This is a Python implemented of blhost used to communicate with NXP MCUBOOT/KBOOT bootloader.

For now it only implements a subset of the blhost commands.

Current UART and CAN-Bus interfaces are supported.

Installation

pip install pyblhost

Usage

Python

See the examples directory for Python examples.

CLI
