Hi wolfgang,I think it cannot solve my issue since I can detect another FPGA using my desktop and blaster. I think it is related to my wrong write to FPGA using JTAG chain debugger. Really need your help.

I have saw these two videos but it cannot solve my issue, the two videos only give an example to communicate with a good device but do not tell me how to confirm if my device is broken and how to fix it such as write some value to some registers.
