@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 115200
I 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/ttyUSB0
I 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.
Good luck with the presentation @luz ! Don't be nervous, just image everyone listening is naked. I'll get naked to listen, but that might be more disturbing
While OpenWrt is a single user system, you can create additional users so you don't have to disclose the root user password. You can add the user by editing /etc/passwd and /etc/shadow or you can install the useradd package:
opkg install shadow-useradd
Now add a new user named "admin", but we don't want them to have shell access:
useradd admin -d /var -M -s /bin/false -p mytemporarypassword
The password is added in cleartext so you need to change it using the command:
passwd admin
Follow the prompts to set your password then you can confirm the new user has been added as required:
cat /etc/passwd
cat /etc/shadow
Since OnionOS uses ubus via rpc we need to add the user to the rpc user list. The configuration file is /etc/config/rcpd, but you can use uci commands to add the user:
uci add rpcd login
uci set rpcd.@login[-1].username='admin'
uci set rpcd.@login[-1].password='$p$admin'
uci add_list rpcd.@login[-1].read='*'
uci add_list rpcd.@login[-1].write='*'
uci commit rpcd
The username must match the username we just created and the structure of the password field causes the rpc daemon to use the system password we just created.
The "read" and "write" fields is set to an asterisk indicating that the user will have unrestricted access, the same as the root user.
You can confirm the new user had been added using a uci command:
uci show rpcd
rpcd.@login[0]=login
rpcd.@login[0].username='root'
rpcd.@login[0].password='$p$root'
rpcd.@login[0].read='*'
rpcd.@login[0].write='*'
rpcd.@login[1]=login
rpcd.@login[1].username='admin'
rpcd.@login[1].password='$p$admin'
rpcd.@login[1].read='*'
rpcd.@login[1].write='*'
Now restart the rpc daemon:
service rpcd restart
You can now login to OnionOS with the same functionality as the root user has, but the user has no console access.
@cyberai pls try running the checkCamera.py Example Python Program and posting the command line output and screenshots of the output.
This will give us a better idea of what's going on.
