Hello Mutharasu,
The error you’re encountering, “Input/output error” in the context of attempting to connect to a Wi-Fi network using ConnMan on a Verdin iMX8M Mini board, typically indicates a problem at the hardware level or with the Wi-Fi driver’s interaction with the kernel. This can be due to several reasons, such as issues with the Wi-Fi module itself, problems with the firmware, or misconfigurations in the network settings.
To resolve this issue, you can try the following steps:
Check Wi-Fi Module and Antenna Connections: Ensure that the Wi-Fi module is properly seated on the board and that any external antennas are securely connected.
Update Firmware and Software: Make sure that your board is running the latest version of the Linux image and that the firmware for the Wi-Fi module is up to date. Updating the firmware might resolve compatibility issues or bugs that are causing the error.
Review Wi-Fi Configuration: Double-check the Wi-Fi network configuration settings, including the SSID and password. Ensure that there are no typographical errors or incorrect settings.
Examine dmesg Logs: Look into the kernel message buffer using the dmesg command to identify any relevant error messages or warnings that could provide more insight into the problem. This can help identify if there are driver issues or hardware malfunctions.
Test with a Different Network: If possible, try connecting to a different Wi-Fi network. This can help determine if the issue is specific to the network you’re trying to connect to.
Reset ConnMan Settings: Sometimes, clearing the ConnMan service’s settings can resolve connection issues. You can do this by removing the /var/lib/connman directory and restarting the ConnMan service. Please note that this will remove all network configurations, so you will need to reconfigure your network connections.
Check for Hardware Issues: If none of the above steps resolve the issue, there might be a hardware problem with the Wi-Fi module. Testing the board with a different Wi-Fi module, if available, can help confirm this.
If after following these steps the issue persists, it may require a more in-depth investigation into the specific configurations and hardware setup of your Verdin iMX8M Mini board.
