Can my sketch prevent a Flora's future uploads?

Post by gigglingcorpse »

A week or so ago, I received two Floras in the mail and they've been great. Everything worked without issue.

But today everything went wrong.

Using the Arduino IDE, I can no longer upload code to either. I've tried on two machines; both I can confirm worked prior. I've tried multiple USB cables and ports, including once that previously worked.

I've read a lot of similar posts, but none really seemed to help. It's likely I'm just being dumb - still, any help would be appreciated.

A little more information: after the first one stopped working, and I swapped things in and out, I switched to the second. It worked. I was able to upload a test sketch. I was then able to upload the code I'd previously been working on. I made a small change to said code, and from that point forward could no longer upload.

So the immediate culprit that comes to mind is I've done something silly in my code. Does that seem possible? If so, is there a way back from there? (I'm mentally preparing myself to be terribly embarrassed.)

Here's the verbose upload ouput:

Ha! I was finally able to time my reset clicks to successfully coincide with the upload, and now both can take sketches again. Things are looking up! (Now to figure out what in my code was causing this.)

Update: It looks like it may have been a superfluous delete - I forgot to remove one that was no longer necessary.
