Hi all,
I have a problem trying to power up the USRP E320.
When I push the power button, the power led doesn't light up and the
eth leds blink for a few seconds and then shut down. This is not the
first time this has happened to an E320 device (for the other cases I
recovered them by pushing the button longer or enter to the serial
port to reboot) but now it seems like trying the things I did before
does not work.
I connect the serial port to my PC and see this every time I push the
button:
- ARM CPU (stuck in that step)

- Microcontroller:

The ARM CPU does not allow me to log in, but from the microcontroller,
I can run commands. I try to reboot the device from it, but it always
says this line:

Is this a known issue? I haven't tried anything strange, I always shut
them from the ssh connection so this happens by chance. I'm sure it is
not broken just stuck in the boot state, but I don't know which are
the right steps to start it up.
Any help will be appreciated.
Kind Regards,
Maria
I don't have an E320, so this is a "shot in the dark" type of
answer--you could try refreshing the system image:
