Hi,
I am trying to measure IQ Imbalance of USRP N210 with WBX daughterboard:
After running *uhd_cal_rx_iq_balance*, I got following error:
*Error: This dboard has no serial!*
*
*
*Please see the Calibration documentation for details on how to fix this*

USRP Probe output:

The documentation on
http://files.ettus.com/manual/page_calibration.html#calibration_self
suggested burning serial number into daughterboard's EEPROM. After
running
*/usrp_burn_db_eeprom --ser=N210105 *
I got following error:
*Error: LookupError: Path not found in tree:
/mboards/0/dboards/A/_eeprom *
Please let me know how to resolve this issue.
Thanks,
Kunal
It looks to me like you don't have an N210 there, but rather a USRP2.
With a WBX whose EEPROM has failed.
