imgtool: change --max-align default value

The value of `--max-align` parameter passed to imgtool can never be
less than the value of `--align` parameter. At present the default
value of `--max-align` is fixed at 8. This forces user to pass the
parameter even when its value can be safely inferred.

Change the default value of the `--max-align` parameter to the larger
of the two values: `--align` or 8. Consequently, the user is required
to pass the parameter only if the flash alignment of the primary and
secondary slot differ.

MCUboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is MCUboot version 1.9.0-rc1

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a common infrastructure for the bootloader and the system flash layout on microcontroller systems, and provides a secure bootloader that enables easy software upgrade.

MCUboot is not dependent on any specific operating system and hardware and relies on hardware porting layers from the operating system it works with. Currently, MCUboot works with the following operating systems and SoCs:

RIOT is supported only as a boot target. We will accept any new port contributed by the community once it is good enough.

MCUboot How-tos

See the following pages for instructions on using MCUboot with different operating systems and SoCs:

There are also instructions for the Simulator.

Roadmap

The issues being planned and worked on are tracked using GitHub issues. To give your input, visit MCUboot GitHub Issues.
