We are pleased to announce the Mbed OS 6.7.0 release is now available.

Summary

There is no major new functionality introduced as part of this release, but some of the enhancements we've made to existing functionality have changed APIs, so as per semantic versioning, we've incremented the release version.

The full details are below but in summary we've introduced the following changes;

  • Further evolved the Mbed CLI 2 tools by adding support to build greentea tests using CMake
  • Added the Arduino Portenta H7 as a supported target
  • Add support for the ST Microelectronis BlueNRG_2 BLE Component

Migration Guide

This section lists specific changes which are part of this release and may
need special attention.

CMake: Add CMake support for netsocket greentea test

14101

Summary of changes

  • Added CMakeLists.txt file to every test suite under the netsocket test so that it can build via CMake command

CMake: Add CMake support for events greentea test

14095

Summary of changes

  • Added CMakeLists.txt file to every test suite under the events so that it can build via CMake command

CMake: Add CMake support for rtos greentea test

14094

Summary of changes

  • Added CMakeLists.txt file to every test suite under the rtos so that it can build via CMake command

CMake: Add Support for hal greentea test

14093

Summary of changes

  • Added CMakeLists.txt file to every test suite under the hal so that it can build via CMake command

Update events period method to check for invalid values

14087

Summary of changes

The period method currently allows any ms value:
positive, negative and zero.
A negative value means dispatch a non periodic event. ie just once.
0 is unspecified behaviour.
This commit forces the user to use either positive periods or a new constant, non_periodic
and should any other value be provided will default to non_periodic.
A Greentea test case is also provided to check this works as
expected.
I'm classifying this as a feature change rather than major because allowing a zero value was actually a bug.

Impact of changes

If the user provides a 0 value this will now behave differently. Previously it would have run for a period of
time as if this was an indefinite event before eventually (with a timer wrap) have unspecified behaviour.
Now the event period will default instead to non periodic.
To specify a non periodic event a user could previously use any negative value. Whilst this will still work (due a default
being set on invalid values), the user is encouraged to use the new constant, 'non_periodic' to show that this is what was
intended.

Migration actions required

Use periods that are > 0ms or non_periodic constant.

CMake: Add CMake to platform greentea test

14072

Summary of changes

  • Added CMakeLists.txt file to every test suite under the platform so that it can build via CMake command
  • Added the CMake Macro mbed_greentea_cmake_macro with configurable arguments TEST_NAME, TEST_INCLUDE_DIRS, TEST_SOURCES, TEST_REQUIRED_LIBS so that it can be used across all the greentea test suite by passing their includes, sources required libraries.
  • Added CMake macro MBED_BAREMETAL_GREENTEA_TEST which can ON/OFF via CMake command-line argument at the configuration time to select/unselect baremetal greentea test

CMake: Create mbed-greentea library

14061

Summary of changes

The greentea framework provides all the infrastructure for the test suite to execute in the target like greentea-client, unity, utest so created the mbed-greentea interface library which binds all these framework sources, and all the test suite needs to add mbed-greentea lib into their target_link_library

CMake: Add CMake to drivers greentea test

14060

Summary of changes

  • Added CMakeLists.txt file to every test suite under the mbed_drivers so that it can build via CMake command

Add std::span implementation for cxxsupport

13881

Summary of changes

Adds std::span implementation to cxxsupport folder in namespace mstd.
See discussion in #13868.

Add Arduino Portenta H7 as target

13826

Summary of changes

This PR series introduces the support for Arduino Portenta H7 .
The patchset has been split into independent PRs for an easier review.

Impact of changes

Except the standalone TARGET_PORTENTA* content, some other files have been touched (all of them in separate commits).
In particular, COMPONENT_WHD has been made generic (any mbed target implementing SERIAL_FC can now compile it) but this could impact PSOC6 targets which used to configure it via Cypress HAL.

Support to BlueNRG_2 BLE component

13246

Summary of changes

Add support to BlueNRG_2 BLE Component

Known Issues

We publish Mbed OS as a collection of modules on GitHub. Issues are raised in the specific repositories and then tracked internally. The purpose of this section is to provide a single view of the outstanding key issues that have not been addressed for this release. As such, it is a filtered and reviewed list based on priority and potential effect. Each item summarizes the problem and includes any known workarounds, along with a link to the GitHub issue (if applicable). We welcome any comments or proposed solutions.

For more information about an issue, contact us on the forum.

TLS: IP addresses in the X.509 certificate subjectAltNames

  • Description: Parsing IP addresses in the X.509 certificate subjectAltNames is not supported yet. In certificate chains relying on IP addresses in subjectAltNames a BADCERT_CN_MISMATCH error is returned.
  • Workaround: merge branch https://github.com/ARMmbed/mbedtls/tree/iotssl-602-san-ip into your copy of Mbed TLS before building the application. It is still in EXPERIMENTAL stage, use it on your own responsibility!
  • Reported Issue: Issue reported by a customer in email.
  • Priority: MAJOR

TLS: Mismatch of root CA and issuer of CRL not caught

  • Description: The x509_crt_verifycrl() function ignores the CRL, when the CRL has an issuer different from the subject of root CA certificate.
  • Workaround: Make sure that the issuer of the CRL and the root CA certificate's subject are the same before passing them to x509_crt_verifycrl().
  • Reported Issue: Reported by a partner.
  • Priority: MAJOR

TLS: Self Test Failure with Some Hardware Accelerators

  • Description: Most HW acceleration engines (if not all) require the parameters to be from contiguous memory.
    All the self tests use test vectors that are defined in the .bss section, which means these are not contiguous. This causes the self test to possibly fail, when implementing HW accelerated engines.
  • Workaround: There are no known workarounds.
  • Reported Issue: Reported by the development team.
  • Priority: MAJOR

TLS: Hardware-accelerated hash creates CBC padding oracle in TLS

  • Description: The current countermeasures against CBC padding oracle attacks in Mbed TLS call a low level internal API. The implementation of this API might not be possible with the hardware accelerator API and even if it is, the timing might still have detectable differences. The lower level API is called out of sequence and accelerators that are not aware of this might crash.
  • Workaround: Keep MBEDTLS_SSL_ENCRYPT_THEN_MAC enabled in mbedtls/config.h and enable the Encrypt-then-MAC extension (RFC7366) on the peers side.
  • Reported Issue: Reported by the development team.
  • Priority: MAJOR

Crypto: Mbed OS ATECC608A example fails to build with IAR

  • Description: The current ATECC608A secure element example fails to build with the IAR toolchain. The Microchip-provided cryptoauthlib library does not build with IAR.
  • Workaround: Use a different toolchain, like GCC_ARM.
  • Reported Issue: MicrochipTech/cryptoauthlib#116
  • Priority: Minor

Tools: Error when running mbed test --compile/run list

  • Description: The error, "pkg_resources.DistributionNotFound: The 'mbed-ls==1.*,>=1.5.1' distribution was not found and is required by icetea, mbed-flasher" is observed when running the command "mbed test -m K64F -t ARM --icetea --compile-list -vv".
  • Workaround: None
  • Reported Issues: #8064
  • Priority: Major

Wi-SUN Hardfaults with IAR compiled image with Mbed OS 5.15.0

  • Description: Mesh Wi-SUN FAN may HardFault in rare occasions with IAR8 compiled binaries during initial network connection.
  • Workaround: The workaround is to use other compilers.
  • Reported Issue: IOTTHD-3898
  • Priority: Major
