[SOLVED]Particle flash error "Error writing firmware...no known App found."


I’m trying to flash photon from command line with command particle flash --usb photon test.bin

It gives me the error:

Found DFU device 2b04:d006

Error writing firmware...no known App found.

I’m always programming like that. What changed and I see that error suddenly?

Try leaving out the ‘photon’.


Thanks solved my problem.

No problem. For future reference: https://docs.particle.io/reference/cli/#compiling-remotely-and-flashing-locally
