MCUboot and ota examples changelog

MCUboot and ota examples changelog#

All notable changes to MCUboot fork in MCUXpresso SDK and related ota examples will be documented in this file.

[26.06.0] - 06/2026#

Changed#

  • Optimized PSA configuration for mcuboot_opensource to reduce binary size

  • Switch default TinyCrypt to PSA crypto backend to speed up boot process on boards FRDM-MCXA266 and FRDM-MCXA366

  • Changed flash partition layout on boards FRDM-MCXA266 and FRDM-MCXA366

  • (Encrypted XIP) Moved IPED dependencies in MCUBoot loader code to flash backend, documentation updated

  • (Encrypted XIP) Documentation updated

[26.03.0] - 03/2026#

Added#

  • MCUboot updated to v2.3.0

  • Enabled ota_rom_basic for FRDM-MCXN236

  • Added new upgrade mode SINGLE_APPLICATION_SLOT

  • Enabled serial recovery feature (see Serial Recovery doc)

Changed#

  • Update Mbed TLS to 3.0 in ota_mcuboot_client example

  • Specify terminology of upgrade modes supported in ota examples with MCUBoot (see README)

  • FRDM-MCXA153 configured to use SINGLE_APPLICATION_SLOT mode due to its very limited flash size

  • LPCXpresso55S69 configured to use TinyCrypt due to higher flash usage of the latest mcuboot+mbedtls. Original prj.conf is left for reference.

[25.12.0] - 12/2025#

Added#

  • Added basic support for KW47-EVK and MCX-W72-EVK board

  • Added SB3 processing support for MIMXRT700EVK (see SB3 doc)

[25.09.0] - 09/2025#

Fixed#

  • (Encrypted XIP)(IPED) Fixed issue between IPED and PKC

Added#

Changed#

  • Update MCUboot to 2.2.0

  • Update Mbed TLS to 3.0 in mcuboot_opensource example

    • PSA Crypto API (MCUBOOT_USE_PSA_CRYPTO) is used in default configurations to utilize hardware acceleration

    • Legacy API (MCUBOOT_USE_MBED_TLS) is used in configuration using Encrypted XIP due limitations in PSA Crypto API in current MCUboot version

    • EC256 made as default signature algorithm replacing obsolete RSA

      • it is still possible to manually setup RSA but only for legacy API

  • Encrypted XIP: reworked the layer to use only the overwrite mode

  • Changed default partition layout on FRDM-RW612, RD-RW612BGA and EVKCMIMXRT1060:

    • mcuboot_opensource: 256kB

    • application: 2MB

Removed#

  • Encrypted XIP: removed the experimental three-slot mode

[25.06.0] - 06/2025#

Added#

  • Added ota_rom_basic example demonstrating ROM bootloader processing a secure binary as an OTA image (see documentation in docs folder)

  • Enabled ota_rom_basic example for FRDM-MCXN947, MCX-N9XX-EVK, FRDM-RW612 and RD-RW612BGA

  • Enabled flash remap feature for MIMXRT700EVK

  • FRDM-MCXE247 basic MCUboot support

  • FRDM-MCXN947, MCX-N5XX-EVK and MCX-N9XX-EVK supports alternative build using MCUboot located in the internal flash instead of the IFR region (default) - see board specific readme for more information

Removed#

  • Removed ota_rom_server (replaced by simpler ota_rom_basic)

[25.03.0] - 03/2025#

Added#

  • (MCXA20) Basic support for FRDM-MCXA276 and FRDM-MCXA166

  • Added SB3 processing support in ota_mcuboot_basic example for selected platforms

  • (MCXN)(RW61x) Enabled SB3 processing support for FRDM-MCXN947, MCXN9XXEVK, FRDM-RW612 and RD-RW612BGA

Changed#

  • Update MCUboot to 2.1.0

Fixed#

  • (Encrypted XIP)(IPED) Fixed issues in wifi based examples using IPED encryption

  • (Encrypted XIP) Fixed missing default encryption keys

Removed#

  • Removed support for MDK toolchain

[24.12.0] - 12/2024#

Added#

  • Initial release

Removed#

  • Removed WiFi OTA examples on boards that also support Ethernet
