Argon fast flash green- USB serial ouput issues on a single unit

Hi all,
I’m having some particularly weird behavior with a single argon (out of 4: Let’s call him BOB). I’ve successfully paired it via the app (using the ethernet featherwing), seen it on the particle cloud- but after flashing my application, the device gives the fast flash green “Looking for internet” indication on this particular unit (and does not provide any debug information via usb serial communication) - pretty much regardless of it is connected to a network or not. Same PC, same cable, same software, same setup, other 3 argons: serial debug works, and the device is in dark blue blinking “Listen mode” waiting for a DHCP server to respond.

Now for even more fun, I can successfully put cloud debug on BOB, and can see the results (either via the terminal on the cloud debug page or via a terminal/monitor program)- but flashing my own application goes back to the same behavior: nothing shown and green blinking LEDs.

I’ve tried going through the setup/initialization process again through the app- BOB can connect to the cloud- but again fails after flashing.

I’m not happy with BOB right now.

adding a log from cloud debug:

So, after cloud debug was installed via Chrome, again tried to flash the application & device OS from Workbench. It claimed success - but when coming back up, the cloud debug application was still loaded. Wasn’t paying attention to the LEDs after it went into DFU mode, so can’t say much of anything about that.

Hmm.

Oh for the love of pete’s pickled peppers… closing VSCode and opening it again resolved the issue. Able to flash without problems.

Note to future self: if anything seems to be behaving weird, just close the gdarned VSCode and start it up again before digging any deeper into it.
