Release mbed-os-6.0.0-beta-1 · ARMmbed/mbed-os

We are pleased to announce the Mbed OS 6.0.0-beta-1 release is now available.

Summary

This is the last pre-release before we make the full 6.0.0 release. It contains the remainder of the breaking changes and any other significant updates.

Migration Guide

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

Correct Timeout rescheduling

12941

Summary of changes

Chrono changes "optimised" Timeout::handler in a way that broke users who rescheduled the timeout during their attached callback.

Attempted optimisation is less necessary now that platform.callback-nontrivial is set to false by default - that setting reduces overhead of copying the Callback to almost nothing.

Fixes #12940.

Correct core RTOS sleep routine timing

12938

Summary of changes

Chrono conversions inadvertantly changed the core timed sleep routine used by the RTOS idle to use OsTimer::update_and_get_tick() instead of OsTimer::get_tick().

Correct this, and expand/clarify documentation and naming to try to prevent recurrence.

Another minor fix observed while inspecting code - OsClock can't just use milliseconds, it should match the period of OsTimer, which theoretically can be different.

Fixes #12920.

Remove unsupported targets

ARCH_PRO: Remove uARM tooolchain support

12853

Summary of changes

Update scatter file for the ARM toolchain to use 2 region memory model.
The scatter file changes affect the following boards:
LPC1768, ARCH_PRO, UBLOX_C027, XBED_LPC1768 (LPC1768.sct)
Remove the TOOLCHAIN_ARM_MICRO directory.
Remove release_version as not necessary and as the target can also run
Mbed OS 6.
Remove uARM toolchain in the list of supported toolchains for the target.
Indicate that the target supports the small ARM toolchain C library.

Impact of changes

It is no longer possible to use the uARM toolchain to build binaries for the ARCH_PRO board.

Migration actions required

Set the "target.c_lib" configuration option to "small" to build binaries using Microlib with the ARM toolchain.

Allow Devicekey::generate_root_of_trust() to define key size.

12823

Summary of changes

Allow Devicekey::generate_root_of_trust() to define key size.

By default, generate 16 byte keys, to be compatible with bootloader.
But allow user to generate 32 byte keys as well.

This fixes #12821

Impact of changes

Default key, generated by Devicekey::generate_root_of_trust() is now 16 bytes,
instead of 32 bytes.

Migration actions required

If you want to generate 32 byte keys with Devicekey::generate_root_of_trust(),
you need to explicitly supply key size as a parameter.

Remove deprecated Platform header files

12811

Summary of changes

Remove the deprecated header files as part of the Mbed 6 cleanup.

Impact of changes

Breaking change: Applications that include the removed files will no longer successfully build.

Migration actions required

Include the header files recommended in each removed header file:

platform/critical.h -> platform/mbed_critical.h
platform/mbed_sleep.h -> platform/platform/mbed_power_mgmt.h
platform/rtc_time.h -> platform/mbed_rtc_time.h
platform/semihost_api.h -> platform/mbed_semihost_api.h
platform/sleep.h -> platform/mbed_power_mgmt.h
platform/toolchain.h -> platform/mbed_toolchain.h
platform/wait_api.h -> platform/mbed_wait_api.h

Remove unsupported targets

12810

Summary of changes

This is the second of a series of PRs (first #12775) to remove targets that are not supported or retired as explained in recent blog post.

There are individual commits to remove targets from targets.json and files/folders for the corresponding targets.

Impact of changes

The following targets are being removed:

MTBs (most)

LittleFSv2: Bring in v2.2

12783

Summary of changes

Introduces LittleFSv2.2 developed by @geky. Mbed OS adaption (LittleFSv1 -> LittleFSv2) is based on work done by @pilotak. The only thing the undersigned has done was to create this PR.

Impact of changes

None

Migration actions required

Brings in LittleFSv2 which will coexist with LittleFSv1 already found from Mbed OS. If you already a v1 filesystem you might try converting it to v2, but this isn't guaranteed to succeed. You should preferably create a new v2 filesystem instead.

Callback: Trivial default

12761

Summary of changes

Turn off callback.non-trivial by default to save ROM space.

Follow-up to #12036. Will need at least one example changed to turn the option back on.

Impact of changes

If application code uses Callback with a non-trivial functor, they will get a compilation error directing them to turn on platform.callback-nontrivial.

Migration actions required

Add "platform.callback-nontrivial": true to your mbed_app.json if a build error indicates that it is required - or change your code to only use trivial functors in Callback.

BLE: remove deprecated APIs from Gatt and SecurityManager

12742

Summary of changes

Remove deprecated APIs from Gatt
Remove deprecated APIs from SecurityManager

Impact of changes

Deprecated APIs from Gatt and SecurityManager do not exist anymore, applications that use them will not compile until updated with current APIs.

Migration actions required

Applications that compile without deprecation warnings on mbed-os-5.15 will continue to work. Otherwise, please fix any deprecated API usages, for example by referring to compilation warnings from mbed-os-5.15.

Add Semtech Lora radio drivers

12741

Summary of changes

Add Semtech Lora radio drivers for SX1272, SX1276 and SX126x radios.
Added as subtree from original repository: https://github.com/ARMmbed/mbed-semtech-lora-rf-drivers

Impact of changes

Enable using Lora with no additional repositories, all of them part of Mbed OS.

Migration actions required

None

Remove Mbed SPM

12738

Summary of changes

Remove FUTURE_SEQUANA and FUTURE_SEQUANA_M0 targets. These are not supported in Mbed 6.

After the removal of FUTURE_SEQUANA targets, there are no targets remaining that use Mbed SPM. Remove Mbed SPM as well, as it is unused.

Impact of changes

The following targets are being removed in Mbed 6:

FUTURE_SEQUANA
FUTURE_SEQUANA_M0

Migration actions required

Please use a version of Mbed OS 5 if you require support for FUTURE_SEQUANA or FUTURE_SEQUANA_M0

Remove PSA implementation for v8-M and dual CPU targets

12737

Summary of changes

With Mbed 6, TrustedFirmware-M (TF-M) is the source of Mbed's implementation of PSA. This means Mbed 6 doesn't need to contain any code or tooling to build the v8-M or dual CPU secure binaries.

This patch set removes tooling, code, and targets that would have been used to make PSA secure binaries for v8-M or dual CPU platforms.

Impact of changes

NXP LPC55S69 and Numaker M2351 support is temporarily dropped as compared to Mbed 5, as those targets are not supported in TF-M upstream.
Exporters for v8-M and dual CPU PSA targets are not supported, due to TF-M limitations.
It is no longer possible to use Mbed to build v8-M or dual CPU secure binaries.
The following targets are removed compared to Mbed 5:
ARM_MUSCA_A1_S
ARM_MUSCA_B1_S
LPC55S69_NS
LPC55S69_S
HANI_IOT
NU_PFM_M2351_NS
NU_PFM_M2351_S

Migration actions required

Use Mbed 5.15 if you require PSA targets with exporter support, or one of the removed targets. LPC55S69 and Numaker M2351 will be supported in Mbed 6 at a later date, after the targets are supported by TF-M.

rtos: Improve CMSIS-RTOSv2 app compatibility

12736

Summary of changes

Some non-Mbed-OS, pre-existing CMSIS-RTOSv2 applications depend on
CMSIS-RTOSv2 Automatic Dynamic Allocation, also known as Object-specific
memory pools. Mbed OS doesn't by default provide any memory to the
CMSIS-RTOSv2 Automatic Dynamic Allocation pool, as doing so would waste
memory if the feature is not used; even if the feature is used, as a
platform, Mbed OS can't know how many objects of which types will be
created by an application and therefore will either waste memory or not
provide enough memory in a hard to debug manner. Portable CMSIS-RTOSv2
applications depending on CMSIS-RTOSv2 Automatic Dynamic Allocation
should instead configure the memory pools themselves, as applications
know best their memory requirements.

Add Mbed configuration options which can be used by applications to
control the amounts of memory available to the CMSIS-RTOSv2 Automatic
Dynamic Allocation subsystem. This enables portable CMSIS-RTOSv2
applications, which can run on any CMSIS-RTOSv2 OS, to be able to run on
Mbed OS as well.

Signed-off-by: Devaraj Ranganna [email protected]
Signed-off-by: Jaeden Amero [email protected]

Impact of changes

Applications written for CMSIS-RTOSv2 that use CMSIS-RTOSv2 Automatic Dynamic Allocation can now also run on Mbed OS, when the application specifies how much memory to use in their mbed_app.json. CMSIS-RTOSv2 docs claim that Automatic Dynamic Allocation is "fully portable", and now that's at least more true than before where Mbed is concerned.

The TF-M regression tests are a concrete example of an application written making use of CMSIS-RTOSv2 Automatic Dynamic Allocation. We have an incredibly easier time running (and maintaining) those tests with Mbed OS, validating the TF-M integration with Mbed OS does not break TF-M functionality, when Mbed OS supports application-configured CMSIS-RTOSv2 Automatic Dynamic Allocation.

Migration actions required

None

odin targets: remove release version

12733

Summary of changes

This is a preparation for more upcoming changes. The latest master updates removed deprecated functionality and these targets do not compile anymore.

Impact of changes

Boards based on the ODIN module won't compile in Mbed OS 6.0.0.

Migration actions required

Staying with Mbed OS version up to 5.15.x.

BLE Gap deprecation cleanup/rework

12730

Summary of changes

Remove BLE LegacyGap class and implementations. Map ble::Gap to global Gap.
Add non-deprecated APIs (originally found in LegacyGap) to Gap and implementations into GenericGap.
Remove/replace legacy BLE event signalling (callback chains) in favour of EventHandler, where possible.
Remove BLEProtocol:: and replace AddressType_t with own_address_type_t/peer_address_type_t, AddressByte_t with address_t, etc.
Replace BLE::Address_t (for accessing address types + values in whitelists) with the new equivalent whitelist_t::entry_t.
Rename ConnectionParams_t -> PreferredConnectionParams_t and use it only for Generic Access Service.
Fix misspelt central_privay_configuration_t -> central_privacy_configuration_t
Remove legacy type definitions and replace internal usages with new types, e.g. address types, disconnection reason, etc.

Notes:

setDeviceName(), getDeviceName(), setAppearance(), getAppearance() from LegacyGap are removed, as device name and appearance can be set via AdvertisingDataBuilder and saved by the application. But there were previously no deprecation warnings for them.
get/setPreferredConnectionParams() are dropped from Gap - updated versions will be added to Gatt where they should belong to.

Impact of changes

Legacy BLE Gap APIs and related type definitions are no longer available.
Some APIs have been updated to take parameters of new type definitions of address types + values.

Migration actions required

Applications based on up-to-date BLE APIs should be able to make most BLE function calls as before.
However as mentioned above some deprecated types (e.g. address) were not warned previously - their usages need to be replaced with corresponding new types. The best clue is compilation errors which can be manually fixed. The PR to update mbed-os-example-ble is an example of how to do this: ARMmbed/mbed-os-example-ble#289
Applications should set device name and appearance using AdvertisingDataBuilder and internally remember their values as needed, since APIs to get/set them are removed as explained above.

RZ_A1H remove usage of ethernet hal API

12715

Summary of changes

Removed ethernet_api from targets\TARGET_RENESAS\TARGET_RZ_A1XX.
Modified features\netsocket\emac-drivers\TARGET_RZ_A1_EMAC not to use ethernet_api.

targets:MIMXRT1050: Add QSPI flash support

12711

Summary of changes

targets:MIMXRT1050:

QSPI Flash boot support
QSPI Flash FLASHIAP support
Update link file for application and bootloader

Summary of changes

Original work: #12468 . This PR contains also the UT fix.

Add optimised constexpr default constructor. Default construction was previously by a heavyweight defaulted nsapi_addr_t parameter.
Remove deprecated resolving constructor.
Take nsapi_addr_t inputs by constant reference rather than value.
Inline the trivial getters and setters.
Use unique_ptr to manage the text buffer.
Make operator bool explicit.
Optimise some methods.
Update to C++11 style (default initialisers, nullptr etc)

Impact of changes

Constructor deprecated in Mbed OS 5.1 removed.
Code size reductions, particularly on default initialisation.
Implicit assignments to bool or int or others no longer possible - any existing code which does not compile is most likely an error. (if (sockaddr) is still fine - such "contextual conversions to bool" can use the explicit operator).

Migration actions required

Code attempting resolution by passing a hostname to SocketAddress's constructor must be modified to use NetworkInterface::gethostbyname or NetworkStack::gethostbyname.
Code failing due to the now-explicit bool operator should be reviewed to check intent.

Remove deprecated BLE:: APIs and unsupported services

12676

Summary of changes

Remove deprecated APIs from BLE namespace.
Remove DFUService, UARTService and beacon-related services (iBeacon, EddyStone) whose standards/stacks are externally maintained.

Impact of changes

Legacy APIs in BLE namespace are no longer available.
DFUService, UARTService and beacon-related services (iBeacon, EddyStone) are no longer available.

Migration actions required

Applications that use legacy APIs in BLE namespace need to be updated to use up-to-date APIs.
Applications based on removed services can copy the service definitions over from previous mbed-os releases (with deprecated API usages manually fixed), or provide their own implementations.

Remove Maxim and SoftDevice BLE stacks which do not support the latest APIs

12674

Summary of changes

Remove Nordic SoftDevice stack (used by nRF51* targets). Notes: nRF52* targets are unaffected as they use Cordio stack.
Remove the current Maxim BLE stack (until a newer version based on up-to-date Cordio stack becomes available).
Disable BLE features of affected targets from targets.json.

Note: Some references/macros for SoftDevice are still present in the Nordic SDK (targets/TARGET_NORDIC/*) and not cleanly separated with other components.

Impact of changes

BLE feature will be unavailable on nRF51* targets and temporarily unavailable on Maxim targets until the driver gets updated in the future.

Migration actions required

For nRF51* targets, use Mbed OS release 5.15 - future support for those targets are under review.
For nRF52* targets, ensure the default BLE configurations that enable Cordio stack is used.
For Maxim targets, use Mbed OS release 5.15 until the BLE driver gets updated.

Netsocket: Introduce set_ip_address and get_dns_server APIs

12606

Summary of changes

set_ip_address API can be used to set a static IPv4 address or IPv6 link-local address to network stack. This is needed for example in cellular use cases where device gets multiple IP addresses from cellular context.

With get_dns_server DNS servers can be queried from NetworkInterface object

Fully enforce NonCopyable

12581

Summary of changes

Summary of changes

Add new API to network interface.

Property API allows application to ask network specific properties
from the InternetSocket . Queried information can be used to avoid
network congestion by adjusting transmission jitter and retry
timeouts.

C++ Chrono support

12425

Summary of changes

Add Chronos versions of time-related APIs to RTOS classes, Ticker-related classes and EventQueue.

Kernel::Clock, HighResClock, LowPowerClock and RealTimeClock act as the Chrono clocks. (C++ standard clocks system_clock, steady_clock and high_resolution_clock are not supported, due to difficulty in consistent retargetting across toolchains).

Deprecate old non-Chrono APIs.

Impact of changes

Existing timing code will generate deprecation warnings, but there should be no functional change.

A follow-up PR will clean-up warnings in rest of code base.

Migration actions required

Users should migrate to use Chrono-based APIs as directed by the deprecation messages

Remove the deprecated RawSerial, UARTSerial, Serial

12410

Summary of changes

Removed RawSerial, Serial, UARTSerial deprecated classes.
Removed SerialBase deprecated APIs.

Impact of changes

Breaking change: RawSerial, Serial, UARTSerial classes have been deprecated since Mbed OS 6.0.0 and they are all removed now.

Migration actions required

Use BufferedSerial and UnbufferedSerial for serial communication.

Add get_time function to ESP8266

12300

Summary of changes

Fixes #12192.

get_time() function allows access to (S)NTP functionalities of ESP8266 module.

I considered using std::chrono instead of ctime's std::tm, but then - to convert to chrono::time_point we'd have to go through std::tm anyway or write our own parser, which I just managed to avoid.

Side note: using std:: introduces some warnings due to -D_LIBCPP_EXTERN_TEMPLATE(...)= flag being used in all our compilation profiles. This flag seems obsolete and I hope I will get it removed soon.

I cannot really add any tests, as they are using WifiInterface::get_instance() to get the interface and there is no RTTI, that would allow casting to ESP8266Interface to call get_time(), but I tested the function locally and it works fine.

Impact of changes

None, other than user can check time with ESP8266Interface.

Migration actions required

None

Make cypress psoc64 TFM ready and also add TF-M initialization

12271

Summary of changes

Non-secure core IPC, Mailbox and Interface init for TFM_DUALCPU and TFM_V8M targets

These changes concentrate on getting mbed-os(Non-secure) working with TF-M(secure)
Changes reflect towards any Cypress based TFM_DUALCPU targets and TFM_V8M targets at the moment and making it more generic in the near future.

Key changes:

Init IPC, Mailbox and Non-secure Interface.
These changes are for TFM_DUALCPU and TFM_V8M platforms.
The initialization happens after mbed-os kernel is kicked off and
when the thread is up and running.

We are initializing the following for TFM_DUALCPU platforms:

IPC Interrupts for syncing multi-core platforms.
NS Mailbox to receive messages.
NS interface.

We are only initializing a Non-secure interface for TFM_V8M platforms.

Cypress: CY8CKIT_064S2_4343W: Reserve timer channels used by TF-M.
Make CY8CKIT_064S2_4343W Cypress target TF-M compatible.

Impact of changes

This impacts CY8CKIT_064S2_4343W, TFM_V8M and TFM_DUALCPU targets.

Migration actions required

None

Callback extension and optimisation

12036

Summary of changes

Extend Callback, and optimise it.

Impact of changes

Optimise clearing by adding nullptr overload.
Optimise clearing by not clearing storage - increases code size of comparison, but that is extremely rare.
Reduce ROM used by trivial functors - share copy/destroy code.
Config option to force trivial functors - major ROM saving by eliminating the "operations" table.
Config option to eliminate comparison altogether - minor ROM saving by eliminating zero padding.
Conform more to std::function API.

Migration actions required

The added nullptr overload means Callback(NULL) or Callback(0) will no longer work; users must use Callback(nullptr) or Callback().

Known Issues

There are no new known issues with this release.
