Prepare Target to Install ECI Deb Packages¶
The section is applicable to:
To leverage all ECI features, the target system should meet the recommended system requirements. Also, the target system must have a compatible OS so that you can install ECI Deb packages.
This section explains the procedure to install a compatible OS on the target system.
Do the following to prepare the target system:
Install the AMD64 variant of either Debian 11 (Bullseye), Ubuntu 22.04 (Jammy Jellyfish), or the ECI installation images on to the target system. Refer to the following table for details:
Distribution
Description
Where to Download
Instructions
Debian
Open-source Debian 11 (Bullseye)
ECI installation image for
core-bullseye◆N/A
Ubuntu
Open-source Ubuntu 22.04 (Jammy Jellyfish)
ECI installation image for
core-jammy◆N/A
Note: ◆ These ECI installation images enable you to quickly get started with a blank canvas ready for customization. They are minimal builds of Debian or Ubuntu with the ECI Linux Intel LTS PREEMPT_RT kernel already installed and boot parameters already configured.
To achieve real-time determinism and utilize the available Intel® silicon features, you need to configure certain BIOS settings. Reboot the target system and access the BIOS (press the delete or F2 keys while booting to open the BIOS menu).
Select Restore Defaults or Load Defaults, and then select Save Changes and Reset. As the target system boots, access the BIOS again.
Modify the BIOS configuration as listed in the following table.
Note: The available configurations depend on the platform, BIOS in use, or both. Modify as many configurations as possible.
