Menggunakan script mkvendor.sh untuk membuat file

Siapkan developer environment

cd ~/android-cyanogenmod
make -j4 otatools

Hasilnya

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/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

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_[codename].mk, kernel (binary), recovery.fstab, dll

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