In Linux system, by the BMC , use altera-stapl driver to configure CPLD max2 with JBC file through JTAG interface, the result is given back as: Unrecognized device. How to solve this problem?

[KLing4]

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.

• The driver code that prints the error message

• Print out the opcode and parameter information for each execution

• The driver prints the following information

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

The jtag connection is ok , I'm sure.

Can you show your screenshot of your jtagconfig first?

Thanks

[KLing4]

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.

Hi KLing4,

Did the 'jtagconfig' in LINUX is successful?

And one more thing, did you change the permissions on the the device files? If not, you can try this step:

I hope this will help you.
