In addition, the altera-stapl driver comes from the Linux kernel and is downloaded from kernel.org , the asp-cpld is the JTAG code of the adaptive BMC.

    Hi KLing4 ,

    Can you check your JTAG connection first whether it is working or not? (jtagconfig)

    open Command Prompt/Terminal ---> go to Quartus directory <Quartus installation directory>intelFPGA\18.1\quartus\bin64> ---> run jtagconfig

    Cheers

        Sorry , I haven't .The answer by the custome . And they can use the Quartus-programmer to configure the device through the Jtag interface sucessfully.
