boot: Change TLV tag to 16 bits The current TLV tag is an unsigned 8-bit integer, that is stored with 8 bits of padding. As the TLV tag is defined to be little endian (although the code doesn't properly handle this), we can use the 8 bits of padding as the upper 8-bits, treating the TLV tag as a 16 bit value, and all existing tags will operate as they did before. Change the types used throughout the code to represent the TLV to a `uint16_t`. Change the ANY tag type to `0xffff` instead of `0xff`. This value is never stored, but will avoid conflicts with any future allocated tags. Signed-off-by: David Brown <david.brown@linaro.org>
This is mcuboot version 1.4.0
MCUboot is a secure bootloader for 32-bit MCUs. The goal of MCUboot is to define a common infrastructure for the bootloader, system flash layout on microcontroller systems, and to provide a secure bootloader that enables simple software upgrades.
MCUboot is operating system and hardware independent and relies on hardware porting layers from the operating. Currently, mcuboot works with both the Apache Mynewt and Zephyr operating systems, but more ports are planned in the future. RIOT is currently supported as a boot target with a complete port planned.
Instructions for different operating systems can be found here:
The issues being planned and worked on are tracked using GitHub issues. To participate please visit:
Issues were previously tracked on MCUboot JIRA , but it is now deprecated.
Information and documentation on the bootloader are stored within the source.
It was previously also documented on confluence: MCUBoot Confluence however, it is now deprecated and not currently maintained
For more information in the source, here are some pointers:
Developers welcome!
