Build Instructions (Linux & OS X)

The instructions below will help you build Silk for the supported devices on Linux and OS X.

Prerequisites

• For Linux users: see Prerequisites (Linux)
• For OS X users: see Prerequisites (OS X)

We also provide a Docker image.

Building and using the emulator

git clone https://github.com/silklabs/silk.git
cd silk/bsp-gonk/
./sync qemu
source build/envsetup.sh
make -j4
./run-emulator

In a new terminal:

adb wait-for-device
adb logcat

Building for Nexus 4 (mako)

Cloning

Cloning should be always the same:

git clone https://github.com/silklabs/silk.git
cd silk/bsp-gonk/

Unlocking the bootloader

then, building and flashing for mako is going to need your device's bootloader to be unlocked, if it is you can skip this part. But if you don't know what's unlocking a bootloader, chances are you need to follow these steps as well.

1- Power off your LG / Google Nexus 4 device. Boot it into Fastboot mode by pressing at the same time the Volume down and Power buttons. When the screen shows the “start” text, release the buttons.

2- Connect your device to your computer via USB.

3- Run fastboot oem unlock from your terminal.

That should unlock your Nexus 4 device.

Building from source

Now for the actual building process:

./sync mako
source build/envsetup.sh
make -j4

Flashing to devices

You're going to want to to switch again to Fastboot, but if it's still on it from the unlocking process then you can skip this. Otherwise run:

adb reboot-bootloader

and then make sure fastboot can recognize your device correctly by running

fastboot devices

Your output should be similar to this 0079aa645d500341 fastboot
Where 0079aa645d500341 will be different for different devices.

fastboot flash all

Which will flash the Silk device img files onto it. And lastly reboot to Silk by running:

fastboot reboot

After the devices has successfully rebooted. Try running these commands to ensure that it's up and running.

adb wait-for-device
adb logcat

Re-flashing

Flashing another img requires to boot into bootloader again whether by following step 1 in Unlocking the bootloader section or running

adb reboot-bootloader

and then another

fastboot flash all

Flashing a stock Android rom again

If you want to switch back to normal Android, here are the instructions for flashing Android 5.1.1 to your device:

First download the stock Nexus 4 5.1.1 (LMY47V) ROM from https://dl.google.com/dl/android/aosp/occam-lmy47v-factory-b0c4eb3d.tgz then

occam-lmy47v-factory-b0c4eb3d.tgz
cd occam-lmy47v
./flash.sh
