Hello,

 

Could you share:

1. The exact device at @1 (family & part number)?
2. The BSDL snippets for INSTRUCTION_OPCODE (SAMPLE/EXTEST/BYPASS/IDCODE) and BOUNDARY_LENGTH.
3. Whether there are other devices in the chain (what does get_device_names / jtagconfig show)?

    Please find the response as below:

    1. It is a customized JTAG board.
    2. 0x00000000 is the EXTEST code and the boundary length is 48bits
    3. No, It is the only device connected (soo far) in the chain.

      Sorry, as I do not quite understand what you mean on the customized JTAG board. What FPGA device are you using in this case?
