아듀(Adieu) MbedOS~
2026년 7월 MbedOS 프로젝트 문을 닫습니다.
이미 ARM에서 손을 뗀후로 업데이트도 멈춰 있고,
새로운 MCU들도 추가되지 않는 상태 였습니다.
아래와 같은 대체 RTOS를 추천 했는데,
CMSIS RTX
FreeRTOS
Zephyr
이중 MbedOS와 성격이 가장 비슷한 RTOS는 Linux Foundation에서
관리하는 Zephyr RTOS입니다. 이미 Nordic Semiconductor의 경우
nRF Connect SDK로 공식 지원하고 있고 ST, NXP, Renesas를 포함한메이저 벤더들의 MCU 제품군, RP2040(라즈베리파이피코), ESP32와 같은 오픈소스 커뮤니티에서 많이 다루는 MCU들도 지원하고 있습니다.
MbedOS와 마찬가지로 Zephyr 환경에서 코드 호환성을 보장하고 있어서 지원하는 하드웨어들의 빠른 프로토타이핑을 가능하게 해줍니다.
코드주에서 2025년에 다루어 보려고 계획하고 있습니다.
아래 메시지 전문 입니다.

Important Update on Mbed - End of Life
Today we wanted to share some important updates with the Mbed community:
The Mbed platform and OS will reach end of life in July 2026, when the Mbed website will be archived and it will no longer be possible to build projects in our online tools
The device software - Mbed OS - is open source and will remain publicly available, but is no longer actively maintained by Arm
The Mbed TLS project is unaffected by this announcement and continues to be supported as part of the TrustedFirmware community project.
Mbed has been a hugely popular project since 2009, helping professional developers, educational users, and the maker community to create, secure, deploy and update thousands of applications on Arm-based hardware developed by Mbed partners and contributors. Embedded and IoT development has evolved and scaled significantly since it was introduced, and during this evolution, Arm has made significant investments in industry standards such as CMSIS, and in a suite of embedded and IoT development tools for both professional and academic use.
At the same time, projects supported by Arm like micro:bit, Arduino, and Raspberry Pi have gained momentum in educational settings and among the maker community, enabling many of the features that Mbed offered to become more widespread and accessible, from browser-based IDEs and hardware abstraction to code hosting and remote build services. We believe these needs are now best served by the wider ecosystem, without the need for direct support from Arm.
Arm remains committed to investing in IoT development, focusing on standards, tools, and educational content that we believe will serve industry and academia most effectively, as we continue to enable everyone to build the future of computing on Arm.
Recommendations for Mbed users
We recommend that educational institutions begin to investigate a move away from Mbed as a platform for teaching embedded development. The Arm Education team is actively working on creating alternative teaching and learning solutions in time for the new academic terms starting Fall/Autumn 2025. We welcome feedback from the academic community on this. Reach out to the team at: [email protected]
No new commercial projects should be started using Mbed, and any existing Mbed-based commercial projects should start to investigate alternative frameworks. For a list of frameworks please see the FAQs at the end of this document.
All users begin to migrate code and other data from Mbed.com to other platforms. An export tool is available in your Mbed account.
We will take a phased approach to support for the Mbed tooling and websites. Further updates will be shared in due course but for now all systems - Mbed.com, the Mbed forum, Keil Studio Cloud, and Mbed Studio - will continue to operate as normal.
Frequently Asked Questions
What happens to the Mbed website and forum?
The Mbed website and forum will operate as normal until further notice. We will provide ample notice of changes to these services.
What happens to the Mbed OS codebase?
Arm has already halted active maintenance and CI on the Mbed OS codebase. You should not expect to see any fixes or improvements before July 2026. After July 2026, the codebase will be archived in GitHub.
A community fork of Mbed OS, Mbed CE, is under active development. If you would like to continue contributing to Mbed we recommend starting here.
What happens to Mbed TLS?
The Mbed TLS project is not affected this change. Although it shares the Mbed name, Mbed TLS is now part of TrustedFirmware.org. Development of Mbed TLS continues as usual, with an active roadmap of feature releases (including LTS releases) and support as usual. For more details see: Mbed TLS
I use Mbed OS in a commercial product. What should I do?
The Mbed OS terms of use will not change, and you can continue to use Mbed OS in existing commercial or non-commercial projects.
I used Mbed.com to submit coursework and share code as part of my course. What should I do?
We recommend using GitHub or GitLab for repository hosting and sharing. If you currently use Mbed.com-hosted Mercurial repositories, you can export the content from your account.
How do I get a copy of my code?
You can download a complete backup of your code, ready to be uploaded to a code-hosting service like GitHub or GitLab, from your account.
Will I be able to build my Mbed project after the OS is deprecated?
You will not be able to build an Mbed project inside Keil Studio Cloud or Mbed Studio, but it may be possible to build a project with GCC using the Mbed CLI. As of today, Arm does not provide any support on the Mbed OS code base. This includes the Mbed CLI.
How do I delete my Mbed account?
You can delete your account from the account management page on mbed.com.
What can I use instead?
A community fork of Mbed OS – Mbed CE - is under active development. If you would like to continue contributing to or using Mbed we recommend starting here.
For a free-to-use embedded development environment we recommend Arm Keil MDK v6 Community Edition, which works seamlessly with the CMSIS standard and CMSIS RTX RTOS:
keil.arm.com
For rapid prototyping and educational purposes, we suggest you investigate:
Arduino (C/C++ based)
micro:bit (multiple programming abstractions)
Raspberry Pi Pico (multiple programming abstractions)
For an alternative RTOS we recommend:
CMSIS RTX
FreeRTOS
Zephyr
For embedded Linux projects we recommend:
Yocto
Raspberry Pi (computers)
