Boundary scan is not implemented on 176x/175x, therefore, there is no BSDL file available.
To check the MCU pin connection of the board, it is recommended that the user create their own software, to read the input pins, and to write HIGH / LOW to the output pins. Then the data can be dumped into serial port (or any available output peripheral or stored in the internal SRAM then read by JTAG).
