PKHA is present on mx6ul and not present on mx6q. mx6uq uses the generic rsa driver and handles the certificate correctly. mx6ul uses pkcs1pad(rsa-caam,sha256) and it fails to handle the certificate. So that explains the different behavior of mx6q versus mx6ul. Any ideas as to how to fix rsa-caam? Thanks
