We are pleased to announce the Mbed OS 5.13.1 release is now available.

Summary

In this release we have added target support for:
MTB ublox ODIN W2 and NUCLEO-F413ZH.

We have:

• Introduced a watchdog API to detect system malfunctions and reset the system to recover from them
• Introduced an API to detect the system reset reason to compliment the watchdog functionality
• Updated ST CUBE for the STM32F0 series to v1.9.0. This brings:
  • Current ST Cube version in MBED to V1.7.0
  • CMSIS part update from 2.3.1 to 2.3.3
  • HAL part update from 1.5.0 to 1.7.0
• Replaced our BLE Nordic PAL client implementation. Issues in the GattClient logic have been fixed and previously missing GAT procedures have been implemented:
  • Discover Primary Service by Service UUID
  • Find Included Service
  • Read Using Characteristic UUID
  • Read Multiple Characteristics
  • Queue Prepare Write
  • Execute Write
• Added Flash support for STM32F0, STM32F1 and STM32F3 devices
• Enabled tickless mode on nRF52840

Important changes are:

• 10997 VSCode exporter now uses executables that are installed into the system PATH instead of absolute paths to the compiler executables.
• 10967 ESP8266 driver fix to work with older firmware version of ESP8266 module.
• 10938 K64F, STM32F429: IAR icf linker scripts modified to use dynamic heap allocation of all available memory.
• 10879 PSA Crypto APIs are now available on all Mbed OS targets.
• 10857 Watchdog API:
  • Added new HAL API: watchdog and reset_reason
  • Added new drivers: ResetReason and Watchdog
• 10824 STM32: pwmout_write: configure channel only when not already enabled
• 10794 LWIP DNS servers setting/getting fixed.
• 10776 UDPSOCKET_ECHOTEST_NONBLOCK performance improvement.
• 10757 Add support I2C 3 for target EFM32G11
• 10701 STM: replace C++ low power ticker wrapper with a low level wrapper to remove the latency limitation of the LP ticker wrapper.
• 10665 Add hardcoded Echo server defaults for Greentea socket tests.
• 10609 wait_us has been optimized for certain platforms - see us_ticker_api.h for the details of enabling optimizations on other targets. It can be optimized further if the option target.init-us-ticker-at-boot is enabled.

We are pleased to announce the Mbed OS 5.13.0 release is now available.

Summary

As IoT devices proliferate, our focus is shifting toward optimizing Arm Mbed OS to best address the use cases our customers face. In 5.13, we have reduced the number of new features we’re delivering and have instead concentrated on specific optimizations of existing features that benefit our customers.

Migration guide

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

Nanostack release for Mbed OS 5.13

10624

This release contains updates for the Mesh protocols:

• Stability improvements and bug fixes to Wi-SUN and Thread protocol.
• EAPOL (certificate-based network authentication) enabled to Wi-SUN mesh protocol.

Notes about Mesh stack maturity:

• This version of Wi-SUN stack is interoperable only with itself (development work still ongoing).
• Wi-SUN protocol is tested using functional protocol testing suites.
• Wi-SUN nonfunctional testing is performed using 40 devices connected to single Wi-SUN network.
• Thread stack is verified using protocol testing suite that includes certification test suite.

DataFlash: Change erase size to pages to reduce memory use

10478

Previously the DataFlash driver exposed the minimum erase size as blocks, which are typically 4 K. DataFlash, however, supports page erases as small as 256 B.

This change implements page erases, which lower RAM requirements for buffers.

Because this has no relation to any file system and lowers the minimum erase size, it should not cause issues with devices with existing data stored on them. However, a future format of FATFS may end up with smaller sectors by default, which would further reduce RAM requirements.

Enterprise_mode + wifi_configuraiton_api: update ODIN drivers to v3.7.0 RC1

10454

A private API is provided for ODIN_W2 target against enterprise mode.

nsapi_error_t connect(
const char          *ssid,
const char          *pass,
nsapi_security_t  security,
auth_cert_s         *cert_handle,
const char          *username = NULL,
const char          *user_pswd = NULL,
uint8_t               channel = 0);

The application is required to pass a certificate (CA cert or client cert) and key (private key) in PEM format. You are required to pass those certificates through cert_handle auth_cert_s. An appropriate security should be selected: either NSAPI_SECURITY_EAP_TLS or NSAPI_SECURITY_PEAP.

For example:

static auth_cert_s   certificates;
_wifi = new OdinWiFiInterface(true);
#ifdef EAP_TLS_TESTING
certificates.client_cert = &cert_data[0];
certificates.client_prvt_key = &cert_data_key[0];
certificates.ca_cert = NULL;
#elif defined(PEAP_TESTING)
certificates.client_cert = NULL;
certificates.client_prvt_key = NULL;
certificates.ca_cert = &ca_cert_data[0];
#endif
_wifi->connect(ssid, pass, security, &certificates, _peap_username, _peap_user_pass, channel);

Configuration API

virtual unsigned int get_config(void *setting);
virtual void set_config(void *setting, cb_uint32 value);

A description of parameters is available in https://github.com/u-blox/mbed-os/blob/0dda8c447c644cb8ee5063099ad09226a6caf746/targets/TARGET_STM/TARGET_STM32F4/TARGET_STM32F439xI/TARGET_MODULE_UBLOX_ODIN_W2/sdk/ublox-odin-w2-drivers/cb_wlan_driver_config.h

Cellular: Make AT_CellularContext::get_context() virtual

10442

Makes AT_CellularContext::get_context() virtual - overwrite-able by the individual cell module driver authors (similar to what is available for other AT_CellularContext functions, like do_connect()).

Set compilers to C++14 and C11

10427

GCC and Arm toolchain profiles now select C++14 and C11, matching IAR, and these are the tested profiles. The code base in this release should still work if profiles are set to C++98 and C99, though this is no longer tested.

Migration notes

As the default profiles now select C++14 and C11 for GCC and Arm toolchains, some applications may fail to compile because they use constructs that were valid in C++98 but are not in C++14.

IAR 8 has always operated in C++14/C11 mode, so there are no new changes for IAR users who switched to IAR 8 for Mbed OS 5.12, but these notes apply to users migrating from older Mbed OS versions that used IAR 7.

Common compatibility issues

• A space is required when a macro follows a string literal, for example in C99-style printf formats:

  uint32_t val;
  printf("val = %"PRIu32, val); // Not valid in C++11
  printf("val = %" PRIu32, val); // OK

  Without the space, C++11 interprets it as being a request for a user-defined "PRIu32-type" string literal.

• Initializer lists cannot have implicit narrowing conversions:

  uint32_t x;
  uint8_t array1[] = { x }; // Not valid in C++11
  uint8_t array2[] = { 0xffff }; // Not valid in C++11
  uint8_t array3[] = { x & 0xff }; // Not valid in C++11
  uint8_t array4[] = { (uint8_t) x }; // OK
  uint8_t array5[] = { static_cast<uint8_t>(x) }; // OK
  uint8_t array6[] = { 0xffff & 0xff }; // OK (because it's a compile-time constant that fits)

  These changes should be easy to make to existing code bases. You can find a guide to other possible breakages in C++11 at https://stackoverflow.com/questions/6399615/what-breaking-changes-are-introduced-in-c11. C++14 and C11 can cause a few extra issues.

Future compatibility issues

The register keyword is deprecated in C++14 and is removed in C++17. Some compilers issue warnings for register use in C++14, but this has been temporarily suppressed due to the prevalence of the keyword in target code. C++ code should be updated to remove the keyword as soon as possible: The warning will be reactivated after Mbed OS itself no longer triggers it.

Fallback

Mbed OS 5.13 releases should still work if compiled as C++98/C99, though this is not tested. If you have serious application compatibility issues, you should be able to switch the build profile back to the earlier language version as a temporary measure. This is likely to no longer be the case for Mbed OS 5.14.

Arm Compiler 5

Arm Compiler 5 has limited C++11 support and no C++14 or C11 support, and Arm Compiler 5 is no longer tested or officially supported. Nevertheless, Arm Compiler 5 builds have deliberately not been broken; the Arm Compiler 5 build profiles select its C++11 mode in an attempt to match the other toolchains as much as possible, but the limited support may itself cause issues. Attempts to check __cplusplus >= 201103 may activate code Arm Compiler 5 cannot actually compile. Like the other toolchains, the profile can be switched back to C++98 if necessary for now.

Continued Arm Compiler 5 support will limit the adoption of C++11 and C++14 features in the Mbed OS code base, so it is possible Arm Compiler 5 builds may stop working in an upcoming release.

Nanostack: translate errors from sendmsg

10410

Nanostack send calls return more accurate information in case of errors.

Update CMSIS to 5.5.1

10366

CMSIS updated from 5.4.0 to 5.5.1.

KVStore: Support external storage out of mbed-os tree

10355

Support external storage out of mbed-os tree in KVStore. To enable it, you need to:

1. Configure KVStore configuration parameter blockdevice to other.

2. Override get_other_blockdevice() to provide block device out of mbed-os tree.

   BlockDevice *get_other_blockdevice();

Update to LWIP 2.1.2

10353

The latest LWIP 2.1.2 released is now integrated with Mbed OS. The new LWIP release has improvements in following areas:

-IP4 routing.
-IP6 scopes and zones.
-DHCP6.
-ND6.
-TCP.
-Sockets.
-Binding network interfaces to sockets.

The LWIP changelog contains detailed changes

Mbed OS dedicated patches were applied to the new LWIP version.

Multihoming was refactored due to the new socket-interface bind implementation.

Add option to disable default UART console

10328

A new configuration option, target.console-uart, allows default serial console functionality to be deactivated, either because the target has serial but no console, or to save power/memory by not using the console.

Remove FEATURE_STORAGE and all underlying deprecated features

10258

Remove FEATURE_STORAGE and all underlying deprecated features: cfstore, flash-journal and storage-volume-manager.

Mail/MemoryPool: blocking alloc

10225

Mail and MemoryPool now provide blocking forms of alloc calls that can sleep the thread until a memory block is available.

Cellular: CellularContext must provide access to CellularDevice

10210

When using NetworkInterface::get_default_instance(), the application gets handle to CellularInterface, which is actually CellularContext derived from CellularInterface. The application also needs to handle CellularDevice to open other interfaces.

Assembler atomics

10147

We have:

• Separated atom...

We are pleased to announce the Mbed OS 5.12.4 release is now available.

Summary

No new targets being added in this release.

Important changes are:

10520 Permit non-TrustZone ARMv8 build

• Non-TrustZone ARMv8 targets now supported (core must be set to Cortex-M33 rather than Cortex-M33-NS).

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

We are pleased to announce the Mbed OS 5.12.1 release is now available.

Summary

We have added support for two new targets in this release, MTB ublox ODIN W2 and NUCLEO-F413ZH.ST CUBE for the STM32F0 series has been updated to v1.9.0.
This brings:

• Current ST Cube version in MBED: V1.7.0
• CMSIS part update from 2.3.1 to 2.3.3
• HAL part update from 1.5.0 to 1.7.0

Our BLE Nordic PAL client implementation has been replaced. The previous implementation was found to contain a number issues deep in the GattClient logic (improper queueing and order ofoperations). It was deemed more efficient to re-write the implementation than try to patch the previous version.
As well as fixing issues, the re-write has the added benefit of including all the previously missing GAT procedures:

• Discover Primary Service By Service UUID
• Find Included Service
• Read Using Characteristic UUID
• Read Multiple Characteristics
• Queue Prepare Write
• Execute Write

We have also added Flash support for STM32F0, STM32F1 and STM32F3 devices, and enabled tickless on nRF52840.

There are also a number of bug fixes and test enhancements.page, which provides reference links and details of our support channels.

10118 Selectively append changes to exported config files

Not tested on windows or python 2.
Uses .splitlines(), and newlines should be correctly handled by the file read and write functions.

10106 Update manifest tool to version 1.4.8 and install it from pypi

10102 Remove fuzzywuzzy dependency

10081 Cellular: call AT+CGEREP after sim is ready

AT+CGEREP call was made before sim was ready and it was failing in most modems.
Now call is made after sim is ready.

9964 Add imports of basestring for python 3

9905 Tests: check if recv returned too much data

9904 Handle oversized packets in tcp and udp socket tests.

9896 wait_us without usticker

Some targets have no usticker. Fallback to use busy loop wait_ns() for cases like this.

9837 Cellular: CGACT not supported in coming firmware in BG96
Change API CellularNetwork::is_active_context to take more parameters to reduce copy-paste code.
API can be use in old way as parameters have default values.
Change CGACT to QIACT in case as BG96 module. Reason is that in upcoming firmware versions only QIACT is supported. Current firmware versions do support both commands.

9814 Adding NUCLEO_WB55RG support

Known Issues

Summary of release

Mbed OS 5.12.0 brings support for Platform Security Architecture (PSA) to truly secure your data end-to-end. The release is supported in Mbed Studio Beta, providing a seamless development and debugging experience. We also included the first open sourced Wi-SUN stack for Field Area Networks based on 6LoWPAN and IEEE 802.15.4 technologies, and our new USB device stack supporting multiple device classes. Finally, we introduce a new Mbed OS profile called bare metal, which targets memory constrained devices.

This release also includes fixes, new versions of various components and updates to supported compiler versions.

Notes for specific pull requests

9920 Update Mbed TLS for 5.12 release to Mbed TLS development HEAD
This release of Mbed TLS includes:

• Integration of the PSA Crypto API sufficient to support Pelion Client.
• RAM optimizations to reduce RAM usage during TLS handshakes when using X.509 authentication. This reduces the overall RAM required by Mbed TLS.

9898 Cellular: fix connect-disconnect sequence called many times
Removed API get_connection_status() from CellularNetwork. This was left accidentally after refactoring. It wasn't giving correct states after refactoring. The application should use CellularContext::get_connection_status, instead.

9864 BLE: Cordio host upgrade
Upgrade of Cordio host to new version (from 2.4 to 19.02). This should not impact users and be an in-place upgrade. Replace compiled Cordio controller libs with sources - no functional change and no impact on users.

9851 feat: add support for .obj files in memap

• A brief description of changes introduced
  Add support for .obj files in memap tool.
• An analysis of effects: components affected, potential consequences for users and reasons for the addition or change.
  Affects tools component, behaviour doesn't change for existing users. This adds support for using the memap tool for CMake/gcc-arm-none-eabi builds (and maybe others too).
• Migration guidance: actions for updating the current code. Please include code snippets to illustrate before and after the addition or change.
  N/A

9838 Nanostack release for Mbed OS 5.12

• Initial version of Wi-SUN mesh stack.
• Improvements and bug fixes to Thread and 6LoWPAN ND protocol stacks.

9813 BLE: Cordio build time configuration through mbed_lib.json
This doesn't remove the old Cordio stack config file and merely sits on top, so it will not introduce any unexpected changes. If users modified the cfg files themselves (in features\FEATURE_BLE\targets\TARGET_CORDIO\stack\cordio_stack\ble-host\sources\stack\cfg), they will have to resolve the conflict.

9812 Add wait_ns API

• wait_ns() API added for <10us small software-loop based delays.

9808 IAR 8 feature branch merge
Updating the IAR toolchain version to IAR 8.32.

9804 Provide an option to disable writing developer certificate
It is possible now to disable writing developer certificate to mbed_cloud_dev_credentials using an option --no-developer-cert with "mbed dm init" command

9800 Bare metal profile
Mbed OS may now be built without the RTOS by creating an mbed_app.json with the following contents:

{
"requires": ["bare-metal"]
}

9799 Increase events.share-eventsize to 768B because of ESP8266 AT driver and asynchronous DNS

"events.shared-eventsize" increased from 256B to 768B

Original value was too small once both the ESP8266 driver and asynchronous DNS started to use the shared event queue. An assumption is made that once the shared event queue is taken into use, there are going to be multiple users instead of one, for which the original value would have been sufficient.

9797 API to temporarily enable/disable FileHandles

• UARTSerial can now be temporarily or permanently disabled for input and/or output. This is particularly useful to save power when reception is not required - disabling input permits deep sleep. To do this more generically for the console, use mbed_file_handle(STDIN_FILENO)->enable_input(false).

9795 crypto: Update to Mbed Crypto 1.0.0d5 and then to 1.0.0d6
Previously, calls to psa_crypto_*_setup() would succeed even if a user did not initialize their operation context. Help users of the PSA Crypto API catch their own bugs by returning PSA_ERROR_BAD_STATE when a setup function is called with an uninitialized context.

9790 BLE conf
No changes made to existing programs. By default, all options are enabled, which is the current state.

9768 Bring USB Feature branch into master
This feature brings USB device support into Mbed OS from a feature branch. Targets that support USB include the LPC1768, ARCH_PRO, K64F, NUCLEO_F207ZG, NUCLEO_F412ZG, DISCO_F413ZH, NUCLEO_F413ZH, NUCLEO_F429ZI, NUCLEO_F446ZE, NUCLEO_F746ZG, NUCLEO_F756ZG, NUCLEO_F767ZI, DISCO_F469NI, DISCO_F746NG, DISCO_F769NI, DISCO_L475VG_IOT01A, DISCO_L476VG, RZ_A1H, GR_LYCHEE, DISCO_L496AG, NUCLEO_L496ZG, NUCLEO_L4R5ZI. Supported USB device classes include USBAudio, USBHID, USBMouse, USBKeyboard, USBMIDI, USBMSD, USBSerial and USBCDC.

9758 Allow hash or mac on large buffers with less memory use
Description: Hash and mac operations are now processed in secure partition in multiple chunks internally leading to decrease in memory use for large buffers.
Effect analysis: This change has no impact on API and should not alter behavior from the user perspective.
Migration: No action should be required from the user side.

9746 Cellular: Retire CellularBase class
In order to align to other connectivity technologies CellularBase is deprecated and CellularInterface usage is preferred. This change is backward compatible.

9708 Implement PSA protected storage & restructure PSA storage implementation

• Restructure PSA storage implementation (directory structure and common code)
• Add the PSA protected storage feature

9668 PSA Initial Attestation service

• A brief description of changes introduced.
  Add PSA Initial Attestation Service implementation.
• An analysis of effects: components affected, potential consequences for users and reasons for the addition or change.
  this code is a new feature and doesn't effect existing code.
• Migration guidance: actions for updating the current code. Please include code snippets to illustrate before and after the addition or change.
  This breaks backwards compatibility with Nucleo F411RE entropy injection.

9571 Update to 2-region model for HEAP and Stack Memory
RAM memory model is updated to a two-region model. RTOS and non-RTOS versions of Mbed OS across all targets and toolchains will have separate stack and heap sections. ISR stack size is unified across all targets and is set as 1K for Mbed OS with RTOS. In case of no RTOS, stack size is also the main thread size and is set as 4K.

9568 Merge feature cellular refactor
This PR has impact on cellular application development and porting of new cellular devices.

Application developers need to select the suitable NetworkInterface type. When using NetworkInterface NSAPI configuration defines are applied by default, see NSAPI configuration options for cellular in more details. CellularBase users have a new function set_default_parameters to apply NSAPI configuration options. CellularContext is to be used instead of CellularBase for new extended cellular functionality, such as NonIP sockets and EPS CP optimization...

Migration guidelines for application developers:

• Change CELLULAR_DEVICE macro to get_default_instance
• Change OnboardCellularInterface or EasyCellularConnection to CellularContext
• Call CellularDevice::set_data_carrier_detect to set HUP signal detection

Cellular API changes need to be taken into account when porting new cellular devices. This PR already contains the changes needed for the existing cellular drivers and the onboard modems. Arm has an internal ticket to update the cellular porting documentation for Mbed OS 5.12.

Migration guidelines for porting developers:

• Follow GENERIC_AT3GPP implementation when porting new AT based cellular devices
• Change power_on/off to onboard_modem_api with soft_power_on/off and hard_power_on/off
• Move implementation from CellularSIM and CellularPower to CellularInformation and CellularDevice
• Implement CellularDevice::init and CellularDevice::shutdown
• Use CellularNetwork::get_signal_quality instead of CellularNetwork::get_extended_signal_quality

9449 Pinmap extensions
Added pinmap support to the HAL API. For more information see the porting targets docs page - https://os.mbed.com/docs/mbed-os/latest/porting/porting-targets.html.

[9219](https://github.co...

We are pleased to announce the Mbed OS 5.11.5 release is now available.

Summary
