Modified serial_adapter so log are allowed when using USB CDC ACM serial port emulation. Added dedicated thread for log processing of the highest application priority. This allows to transmit all logs without adding k_sleep anywhere else int the code. Introduced boot log thread is simpler than the default log threat which decreases flash footprint by a few dozen bytes. Added configuration for nrf52840_pca10056 which shows how to enable looging along with USB - among other, thread log processing is required. build command (form zephyr-project root directory) west build -d build/mcuboot/nrf52840_pca10056 -b nrf52840_pca10056 ./bootloader/mcuboot/boot/zephyr/ -- -DDTC_OVERLAY_FILE=./boards/nrf52840_pca10056_big.overlay -DOVERLAY_CONFIG=./usb_cdc_acm_log_recovery.conf Signed-off-by: Andrzej Puzdrowski <andrzej.puzdrowski@nordicsemi.no> |

mcuboot
This is mcuboot version 1.5.0
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.
Using MCUboot
Instructions for different operating systems can be found here:
Roadmap
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.
Browsing
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:
- boot/bootutil: The core of the bootloader itself.
- boot/boot_serial: Support for serial upgrade within the bootloader itself.
- boot/zephyr: Port of the bootloader to Zephyr
- boot/mynewt: Mynewt bootloader app
- imgtool: A tool to securely sign firmware images for booting by mcuboot.
- sim: A bootloader simulator for testing and regression
