BlueSCSI/BlueSCSI-v2 v2026.04.27

on GitHub

This release brings a new build system, a much simpler firmware update flow, broader SCSI command coverage, and a long list of fixes across CD-ROM, CD audio, tape, DaynaPORT, initiator mode, and the Ultra/Ultra Wide hardware.

New Features

Firmware update & logging

• Universal firmware ZIP — firmware_update() scans the SD card root for BlueSCSI_v*.zip, extracts the target-specific .bin, and hands it to the bootloader. Same ZIP works for every board. (cb61c37 — @erichelgeson)
• Shared bootloader log — a 2 KB NOLOAD region at the top of RAM survives the reset from bootloader into main firmware, so firmware-update log lines are no longer lost. (cb61c37 — @erichelgeson)
• lastlog.txt — previous session's log.txt is renamed to lastlog.txt on first boot before the new log starts, so the prior run is always recoverable. (cb61c37 — @erichelgeson)

BlueSCSI Toolbox

• SET_WORKING_DIR (subcommand 0x02) — Toolbox clients can point file operations at the SD card root (or any directory) for firmware uploads and file management. (24bbc20 — @erichelgeson)
• GET_WORKING_DIR (subcommand 0x03) — returns the currently effective directory as a null-terminated string so clients can display it. (25fdaa6 — @erichelgeson)
• New capability flag CAP_SET_WORKING_DIR (bit 2, 0x04) lets clients detect support. (24bbc20, 25fdaa6 — @erichelgeson)

SCSI commands

• READ(12)/WRITE(12), READ(16)/WRITE(16), READ CAPACITY(16) — proper dispatch for the 12- and 16-byte disk commands. (c4f8a73 — @reinauer)
• VERIFY(10/12/16) — medium scan (BYTCHK=0) and byte-compare (BYTCHK=1) both implemented. (c4f8a73 — @reinauer)
• WRITE AND VERIFY(10/12/16) — data is written and re-read to confirm the sectors match. (c4f8a73 — @reinauer)
• MODE SENSE Verify Error Recovery page (07h) — optional SCSI-2 §9.3.3.8 page 07h (page length 0Ah, verify retry count 1, other fields zero), returned only in SCSI-2 mode. Some vintage OSes expect this page when requesting all pages (0x3F). (318a1c1 — @erichelgeson)
• MODE SENSE Notch and Partition page (0Ch) — optional SCSI-2 §9.3.3.5 page 0Ch with all fields zero, indicating a non-notched drive. Returned only for SCSI-2 direct-access devices (excluded from optical and sequential). (1e1a1a5 — @erichelgeson)
• Trace log coverage for new commands — SCSI trace output shows names for Read16, Write16, Verify16, WriteVerify16, ServiceActionIn16, Write12, Verify12, WriteVerify12. (8bcc3c8 — @PetteriAimonen)

Initiator mode

• Fixed VHD image output — with InitiatorVHD=1 in bluescsi.ini, imaged drives are saved as Microsoft Fixed VHD files with a conforming 512-byte footer, directly mountable in Windows/QEMU/VirtualBox. (e7ebcab — @erichelgeson)
• Wide bus scans SCSI IDs 8-15 — on wide builds, initiator mode scans all 16 IDs. Imaged filenames encode the target ID as a single character: 0-9 for IDs 0-9, A-F for 10-15 (e.g. a drive at ID 11 becomes HDB0_imaged.hda). (7d17253 — @morio)
• Skip non-block SCSI peripheral types — only block-style peripherals (direct-access, optical, CD-ROM, etc.) are cloned now; printers, scanners, processors and other non-block targets are skipped, and the full peripheral type name is logged. (5d19165 — @morio)

Diagnostics

• Hardware stack overflow protection (RP2350) — MSPLIM is set on both cores with 32 bytes of exception-frame headroom; overflows now crash-dump instead of corrupting RAM. (20823c9 — @erichelgeson)
• Enhanced hardfault logging — CFSR/HFSR/MMFAR/BFAR are decoded into human-readable fault conditions on RP2350. (20823c9 — @erichelgeson)
• SD card OID decoded in log — the card identification line now prints the 2-byte OID as ASCII alongside the resolved manufacturer name, making it easier to identify the exact card in a user's log. (ad1494a — @erichelgeson)
• SCSI trace shows opcode hex — COMMAND: log lines now print the opcode byte alongside the decoded name, e.g. ---- COMMAND: 0x12 (Inquiry) and ---- COMMAND: 0xDE (Unknown), so unknown opcodes are immediately actionable instead of requiring you to correlate with the next OUT hex dump. (c785237 — @p0dalirius)
• Debug log mask covers wide IDs 8-15 — g_scsi_log_mask is now uint32_t and defaults to all bits for S2S_MAX_TARGETS, so per-ID debug logging works on wide builds with IDs 8-15. (5ab53a0 — @morio)

Bug Fixes

CD-ROM & CD audio

• SPDIF crash on multi-BIN CUE sheets (#353) — selectImageFile() no longer allocates FastSeek for metadata-only opens, and doReadTOC / doReadFullTOC / doReadTrackInformation stop audio before switching BIN files. (8b06063 — @erichelgeson)
• SPDIF reported wrong LBA on READ SUB-CHANNEL / PLAY AUDIO (#353) — the audio position math now accounts for each track's file_offset and data_start, so multi-BIN CUEs and tracks with unstored PREGAP report correct LBAs. (a2835e6 — @erichelgeson)
• SPDIF PLAY AUDIO seek wrong for tracks with PREGAP — doPlayAudio now uses data_start instead of track_start, fixing audio on discs like Tatsujin Ou (FM Towns) where Track 2 has PREGAP 00:02:00. (b2f2fda — @erichelgeson)
• Track boundary correctness — added cdrom_track_end_lba so READ CD splits transfers at track boundaries on multi-track discs instead of conflating BIN file size with track extent. (8f7e389 — @reinauer / @erichelgeson)
• READ HEADER (0x44) — parses LBA from CDB bytes 2-5 instead of always returning data for LBA 0; audio-track mode is written to the correct variable. (8f7e389 — @reinauer / @erichelgeson)
• READ CD I/O errors — seek() / read() failures now return CHECK CONDITION with MEDIUM ERROR / CIRC UNRECOVERED ERROR instead of silently returning corrupt data. (8f7e389 — @reinauer / @erichelgeson)
• WRITE AND VERIFY (0x2E) — returns ILLEGAL REQUEST on CD-ROM instead of silently performing an unverified write. (8f7e389 — @reinauer / @erichelgeson)
• getTrackFromLBA() without track_end_lba — corrected fallback for discs where the track end isn't known up-front. (389ce31 — @PetteriAimonen)
• Stale cdrom_track_end_lba across image changes — reset on CUE sheet reload and folder-based CD init. (b250f35 — @erichelgeson)
• Audio playback after CD change — stale cached trackinfo from the previous disc no longer causes read errors on the next disc; doSeek's audio call is guarded by bin_container.isOpen(). (b2ea073 — @morio)
• Audio with multiple CD-ROM drives — new play command stops all audio (id=0xFF) and reloads the cue when the audio owner changes; audio_last_status indexes by owner, not by passed id. Bus reset also stops audio. Applied to both I2S and SPDIF. (87cbe5b — @morio)
• Audio array sizing for wide SCSI — 8-entry audio arrays now sized for 16-target wide boards; ID masks corrected. (5611fc4 — @morio)
• Eject wrapping on multi-BIN/CUE — eject button now compares the container directory name instead of the inner BIN filename, so multi-BIN discs wrap back to the first image. (30ed064 — @morio)

Tape drive

• SPACE now uses absolute position and signed 24-bit count — per SCSI-2 §10.2.11, SPACE is relative to the current position and the count is two's-complement (negative = reverse). Previous code used an unsigned count and set tape_pos = count (absolute). (79432e3 — @erichelgeson)
• Variable-block READ underlength/overlength conditions — conditions were swapped. Per SCSI-2 §10.2.4 overlength is not an error; only underlength errors, and only when SILI is clear. (e4d81d4 — @erichelgeson)
• READ BLOCK LIMITS bad LSB byte — data[5] duplicated data[4], reporting min=0x0202 for 512-byte blocks. (7bdd5a8 — @erichelgeson)
• SPACE CDB byte extraction — was reading a 32-bit count across CDB[2-5] including the control byte. Now a proper 24-bit extract from CDB[2-4]. (7bdd5a8 — @erichelgeson)
• Variable-block READ/WRITE with transfer length 0 — per SCSI-2 §10.2.4 and §10.2.14, a zero transfer length is explicitly "not considered an error"; no data shall be transferred and the tape position is unchanged. (b6ed6b1 — @erichelgeson)

DaynaPORT / network

• AppleTalk slow under Virtual Memory on System 7 (#346) — multi-packet READ(6) is now gated on CDB byte 5 bit 6 (polled mode = 1 packet, blind mode = batched). Bus hold time stays short when the host's VM pager also needs bus access. Transfer size now respects the host's allocation length in CDB[3-4]. (7c20579 — @erichelgeson)
• Global INI strings no longer break DaynaPORT/AmigaWiFi — vendor/product/revision set under [SCSI] in bluescsi.ini are skipped for network devices, which require specific IDs for their drivers. Per-device [SCSIn] overrides still apply. (9f795a7 — @morio)
• WiFi (DaynaPORT) restored on CMake build — after the PlatformIO → CMake migration, CYW43 compiled from source needs PICO_CYW43_SUPPORTED=1, CYW43_WARN=//, cyw43_arch_poll() in platform_poll(), and our own cyw43_tcpip_link_status(). Tested on Pico 1W / Pico 2W with open and WPA2 networks. (4af22d7 — @erichelgeson)
• Ultra / Ultra Wide WiFi with GCC 14 — custom board headers and pico-sdk-internal v2.2.0-UltraSupport-rel2 work around a pico-sdk write-buffer ordering bug on Cortex-M33 that broke CYW43 SPI on Ultra hardware. (b0e1a4e, 79df606 — @erichelgeson)

Initiator mode

• USB MSC initiator no longer overrides hardware switch — when the SD card is absent, the hardware initiator switch setting is respected instead of being forced by USB MSC. (290f513 — @erichelgeson)
• Ultra initiator mode on some drives — timing tweak so initiator mode works against drives that were previously flaky on Ultra hardware. (2007324 — @androda)

SCSI core

• WRITE to read-only media returns DATA_PROTECT — per SCSI-2 §9.1.12 and Table 69, WRITE PROTECTED (ASC 0x2700) pairs with sense key DATA_PROTECT (0x07), not ILLEGAL_REQUEST (0x05). Some hosts branch on the sense key to distinguish "bad CDB" from "media write-protected" and retried incorrectly. (b9bd4af — @erichelgeson)
• REQUEST SENSE Valid bit only when Information field is meaningful — Valid (0x80) was set unconditionally and the Information field was always populated with transfer.lba, even for sense keys like ILLEGAL_REQUEST or UNIT_ATTENTION where no block address applies. Per SPC-2 §7.20, only MEDIUM_ERROR, HARDWARE_ERROR, and ABORTED_COMMAND now report Valid=1 with the LBA; other keys return error code 0x70 with a zeroed Information field. (f7feb1d — @erichelgeson)
• MODE SENSE reserved CDB byte 3 — non-zero values in the reserved byte (SPC-3+ SUBPAGE CODE) are now rejected per SCSI-2 §8.2.10/8.2.11 and SPC-2 §7.8/7.9, returning CHECK CONDITION / ILLEGAL REQUEST / INVALID FIELD IN CDB. (f914e04 — @erichelgeson)
• Packed scsiId field safety — S2S_TargetCfg::scsiId packs ID in bits 0-2 and the TARGET_ENABLED flag in bit 7. Introduced typed accessors and fixed a prefetch cache comparison that was missing the mask, causing bogus invalidations when the enabled flag differed between operands. (826b981 — @erichelgeson)
• scsiLogDataOut NULL buffer crash — data-out trace logging no longer crashes when the buffer pointer is NULL. (beaada1 — @morio)
• Stack overflow returning to IMG0 — refactor avoids the recursion that overflowed the stack when cycling back to the first image. (49b319f — @NT2MKU)
• Stack overflow during image init (RP2350) — stack sized and laid out to fit Audio SPDIF's peak usage. (887508b, 1851c05 — @erichelgeson)
• ROM drive flash-write crash on Ultra with WiFi — core1 mutex now protects flash writes during ROM drive loading so WiFi code on the other core can't be interrupted mid-flash. (15b7d10 — @PetteriAimonen)
• delay_ns() sub-microsecond accuracy — was rounding up by a full microsecond, making RST glitch-filter timing up to ~2× too long. Now cycle-accurate. (b2a0584 — @erichelgeson)

Timing / sync negotiation

• Sync rate alignment with target timing — synthesize the sync offer from the actual PIO transfer period so we advertise rates we can sustain. (4df54b5 — @reinauer)
• Custom timing overrides hardened — INI timing overrides are bounds-checked and validated before applying, so partial bad configs no longer take effect. (830acb4 — @reinauer / @erichelgeson)
• Lowered DMA read-pacer floors — faster sync: RP2350 14→13 cycles (~19 MB/s at 252 MHz), RP2040 18→15 cycles (~16.7 MB/s at 252 MHz). RP2040 18 had caused a 16→10 MB/s regression. (18283f0 — @erichelgeson)
• Overclocking suggestion threshold — only logged when sync speed is 10 MB/s, not at lower speeds. (f534dbf — @erichelgeson)
• TurboMax clk_hz corrected — 252 MHz → 250 MHz (an accidental change in 75d0b6b0). (74c61a0 — @erichelgeson)

SD card & storage

• SD card hot-plug with multi-BIN/CUE — scsiDiskCloseSDCardImages() now closes bin_container and resets image_directory, so "Already found an image directory, skipping..." no longer prevents images from loading after re-insertion. (e44445d — @morio)
• Geometry warning suppressed for >8 GB images — no more spurious C/H/S warnings on large disks. (f301988 — @erichelgeson)

BlueSCSI Toolbox

• Shared dir creation before file ops — onSendFilePrep, doCountFiles, and onListFiles now create the shared directory if missing and return CHECK CONDITION on failure, instead of silently writing to the SD root or continuing with no directory open. (581c6c7 — @erichelgeson)
• Zero-length SET_WORKING_DIR no longer hangs — CDB[8]=0 returns STATUS with no state change, matching the SCSI-2 convention that a zero parameter list length is not an error. Clients still reset the override by sending a 1-byte NUL path explicitly (CDB[8]=1, data=0x00). (1016cc8 — @erichelgeson, thanks @saybur)

Bootloader & boot

• RP2350 bootloader XIP cache guard — corrected a wrong #define name that left the cache unguarded during bootloader flash operations. (455510a — @erichelgeson)
• Bootloader log replay garbage — log_raw(buffer, len) was resolving to a template that printed the buffer as a string plus the length as hex (e.g. .0x000000A2) instead of a fixed-length copy. (ecb2ee5 — @erichelgeson)
• USB serial log missing on RP2040 — the CMake migration dropped Arduino-Pico's background USB timer, starving CDC enumeration during setup. A 1 ms repeating timer alarm now pends a software IRQ that calls tud_task() under __usb_mutex. Early-boot logs reach the serial console again. (7655af0 — @erichelgeson)
• Build timestamp showed "Jan 1 1980" — Nix's SOURCE_DATE_EPOCH was feeding __DATE__/__TIME__ the epoch. Now unset in the dev shell so firmware reports the real build time. (30ba8b1 — @erichelgeson)

Improvements

• Faster CD sector reads — when skip_begin == 0 (contiguous layout) we seek once before the transfer loop instead of per sector. (0d9ded1 — @reinauer / @erichelgeson)
• Quieter Vdd warnings — voltage-drop warnings deferred by ~1 s, suppressing noise during power-off and brief dips. (1b9bcc4 — @erichelgeson)
• C++ exception bloat eliminated — 31.8 KB of unused C++ exception tables trimmed from the RP2040 image, plus improved flash/RAM symbol placement. (81738d2 — @erichelgeson)
• Static stack usage analysis in CI — build pipeline now flags functions with large stack frames before they reach hardware. (2aa6130 — @erichelgeson)
• Application code built at -O2 — switched from -Os for better throughput on hot paths. (cb4da9e — @erichelgeson)

Build & infrastructure (user-visible)

• CMake + Nix flake build system — replaces PlatformIO. ./build.sh in a nix develop shell builds any target. See BUILDING.md. (1c41f99 — @erichelgeson)
• Release / pre-release tag handling — firmware build workflow now distinguishes release vs. pre-release tags for cleaner release management. (315b208 — @erichelgeson)
• Note bundled inside firmware ZIP — create_firmware_zip.sh and make_dist.sh now embed a short user-facing note inside the distribution zip explaining the new universal-update flow. (71dbfb1 — @erichelgeson)
• minGlue.h include guard — adds #ifndef MINGLUE_H so test stubs can shadow the header; unblocks x86 unit testing for minIni glue. (4a3a15e — @erichelgeson)
• macOS build support — flake and build scripts updated so macOS hosts can build the firmware. (8d1794b — @erichelgeson)
• Pico SDK pinned to v2.2.0-UltraSupport-rel2 — includes the upstream CYW43 SPI driver, PIO0 force for RP2040, and clock GPIO function fix. (79df606 — @erichelgeson)
• PlatformIO/Arduino remnants removed — leftover board JSON files, build scripts, and library manifests cleaned up. (e291c2e — @erichelgeson)
• Handle new bootloader_size in linker scripts — needed for the reshaped bootloader with shared log region. (39aee65 — @erichelgeson)
• PR memory-usage comment — CI posts a memory diff against the latest GitHub release on each PR. (db5dbe9 — @erichelgeson)
