Hello,
I’m sorry to hear about the difficulties you’re experiencing with enabling Bluetooth and WiFi on your i.MX95-19x19 Verdin board using Yocto. Let’s go through some steps that might help resolve this issue:
-
Kernel Support Verification: Ensure that your kernel configuration includes support for the specific WiFi and Bluetooth hardware on your board. This means checking that necessary kernel modules, such as
ath11kfor WiFi and possiblybtusborhci_uartfor Bluetooth, are included in your build. -
Firmware and Drivers: Confirm that the correct firmware files are present in the
/lib/firmwaredirectory. Missing firmware can prevent the hardware from initializing properly. -
Device Tree Configuration: Verify that the device tree accurately describes the WiFi and Bluetooth hardware. Incorrect or missing entries can lead to the system not recognizing the hardware.
-
Interface Listing: Use commands like
ifconfig -aorip linkto list all network interfaces andhciconfigfor Bluetooth interfaces. This will help determine if the system recognizes the interfaces. -
Connection Management:
- For WiFi, ensure that
connmanorwpa_supplicantis installed and configured correctly to manage connections. - For Bluetooth, use
bluetoothctlto manage devices, ensuring the Bluetooth service is active and the device is discoverable.
- For WiFi, ensure that
-
Logs and Diagnostics: Check system logs using
dmesgor/var/log/messagesfor any errors or warnings related to WiFi and Bluetooth. These logs can provide valuable insights into what might be going wrong.
By following these steps, you should be able to identify and resolve the issues preventing Bluetooth and WiFi from functioning on your board. I hope this helps!
