Known Issues or Limitations
---------------------------
 - The external-system can not be reset individually on (or using) AN550_v1 FPGA release. However, the system-wide reset still applies to the external-system.
 - FPGA supports Linux distro install and boot through installer. However, FVP only supports openSUSE raw image installation and boot.
 - Due to the performance uplimit of MPS3 FPGA and FVP, some Linux distros like Fedora Rawhide can not boot on Corstone-1000 (i.e. user may experience timeouts or boot hang).
 - Below SCT FAILURE is a known issues in the FVP:
   UEFI Compliant - Boot from network protocols must be implemented -- FAILURE
 - Below SCT FAILURE is a known issue when a terminal emulator (in the system where the user connects to serial ports) does not support 80x25 or 80x50 mode:
   EFI_SIMPLE_TEXT_OUT_PROTOCOL.SetMode - SetMode() with valid mode -- FAILURE
 - Known limitations regarding ACS tests: The behavior after running ACS tests on FVP is not consistent.  Both behaviors are expected and are valid;
   The system might boot till the Linux prompt. Or, the system might wait after finishing the ACS tests.
   In both cases, the system executes the entire test suite and writes the results as stated in the user guide.

Known Issues or Limitations
---------------------------

 - Before running each SystemReady-IR tests: ACS tests (SCT, FWTS, BSA), manual
   capsule update test, Linux distro install and boot, etc., the SecureEnclave
   flash must be cleaned. See user-guide "Clean Secure Flash Before Testing"
   section.

Known Issues or Limitations
---------------------------
 - The following tests only work on Corstone-1000 FPGA: ACS tests (SCT, FWTS,
   BSA), manual capsule update test, Linux distro install and boot, and
   psa-arch-tests.
 - Only the manual capsule update from UEFI shell is supported on FPGA.
 - Due to flash size limitation and to support A/B banks,the wic image provided
   by the user should be smaller than 15MB.
 - The failures in PSA Arch Crypto Test are known limitations with crypto
   library. It requires further investigation. The user can refer to `PSA Arch Crypto Test Failure Analysis In TF-M V1.5 Release <https://developer.trustedfirmware.org/w/tf_m/release/psa_arch_crypto_test_failure_analysis_in_tf-m_v1.5_release/>`__
   for the reason for each failing test.
