No wifi and permission denied on serial
My onion was working fine on a friend's house but when I got home the onion AP did not apear. I though that it could be some problem with wifi configuration and that I could fix it through serial but when I tried do connect the following apear:
meh:~ gabrielgiordano$ ls /dev/tty.*
meh:~ gabrielgiordano$ /dev/tty.SLAB_USBtoUART
-bash: /dev/tty.SLAB_USBtoUART: Permission denied
i think he is booting just fine. i tried to reset the onion a few times and nothing changed. I'm using the mini dock.
Sounds like you might have shut it off while it was updating causing a brick. You might need to reflash it.
Looks like you are on a Linux system trying to connect with a serial connection, right?
If yes try to connect the serial connection with sudo. So you might not get permisson denied.
I'm using a mac, but i can try on a linux later. how can I reflash? It wasn't updating. If I do a hard reset it will work?
I read somewhere that you need a ethernet expansion to reflash it but I don't have one
When you used it on a friends house you just have to adjust your local ip settings that you use the same IP Range as the Omega uses. Not seeing a device in AP mode can be because of troubles with other WiFi devices/ID's.
If it worked you don't have to re-flash ..
I do have an arduino shield and an ethernet shield for arduino. Is it possible to reflash the onion with this?
Primeiro de fazer alguma coisa como "reflash", você precisa saber o que realmente aconteceu ou que esta faltando. Poderia fazer um Factory reset (apertar o botão de reset ate 10 secundos). Assim o Omega fica como vinha da fábrica. Vai demorar um momento ate o Omega volta a trablahar (a luz do led ligado continualmente).
Depois poderia commeçar com onion.io/getstarted de novo.
Before re-flashing your system you need to find out what happened and or what is missing. To start over you could try a Factory reset (explanation that he needs to wait till Omega comes back with led continuously switched on, after pressing the reset button for about 10 seconds).
the Factory reset made it work again. thanks everybody :D
