Hi, I've just tried to use a different MB102 and short wires as suggested some days ago: Omega2 seems to work now, so the firmware was not corrupted and I don't need to flash the firmware. The problem was probably all about the power supply. I'll try with capacitor too. Thank you all

@WereCatf
I'll try with Arduino. This situation is upsetting: without the expansion dock i can't fix Omega2

@WereCatf
Yes

Thank you all for the help

Here the log. I don't understand why lots of characters are missing in the console. (I'm working at the right baud amount).

Hi, I've just tried to connect to the Omega2 with serial connection. The problem is that the Omega seems to be in loop. I can see the booting process but after a few second, before finishing the boot, the board reboot.

I need to reset the board, do you have any ideas ?

@Mark-B
Thank you for your answer.
For the power supply i'm using a MB102 (http://www.petervis.com/Raspberry_PI/Breadboard_Power_Supply/YwRobot_Breadboard_Power_Supply.html) which should supply stable 3.3 V. However I tried also to connect the Omega2 to the arduino 3.3V Out but nothing changed...

@WereCatf
Thank you for your help
I've the FT232RL FTDI which can use 3.3 volt, so it should be ok. I'll try with it.

@WereCatf
Damn...
so there isn't t a way to reset the Omega2 without the expansion board ?

@Luciano-S.
I've read the docs but I was on mobile and I probably missed that page ! Thank you

I'll try to use serial connection tonight but i'm not confident to gain access to the Omega because the led is always On (it doesn't blink neither when I plug the power on/off).

I've found this topic @ https://community.onion.io/topic/253/unable-to-find-onion-ap-wifi-network. An user with the same problem as me solved it resetting the Omega2. Since I don't have any expansion board with the reset button, can someone confirm me that connecting the GPIO 38 to the ground will reset the Omega2 ?

Hi all
I've just receveid my Omega2 but after the firmware update it seems to have died: no AP visible and no connection in my local network. I don't have any expansion board but I would like to perform a factory reset. Is it possible via the GPIO38 "FT RST" without expansion board ? How ?
Serial connection could be an alternative solution ? I have a Usb to serial converter but the GPIO scheme is not clear. Omega2 has two USB GPIO and two serial GPIO, which ones I should use ? Thank you in advance
