find Omega access point to connect to. Therefore I connected it to serial port to see what is going on.

When I ran wifisetup and try to scan Wifi networks, I got an error: Scan Failed, try again. And then it seems the wifi driver just reset.

Then I read there could be problem with firmware, so I loaded lastest Omega image to usb and hook it to the board. I performed the update, but wifi still doesnt work.

I don't know what could couse this behaviour.

I have noticed also this:

How to solve this issue with wifi?

@György-Farkas Well I have tried pull down resistors, but the problem is that those pins aren't floating from the beginning, as probably the internal multiplexer does something before loading the kernel. As shown on logic analyser graph pins actually go high for around 7 sec and have 1us pulses every 25us or so, which are then detected by 74hc595. DPIO 11 doesn't have those pulses, but stays high (output state) till you don't run a scriptwhere you set the output to low on other side others - 17, 16, 15 go to floating state after that.

I then decided I will go with i2c port expander for more safe and predictable operation. MCP23008 is quiet handy as they are used in relay dock and have libraries written for it.

Hi guys.

I have connected my Omega2(+) to 74HC595 shift register, and I noticed strange behaviour during bootup sequence. There is a lot of noice for certain amunt of time on those pins, and some end up high and some low. I would need those pins to stay low till I call them to change in program. How this could be acheived and which pins to choose for output.

I have capured behavior on logic analyser:

Pins that I currently use are GPIO11, 17 and 16.

Thank you for your advice.

Hi.

Does anybody knows how to setup authentication when connecting to command line via serial interface. I would like to protect data or at least make it difficult to someone with phisical access to device to get it.

Thanks.

Try this on VirtualBox: (already compiled toolchain)
https://community.onion.io/topic/2115/onion-omega-2-cross-compiler/2

But if you want to add some libraries, there could be some difficulties to re-make it, for example I had to download files manually to dl directory, because they werent downloading through make command.

Does anyone knows how to add separate libraries like curl, without using "make" comand, as it never ends and causes errors.

I have found a simple way how to do it. Someone have made VirualBox image with all neccesarry tools needed:

Hi guys.

I would like to write some programs for Omega2 in C or C++ since it has not enough flash memory to install Node.js and js modules properly. Therefore I would like to code my program in C/C++. I have been browsing through forum and stumbled upon cross-compilation. As I understand it, it is actually ment to compile kernel, which I don't need. Also when I was following steps on the tutorial of cross-compilation, when I ran command 'make', there was an error "yynyyyyynyyyyynyyn..."

So is there some nice tutorial how to set up comiler enviroment on VMware - Ubuntu, so I could compile some C++ program that would work on Omega2.

Thanks a lot.
