- CORE.firmware_bin priority is now platform-aware: RP2040 + libretiny
prefer firmware.uf2 over firmware.bin (picotool / ltchiptool need the
UF2 header for address/family info); ESP* prefer firmware.bin. The
prior code returned .bin first for all platforms, which would have
silently flashed the wrong artifact on RP2040 if a hand-staged dir
shipped both files. New tests guard both directions.
- _rp2040_serial_reset_to_bootsel: check picotool exists *before*
triggering the 1200bps touch. If picotool is missing, the touch
would have left the device stranded in BOOTSEL with nothing able to
flash it; with this order the device stays on the old firmware and
can be retried.
- upload_using_ltchiptool: error message now mentions both firmware.uf2
and firmware.bin since CORE.firmware_bin resolves either.
- prepare_platform_for_upload: return type tightened to int (capture_stdout
is hardcoded False; assert the run helper returns int so a future caller
that flips capture_stdout fails loudly instead of silently treating a
string as success). Caller in __main__.py is now a one-liner.
- _load_idedata: narrative comment in the prebuilt branch shortened.
_resolve_prebuilt_idedata_paths docstring now notes the
POSIX-absolute-on-Windows quirk ("/foo/bar" is rooted but not absolute
on win32; hand-staged dirs need OS-appropriate absolute paths).
- New defensive-coverage tests: _resolve_prebuilt_idedata_paths with
missing prog_path, no extra section, empty flash_images list.
