Local cloud flash firmware error


I am using the local cloud in a raspberry linux server and it works great, I’m trying to put an application in spark core that is properly with local keys and paired with the server. I put the core LED flashing yellow, and use the command

spark flash 89472384723894789 firmware.bin

after 4 minutes get error that occurred timeout.

I tried with the connected USB and wifi

What can be the problem?

For usb, the command is spark flash --usb xxxx.bin

The command you are using is for OTA firmware flashing and the core will need to connect to the :cloud:

Using usb command I receive this message

Filter on vendor = 0x1d50 product = 0x607f
Cannot open device
Opening DFU capable USB device... Error writing firmware...

found the solution need a sudo before
