Bluetooth and WiFi on iMx8mqevk Android 12.1.0_1.0.0 not working

[rmani0029]

I downloaded the android source 12.1.0_1.0.0, compiled it on my Linux computer, and then flashed the resulting images to the SD card.

SD card that has been flashed is used to start the imx8mqevk device. The default UI and applications of the Android image are loaded correctly. However, the Bluetooth and WiFi don't work when I attempt to activate them. The following Bluetooth and Wifi configuration was added to the kernel, but it still won't switch on.

 CONFIG_SERIAL_IMX
 CONFIG_TTY
 CONFIG_BT_HCIUART
 CONFIG_BT_HCIUART_H4
 CONFIG_BT
 CONFIG_BT_RFCOMM
 CONFIG_BT_RFCOMM_TTY
 CONFIG_BT_BNEP
 CONFIG_BT_BNEP_MC_FILTER
 CONFIG_BT_BNEP_PROTO_FILTER
 CONFIG_BT_HIDP

 CONFIG_MAC80211

Hello @rmani0029 

I hope you are doing well.

->Please check with the pre-built image, it has in-built wifi & Bluetooth driver.
https://www.nxp.com/design/software/embedded-software/i-mx-software/android-os-for-i-mx-applications...

->By default, they are set to m but one can load them manually and if not then one can load them into init.rc which will load these drivers on every boot.

Thanks & Regards.

Hi @Sanket_Parekh ,

I downloaded and flashed the android-13.0.0_1.0.0_image_8mqevk demo image on the imx8mq board, but the wifi and bluetooth did not function.

I attempted using the compiled source but encountered same problems. Although the .ko files can be manually loaded, the insmod is unable to load it; it appears that some dependent files are missing. If the wifi and bluetooth modules' kernel configurations are set to "m" by default, could you please tell me how to change them to "y"?

I tried changing them to "y," but the changes weren't reflected in the output image.

Could you give guidance on how to install the necessary device driver for enabling bluetooth and wifi on android image.

Hello @rmani0029 ,

I hope you are doing well.

If the wifi and Bluetooth modules' kernel configurations are set to "m" by default, could you please tell me how to change them to "y"?
Please check it at android_build/vendor/nxp-opensource/kernel_imx/arch/arm64/configs/*defconfig file.

for Bluetooth:-

CONFIG_BT=y
CONFIG_BT_RFCOMM=y
CONFIG_BT_RFCOMM_TTY=y
CONFIG_BT_BNEP=y
CONFIG_BT_BNEP_MC_FILTER=y
CONFIG_BT_BNEP_PROTO_FILTER=y
CONFIG_BT_HIDP=y
CONFIG_BT_LEDS=y
CONFIG_BT_HCIBTUSB=m
CONFIG_BT_HCIUART=y
CONFIG_BT_HCIUART_BCSP=y
CONFIG_BT_HCIUART_ATH3K=y
CONFIG_BT_HCIUART_LL=y
CONFIG_BT_HCIUART_3WIRE=y
CONFIG_BT_HCIUART_BCM=y
CONFIG_BT_HCIUART_QCA=y
CONFIG_BT_HCIVHCI=y

for wifi:-

CONFIG_CFG80211=y
CONFIG_CFG80211_WEXT=y
CONFIG_MAC80211=y

Please make sure if one is using another vendor's wifi chipset and not nxp then make sure to set it y
for example:- CONFIG_WLAN_VENDOR_BROADCOM=y

Please check the rest kernel configurations options are set in a proper manner.

Further More

Please check with the Drivers that are loaded then also make sure that firmware is available at the spot or not.
Basically, Drivers can be loaded but the chipset also requests for firmware at a specific location. So please make sure that the firmware is there.

and about the required device driver, so all the device drivers are already taken care of in the pre-built image.
Just one can cross-compile those wifi or bt driver and put those .ko files into the /lib/modules section and the same with the bt also. then one can add this insmod or modprobe command into init.rc file so that they are loaded on every boot up.

from the logs, it is seen that the configurations for Bluetooth are already correct and its service also starts but still check if the module which is being used is well-connected or not.

one can check the dmesg logs the same if the chipset is detected correctly or not and then the firmware and drivers are installed or not.

Thanks & Regards

Hi @Sanket_Parekh ,

According to your previous post, I included all kernel configurations for WiFi and Bluetooth.

It throws the following issues related the cfg80211 module while booting the compiled android image.

Error Logs :

Can you give some guidance on how to solve this issues.

[Sanket_Parekh]

Hello @rmani0029 ,

I hope you are doing well.

->It is seen from the logs that there is a version mismatch problem occurs for cfg80211.
->Clearly it is trying to load them from the location but it is not there.

->Please try to cross-compile the cfg80211 drivers for the arm64 Linux kernel you are using and put them at the location they are getting requested to load from.
->Please make sure in the .config file when one builds the kernel there is config_cfg80211=y set.
->It will help.

Thanks & Regards,

Hi @Sanket_Parekh ,

IMx8 MQEVK prebuilt images also WiFi and Bluetooth are not working , I tried android 10, 11, 12 and 13 also. What is the exact root cause for this issues?

[rmani0029]

Hi,

I included required bluetooth and wifi kernel configurations and built the android image, final .config file also included the wifi and bluetooth related configurations.

For Bluetooth required kernel modules are initialized see the following logs for your reference,

But bluetooth qca module not loaded in the android image, I checked using the lsmod command.

I don't know where is the exact issues, could you help me how to enable the bluetooth and wifi on imx8mqevk android image.

Regards,

Hello @rmani0029 ,

I hope you are doing well.

->According to the android version one is using, Please cross-compile the wifi driver based on the Linux kernel version.
->Then copy that mlan.ko & moal.ko (cross-compiled driver) to the /vendor/lib/modules as shown in the commands.

--> adb push <from> <where>
--> adb pull <from> <where>

Kindly follow the above commands to copy those drivers.
->insert the mlan and PCIe modules as per the below command
-->insmod /vendor/lib/modules/mlan.ko && insmod /vendor/lib/modules/pcie8xxx.ko fw_name=pcieuart8997_combo_v4.bin host_mlme=1 cal_data_cfg=none cfg80211_wext=0xf drvdbg=0x20037
->lsmod | grep mlan
->dmesg | grep <chipset> (for example if chipset is 88w9098 then 9098).
->ifconfig wlan0 up
->Ifconfig -a
->iw dev wlan0 scan

->If one wants to get rid of this every time load, unload then simply put this insmod command into init.rc file.
->It will help!

Thanks & Regards,

Sanket Parekh

Hi @Sanket_Parekh ,

Thanks for your reply.

I could see the mlan driver loaded on lsmod.

evk_8mq:/ # lsmod | grep mlan
mlan 933888 0

However, the moal driver was not loaded due to cfg80211 dependencies.Please see the below dmesg logs.

For enabling Bluetooth and WiFi on the Android side, I am totally blocked from doing so. Would you kindly assist me in setting up the wifi and bluetooth?
