This is very interesting, power cycle suggests boot device read error which is spurious. Due to a transient in the power supply as you are positing. This is a very large deployment. What is the power into the board ? Have you managed to recreate this in the lab ? As the saying goes - at scale things fail.
Without bench recreate this it would be hard to verify, are theres sources of noise around the board that can affect the SPI bus data integrity during boot ? I had this issue when using the Onion in energy monitoring devices and connecting the monitor to the Onion over an SPI bus and sharing the power supply. Occassionally when switching inductive loads, particularly LED or Fluro lamps the Onion would crash with this behaviour.
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.
