  IMO, it is nothing to worry about, when you updated the firmware you ssh keys changed and since old ssh keys get stored on your host machine under ~/.ssh/known_hosts, it sees a conflict and gave this warning. You can rectify this by deleting old keys, open file ~/.ssh/known_hosts with a suitable editor like vim or nano and delete the line containing old keys and try ssh again.

  @Scott-Sumner LD1117A manufactured (most probably) by UTC www.unisonic.com.tw SOT-223 The full SMD marking of a device (on a Breadboard Dock what I've seen): LD1117AG 33AQTJTE where LD1117AG : A 1A output current, G Green 33A : 3.3V output voltage, A pin code 1 GND, 2 Vout, 3 Vin Absolute Maximum DC Input Voltage 18V - recommended max. 15V Vout 3.234...3.366 @ Vin 4.75...10V, Iout 0...1000 mA Dropout Voltage max. 1.30V @ Iout 1A Built-in current limit and over temperature protection - of course. Attention! I did not measure these data. The voltage rating of the SMD capacitor at Vin pin (on the Breadboard Dock) can be less than 18V . It's an analog regulator without heatsink - so you should watch also its thermal data / power dissipation if you increase the input voltage.

  Thanks for your reply. I thought the same that 0.1.10 is more stable that previous, looked at changelog. But at first, I stucked in issue when I have to set internet connection via browser. Not always I see my ssid in the available networks list and usually type it manually. Even after that when I’m pressing configure it can freeze in this half-state. I’d prefer to set it using wifisetup over ssh or console. Also I tried to use lede repos instead of onion’s, but with it I got error relocating errors for wget and missed libencrypt.so Traceroute shows that I have access to the internet. But to be honest, I use my own extension board, but I’m not sure this is the reason. If I had the problem with it my o2 wouldn’t work. And o2 gets 3.3v of power and enough current Yep, I created ticket on onion’s helpdesk and sent them logs.

  Steven I am a bit confused on how to install your cross compiled port. Do I have to rebuild it on the Onion for it to work? The files are quite large and I would need an SD card. Is there a way to copy the node rather than building it? Let me know what I am doing wrong. Thanks

  Internet of Things (IoT) is a romantic marketing term created in recent 2-3 years. There is no criteria nor standards on the IoTs. Some will rebrand a product existed for many years (way before IoT days) as IoT to "catch the wave". However, what I can say is lots of IoTs are cheap and sub-standard in many ways. Cheap and quality go opposite ways.

  Python? All I see is a bash script? Have you added #!/bin/sh (or ash) as the first line for the script? Have you tried removing the done?

  Probably late answer but if somebody is searching like I was One of the solution is to use HC-SR04+ version (support 3.3v) I have tested it on my Omega2+ and it works fine. Or if you already have 5v version just use resistors (plenty examples on net). I played little bit with c++ using Patryk27 Omega2-GPIO library. You can check my code and compiled app at github:. I'm still playing with this script.

  Basically, instead of connecting the Omerga2's Ethernet port to a Modem, it's connected directly to a Web Server with a static IP. See attached diagram. I can connect my phone to the AP, but when I type in the web address (192.168.1.250) I get a message saying can't reach that page.

  @Serzh-Reznik said in can I webCam on Uart-USB connector?: Will the camera in the system be visible as usb device? Q (if USB webcam connected to Omega2's serial port) A NO Q (if USB webcam connected to Omega2's USB port) A Yes, will be recognized as a USB (webcam) imaging device. All subject to a suitable device driver's availability. Q if webcam's USB connecting to USB-serial dongle A NO (both are USB "end point" devices, end point device needs to talk to a USB "Host")

  The Omega2's do not have a real time clock (RTC). So at start up, they have a default time which increments until such time as a network connection has been established to the Internet. Once the Omega2 has sync'd to an NTP server, the time should be accurate per your Omega's timezone setting.

  @Alex-Wells said in Building Staging Drivers (FBTFT) [RESOLVED]: Now my only problem is that the MT7628 SPI driver won't accept transfers larger than 16 bytes at a time, but that's an issue for another day Have a look here, @wdu has a modified version of the SPI driver eliminating some of the bugs in the original.
