We are pleased to announce the Mbed OS 6.15.0 release is now available.

Summary

The main focus with this release is bringing our support up to date for both the GCC and Arm compilers, so GCC10 and Arm 6.15.0 respectively, and now supporting TF-M v1.4. With this, Mbed OS can now support v8.1-M of the Arm Architecture and will support upcoming M55-based MCUs from the Arm ecosystem.

need special attention.

New feature: send/recv message implementation added to network stack

15040

Summary of changes

This PR is continuation of another stale PR: #14847. I am opening this one, as I didn't have access to push to the fork created by other developer.
I have added few changes related to unresolved comments:

  • function names were changed from socket_sendmsg/socket_recvmsg to socket_sendto_control/socket_recvfrom_control.
  • default implementation of this functions was provided in the NetworkStack class to not break the existing API. This was the issue that caused tests to fail in the previous PR.
  • MsgHeaderIterator accesses elements on the aligned addresses
    .

SFDP: Add support for multiple configurations and sector maps

14989

Summary of changes

Fixes #12574
This PR adds to following changes, to support CYW9P62S1_43012EVB_01's QSPI flash (S25FS512S):

  • A Sector Map Parameter Table contains a sequence of the following descriptors:
  • (Optional) configuration detection command descriptors, one for each command to run to determine the current configuration. This exists only if the flash layout is configurable.
  • Sector map descriptors, one map for each possible configuration. On a flash device with a non-configurable layout, there is only one such descriptor/map.
    Previously we only supported the non-configurable case with a single descriptor. This PR adds support for multiple configurations and provides a positive unit test case.
  • To be able to run configuration detection commands, a callback provided by each block device and used by the SFDP class needs to take additional parameters: address size, instruction and dummy cycles. Their values come from sector map descriptors in the SFDP table. This PR changes the callback interface, and updates callbacks implemented by SPI, QSPI and OSPI block devices to the extended interface.
  • A quirk is provided for Cypress S25FS512S flash device's inconsistent register value: This device's SFDP table suggests checking CR3NV[1], which needs to be 1 in order for the config detection algorithm to work. But the actual hardware has value 0 instead. This has been discussed before on the Internet (e.g. on a Linux mailing list) - it's not possible to change a value in hardware that has been in production for years.
  • Two of the three configurations of S25FS512S have eight 4KB sectors (32KB in total) overlaying a 256KB sector. This type of partial overlay is not current supported by Mbed OS's BlockDevice and SFDP parser. A quirk is provided to ignore the 4KB sectors and only use the 256KB sectors.
  • Fixes of a few preexisting issues we found.
