Omega2 I can't get serial connection
-
My Omega2 + mini Dock does not start the wifi network (it was a long time ago, I don't remember what I did to make this happen), so I'm trying to update the firmware via USB, I'm following the documentation but I can't connect to the serial port, when I run the command
screen /dev/ttyUSB0 115200the terminal has no response (yes, I pressed enter several times), after closing the terminal and running the commandsudo dmesgI have the error: cp210x ttyUSB0: failed set request 0x12 status: -110is he dead?
-
@Josinaldo-Albuquerque-Barbosa Try a factory reset this may fix the wifi issue before spending to much time on the serial matter, the procedure is here
-
I've tried, it blinks for about 30 seconds but nothing happens
-
@JBarbosa Flashing for 30 seconds (please provide the precise number of seconds) suggests the device is booting, does the LED ever stop blinking and go solid? so you would expect it to be sending data to the terminal, so there is few things I would do next. Check /dev/ttyUSB0 exists
ls -la /dev/I'm assuming it does as dmesg indicated it found the cp210.
Screen should complain if there is a permissions issue, but to be safe use sudo:
sudo screen /dev/ttyUSB0 115200I prefer to use minicom because you can change communication parameters on the fly and running multiple versions of screen on the same port doesn't complain but causes problems:
sudo minicom -D /dev/ttyUSB0I would change the USB cable, if still no luck, try using a different USB port or ideally a different computer, not all USB port are the same.
Please post some of the log, specifically unplug the USB cable, wait 10 seconds, then plug it back in wait about 20 seconds. The portion of the log I am interested in includes the unplugging and then after the end of the 20 seconds.

@crispyoz I press the reset key and turn it on, it starts flashing for 30 seconds (after 11 seconds I release the reset), it turns off and turns on remaining solid, I check the wifi connection and I can't find it.
ls -la /dev/ttyUSB0* -> crw-rw---- 1 root dialout 188, 0 mar 13 02:33 /dev/ttyUSB0
sudo screen /dev/ttyUSB0 115200 -> same result
sudo minicom -D /dev/ttyUSB0 -> same resultI have already tried another cable and on a macbook (I installed the drive but the USB was not displayed)
with this command
