Known issues
============

Some open issues are not fixed in this release.

.. list-table::

  * - **Descriptions**
    - **Issue links**

  * - | PSA Arch Crypto test suite have several known failures.
    - See this `link <https://developer.trustedfirmware.org/w/tf_m/release/psa_arch_crypto_test_failure_analysis_in_tf-m_v1.5_release/>`_
      for detailed analysis of the failures.

  * - | Armclang 6.17 generates STRBT instead of STRB in privileged code.
      | MemManage fault occurs when the privileged code calls STRBT to access
      | a memory location only for privileged access.
      | The root cause is still under analysis by Armclang. Please use other
      | Armclang versions instead.
