SDSoC Viterbi Decoder implementation

Hi everyone,

I have been trying to create "viterbi decoder C callable ip". What I am doing is that I am creating block design on VIVADO environment, create an HDL wrapper for it and then synthesize. Later I package the IP and create a static library .a file by using the outputting .xml file, a header file and Makefile. Since it is not possible to reach to what is included in .a file directly, I tried to generate .so file that reaches to that .a file. I was planning to call it by the client code such as main. Yet, I am seeing that datamover is being a problem. The error states that sideband TLAST signal is missing and it is needed by the SDSoC datamover. The viterbi IP doesn't include that signal and I have added it to HDL wrapper since it might work this way. Yet, I am observing another error and it is also about datamover which is actually I expected but i still tried. Is there a way out? Can't I make an IP C callable without sideband signals, TLAST/TKEEP?

 

Thank you for your time.
