sim: Use non-equal security counters when testing upgrades

When testing upgrades, the simulator was always using two images having
the same security counter. This was preventing to test that the security
counters are updated at the right time in the scenarios where a revert
is possible. The upgrade image is now generated with a higher security
counter than the original image, enabling to detect e.g. the issue fixed
by the previous commit.

MCUboot

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

This is MCUboot version 2.2.0-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.
