Teliti dmesg

Hasil dmesg juga akan menolong saat compile kernel. Lakukan

adb devices
adb shell
su

Karena hasilnya akan panjang sebaiknya di simpan di /sdcard

dmesg > /sdcard/dmesg.txt

Dari komputer dapat kita adb pull

adb pull /sdcard/dmesg.txt

Catatan ini di perlukan untuk mengidentifikasi module yang harus di compile

Teliti Modules yang perlu di perhatikan

Lakukan dari komputer / PC

adb devices
adb shell ls /sys/modul | more

Dari hasil yang keluar tampaknya file berikut ini penting, terutama saat mengcompile Custom ROM

ccci
ccci_plat
hid
hid_apple
hid_ntrig
mali
mtk_fm_drv
mtk_stp_bt_soc
mtk_stp_gps_soc
mtk_stp_wmt_soc
mtk_wmt_detect
mtk_wmt_wifi_soc
scsi_wait_scan
wlan_mt.ko

Jika ingin di simpan dapat menggunakan perintah

adb shell ls /sys/module > modules.txt

Dapatkan boot.img dan ramdisk.gz

adb devices
adb shell
su

dd if=/dev/block/mmcblk0boot0 of=/sdcard/boot0.img
dd if=/dev/block/mmcblk0boot1 of=/sdcard/boot1.img
exit

Di laptop / pc lakukan

adb pull /sdcard/boot0.img
adb pull /sdcard/boot1.img

Jika Beruntung Memperoleh upgrade ROM

cp evercoss_A80A.zip ~
cd ~
unzip evercoss_A80A.zip 
cd evercoss_A80A/
unrar x SW_W99601A4_V011_M10_EVERCOSS_KK\(A80A_1016\).rar
cd ~/evercoss_A80A/SW_W99601A4_V011_M10_EVERCOSS_KK/Software/

Kita membutuhkan

lk.bin
boot.img

Extrak dari boot.img upgrade ROM MTK

Download dari

https://github.com/bgcngm/mtk-tools/

Caranya

cd ~/Downloads
wget https://github.com/bgcngm/mtk-tools/archive/master.zip
mv master.zip MTK-tools.zip

Buka

unzip MTK-tools.zip

unpack boot.img dari upgrade ROM MTK

cd ~/lokasi-upgrade-ROM-MTK/
~/Downloads/mtk-tools-master/unpack-MTK.pl boot.img
gzip -cr boot.img-ramdisk > boot.img-ramdisk.gz  (tampaknya gz yang di hasilkan salah)

Ini akan menghasilkan

boot.img
boot.img-args.txt
boot.img-kernel
boot.img-kernel.img
boot.img-ramdisk/
boot.img-ramdisk.gz (tampaknya gz yang di hasilkan salah)

Dapatkan recovery.img

Dapatkan /proc/config.gz dan /proc/version

Tampaknya config.gz tidak tersedia di MTK

Menggunakan script mkvendor.sh untuk membuat file

Siapkan developer environment

cd ~/android-cyanogenmod
make -j4 otatools
export PATH=${PATH}:~/android-cyanogenmod/out/host/linux-x86/bin

Agar tidak ada error sebagai berikut

"unpackbootimg not found.
Is your android build environment set up and have the host tools been built?"

Buat secara automatis semua directory cyanogenmod yang dibutuhkan

cd ~/android-cyanogenmod
./build/tools/device/mkvendor.sh evercoss a80a ~/backup-A80A/KK-upgrade/boot.img

Dimana

vendor adalah evercoss
codename adalah a80a
boot.img berada di ~/backup-A80A/KK-upgrade/

Jika anda menggunakan recovery image

cd ~/android-cyanogenmod
./build/tools/device/mkvendor.sh evercoss a80a ~/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img

Dimana

vendor adalah evercoss
codename adalah a80a
recovery.img berada di ~/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img

entah kenapa boot.img-ramdisk.gz selalu dapat error dari gzip. Lakukan hack sedikit

mkdir -p /tmp/onno/bootimg/ramdisk/
cp -Rf /home/onno/backup-A80A/KK-upgrade/boot.img-ramdisk/* /tmp/onno/bootimg/ramdisk/
cp ./build/tools/device/mkvendor.sh ./build/tools/device/mkvendor.sh.asli
vi ./build/tools/device/mkvendor.sh

Ubah

mkdir ramdisk
pushd ramdisk > /dev/null
gunzip -c ../$BOOTIMAGEFILE-ramdisk.gz | cpio -i

Menjadi

mkdir ramdisk
pushd ramdisk > /dev/null
cp -Rf /home/onno/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img-ramdisk/* /tmp/onno/bootimg/ramdisk/

Buat secara automatis semua directory cyanogenmod yang dibutuhkan

cd ~/android-cyanogenmod
./build/tools/device/mkvendor.sh evercoss a80a ~/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img

Dimana

vendor adalah evercoss
codename adalah a80a
boot.img berada di ~/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img

Ulangi dengan

cp -Rf /home/onno/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img-ramdisk/* /tmp/onno/bootimg/ramdisk/
cd ~/android-cyanogenmod
./build/tools/device/mkvendor.sh evercoss a80a ~/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img
rm -Rf /home/onno/android-cyanogenmod/device/evercoss/
cd ~/android-cyanogenmod
./build/tools/device/mkvendor.sh evercoss a80a ~/backup-A80A/micromax-A350/TWRP_2810_Micromax_A350_KK.img

Done!
Use the following command to set up your build environment:
  lunch cm_a80a-eng
And use the follwowing command to build a recovery:
  . build/tools/device/makerecoveries.sh cm_a80a-eng

Perintah di atas akan membuat folder

/device/evercoss/a80a/

dalam struktur repo source CyanogenMod. Dalam folder tersebut ada file

AndroidBoard.mk
AndroidProducts.mk
BoardConfig.mk
cm.mk
device_a80a.mk
kernel
recovery.fstab
system.prop

Langkah di atas tidak akan membuat directory kernel/ . Kita perlu melakukannya nanti, saat kita sudah siap untuk membuat kernel.

Siapkan Kernel

Sumber source code kernel mediatek

cd ~
git clone https://android.googlesource.com/kernel/mediatek -b android-mediatek-sprout-3.4-kitkat-mr2

cd ~
mediatek

Siapkan folder di source android

cd ~/android-cyanogenmod/kernel/
cp -Rf ~/mediatek ~/android-cyanogenmod/kernel/

Ujicoba compile kernel

cd ~/android-cyanogenmod/kernel/mediatek/
make menuconfig
make all

Ada beberapa file .h yang tidak ada di folder

 cd ~/android-cyanogenmod/kernel/mediatek/include/mach

Yaitu,

mt_spm_idle.h
mt_devinfo.h
system.h
dfo_boot.h
env.h

Bisa di search di google menggunakan keyword

mediatek mach/nama_file.h

Copy pastekan ke folder

 cd ~/android-cyanogenmod/kernel/mediatek/include/mach

Error terakhir

kernel/power/tuxonice_prepare_image.c: In function 'toi_mark_task_as_pageset':
kernel/power/tuxonice_prepare_image.c:179:9: error: 'struct task_struct' has no member named 'on_cpu'

Nampaknya source code dari MTK tidak lengkap :(

Compile

cd ~/android-cyanogenmod/vendor/cm
./get-prebuilts

cd ~/android-cyanogenmod
source build/envsetup.sh
lunch cm_a80a-eng
lunch cm_a80a-userdebug

Tampaknya cm_a80a-eng tidak akan bisa karena a80a bukan OFFICIAL CM, maka keluar error

 Trying dependencies-only mode on a non-existing device tree?
