How to export new symbols on IMX8MP android-14.0.0_2.2.0

[liangyan]

Hi NXP

how to export new kernel symbols on android-14.0.0_2.2.0. I refer to this https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Export-new-symbols-of-GKI-development-An.... 

But it does not work on android-14.0.0_2.2.0 BSP.

Please help me, How should I do ?

Sure! I can help you with that. Could you let me know which part you're having trouble with specifically? For setting up steps on the IMX8MP platform, it usually involves preparing the environment, loading necessary tools, and following the build or configuration process. I can guide you through step-by-step once I know where you're stuck. Let me know!

mkdir gki && cd gki (Make sure folder gki is not inside of ${MY_ANDROID})
epo init -u https://android.googlesource.com/kernel/manifest -b commonandroid15-6.6
repo sync
cd common

git remote add device <device kernel git URL> (I do not know how to do it)
git remote update (I do not know how to do it)
git checkout device/<device kernel branch> (I do not know how to do it)
git apply <all device patches if needed> (I do not know how to do it)
cd ..
ln -s ${MY_ANDROID}/vendor/nxp-opensource/verisilicon_sw_isp_vvcam
verisilicon_sw_isp_vvcam
ln -s ${MY_ANDROID}/vendor/nxp-opensource/nxp-mwifiex nxp-mwifiex

Hi @liangyan 

Please refer to the update android user guide.

Android User's Guide

The <device kernel git URL> is url of linux-imx.

you can try below commands:

git remote add device http://github.com/nxp-imx/linux-imx
git remote update

I show my steps:

step1: export MY_ANDROID=../IMX8MP_Android14/(aosp source code dir)

step2: mkdir gki && cd gki

step3: repo init -u https://android.googlesource.com/kernel/manifest -b common-android15-6.6

step4：repo sync

step5: cd common

step6: git remote add device <device kernel git URL>  (I do not know how to do)

step7:git remote update ((I do not know how to do))

step8: git checkout device/<device kernel branch> (I do not know how to do)

step9:git apply <all device patches if needed>(I do not know how to do)

step10:cd ..

step11: ln -s ${MY_ANDROID}/vendor/nxp-opensource/verisilicon_sw_isp_vvcam
verisilicon_sw_isp_vvcam

steop12:ln -s ${MY_ANDROID}/vendor/nxp-opensource/nxp-mwifiex nxp-mwifiex

step13: BUILD_FOR_GKI=yes BUILD_CONFIG=common/build.config.imx

step14:EXT_MODULES_MAKEFILE="verisilicon_sw_isp_vvcam/vvcam/v4l2/Kbuild"

step15:EXT_MODULES="nxp-mwifiex/mxm_wifiex/wlan_src"

step16:
