Building coreboot

Preliminaries

Prior to building coreboot the following files are required:

  • Intel Flash Descriptor file (descriptor.bin)
  • Intel Management Engine firmware (me.bin)
  • ITE Embedded Controller firmware (ec.bin)

The files listed below are optional:

  • Splash screen image in Windows 3.1 BMP format (Logo.bmp)

These files exist in the correct location in the StarLabsLtd/blobs repo on GitHub which is used in place of the standard 3rdparty/blobs repo.

Build

The following commands will build a working image:

make distclean
make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_starbook_tgl
make

Flashing coreboot

Type Value
Socketed flash no
Vendor Winbond
Model 25Q128JVSQ
Size 16 MiB
Package SOIC-8
Internal flashing yes
External flashing yes

#### Requirements:

  • fwupd version 1.5.6 or later
  • The battery must be charged to at least 30%
  • The charger must be connected (either USB-C or DC Jack)
  • BIOS Lock must be disabled
  • Supported Linux distribution (Ubuntu 20.04 +, Linux Mint 20.1 + elementaryOS 6 +, Manjaro 21+)

fwupd 1.5.6 or later To check the version of fwupd you have installed, open a terminal window and enter the below command:

fwupdmgr –version


This will show the version number. **1.5.6** or greater will work.
![fwupd version](fwupdVersion.png)
On Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.1 and elementaryOS 6, fwupd 1.5.6 can be installed from our PPA with the below terminal commands:

sudo add-apt-repository ppa:starlabs/ppa sudo apt update sudo apt install fwupd


On Manjaro:

sudo pacman -Sy fwupd-git flashrom-starlabs


Instructions for other distributions will be added once fwupd 1.5.6 is available. If you are not using one of the distributions listed above, it is possible to install coreboot using a Live USB.

**Disable BIOS Lock**
BIOS Lock must be disabled when switching from the standard AMI (American Megatrends Inc.) firmware to coreboot. To disable BIOS Lock:

1\. Start with your LabTop turned off\. Turn it on whilst holding the **F2** key to access the BIOS settings.
2\. When the BIOS settings load, use the arrow keys to navigate to the **Advanced** tab\. Here you will see **BIOS Lock**\.
3\. Press `Enter` to change this setting from **Enabled** to **Disabled**

4\. Next, press the `F10` key to **Save & Exit** and then `Enter` to confirm.

#### **Switching Branch**

Switching branch refers to changing from AMI firmware to coreboot, or vice versa.

First, check for new firmware files with the below terminal command:

fwupdmgr refresh –force


Then, to change branch, enter the below terminal command:

fwupdmgr switch-branch


You can then select which branch you would like to use, by typing in the corresponding number:
![Switch Branch](SwitchBranch.png)
You will be prompted to confirm, press `y` to continue or `n` to cancel.

Once the switch has been completed, you will be prompted to restart.

The next reboot can take up to **5 minutes,** do not interrupt this process or disconnect the charger. Once the reboot is complete, that's it - you'll continue to receive updates for whichever branch you are using.

You can switch branch at any time.
