+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.
