IMX8MP Android 11 Bluetooth AW-CM276NF

VeeraH · ‎07-21-2022

Hi,

We are trying to bring up bluetooth on IMX8MP board over UART1.

Added into Kernel command line:

BOARD_KERNEL_CMDLINE += androidboot.bt_uart=/dev/ttymxc0 androidboot.btmacaddr=2f:0b:a1:aa:bf:04

Added UART into device tree.

When we try to enable the bluetooth on Android UI, we are getting the following crash on logcat,

07-20 09:04:13.504 2066 2093 E bt_btif_config: Config is missing adapter section

Hi @VeeraH ,

1. Don't add any other buledroid stack to NXP Android BSP.

2. For andrdoid 11, Bluedroid stack is in system/bt

3. Even if NXP android 11 also supports SD8997 , default firmware is not suitable for you application.

~/android_11.0.0_2.6.0/vendor/nxp-opensource/nxp-mwifiex/mxm_wifiex/wlan_src/Makefile

# Multi-chipsets
CONFIG_SD8887=n
CONFIG_SD8897=n
CONFIG_USB8897=n
CONFIG_PCIE8897=n
CONFIG_SD8977=n
CONFIG_SD8978=y
CONFIG_USB8978=n
CONFIG_SD8997=y
CONFIG_USB8997=n
CONFIG_PCIE8997=y
CONFIG_SD8987=y
CONFIG_SD9097=n
CONFIG_SD9177=n
CONFIG_SD8801=y
CONFIG_USB8801=n
CONFIG_USB9097=n
CONFIG_PCIE9097=n
CONFIG_SD9098=n
CONFIG_USB9098=n
CONFIG_PCIE9098=y

BUT default firmware "~/android_11.0.0_2.6.0/vendor/nxp/imx-firmware/nxp/FwImage_8997/pcieuart8997_combo_v4.bin", only supports PCIe For wifi & UART For BT.

4. Would you please tell me your current driver version? (full version, please!)

5. Since you have NDA with NXP, create a new case in SFDC, let us discuss it in the system.

Hi,

We have some hardware issue with accessing bluetooth over serial port.

Please share your inputs whether it is possible to use SDSD access of wifi over SDIO and bluetooth over SDIO on android 11.

VeeraH · ‎07-26-2022

Bluetooth driver is up using SDIO interface as below,

evk_8mp:/ # hciconfig
hci0: Type: SDIO
BD Address: 00:E9:3A:9B:09:18 ACL MTU: 1021:7 SCO MTU: 120:6
UP RUNNING
RX bytes:1356 acl:0 sco:0 events:82 errors:0
TX bytes:1205 acl:0 sco:0 commands:82 errors:0

But when we try to enable / on bluetooth via android UI, it does not working.

please share your inputs.

Hello @VeeraH ,

If you want to use SDIO interface for Bluetooth. Driver will register it as a char device. Like below.

/dev/mbtchar0

it's usage is similar to that of UART.

Hi,

We are loading the following modules in sequence,

1. mlan.ko

2. bt8xxx.ko

3. moal.ko

We are getting following instance wlan0, wlan1, p2p0, hci0 only and no /dev/mbtchar0 got created.

Please share your inputs whether we have to load any other module to get /dev/mbtchar0 and please help to get the latest device driver.

Thanks,

Veera.H.

Hi @VeeraH ,

These 2 files is WIFI driver.

1. mlan.ko

2. moal.ko

This is Bluetooth driver

1. bt8xxx.ko

In default android 11 bsp, Bluetooth uses android default one. in kernel , it is bt_uart.ko , probably, you should remove it in linux kernel configuration.

you can try the following steps:

1. Loading bt8xxx.ko driver with bt firmware.

if it is successful, check if mbtchar0 is created in /dev/ path.

2. Loading wifi driver with wifi firmare

[Note]

(1)don't use combo firmware.

(2) you had better correct hareware issue of UART, and continue to use UART interface. because 8MP+android 11 supports 88W8997 PCIE UART by default.

[In additon]

If you have NDA and obtained NXP authorization, you can download the driver or other materials you need from our website.

Hi,

We have NDA with NXP, and we could not find the Bluetooth bluedroid based driver in NXP portal.

Please help us to get the latest driver from the portal.

We tried to use this bluedroid driver => https://github.com/hardkernel/buildroot_vendor_marvell_bt_sd8977/tree/aml64_buildroot_master/bluedro...

we ported for the 5.10.72 kernel and getting crash after the bluetooth firmware is downloaded.

Please share your inputs.

Thanks

Veera.H.
