I just tried it and ran into some trouble on the reinstall apps step. After reinstalling many apps the watch decided to start compacting when it came to I did this from within gadgetbridge. Fw update from official app loader and reinstall apps via development app loader. Edit: I think I had ca 50 apps installed while doing this (essentially the |

... yes, I just tried and that's the problem. I'll try and get a fix done in an hour or two. I'm thinking that rather than trying to force compaction on Bank 1 (which could make things slow each time something is written) maybe we just immediately put the file in external flash if there's room? |

Very nice, but isn''t this an old feature? I used to use C on the P8 like so: |

It is, yes - the issue was it was broken before, so if you ever had to compact the internal storage it'd get corrupted and lose most of the contents :) |

nice, it is working fine on the p8 since some years now, compacting was no problem, I have like this on the repo for the main js files, but I guess it broke after 2.15? Can I use C on the bangle.js 2 now, or is it done automatically? |

That's strange. Maybe it did - it'd be interesting to see when the multiple write code went in. The error seems to be when writing more than 2k at once You mean inline C? Yes, it should 'just work' for the ide as well as apps in the app loader |

Sorry, I meant can I choose if the file will go to the internal flash using the C: method? |

Ahh, yes - that method works now (it's just ignored on builds that don't have 2 flash areas). |

To date, Bangle.js 2 has stored all its apps on a filesystem on the 8MB external flash, which has worked pretty well but is slower than it needs to be.
There's 1MB of internal flash which has to store the Bangle.js firmware, but also has a bit of free space (currently ~250kB). If we put the JS in internal flash and everything else in external flash, apps will load much faster.
... so that's what I've done. We tried it a year ago and a mysterious bug meant the internal flash suffered some corruption and it was too broken to use, but I've just fixed that and everything appears to be ok now.
I've attached the firmware here - you can update it via the app loader at https://banglejs.com/apps/?id=fwupdate by clicking 'Advanced' and uploading the ZIP: espruino_2v25.424_banglejs2_iflash.zip but please do a backup first!
edit: updated firmware
Once installed you'll have to choose 'reinstall apps' from the app loader to force the JS from the apps to be loaded into the internal flash. If you switch back to a 'normal' firmware you'll have to do the same just to make it work (as all JS will then have been lost!).
Please backup before you try this! and I'd advise not doing it on a watch you need to use every day just in case there are issues.
... but having said all that, this does feel an awful lot faster than before, and if it really does work smoothly it might be something that I make the default in the future.
