This is the release note for mbed OS 5.3.0, summarizing the major enhancements in this version.

You can find the mbed OS 5.3.0 release on GitHub.

About this release

This release makes available early versions of key new features we are working on in development branches, alongside many enhancements and bug fixes to our stable release codeline. These new features will be of particular interest to partners and developers who would like to observe and contribute to their development ahead of them being made generally available.

The new feature developments made available are:

• Initial CMSIS5 and CMSIS-RTOS2 upgrade
• Integration points for Hardware Acceleration of Symmetric and Asymmetric Encryption
• Introduction of native LoRaWAN APIs

You can follow our development of these features - and contribute to them - by working with the feature branches linked above.

In addition, the main mbed OS 5.3 release includes a number of fixes since 5.2 and now supports 70 target platforms.

The following sections provide more details of these and other changes in this release.

Core

A first functional integration of the next generation CMSIS5 libraries, including the new CMSIS-RTOS2 RTOS kernel. This upgrade is integrated under the mbed OS Peripheral and RTOS APIs such that it will have little or no impact on developers, but provides important enhancements that can be taken advantage of internally.

These enhancements include:

• Primitives and integration points for supporting TrustZone for Cortex-M and mbed uVisor
• Improved RTOS kernel
• Support for ARM Compiler 6
• Many patches and modifications that mbed OS had made to CMSIS4 and CMSIS-RTOS now incorporated directly in to the CMSIS5 and CMSIS-RTOS2 codebases

This allows tracking of the latest CMSIS5 development, and will be brought in to the mainline release when it is ready. Impact on end developers when this happens should be very limited, but open up further opportunities for mbed OS functionality and portability.

Security

Building on the Hardware Entropy work in mbed OS 5.2, mbed OS 5.3 adds the integration points for implementing Hardware Acceleration on different target platforms. This support extends to both Symmetric and Asymmetric encryption operations, and when implemented for a target will transparently provide benefit for developers directly or indirectly using functions that rely on TLS/DTLS or other Cryptographic operations.

Partners looking to provide implementations for their targets should contact their ARM Partner Enablement representative for guidance, such that support can be made available for developers using their platforms in future mbed OS releases.

Connectivity

New LoRaWAN APIs are introduced to provide native development support for LoRaWAN applications on any mbed Enabled LoRa hardware. These APIs are available for partners and developers to analyze and help refine whilst the full mbed OS LoRaWAN stack is integrated, ahead of making it available as part of our mainline release. In particular, please contact us if you have an interest in LoRa and LoraWAN as a module manufacturer, OEM product developer or network provider.

Wi-Fi support has also been further improved, with built in support for both the u-blox ODIN-W2 and Espressif ESP8266 modules. Look out for further partner support, which will become available in patch releases.

Targets

Thanks to our partners’ hard work, mbed OS 5.3 supports 70 targets platforms.

We will continue to add new targets in our bi-weekly releases as partners introduce support.

Fixes and Changes

Please see the mbed-os GitHub repository referenced below for a full list of changes introduced in this release.

Known Issues

[Beetle] BLE scan doesn't work on BLE.

• Description: On the beetle board, BLE scanning doesn't work and the scan procedure will never report any advertisement even if the procedure has been successfully launched.
• Workaround: None
• Reported Issue: #3400

Odin Ethernet requires configuration

• Description: The default network interface for the Odin is Wi-Fi.
• Workaround: Make Ethernet the default interface by removing “EMAC” from “device_has” in targets.json
• Reported Issue: #3419

sockets do not work for NUCLEO_F746ZG using IAR toolchain

• Description: The mbed-os-example-sockets program doesn't work when building with IAR
• Workaround: None
• Reported Issue: #3387

NUMAKER_ PFM_NUC472 does not work with uvision

• Description: Error says IPv4 or IPv6 must be enabled
• Workaround: None
• Reported Issue: #3418

mbed TLS causes stack overflow in mbed OS targets

• Description:
  The stack memory usage of some mbed TLS features is higher than 4 KB, which may cause stack overflow errors when running in constrained embedded environments with mbed OS which are particularly limited in RAM.
• Workaround: The amount of stack required is very dependent on the application, and what features of the library it chooses to use. Obviously more intensive, demanding tasks may not be possible on more limited, constrained devices, so we recommend designing for the limitations of the target device, or choosing a device suitable for your application.
• Reported Issue: ARMmbed/mbed-os-example-tls#14

DTLS renegotiation checks also compares record epoch value

• Description:
  The TLS renegotiation routines are executed after the DTLS record sequence number for incoming or outgoing messages has exceeded a user-defined period. According with the RFC 6347 Section 4.3.1 the record sequence is an 6 byte unsigned integer, but the mbed TLS function ssl_check_ctr_renegotiate() compares 8 bytes. The additional 2 bytes correspond to the record epoch value, which may result in the incorrect execution of the renegotiation routines.
• Workaround: There is no known workaround for this issue.
• Reported Issue: Mbed-TLS/mbedtls#687

This is the release note for mbed OS 5.2.0, summarizing the major enhancements in this version.

You can find the mbed OS 5.2.0 release on GitHub.

About this release

This release builds on the significant enhancements that came in mbed OS 5.1 to add the following headline features:

• WiFi SoCs and Modules – mbed OS now supports flexible integration for different SoC, Module and Network Processor WiFi architectures, opening up fully integrated platforms as development targets. As part of this work, the IP stack has also been upgraded to the latest LwIP version (2.0), bringing support for both IPv4 and IPv6 to Ethernet and WiFi targets.

• Hardware Entropy – mbed OS now supports integration of Hardware Entropy sources, essential for strong platform security. Partners with targets containing True Random Number Generators (TRNGs) have already been integrating support so developers will be able to automatically take advantage of enhanced security.

• Memory Profiling - mbed OS core components and tools have received a number of enhancements to allow memory footprint tracking and analysis. This includes runtime tools for tracking of dynamic memory utilisation and heap information, and stack checking to trap stack over-runs.

mbed OS 5.2 also extends target support to over 60 target platforms.

The following sections provide more details of these and other changes in this release.

Core

An Events library is now part of the core platform, providing simple primitives for scheduling one-time or repeating events. The library can act as a drop-in scheduler, provide synchronization between multiple threads, or just act as a mechanism for moving events out of interrupt contexts.

We have added dynamic memory profiling features, allowing tracing the maximum heap usage at runtime, as well as invoking callbacks on each memory operation for more sophisticated annotation. Statistics, including current and maximum bytes allocated and the number of allocations, give visibility of the dynamic memory behavior that can be used in test regression scripts, alongside the existing static memory footprint analysis information.

Security

A portable HAL adds support for strong hardware entropy sources such as on-chip True Random Number Generators (TRNGs). These are used as part of the entropy pool the security functions of mbed OS rely on, ensuring each platform uses the maximum hardware-based security it can provide.

Cipher-based Message Authentication Code (CMAC) support is added, and used in the mbed OS Thread stack.

The version of mbed TLS integrated within mbed OS has been upgraded to the latest version (2.4.0). For more details, see the mbed TLS 2.4.0 release note.

Connectivity

We have introduced support for different WiFi hardware architectures, enabling mbed OS to run on integrated WiFi SoCs and modules as well as work with companion WiFi network processors. This provides hardware design flexibility, and opportunities for significant BOM and complexity reduction, by running mbed OS on the WiFi modules themselves.

The developer-facing WiFi APIs use the existing mbed OS socket interfaces (used by all IP networking) and network control features. The APIs bring up an interface, including setting the security credentials, scanning for available network access points and to read the signal strength (RSSI) for the current active connection.

This release introduces support for the u-blox ODIN-W2 integrated WiFi module. We are actively working with a number of other WiFi partners that will be introducing support for their WiFi targets in forthcoming patch releases.

The core IP stack used in mbed OS for Ethernet and WiFi has been upgraded to LwIP 2.0, bringing support for both IPv4 and IPv6. This complements our mesh networking stack, already optimised for providing 6LoWPAN and Thread networking support for 2.4GHz and Sub-GHz 802.15.4 radios.

Services

The mbed Device Connector Client is now delivered as a separate module that will be updated as new mbed device management services are introduced.

Tools and workflow

The mbed CLI tool has had numerous updates and improvements. For more details, see the mbed CLI repository.

The tools now support toolchain profiles, in particular to enable simple debug and release configurations.

The Online IDE now supports git and GitHub repositories, so you can use both mercurial and GitHub distributed version control systems.

The export mechanism supporting project generation for different toolchains and IDEs has been redeveloped to be more versatile and scalable, and now uses CMSIS-Packs for target information. When exporting to MDK and IAR, the corresponding target CMSIS-Packs must be available. Known issues include limited target coverage, needing additional configuration steps in IDEs to have projects fully functional, and exporters for Make may have linking errors where archives are used. We will be working with our silicon and tools partners to improve target coverage and project generation in future patch releases.

mbed Enabled

The mbed Enabled program continues to provide compliance criteria and technical requirements for boards, on-board interfaces and end products. It is unchanged for mbed OS 5.2, but we expect to introduce stricter requirements for Hardware Entropy support in future releases.

The following resources are available:

• The mbed Enabled requirements documents.
• The mbed Enabled application form.

Targets

Thanks to our partners’ hard work, mbed OS 5.2 has been extended to support over 60 targets.

We will continue to add new targets in our bi-weekly releases as partners introduce support. If you are a partner, please see details in the Partner Portal.

Known Issues

• UBLOX_EVK_ODIN_W2 - mbed-os-example-client - no connection established when using WiFi.
• ARM_BEETLE_SOC does not support IAR and uVision export.
• ARCH_PRO does not flash in uVision (missing flash algorithm).
• NUCLEO_F401RE export for uVision is not supported.
• UBLOX_EVK_ODIN_W2 - The WiFi driver on u-blox ODIN-W2 enables a range of weak cryptographic primitives in mbed TLS to support legacy protocols. This can make the TLS connection vulnerable too, and could be subject to a downgrade attack. It is therefore not recommended to use mbed TLS on this platform for production use.

Getting Started

To get started with this release, see the Handbook.

We are pleased to announce the mbed OS 5.1.5 release is now available.
