TEST: Enable ulab and attempt to catch app/filesystem overlap
Try to enable ulab for additional builds.
TODO: Most of the required tooling changes to know if ulab builds will work or not have been moved to https://github.com/pimoroni/pimoroni-pico/pull/927 which needs merged and this PR rebased.
Generally it seems additional ulab builds are... unlikely... but we can always monkey with the filesystem size for people who really want to make that tradeoff.
:warning: There's a pimoroni-pico build in this PR/branch which adjusts the memory split from 640k/1408k to 1024k/1024k. This makes room for ulab and perhaps other things, but since the filesystem has moved, it is not compatible with our Pico or the stock Pico build. :sparkles: Back up your files! :sparkles:
Cool cool, despite checking it twice I had my app/filesystem sizes backwards...
Results... uh, the prognosis 🦉 is not so good:
| Board | Avail | Used | Usage | Note |
|---|---|---|---|---|
| Pico | 640k | 723k | 112.96% | ulab wont fit |
| Pico W | 1200k | 1192k | 99.34% | ulab just fits |
| Tiny 2040 | 640k | 610k | 95.38% | no ulab or custom linker, percentage calculated |
| Galactic | 1200k | 1124k | 93.67% | ulab just fits, and we currently ship with it! |
| Cosmic | 1200k | 1124k | 93.66% | ulab just fits, and we currently ship with it! |
| Stellar | 1200k | 1124k | 93.66% | ulab just fits, and we currently ship with it! |
| Inky Frame | 1200k | 1071k | 89.25% | ulab... might fit? |
Using py_decl to analyze .uf2 files post build has replaced the method used here.
