mbed-os-5.11.3

We are pleased to announce the Mbed OS 5.11.3 release is now available.

Summary

In this release we have added target support for Quectel M26 GSM/GPRS module and C030-R412M,

We have added fixes for the following reported issues:

• 9138 Can't execute OS2 tests in ARM if default_toolchain is uARM
• 85 Len vs amount check
• 9400 tests-mbedmicro-rtos-mbed-systimer to tune ?
• 9426 NUCLEO_H743ZI: iar export failing
• 9281 lfs_emubd.c needs to be ignored?
• 9513 Occasional hard fault when using the mbedtls entropy function in parallel threads (K64F)

Support has been added for:

• Nanostack on KW41Z
• An updated PSA binaries importer for FUTURE_SEQUANA_PSA
• FLASH on TARGET_MAX32620C MCU, MAX32620FTHR and SDT32620B
• CAN on STM32H7
• TICKLESS on NUCLEO_H743ZI
• QSPIF as default storage for LPCXpresso546XX

Important notes:

• A folder path fix for KVStore FILESYSTEM configuration and default configuration (under SD component) has been added. Previously the folder path was the constant "kvstore". This has been fixed to now behave correctly by taking the value from the configuration store. Users will now need to ensure they have the correct values in the configuration store.

• The IAR heap size for STM32L496xG has been increased

• A problem was identified where ther FlashIAP driver would fail during write actions due to HW limitations. A fix has been added to retry a few times until the write is successful.

• There was a random issue where a device would not boot. This was found to be due to the pre-main check of error_reboot_count being applied repeatedly on every boot. This meant that once the reboot limit was hit, every subsequent reset would halt before main, until something managed to clear or corrupt the error context. This has been fixed by setting the is_error_processed flag before halting, so that when an external agent resets the device while halted, the error is not reported (which would cause the device to halt again).

There are also a number of other fixes and code improvements.

mbed-os-5.11.2

We are pleased to announce the Mbed OS 5.11.2 release is now available.

Summary

In this release we have added target support for NUCLEO_H743ZI, GD32_E103VB and GD32_F450ZI.

We have added fixes for the following reported issues:

• 8567 Equeue unchain bugs
• 8913 Build of NUCLEO_F030R8 fails when DEVICE_SERIAL=0
• 8903 Realtek_RTL8195AM is printing a lot of traces
• 9196 ESP8266 CTS/RTS fails in stop_uart_hw_flow_ctrl()
• 9075 K82F QSPI test fails intermittently
• 9216 Defining MBED_SLEEP_TRACING_ENABLED caused error
• 9266 Astyle in travis doesn't use .astyleignore
• 9255 FLASHIAP component tests failed
• 9207 MCU_LPC546XX - breaks on master
• 9272 Block device test : skip multi thread part in case of small RAM

Support has been added for:

• PSA APIs on Pelion supported boards
• a bootloader on the DISCO_F469NI

There have also been some updates to improve the quality of the documentation.

Important notes:

• There was an issue with the internal KVStore, identified after the 5.11 release. The fix for this
  required changes which would normally not be accepted into a patch release. We have made an exception in
  this case due to the significant nature of the issue.

  Prior to the fix provided in, 9156,
  the space left for the internal TDBStore (when working in the default internal configuration) was allocated from
  the sector following the end of the application until the end of flash. While this worked, it was problematic if the
  application would have crossed the sector boundary after an update. This PR leaves the application a couple
  of sectors to grow at the expense of the allocated storage (if they are available, which is the likely case).

  The fix is defined as a breaking change, even if not a typical one: Boards that use the default internal
  configuration will lose the storage content after the upgrade (as the internal storage start will move forwards).
  Two boards will be affected: K66F and FUTURE_SEQUANA_M0_PSA. Non default configurations won't be
  harmed.

• The device key in versions before 5.11.2 may have been insecure as the TRNG may have unknowingly failed.
  This issue has been addressed in this release by 9278 DeviceKey: [Security Fix] Generated ROT-key is still used when TRNG fails.

There are also a number of other fixes and code improvements.

mbed-os-5.11.0

We are pleased to announce the Mbed OS 5.11.0 release is now available.

Summary

Mbed OS 5.11 adds secure sockets, so your Mbed OS applications can securely connect and send data to any cloud or server through any TCP-based protocol. It also provides advanced storage solutions for IoT devices to encrypt external memory, and a storage stack that allows using internal flash for firmware updates. Mbed OS 5.11 also supports enhanced device statistics APIs for capturing key information, such as network statistics and advanced system information.

This release includes many minor fixes and enhancements and brings support for 157 target development boards.

Operating system

Secure sockets

With secure sockets, your Mbed OS applications can securely connect and send data to any cloud or server through any TCP-based protocol. By introducing native secure sockets to Mbed OS we enable TLS functionality in the background, simplifying secure connections. For more information, please visit secure sockets.

Advanced storage solutions for IoT devices

Encrypted and authenticated storage

Encryption and authentication for external memory provide greater protection against physical attacks against IoT devices. This adds significant value to products that do not trust the PCB, and which could be tampered with, making security comparable to being on-chip. For more information, please visit storage.

Storage stack for internal memory

Microcontrollers now provide more performance and bigger internal memory, offering new opportunities. In Mbed OS 5.11, we allow businesses to use internal MCU memory to store configuration and firmware images, and reduce the cost of the bill of materials for IoT devices. For more information, please visit storage.

Enhanced device statistics APIs

Pulling valuable stats from IoT devices is key for any business deploying these devices, and is an important initiative driven by Arm. The intension is to collect data from embedded devices and (in the future) predict their behaviour using machine learning.

Mbed OS already implements a Device Statistics API to collect data such as thread info, CPU usage, memory info, and system info. In Mbed OS 5.11, we've added advanced device stats such as network stats, advanced system Info, and errors info. For more information, please visit statistics.

Internal RAM marked as execute never

Many Remote Code Execution (RCE) exploits attempt to use buffer overflows in the stack or the heap to write exploit code into memory, and then cause the system to execute that code. If the address where the exploit was written were marked execute never, this exploit code would not be executable. With Mbed OS 5.11 on supported targets, all RAM space is marked as execute never by default. For more information, please visit MPU management.

Crash reporting for critical fault with automatic reboot

When the system encounters a fatal crash (for example, a hard fault), we capture information such as register context and thread info, as these are required to debug the issue. This information is usually dumped over the serial port, but when the crash happens in deployed devices, there will not be any serial port enabled or logged, so a different mechanism is needed to record and report this data. With the crash-reporting feature of Mbed OS, the system reboots without losing RAM contents, and we can send this information over a network or other interfaces to be logged, or even write to the file system if required. For more information, please visit error handling.

Connectivity

Support for extended and periodic advertising in GAP (BLE stack)

Extended advertising uses multiple physical layers and spreads the payload across many packets to support much larger payloads than normal. In this scenario, advertising is split across primary advertising on the advertising channels and secondary advertising on channels normally used for sending data to connected devices. Similarly, if the controller supports periodic advertising, you may use it to send changing data to many peers. Each peer needs to scan the advertisements on the primary channels and create a sync with the periodic advertisement it's interested in. For more information, please visit GAP.

Cellular stack updates

The LoRaWAN stack was updated to version 1.1, which includes support for secure device provisioning through a Join Server, new security primitives, handover roaming, and optimizations for communication from the network to the device. For more information, please visit LoRaWAN-11.

In addition, we added support for AT-mode TCP over cellular for selected modules

• Quectel BG96
• Quectel BC95 (used in the WISE-1570 module)
• Gemalto cellular modem driver.

Security

Update to Mbed TLS

Mbed OS 5.11 includes Mbed TLS 2.15.1, which introduces the Mbed Crypto library and other new features. For more information, please visit, mbedtls.

Mbed Crypto APIs

The Mbed Crypto library is a reference implementation of the Platform Security Architecture (PSA) Cryptography API. Therefore, the library's API documentation is the PSA Cryptography API specification. Arm's PSA is a holistic set of threat models, security analyses, hardware and firmware architecture specifications and an open source firmware reference implementation. PSA provides a recipe, based on industry best practices, that allows security to be consistently designed, at both a hardware and firmware level. The PSA Cryptography API provides access to a set of cryptographic primitives. It has a dual purpose: It can be used in a PSA-compliant platform to build services, such as secure boot, secure storage and secure communication; and it can be used independently of other PSA components on any platform. The Mbed Crypto APIs are currently in development. For more information, please visit mbed-crypto.

PSA Secure Partition Manager

We have added PSA compliant process separation for the Future Electronics Sequana dual-core v7-M platform. The process separation is enforced with the Secure Partition Manager (SPM), which uses hardware on the device to provide RAM and Flash isolation between the two cores. It also implements the PSA Firmware Framework Inter-Process Communication (IPC) API, which allows the cores to communicate with each other. More information about Sequana is available at Future-Sequana. For more information about SPM, please visit SPM.

Targets and tools

Thanks to our Partners’ hard work, Mbed OS 5.11 added 12 new target platforms for a total of 157. We’ll continue to add targets in our biweekly patch releases as partners work with us.

The official Arm Mbed OS compiler has been update from ARM CC 5.06 update 3 to ARM CC 5.06 update 6, which includes new bug fixes.

Testing and improvements

Support Ethernet for Fast Models

Arm Fast Models are software models of Arm cores, subsystems, peripherals and so on. Mbed OS has enabled working with Cortex-M family Fast Models. You can run and test Mbed OS and its applications on the software model instead of the hardware. In Mbed OS 5.11, we now support Mbed OS sockets examples with Fast Models Ethernet. For more information, please visit Fast Models.

Continuous integration framework

We designed Mbed OS to significantly reduce the cost and time of embedded software development by providing production-quality toolset and code. We are committed to delivering high-quality code working across all supported boards and platforms. To ensure all the features of code meet our quality control requirements, we have built an automated testing environment and processes that perform rigorous testing on every line of code. The continuous integration framework is a highlight of our testing framework - it ensures that every new feature and change in Mbed OS is tested:

• For every new feature, we create tests that we then deliver to our Partners. For every board to be Mbed Enabled, we need our Partners to successfully conduct these tests.
• Partners must test the changes on their boards before submitting pull requests (PRs) on GitHub.
• The Mbed OS gatekeepers manually review the code of each PR to ensure it meets our coding guidelines and code standards.
• Once approved by the gatekeepers, the code goes through the automated test infrastructure, which tests across multiple platforms using three toolchains: IAR, ARM and GCC.
• During the testing phase, we select the combination of boards and devices that support a variety of peripherals, MCU cores and features for maximum coverage.
• To ensure the Mbed OS code is compatible with all IDEs, we test that the code can be exported properly to all the compilers.
• We merge a PR only if all the above procedures are successful.

For Mbed OS 5.11.0, our testing included:

• Total test time of 42,372 hours on development boards.
• 30 new test cases since the Mbed OS 5.10.0 release. These test new and existing features and bring the total number of tes...

mbed-os-5.10.2

We are pleased to announce the Mbed OS 5.10.2 release is now available.

Summary

In this release we have added support for TMPM4G9, RapidIoT and Laird BL654.

We are currently focusing on improving the quality of our documentation, so there
are a number of documentation fixes in this release and upcoming ones.

There are a number of reported issues that we have fixed:

• A 4/8 byte alignment error in the device scatter files.

• On the STM32F1 family of devices the set_time function was not setting the time correctly.

• On STM32 devices extra power consumption was observed when in STOP mode. This was due to
  the HSI clock being enabled in that mode, whereas only the LSE clock should be enabled.

Mbed-coap has gone through a couple of version updates:

• Version 4.7.0 brings:
  A new function that can be used to clear the received blockwise payloads, for example in
  the case of a connection error.

  Silencing the compiler warning when CoAP duplicate detection is enabled.

• Version 4.7.1 brings:
  A new re-scan routine whch is called when blockwise message sending times out, preventing
  a hard fault.

We have added:

• us ticker support for TMPM066 and TMPM46B
• RTC support for MIMXRT1050_EVK
• missing IAR exporters for the STM32 family
• ADC support for DISCO_L496AG
• an ADC update for internal channels on STM32L1 devices.
• flash support for KL43Z, KL82Z, KW41Z and K22F.

There are also a number of other fixes and code improvements.

mbed-os-5.10.0

We are pleased to announce the Mbed OS 5.10.0 release is now available.

Summary

In Mbed OS 5.10, we are improving the firmware update user experience. Mbed OS provides integrated firmware over-the-air (OTA) update capability enabled by Pelion Device Management. Mbed OS now makes it seamless and provides secure and flexible IoT firmware update and device management capabilities right from Arm Mbed CLI tool itself. Bluetooth Low Energy (BLE) is quickly becoming the IoT connectivity protocol of choice for a variety of use cases. In Mbed OS 5.10, we are launching Arm Mbed Cordio stack, the world’s first open-source, fully-qualified and production-ready BLE software stack that supports BLE 5 and gives developers even more flexibility in developing new IoT solutions with BLE connectivity.

Security is the most important challenge for the IoT developers. Mbed OS is supporting Arm V8M which has built in Trustzone functionality and laying the foundation for you to build highly secure devices. In Mbed OS 5.10, we are now supporting the Nuvoton M2351 based on the latest ARM V8M core. We are also integrating storage components, such as SPIF, SD and FlashIAP block devices, into the Mbed OS repository to simplify the use of storage components.

In addition, this release contains many minor fixes and enhancements and brings support for 145 target development boards. In the release note below, we summarize some of the key updates to Mbed OS that are part of the Mbed OS 5.10.0 release.

Core OS

Enhancing the user experience for firmware OTA updates

Firmware OTA updates are critical for IoT devices to ensure that the IoT device can be maintained throughout its lifecycle. Firmware OTA updates can significantly increase your device’s lifespan. If a device cannot update its firmware over the air, you must go to the field where the device is deployed and update its firmware, which is expensive and not scalable. Mbed OS supports firmware updates enabled by Pelion Device Management and provides flexible, secure and simple IoT device management for any device. It enables the provisioning and connection of IoT end nodes with cost-effective, secure and reliable software updates, ensuring a long product lifetime. In Mbed OS 5.10, we are simplifying the user experience of doing firmware updates. This enhancement means you can seamlessly enable firmware update capabilities in your IoT device. Using Mbed CLI, you can perform firmware updates to your device in fewer commands. You can also prepare firmware updates for one or multiple devices. For more information, please refer to our documentation about updating devices.

Support for ARMv8-M with Nuvoton M2351

Mbed OS supports building highly secure IoT embedded solutions based on the ARMv8-M platform. The most significant enhancement in the ARMv8-M architecture is the inclusion of the TrustZone security extension, a technology that adds a new dimension of security control and allows multiple security domains within a single processor system. This results in enhanced security and simplified development. TrustZone enables a “secure world” that keeps important data, such as private keys or pre-shared keys, isolated from the main operating system and apps. Mbed OS 5.10 supports Nuvoton M2351, based on the Cortex-M23 processor. Mbed OS also provides all necessary tools to support building and deploying both secure and nonsecure sides of application. Please see our tools documentation for more information.

Integration of storage components inside Mbed OS

Storage functionality is an essential requirement for building IoT devices that store data, firmware images and credentials on external MCU memory. Throughout the past few Mbed OS releases, we have developed functionality to support many different types of external memories, such as SPI flash and SD card. The storage drivers were developed as external components to allow continuous development and maturity of those drivers before bringing them inside Mbed OS. In Mbed OS 5.10, we are moving the SD, SPI Flash (SPIF) and FlashIAP drivers into Mbed OS. Integration of storage components into the Mbed OS repository makes it easy to use them and allows the simple add-on of default block device and default file system functionality. We added SD, SPIF and FlashIAP block devices under the new component label configured in target.json. Any board with an SD or SPI Flash component enabled has a default block device and file system. For more information, please visit the SDBlockDevice, SPIFBlockDevice and FlashIAPBlockDevice API documentation.

Quad SPI (QSPI) block device driver

With the cost of memory going down rapidly and performance on MCUs increasing every day, devices are storing more data than ever before. QSPI enables faster data transfer compared to traditional flash and used with components such as connectivity modules, displays and others. With QSPI, Mbed OS can communicate with external memories much faster than through SPI because the communication can be up to four lines between the host and a device. We are releasing the QSPI block device driver to enable NOR-based QSPI flash devices that support SFDP. For more information, please visit the QSPI documentation.

Connectivity

Arm Mbed Cordio Bluetooth Low Energy (BLE) stack

Production-ready open source BLE software stack: BLE is quickly becoming the Internet of Things (IoT) connectivity protocol of choice for a variety of use cases, including smart lighting, smart cities and asset tracking, where low cost, power consumption and a small footprint are fundamental requirements. According to the 2018 Bluetooth Market Update, there will be more than 5 billion Bluetooth device shipments by 2022, with 97% of them containing BLE technology. The advances in Bluetooth 5 technology, along with the introduction of Bluetooth Mesh, are driving new market opportunities across building automation, sensor networks and other IoT solutions.

In Mbed OS 5.10, we are adding Arm Mbed Cordio BLE stack to make it easier and more secure for organizations and developers to add BLE to their IoT devices to drive adoption levels to new heights. Arm Mbed Cordio BLE stack is the world’s first open-source, fully-qualified and production-ready BLE software stack, which gives developers even more flexibility in developing new IoT solutions with BLE connectivity. Using Arm Mbed Cordio BLE stack, you can innovate through Bluetooth 5 which supports 2x the data rate, 4x the range and 8x the broadcast capability compared to the previous version, Bluetooth 4.2.

Near field communication (NFC) card emulation mode support

NFC is a short-range radio technology that enables use cases such as contactless payments, access control and device pairing. We are enabling the card emulation mode in Mbed OS 5.10 through an NFC controller or NFC EEPROM. With Mbed OS 5.10, it is now possible to create NDEF messages that can contain device identification, pairing or sensing data. For more information, please visit the NFC API documentation.

Default network interfaces

Mbed OS 5.10 targets that provide network connectivity also provide a default network interface. This can be Ethernet, Wi-Fi, mesh or cellular. Using a default interface allows you to port applications to different targets and connectivity options. Applications no longer require libraries, such as Easy-connect, to be portable.

Refactored Socket API

This release refactors the Mbed OS Socket API by bringing it closer to the POSIX equivalent. The new design contains an abstract socket interface that applications can use directly. Casting Socket pointers back to TCPSocket or UDPSocket is no longer necessary. For most of the applications, these changes are not noticeable because the TCPSocket and UDPSocket classes still emulate previous behavior. The new design also renders the TCPServer API unnecessary, moving its functionality directly into TCPSocket itself. The legacy TCPServer class still exists and is fully functional.

Connectivity stack always builtin

Applications are no longer required to specify FEATURE_NANOSTACK, FEATURE_LWIP or FEATURE_COMMON_PAL to use any of the connectivity stacks that Mbed OS supplies. Those are always included in the build. This change does not increase any flash use because the linker can drop any unused functions.

Connectivity drivers

For easier integration and testing, this release includes some connectivity drivers for external modules, such as the ESP8266 Wi-Fi driver, AT86RF233 driver and MCR20A driver. Now applications using those drivers receive any applicable bug fixes every time they update Mbed OS.

Security

Update to Mbed TLS 2.13

Mbed TLS 2.13.0 introduces several new features improving our support for DTLS over low-bandwidth, high-latency networks with high packet loss.

Specifically:

• Support for fragmentation of outgoing handshake messages. This allows the use of Mbed TLS across networks with datagram links with MTUs as low as 512 bytes, making it suitable for NB-IOT networks.

• Grouping outgoing handshake messages in a single datagram, reducing both the network load and the likelihood of reordering effects.

• Reordering handshake packets that have been received out of order, reducing the number of retransmissions necessary to complete a handshake and therefore increasing handshake efficiency and reducing network load.
