mbed-os-6.14.0

We are pleased to announce the Mbed OS 6.14.0 release is now available.

Summary

The main changes provided by this release are upgrades of the Fat Filesystem to version R0.14b and CMSIS to 5.8.0, both bringing improved stability and reliability. We've also added a SPI NAND block device driver for using SPI NAND Flash, like Macronix Flash MX31LF4GE4BC.

Migration Guide

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

FatFs: upgrade to R0.14b

14911

Summary of changes

Current upstream version of FatFs was now R0.14b with a lot of fixed since R0.13a. LINK
So we migrated Mbed-OS modification in R0.13a back to R0.14b and change some that affect in FATFileSystem.cpp

Impact of changes

FatFs version upgrade that may introduce new regression from upstream.

Migration actions required

FatFs has been upgraded to R0.14b. This comes with the following API changes requiring migration for direct users of FatFs. Users of the Mbed OS C++ class FATFileSystem do not need to change their use of FATFileSystem.
f_mkfs() now takes a MKFS_PARAM *opt instead of a BYTE opt and DWORD au.
f_fdisk() now takes an LBA_t ptbl[] instead of a DWORD *szt.

CMake: tests: Support skipping unsupported test with reason

14902

Summary of changes

Fixes #14856
Add a new argument TEST_SKIPPED to mbed_greentea_add_test() to indicate a test is skipped and give a reason (e.g. the Mbed target and/or configuration does not provide what the test requires).
The skip reason of a test is printed when running tests with ctest, and the test is marked as "Skipped" in the test report.
As a showcase, use this mechanism to skip the PSA Attestation test if baremetal is used or PSA and Experimental API are unavailable. Also update the ticker test (whose CTest support was added in #14892) to skip if microsecond ticker is unavailable.

Update CMSIS to 5.8.0

14900

Summary of changes

Update CMSIS to 5.8.0. It brings lot of fixes, see https://github.com/ARM-software/CMSIS_5/releases/tag/5.8.0
We again had some breakages, mainly it was arm compat (workaround implemented).

Dont require icetea

14880

Summary of changes

Remove icetea requirement.

Impact of changes

icetea is no longer listed as a default dependency.

Migration actions required

If you require icetea, you must install it separately as it is no longer listed as a default dependency of mbed-os in requirements.txt.

Add config macros for device-variant, freq-support and xtal config

14730

Summary of changes

Fixes #14726 by adding config macros for device-variant, freq-support and xtal config.
Settings these macros to -1, the selection pins are used.

add SPI NAND Block device driver

14397

Summary of changes

Add SPI NAND block device driver for using SPI NAND Flash like Macronix Flash MX31LF4GE4BC.

Known Issues

There are no new known issues with this release.
