3.3. Filesystem

Introduction

The Processor SDK Linux provides Filesystem Images that contain programs, scripts, Linux user-space components that abstract various hardware accelerators available in the SoC. The Filesystem can be fully assembled via Yocto, following the instructions Processor_SDK_Building_The_SDK.

Filesystem Images

There are different filesystem images provided in the SDK. You’ll find them at the SDK Installation directory/filesystem folder.

arago-base-tisdk-image

This is the barebones images, intended to be a starting point for users to add packages and create a custom filesystem that suits their project needs.

tisdk-rootfs-image

This is the complete filesystem image, that contains standard Linux commands and features. This also contains the TI component libraries, binaries and out of box examples.

For keystone devices (e.g., K2H/K2K, K2E, K2L, and K2G), two filesystem tarballs are provided due to size limit of the rootfs ubi image:

• tisdk-server-rootfs-image-k2g-evm.tar.gz: base filesystem image used to create the ubi image.
• tisdk-server-extra-rootfs-image-k2g-evm.tar.gz: complete filesystem image that can be used with NFS and/or SD card (K2G only).

tisdk-docker-rootfs-image

This is a minimal image with support for Docker. See Docker Linux Container Runtime for more information.

arago-tiny-image

This is the absolute minimal filesystem. The boot files are omitted from this image and systemd has been replaced with sysvinit.
