Precautions
- 1. At least 5.10 kernel is required for normal use in Linux environment
- 2. The latest Raspberry Pi system can directly identify the device, only need to add the firmware, and the old system needs to recompile the kernel
- 3. Connection: The connection method of WIFI is PCIe, and the connection method of Bluetooth is USB
Usage Instructions
Just add the firmware to the latest Raspberry Pi system
Update Firmware and Kernel
sudo apt update sudo rpi-update
WIFI
Due to the large number of Wi-Fi options supported by the "intel wireless wifi MVM" driver, it is not limited to AX210 or AX200
If the kernel is compiled with "intel wireless wifi MVM" enabled
Then check the log to see if it shows:
dmesg | grep iwlwifi [ 4.574560] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002) ..................... [ 4.586465] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-59.ucode failed with error -2 [ 4.586562] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-59.ucode failed with error -2 .....................
Among them, iwlwifi-ty-a0-gf-a0-59.ucode indicates the missing driver file, you can click here to download the firmware
You can click here to download more firmwares
Copy the firmware to the /lib/firmware/ directory
If the firmware is loaded successfully, it means that the firmware is included by default and can be used directly
Bluetooth
Check the logs
dmesg | grep hci ..................... [ 6.301299] bluetooth hci0: loading /lib/firmware/intel/ibt-12-16.sfi failed with error -20 [ 6.301321] bluetooth hci0: Direct firmware load for intel/ibt-12-16.sfi failed with error -20 .....................
The above content indicates that the corresponding file is missing (for example, the log above shows the lack of the "ibt-12-16.sfi" driver file in "/lib/firmware/intel"). You can download the latest driver from the internet, or use the driver file we provide. In the firmware/intel directory, simply copy /lib/firmware/intel
Execute hciconfig
pi@raspberrypi:~ $ hciconfig hci0: Type: Primary Bus: USB BD Address: D8:3B:BF:46:2B:1A ACL MTU: 1021:4 SCO MTU: 96:6 UP RUNNING RX bytes:813 acl:0 sco:0 events:62 errors:0 TX bytes:3683 acl:0 sco:0 commands:62 errors:0
The UP RUNNING state indicates normal operation, while DOWN signifies it is not working properly, possibly due to being closed or lacking driver files
If it is DOWN, you can try to execute it, and if there is insufficient permissions, add sudo
hciconfig hci0 up More commands Turn off Bluetooth: hciconfig hci0 down Reset Bluetooth: hciconfig hci0 reset Scan Bluetooth devices: hcitool scan
Among these, hci0 is the Bluetooth device ID. If your CM4 comes with a WiFi Bluetooth module, then pay attention to observe whether Bus: is followed by USB or UART. The Bluetooth device of AX200 is a USB Bluetooth

If it can recognize all network cards and Bluetooth devices but cannot connect, remember to check if the antenna is connected

Debugging Precautions
1. In a Linux environment, first check the hardware connections. "lspci" can be used to see if the devices are correctly connected
2. Check the log "dmesg| grep iwlwifi" in a Linux environment to confirm what driver files are missing
3. If there is no output when running "dmesg | grep iwlwifi" in a Linux environment, you can try restarting or checking the Linux kernel version to ensure it is greater than or equal to 5.11
4. In a Linux environment, you can check the status of Bluetooth startup and verify if the driver file is missing by using the command "dmesg | grep bluetooth”
5. The Linux environment ensures that the Bluetooth device is working properly via "HCICONFIG"
