Integration RIL drivers to Imx8mp in Android 12

venkata_kiran — Wed, 11 Sep 2024 20:19:32 GMT

I am trying integration RIL drivers in imx9mp EVB.

Followed below steps:

1. Updated the file named "imx8mp_gki.fragment" located in "\android_build\vendor\nxp-opensource\kernel_imx\arch\arm64\configs" with following MACROs.

CONFIG_USB_SERIAL_WWAN=m
CONFIG_USB_SERIAL_OPTION=m
CONFIG_USB_WDM=m
CONFIG_USB_NET_QMI_WWAN=m
CONFIG_RMNET=m

2. Updated the file "SharedBoardConfig.mk" located in "\android_build\device\nxp\imx8m\evk_8mp" with following info.

ifeq ($(IMX8MP_USES_GKI),true)

BOARD_VENDOR_RAMDISK_KERNEL_MODULES += \

+$(KERNEL_OUT)/drivers/net/usb/qmi_wwan.ko \

+$(KERNEL_OUT)/drivers/usb/class/cdc-wdm.ko \

+$(KERNEL_OUT)/drivers/usb/serial/option.ko \

+$(KERNEL_OUT)/drivers/usb/serial/usb_wwan.ko \

+$(KERNEL_OUT)/drivers/net/ethernet/qualcomm/rmnet/rmnet.ko \

$(KERNEL_OUT)/mm/zsmalloc.ko \

$(KERNEL_OUT)/drivers/block/zram/zram.ko \

$(KERNEL_OUT)/drivers/soc/imx/soc-imx8m.ko \

Ran the build using following commands.

export MY_ANDROID=`pwd`
export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
export CLANG_PATH=/opt/prebuilt-android-clang
source build/envsetup.sh
lunch evk_8mp-userdebug
./imx-make.sh -j4 2>&1 | tee build-log.txt

Getting following error.

vendor/partner_gms

When i look for kernel object of qmi_wwan.ko is present at "android_build"

#find out/ -name qmi_wwan.

out/target/product/evk_8mp/obj/KERNEL_OBJ/drivers/net/usb/qmi_wwan.ko

But still i am seeing Build Falure.

Could you please suggest whether i am missing any steps here.?

You can try to define those .ko files in BOARD_VENDOR_KERNEL_MODULES
