I need to use N200 for a project. However, its LED D does not lit up
(no firmware) and no response when pinging through the Ethernet
connection. Followed the instruction on Ettus website to unbrick this
N200 and here is what I got (from a Windows 10 laptop computer).
With an Xilinx Platform Cable, I was able to use Xilinx Impact to
load “|usrp_n210_r4_fpga.bit”| via the programmer. LED D was lit up
now and Ethernet connection was established as I can ping and get
response from N200.
Then I was also able to use MATLAB to load the firmware and FPGA
images to N200. The operation was successful and I was able to find
the device in MATLAB and read back the device status info.
However, after power-off and power on again, N200 went back to the old
dead condition again. It looks like the firmware was not permanently
burned into the device EEPROM as it is supposed so.
I may have missed one step or two. Any suggestions?
Thanks,
Chun
It's likely that it's just an IP address issue. When in "safe mode",
the device adopts a standardized IP address. But once you power-cycle
out of "safe mode",
it'll take on whatever is programmed into the EEPROM for its IP address.
Bring the device back into "safe mode", and use the usrp_burn_mb_eeprom
utility to program your desired IP address while the device is in safe
mode, using the default safe-mode address.
