The Ettus 210 has become unreachable through pings after changing its IP address. I flashed the EEPROM (as shown below) and then re-powered the radio. The radio should be reachable this way, but has become bricked. When the N210 was on a different VLAN, I could ping it just fine, but is now unreachable with this new IP.
What should I try next to fix this N210? > $ ./usrp_burn_mb_eeprom --read-all > > Creating USRP device from address: > > \[INFO\] \[UHD\] linux; GNU C++ version 9.4.0; Boost_107100; > UHD_4.8.0.HEAD-0-g308126a4 > > \[INFO\] \[USRP2\] Opening a USRP2/N-Series device... > > \[INFO\] \[USRP2\] Current recv frame size: 1472 bytes > > \[INFO\] \[USRP2\] Current send frame size: 1472 bytes > > \[WARNING\] \[UDP\] The send buffer could not be resized sufficiently. > > Target sock buff size: 2500000 bytes. > > Actual sock buff size: 1048576 bytes. > > See the transport application notes on buffer resizing. > > Please run: sudo sysctl -w net.core.wmem_max=2500000 > > \[WARNING\] \[UDP\] The send buffer could not be resized sufficiently. > > Target sock buff size: 2500000 bytes. > > Actual sock buff size: 1048576 bytes. > > See the transport application notes on buffer resizing. > > Please run: sudo sysctl -w net.core.wmem_max=2500000 > > \[WARNING\] \[UDP\] The send buffer could not be resized sufficiently. > > Target sock buff size: 2500000 bytes. > > Actual sock buff size: 1048576 bytes. > > See the transport application notes on buffer resizing. > > Please run: sudo sysctl -w net.core.wmem_max=2500000 > > \[WARNING\] \[UHD\] Unable to set the thread priority.
