# BSCAN proxy bitstreams
Pre-built "BSCAN proxy" bitstreams that bridge the JTAG `USER1`
instruction to an FPGA's SPI flash pins (via a `BSCANE2` primitive),
enabling fast SPI flashing — see `doc/tutorial.md`, Phase 2.5.
These `.bit` files are **not** built here. They come from
[quartiq/bscan_spi_bitstreams](https://github.com/quartiq/bscan_spi_bitstreams),
© QUARTIQ GmbH, MIT-licensed — see `LICENSE.quartiq`. The host-side
framing in `modules/bscan_spi/` matches OpenOCD's `jtagspi` so the same
bitstreams work.
| File | Part | Used by |
|------|------|---------|
| `bscan_spi_xcku040.bit` | Xilinx Kintex UltraScale XCKU040 | KCU105 |
To add another part, drop the matching `bscan_spi_<part>.bit` here and
point the registry entry's `proxy_bitstream` field at it.
