This repository provides access to various tools for using the Rigado Secure Bootloader.
The Rigado Secure Bootloader provides an encryption scheme allowing module users to secure their firmware image during over-the-air and serial-wire transfer. This method works by first installing a private 128-bit key on each device. The update images are then encrypted using the key for the device. After transfer of the encrypyted image, the image is decrypted on the device side and validated using a checksum. If all checks pass, the new firmware image is flashed to the application bank on the device.

RigDFU v3.2.1 as programmed at the factory has an issue that keeps it from being properly updated. This only affects BLE or serial based updates of the Bootloader and/or Bootlaoder+SoftDevice. To update v3.2.1 to another version of the bootloader, use the update binary found in the rigdfu_errata folder. This folder contains an application that reconditions the factory image and updates the bootloader to v3.2.3. This process must be followed to update any module with v3.2.1 to another version of the bootloader (such as 3.3.1 using SoftDevice S132 3.x.0). If this update is not applied first, then device will require a JLink to recover.
