ESP-IDF Compilation Service for ESP32 targets.
|
|
|
|
Replaces arduino-cli for ESP32/ESP32-C3 compilation. User Arduino sketches
|
|
are compiled using ESP-IDF (with optional Arduino-as-component) to produce
|
|
firmware that boots reliably in the lcgamboa QEMU fork.
|
|
|
|
The key difference vs arduino-cli: ESP-IDF gives control over bootloader,
|
|
sdkconfig, and flash mapping — all of which must be QEMU-compatible.
|
|
|
|
Two compilation modes:
|
|
1. Arduino-as-component: Full Arduino API (WiFi.h, WebServer.h, etc.)
|
|
compiled through idf.py. Requires ARDUINO_ESP32_PATH env var.
|
|
2. Pure ESP-IDF: Translates common Arduino patterns to ESP-IDF C APIs.
|
|
Fallback when Arduino component is not installed.

Build dir layout:
|
|
- With VELXIO_PERSISTENT_BUILD_DIR=1 (default): a per-target dir at
|
|
/var/lib/velxio-build/<idf_target>/project/ is reused across compiles.
|
|
ninja's incremental cache + ccache hits combine to bring warm
|
|
compiles down to ~5-30s.
|
|
- With VELXIO_PERSISTENT_BUILD_DIR=0: legacy tempfile.TemporaryDirectory
|
|
flow. Every compile rebuilds from scratch.
|
|
|
|
The caller (routes/compile.py:_compile_job) holds a per-target
|
|
asyncio.Lock for the duration of this call, so the persistent dir
|
|
is never accessed by two compiles at once.
|
|
|
|
progress_callback (optional): if provided, called from a worker
|
|
thread for every stdout/stderr line as cmake and ninja run. Used
|
|
by the async compile path to expose live build output to clients
|
|
polling /api/compile/status/{job_id}.
|
|
|
|
board_options (optional): per-board ESP32 build options from the
|
|
UI (Partition Scheme, CPU Frequency, Flash Mode, PSRAM, etc.).
|
|
Missing keys fall back to historical defaults so AVR/RP2040 callers
|
|
and pre-feature clients still get a working build. Note that
|
|
SPIFFS files are NOT folded into the cache-invalidation hash —
|
|
only sdkconfig-affecting options are — because the SPIFFS image is

rebuilt on every compile anyway and folding it in would burn the
