Fully regenerate .boot0 from scratch?

[RKBoss6]

I've recently been tinkering with bootloader scripts, and I noticed that when I upload a new version of that code from IDE, the watch would update boot0, but sometimes would corrupt a line or two from what I can see? What happens is the watch gives errors unrelated to what I uploaded, for example, if I upload a bootloader script for animating loading, it will return an error in the IDE that sleeplog.global is undefined. Same thing with different code, just different unrelated errors. I pushed through that by reuploading, but now many boot scripts are broken on my watch, and it is behaving erratically. I'm wondering, is there a way to fully regenerate the .boot0 file from scratch, hopefully mitigating these errors that have compounded?

EDIT: I found out that just erasing boot0 and running bootupdate will fix it, but I'm still getting an error that I have no idea to decipher, and cannot debug, as all of boot0 is minified and pretokenized.

Can you:

1. look at the .boot0 file

2. Decode JS

3. Copy to editor

4. Inspect your .boot0

• Is it really 641 lines long? (as I think at eval (.boot0:641:9) star[ERASED] indicates) Mine is 32 lines long.
• Is it suddenly cut of at line 641 character 9?

You can regenerate boot0 just by running setting-utils-rewrite settings.

.. But sounds like a really strange problem. Possibly one of your files is corrupt and that is making boot0 broken?

You can also enable some boot0 debugging by setting bootDebug:1 in setting.json, and that could really help

[gfwilliams]

Try:

require("Storage").writeJSON("setting.json", Object.assign(require("Storage").readJSON("setting.json",1),{bootDebug:1})); load();

You can also choose not to pretokenise in the app loader and "reload apps" to load all the apps without them being pretokenised - but to be honest reloading all the app code might fix it anyway

Hmm, as of right now, the watch is usable for me, so I might keep it for a bit - I have a ton of custom app modifications that I don't want to see gone if I reinstall all apps. I'll look into the boot0 debugging, though.

[RKBoss6]

I tried that, and no files that ended in .js were listed, only .log, .raw, and .img files were listed...

[gfwilliams]

Strange - perhaps it's file that has something missing from the middle? Please could you post your .boot0 (as downloaded from the IDE) here? It will only include code, not personal data.

[RKBoss6]

I'm still getting the error, even after reinstalling all apps...

[gfwilliams]

I've just deleted the file you included as it was huge! Next time it'd be great if you could attach it rather than including verbatim as it's actually easier for me to search for the damaged bits.

But in it, there's:

...ÿ ÿ ÿ ÿ ÿ;print("sleepsummary.boot.js",0|...

So your issue is with sleepsummary.boot.js - if you reinstall sleepsummary it should fix it, or you can just delete sleepsummary.boot.js to fix it...

Ok thank you so much! Is it the ÿ characters that are causing that?
