User manual
This section shows how to enable the uSD/M.2 88W8987-based wireless module in the
Android 10 image, and the set of modifications to implement prior to initiating the Android
10 image build process.
The following configuration modifications are required before starting the Android 10
image build process.
Step 1: Open and modify the BoardConfig.mk file to enable the device tree support for
M.2. The file path is <absolute-path>/android_build/device/fsl/imx8m/
evk_8mq/.
Replace the following line
TARGET_BOARD_DTS_CONFIG ?= imx8mq:imx8mq-evk-pcie1-m2.dtb
with
TARGET_BOARD_DTS_CONFIG ?= imx8mq:imx8mq-evk-usdhc2-m2.dtb
Step 2: Open and modify the SharedBoardConfig.mk file to add NXP 88W8987 Wi-Fi
driver module support. The file path is <absolute-path>/android_build/device/
fsl/imx8m/evk_8mq/.
Replace the following lines
#NXP 8997 wifi driver module
BOARD_VENDOR_KERNEL_MODULES += \
$(KERNEL_OUT)/drivers/net/wireless/marvell/mrvl8997/wlan_src/mlan.ko
\
$(KERNEL_OUT)/drivers/net/wireless/marvell/mrvl8997/wlan_src/
pcie8xxx.ko
with
# NXP 8987 wifi driver module
BOARD_VENDOR_KERNEL_MODULES += \
$(KERNEL_OUT)/drivers/net/wireless/nxp/mxm_wifiex/wlan_src/mlan.ko \
$(KERNEL_OUT)/drivers/net/wireless/nxp/mxm_wifiex/wlan_src/moal.ko
Step 3: Open and modify the UbootKernelBoardConfig.mk file to enable additional
default configuration. The path is <absolute-path>/android_build/device/fsl/
imx8m/evk_8mq/.
Replace the following line
# TARGET_KERNEL_ADDITION_DEFCONF ?= android_addition_defconfig
with
TARGET_KERNEL_ADDITION_DEFCONF ?= android_addition_defconfig
