boot_serial: support fragmentation for outgoing SMP packets

The mcumgr packet sent over serial should be fragmented into frames of
up to 127 bytes, including 2-bytes frame start header and 1-byte for
terminating newline [1], resulting in up to 124 bytes for the base64
encoded payload.

Current implementation doesn't fulfill above requirement and transmits
single frames, without considering their length. This change introduces
support for fragmenting as defined in 'SMP over console' specification.

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 1.10.0-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.
