Test vector for PKSC1V2.2 RSASSA-PSS signature scheme

I'm working on PKSC1V2.2 RSASSA-PSS Signature Scheme. I got some standard test vector for the final results testing, but my results are not matching. To check where my code is going wrong, I need some test vector with intermediate result.

and I'm using RSA 2048 and SHA 256.

please help ... if anyone has it or if you know where can I get it? also any other method to test it.

Regards
