The generic arm64 image prints another product's banner/motd/login line
during boot, before guestSetup can re-brand the guest. Boards with
quietBoot show a neutral '[Velxio] Booting <label> (Linux guest)...'
progress line (dots every 4 s) while boot detection and the prompt-gated
upload still run underneath; the shell is revealed (already re-branded)
right before the auto-run command, so the user's first visible output is
their own program.
- ProBoardDef.autoRun: after boot (+guestSetup) the VFS uploads itself
and the command runs, so a single Run click boots, uploads and starts
the user's script (same UX as compiled boards)
- ProBoardDef.guestHome: VFS home dir override ('/root' for guests that
log in as root); those boards drop the historic hello.sh sample
- upload sequence extracted to utils/piUpload (shared by the VFS panel
button and autoRun)
- serial monitor strips DEL/C0 control echoes (backspace showed tofu)
Overlay QEMU-Linux boards are not Raspberry Pis: ProBoardDef.guestSetup
lets a board send one shell line at the boot prompt (hostname/PS1/clear)
to de-brand the generic image, sent before piBooted flips so uploads
cannot interleave; the workspace start button and power-on title carry
the board's own label for non raspberry-pi kinds; the compile console
line uses the board label instead of 'Raspberry Pi 3B'.
registerPiFamilyKind + ProBoardDef.piFamily route an overlay board through
the existing Raspberry Pi bridge path (WebSocket qemu, VFS panel, boot
terminal); register_pi_board_profile lets the overlay add the matching
PI_CONFIGS entry (cpu/image_set/...) at registration time.
The @pro overlay import is dynamic, so board/component registration can land
AFTER the picker mounted and memoized its lists. allBoards had frozen deps —
if the picker rendered first, overlay boards (M5Stack Core, Cardputer,
Pimoroni, C6) vanished for the whole session while their ONLINE ads were
already hidden; the component grid + ONLINE component ads flipped between ad
cards and real entries depending on who won the reload race (different SVG,
ONLINE badge appearing and disappearing, wrong hover thumbnail).
proBoardRegistry and ComponentRegistry.mergeComponents now bump a version and
notify subscribers; the picker's allBoards / filteredComponents /
visibleComponentAds memos key off those via useSyncExternalStore — same
contract as proRoutes and registerProExamples.
Boards with built-in hardware (LCD on the element's own canvas, speaker,
on-board buttons/keyboard) need run-time wiring between the DOM element and
the board's simulator shim / ESP32 bridge. One generic SimulatorCanvas effect
now hands those handles to the overlay's attachBuiltins shortly after run
start and runs its cleanup on stop — no board names in the OSS tree.
registerProBoards() lets a hosted overlay ship boards outside the OSS tree as
data-only definitions: registration patches the exported BoardKind maps
(labels / FQBN / MicroPython) so every existing read site keeps working, and
the sites a map can't cover consult the registry — canvas render (custom
element or overlay render fn), BOARD_SIZE, pin-name mapping, picker list +
descriptions + tag, ESP32 family routing, in-browser simulator construction
and firmware load (structural ProBoardSimulator contract, duck-typed PIO
attach/detach), built-in bridge sensors, and a CS-gated built-in microSD
(sdCsPin -> sd_card.cs_pin worker config). Esp32Bridge additionally gains the
esp32-c6 machine type + TX pin (public chip knowledge — the C6 compile path
already ships) and a generic sendKey() for built-in matrix keyboards.
registerProExamples() appends gallery examples at runtime; the board ONLINE
ads recompute at render so registration hides them. OSS behavior without an
overlay is unchanged — the registry is dead code, same as the other seams.
