Known Issues

  • IAR Compiler 8.20.1 does not support access to PSPLIM and MPSLIM on ARMv8-M Baseline (Cortex-M23) using compiler intrinsics. You might get an error like:

    __set_PSPLIM((uint32_t)ProcessStackMemory);
    ^
    ".\tz_context.c",74 Error[Ta140]:
    Special register "PSPLIM" is not available

    Work around: Remove setting PSPLIM until a fixed compiler version is available.
