the message you got might have something to do with needing admin rights to edit. i edited on windows machine and had no issue but perhaps on linux you need to edit while root. i do not know it just when you mention "no access" to a file that can mean opening editor via "sudo" maybe?
The square IC in that board is a USB-serial chip (most likely CP2102.)
Usually when it was hit by high voltage even in a brief moment, it will be damaged and causing shortage.
BTW, the power switcher IC (5 --> 3.3V IC, the 5-pin one) may have also died.
This IC is very useful since it has the special "zero droipout" design.
On the other hand, it will also meet its instant death when power supply goes above 5.5V, even briefly.
@Anthony-Kelly You might try unplugging the omega from the dock and putting a small piece of jumper wire between the receive and transmit connectors of the connector the omega sits in (just be careful to get those and not power lines - a 1k resistor would work too, and be more tolerant of mistakes).
With the wire in place whatever you type in a serial terminal should echo back, without it the echo should stop. That would test the USB-serial distinctly from the Omega 2.
@Brad-Buskey Right now, Your showweather program is the only project I have loaded. It sure works great! I don't know about you being a newie. Not in my book. Want to add GPS, but not until I get hotspot working. I thought I did, but soon as I shut off radio in radio in router, blank screen on display. Looks like Omega2 will only send data to wireless router. Tried many other fixes. No good. A reason I want hotspot mode is to demo the project at another location like a school. BTW the Moto-G hotspot mode works fine with my Android tablet. Can't find any reference to this subject in the Community. (Except yours) Probably not really mainstream. I guess I'll just wait.
So, has there been any movement on getting the expled to actually work? I can use the gpioctl but those are on/off, cannot control the amount of color to come through. All that comes back is "Segmentation Fault".
@luz Did you remove the resistor as suggested by Ken Konrad, so as to disable the internal antenna?
No, I didn't.
Now as you mention it, I remember having read that suggestion a while ago. Sounds like a logical thing to do - but as good as the WiFi is now as-is, I feel no immediate urge to treat my Omega2 with the soldering iron ;-)
I did a test on a fresh Omega2+ and it seemed to install fine. The Editor is a relatively large package and may need a few minutes to download and install.
Make sure you are on the latest firmware by running oupgrade, and then try installing from the Console again, and if that doesn't work try following these steps:
Post some screen captures of the Console and trying to install the Editor, showing the "Please refresh the page" screen and after refreshing where it still asks to install
Login to the Omega's command line using this guide: https://docs.onion.io/omega2-docs/connecting-to-the-omega-terminal.html
Run the following commands
opkg install onion-console-editor
Run the following command and post the output:
opkg list-installed | grep onion-
Photos of the Omega connected to the Expansion Dock, and plugged into a power source (either your PC or wall outlet)
Please include one top-down photo and one from the side (showing where the Omega is connected to the Expansion Dock)
