Hi,

So I boot off of the Live DVD (3.7.4), and try GRC with an X310 and get  
an error about the firmware version being 3, when 4 was expected.

I then use usrp\_x3xx\_fpga\_burner to update the firmware, which after a  
few minutes of updating, I still get the same error with GRC?

What am I doing wrong, is there a different firmware update required, or  
is the DVD version wrong, please?

Thanks,  
David

Did you power-cycle the device after updating the firmware? The  
contents of flash are loaded into the FPGA on a reset, which happens  
at power-cycle, just like N2xx as far as I know.

David -

Be sure to wait until the burner utility TELLS YOU IT IS COMPLETE.

If you power-cycle in the middle of the burn, it’s a great way to brick  
your device. If you have bricked your X300, you can recover it using the  
JTAG port on the front panel.

Cheers,  
Ben

David hangs up his network cable and sighs…  
"yeah, power cycle it, like it says after burning! "  
Sorry,  
Thanks All.
