I’ve received my Turris MOX a few days ago and I have a hard time starting it up.
At first, I’ve only had two rapid blinks at boot. I’ve flashed the sdcard myself with this procedure and now it’s seems ok https://doc.turris.cz/doc/en/howto/mox_microsd_card
But still, the MOX C (ethernet) does not show any link when plugging in a network cable. I’m not event sure if it’s a hardware related issue or a software one.
For software i can recommend “Reset Mode 6” if you have a way to connect your MOX to an existing Internet connection https://doc.turris.cz/doc/en/howto/mox_rescue_modes
(the button pressing is a bit tricky to change the mode you have to press it when the led is 3 seconds on to change to the next mode).
When powering my MOX on the lights on my E-Modul (8xEthernet) light up for a short time in order of port number, i guess C-Modul should do the same thing but this is just a guess, i don’t know for sure.
