UBootEnv

This library lets you read and write U-Boot environment blocks from Elixir. U-Boot environment blocks are simple key-value stores used by the U-Boot bootloader and applications that need to communicate with it. Nerves uses U-Boot environment blocks to store settings related to the device and running firmware. Nerves uses the format even for boards (like the Raspberry Pis) that don't use the U-Boot bootloader.

This library has the following features:

• Create, read, and write to U-Boot environment blocks in pure Elixir with OTP 21 and later
• Support for /etc/fw_env.config for environment block parameters

Not all U-Boot environment features are supported. The primary omissions are around support for raw NAND features like redundant environment blocks and awareness of erase block sizes. If you don't know what this means, it doesn't affect you.

Installation

Install by adding uboot_env to your list of dependencies in mix.exs:
