track(platform): assess W600 FastLED build support #390
Description
Context
FastLED/FastLED#1178 asks whether FastLED can support the W600 platform similar to ESP. This is a distinct platform request and needs a fbuild tracker so support is either implemented, scoped, or explicitly marked out of scope.
Source FastLED issues
- Would it be possible to add support for the W600 platform similar to esp? FastLED#1178 - Would it be possible to add support for the W600 platform similar to esp?
Acceptance criteria
- Determine whether fbuild has any usable W600 board metadata, Arduino core package path, and toolchain support.
- If support is feasible, add a representative fbuild smoke fixture and build a minimal FastLED sketch far enough to prove platform detection/build setup.
- If support is not feasible, document the missing toolchain/core pieces and keep the source FastLED issue linked to this blocker.
- Comment back on the source FastLED issue with the fbuild assessment.

Assessment: not feasible, closing as not planned
Investigated W600 (Winner Micro W60x) support across fbuild, PlatformIO, Arduino, Zephyr, and probe-rs. Posted full write-up on the source issue: FastLED/FastLED#1178 (comment).
Summary
fbuild-build/src/w600/Cortex-M3 orchestrator with a custom SDK whole-archive link andwmtoolsflash integration.wmtoolsflasher is Windows-.bat-only.platform-winnermicroupstream (404). No third-party platform survives.uv run python ci/board_sources.py --search w600and--search winnermicro): zero hits across Arduino official, ESP32, ESP8266, Adafruit, SparkFun, Teensy, and Zephyr indices.src/platforms/arm/w600/stub exists either.Decision
Closing as not planned. Reopen if a maintained W60x Arduino core with a modern
arm-none-eabi-gcctoolchain and a non-Windows-only flasher appears upstream, and FastLED grows a platform stub.No fbuild code changes were made for this tracker.
