Known issues

Some open issues are not fixed in this release.


Issue links

PSA Arch Crypto test suite have several known failures.

See this link 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.

Issues closed since v1.4.0

The following issues in v1.4.0 known issues list are closed. These issues are related to platform hardware limitations or deprecated platforms and therefore won’t be fixed by TF-M.
