Root Filesystem

This module introduces the root filesystems provided in the Processor SDK Linux package.

The Processor SDK Linux package provides root filesystem (rootfs) images that contain programs, scripts, and Linux user-space components that abstract various hardware accelerators available in the SoC.

There are different filesystem images provided in the installed SDK under folder filesystem/ in the tarball format (*.tar.xz). They can be used to update the rootfs partition of a bootable SD Card, or setup the rootfs for NFS boot.

tisdk-edgeai-image

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

tisdk-tiny

This is a very small rootfs image, only a tens of megabytes, intended to be used as initramfs for the use cases such as flashing system image.

Besides these rootfs images provided in the SDK installer, the AM62Ax product folder on ti.com provides several WIC images. They are the raw bootable Linux images containing both bootloaders and rootfs. These images are independent to the SDK installer, and can be directly written to an SD Card to create a Linux bootable SD Card. Refer to Create a Linux Bootable SD Card for details of the SD Card writing process.
