The terminal process "/bin/bash '-c', 'make -f '/home/andrew/.particle/toolchains/buildscripts/1.9.2/Makefile' flash-user -s'" terminated with exit code: 2.

I’m not quite sure what I did to get to this point. Trying to flash just the application or both deviceOS and application gives me the same error.

I then tried flashing Tinker as a test, and the command “particle flash --usb tinker” reports Flash Success, but it doesn’t actually load Tinker on the device.

Does this not make you wonder

@AndrewM

make[1]: *** [modules/photon/user-part] Error 2

When you are building for Photon don't be surprised when that doesn't stick on a Boron

Thanks!

In case you tried the -force switch to hammer the incompatible FW into the device you may need to use particle update -v to get the device back into a sane state. This will also set the device OS version to 1.5.2 if you weren’t on that already.
