This repository contains miscellaneous boot-related tools for i.MX8 platforms.

Derived from tegra-boot-tools.

The imx-bootinfo tool provides storage, similar to U-Boot environment variables, for information that should persist across reboots. The variables are stored (with redundancy) outside of any Linux filesystem.

The keystoretool tool leverages secure key and encrypted key support in the Linux kernel on i.MX SoCs to create a key for use with dm-crypt to encrypt filesystem partitions, persistently storing the blobbed/wrapped keys using imx-bootinfo's variable storage. The CLI is derived from a similar tool for use with the keystore TA on NVIDIA Jetson platforms, but the underlying implementation leverages CAAM features of the i.MX.

The imx-otp-tool tool provides access to the eFuses exported through the imx-ocotp driver's nvmem interface, mainly for automating secure boot setup. PLEASE NOTE that incorrect manipulation of the eFuses can render your device unbootable. USE AT YOUR OWN RISK.

This package uses CMake for building.

This package depends on systemd, libz, and libkeyutils.
