[USRP-users] Problems with Ettus B210 and Intel Nuk

Hi Tathagata,

After you boot, if you run: $UHD_INSTALL_PREFIX/utils/b2xx_fx3_utils --reset-device

Are you able to then initialize the USRP by running uhd_usrp_probe?


Regards,
Nate Temple

The attached document details the debugging steps that we have taken and the errors that we are getting.  We never had this problem before and it suddenly started and we have no clue as to what is going wrong. Any help would be highly appreciated.
