    Hi,

    Intel Arria 10 PAC card is working properly,the drivers got installed and able to run applications on them in x86 based server systems,But facing issues while trying to do the same with RISC-V CPU

    Is it possible to program Intel PAC card through RISC-V CPU using JTAG.RISC-V CPU(SoC) based Hifive Sifive Unmatched Board has a support for JTAG.What are the steps that are to be implemeted to program Intel PAC card through JTAG.Kindly mention.

    Thanks&Regards
