Known Issues or Limitations

Corstone-1000

There is a performance issue with RSA key generation - RSA key generation is slower than expected. This is a known platform issue.
Due to limited performance, characters may be dropped if too much data is sent too quickly. Consider inserting delays between characters if sending files or large buffers.
Due to the limited performance, K3s is not currently supported.

Corstone-1000 FVP

RsaPkcs1v15Crypt operations do not work properly due to the limited support in crypto-cell drivers

N1SDP

Support for the N1SDP platform in Cassini is primarily intended for development, test, and demonstration of features for infrastructure platforms which typically use EDK2 and Trusted Services without a secure enclave.
Due to a limitation of the platform hardware (it does not have enough Secure world RAM) Trusted Services is configured to run from Normal world RAM. This configuration is not compliant with the PSA specifications. Platforms intended for production should be configured by the platform provider to be compliant with the PSA specifications.
Booting the distribution image from USB storage device means storage performance may be may limited by that device. If unexpected issues or test failures are seen when booting from USB, try using a USB device with better performance or alternatively try booting from a SATA storage device.

RCU stalls may be detected during boot or in some test cases

Known Test Failures

All platforms

The following tests are expected to fail:
- AWS Greengrass IoT Device Tester
  - GGV2Q cloudcomponent and mqttpubsub fail a SignatureException on the device under test
  - GGV2Q lambdadeployment randomly fails to deploy the test component

Corstone-1000

The following tests are expected to fail:
