Tibbo’s Ubuntu-based distribution for the LTPP3(G2) offers a solid starting point for your development needs. However, you’ll likely want to customize your image with additional components as required by your projects.
Tibbo offers a Docker container with build tools to help you easily customize images for the LTPP3(G2). By default, the system console is not displayed on the HDMI output. This is done for security reasons. This article is designed to help you build your own version of Ubuntu with this feature enabled.
Software Requirements:
- Docker Desktop
- An SSH terminal client (e.g., IO Ninja)
- (Optional) A serial terminal client (e.g., IO Ninja)
Building a Customized Image:
- Pull and run Tibbo’s Docker container, then connect to it via SSH. See this article for a detailed guide on how to perform these steps.
- Navigate to the folder SP7021 and run make kconfig. This opens the Kernel Configuration Menu.
