[BUG] Error building on Linux

[pierrep]

Excellent, I was hoping you'd be prompt and I wasn't disappointed! I'm highly in need of your "iterative" function to program multiple xenons. I was in the process of rolling my own then came across your project....this will save me a lot of time...thanks!

[pierrep]

FWIW, I get this when creating a new project as well.

Hey @pierrep,

This bug likely occurred because your ~/.neopo/cache/manifest.json file was not populated correctly during installation because the Particle dependencies were likely already installed from Workbench. I will push a fix for this soon.

In the meantime, can you try doing a forced installation of dependencies?

$ neopo install -f

[nrobinson2000]

I have pushed a fix for this. It appears that when dependencies were skipped during the installation they were not added to manifest.json. I have corrected this behavior.

Upgrading neopo and installing dependencies without -f should fix your issue.

$ neopo upgrade
$ neopo install

[pierrep]

OK I ran

$ neopo upgrade
$ neopo install

and everything works fine now. I flashed 4 Xenons with a single

neopo iterate flash

command. Huge thanks...I have around 35 devices, so this was critical to solve.

Just a couple of other random questions while I'm here.
I was using your code to enter DFU mode, but it was only working by setting the baud to 14400 and then to 9600 again. Is that normal??

Also, I'd REALLY love a homebrew solution to OTA programming. I see that you've dug into the toolchain a fair bit....do you know if this is remotely feasible? If so, I'd love some pointers. It's more for the longer term as I'm making an art installation from my Xenons and it'll be a huge pain to reprogram them via USB once they are installed.

On Linux I’ve seen this behavior when using that C program. I’ve had better luck using pyserial.

However, lately with deviceOS you can use Particle CLI to put devices into DFU. I’ve included access to the Particle CLI executable used within neopo.

$ neopo particle usb dfu

I’m not sure it’s possible to create a homebrew OTA. Maybe you could slap some Raspberry Pi zeros onto the Xenons and use neopo over SSH?

[pierrep]

Yeah I'm aware of particle usb dfu, I currently have a shell alias for it. I was just wondering about that weird behaviour.

Thanks anyway...RPI's would defeat my low energy budget, and there's already an RPI solution here. I was just wondering how Particle do it through the Cloud, if there was any published info on that...but I'm guessing not.
