Mirror the libretiny/ltchiptool shape for RP2040 serial when
--prebuilt-dir is set: open the user-supplied serial port at 1200 baud
(arduino-pico's USB CDC interprets the open/close as a request to reboot
into BOOTSEL), poll picotool until the BOOTSEL device shows up on the
USB bus, then dispatch to upload_using_picotool with the prebuilt .uf2.
This removes the last path that required --prebuilt-dir to contain a
platformio.ini + .pioenvs/<name>/ tree, so upload_using_platformio is
now only invoked when no prebuilt dir is set (i.e. the existing
compile+upload flow on a developer machine).
Issue: esphome/device-builder#572
The libretiny upload path on `upload_program` SERIAL dispatch re-invokes
PlatformIO (`pio run -t upload -t nobuild`), which needs a full build
tree and `platformio.ini`. That makes it incompatible with a dashboard
that only has prebuilt artifacts.
Bypass PlatformIO for the libretiny+SERIAL+--prebuilt-dir case by calling
`ltchiptool flash write -d <port> <firmware.uf2>` directly. The .uf2
encodes the chip family in its header so no extra config is needed.
ltchiptool ships with the libretiny PlatformIO platform under
~/.platformio/penv/.libretiny/bin/ltchiptool; `get_ltchiptool_path()`
prefers PATH first (pip install ltchiptool) and falls back to the
PlatformIO penv. Without --prebuilt-dir the existing PlatformIO path
remains in place, so this is purely additive.
Issue: esphome/device-builder#572
Adds a --prebuilt-dir flag to esphome upload that points the per-platform
upload helpers at a directory of prebuilt artifacts shipped from a paired
build server, instead of re-deriving paths from the local build tree.
Covers every upload-dispatch shape:
- ESP32 / ESP8266 serial (esptool) reads firmware.bin + extras via the
prebuilt idedata.json the dashboard ships next to the artifacts.
- ESP32 / ESP8266 OTA (native API + web_server) reads CORE.firmware_bin,
CORE.partition_table_bin and CORE.bootloader_bin which now consult the
prebuilt-dir first.
- RP2040 BOOTSEL (picotool) falls back from the idedata ELF (absent in
the flat layout) to the prebuilt firmware.uf2.
- RP2040 serial / libretiny serial / OTA (PlatformIO upload -t nobuild)
point platformio at the prebuilt build tree via CORE.build_path so the
-t upload -t nobuild path finds platformio.ini and .pioenvs/<name>/.
