Suggested Steps:

1. First, update to the latest repository code.
2. Confirm the OpenOCD command works and enters the polling phase:
   openocd.exe -f ch347.cfg -f xilinx-xc7.cfg -f jtagspi.cfg
3. The programming procedure is as follows:

   init
   pld load 0 bscan_spi_xc7a35t.bit
   reset halt
   flash probe 0
   flash erase_sector 0 0 last
   flash write_image test.bin 0x0 bin
   

   (Note: The bscan_spi_xc7a35t.bit file is from the https://github.com/quartiq/bscan_spi_bitstreams.)

Simpler Alternative: If this process seems too complex, consider trying the openFPGALoader project instead.
