I am running wolfSSL baremetal on a Xilinx Ultrascale+ SoC. It is documented that wolfSSL supports the Xilinx hardware crypto, however it appears it has not been updated since Xilink SDK 2017. I have tried port it to the latest SDK myself and both SHA3 and AES work however RSA does not. I keep getting the following error on the client side.

RsaUnPad error, invalid formatting
wolfSSL Leaving ConfirmSignature, return -155

If I run the woflSSL tests they also fail with error -6773. I am running wolfSSL 4.3.0.
