Rewrite the Phase 2.5 tutorial section for the now-working path: fetch
the proxy bitstream, bscan_load_bitstream, bscan_jedec, and the
bscan_spi_xfer primitive. Note the JPROGRAM reconfiguration caveat. The
shown JEDEC output is illustrative — not yet hardware-confirmed.
Drop the get_/set_/_pin/_list noise from the JTAG commands (e.g.
jtag_get_probes_list -> jtag_probes, jtag_set_spi_cs_pin -> jtag_spi_cs,
jtag_spi_rd_wr -> jtag_spi_xfer). jtag_open_probe -> jtag_open (not
jtag_probe, which would clash with jtag_probes under tab-completion).
Hard rename, no aliases. Updates the state-dump emitter, help text,
example script and docs accordingly.
CLAUDE.md/README/tutorial: optional BS_ENABLE_DIGILENT backend, why
SMT2 modules need libdjtg, and the new jtag_open_probe index. Mark
phases 2 and 2.5 done.
doc/tutorial.md walks from probe detection to JEDEC ID over EXTEST and
forward-references the BSCAN proxy path. Includes:
- prerequisites and build/launch
- chain scan, FPGA identification, registry lookup
- IR/DR primitive sanity check via the IDCODE register
- SPI JEDEC ID over EXTEST (with the speed caveat)
- recipe to add a new FPGA target
- troubleshooting cheat sheet
README and CLAUDE.md updated to point at it.
