An address of Configuration for USRP2 device 0: Configuring the slave In order for the slave to synchronize to the master over MIMO cable, the following clock configuration must be set on the slave device: The microcontroller prints useful information about IP addresses, MAC addresses, control packets, fast-path settings, and bootloading. Use the overwrite-safe option the first time, and then repeat without it for the second time. Cards can have unexpected timing characteristics.

Use the --list option to get a list of possible raw devices.
This or a comparable JTAG programmer should enable device recovery. When setting up a development machine for the first time, you may have various difficulties communicating with the USRP device.
N/N Device Recovery - Ettus Knowledge Base
Use a standard USB to 3. In any case, each Ethernet interface should have its own subnet, and the corresponding USRP2 device should be assigned an address frmware that subnet. Using an external 10 MHz reference clock, a square wave will offer the best phase noise performance, but a sinusoid is acceptable. Continue to hold-down the button until the front-panel LEDs blink and remain solid.
N200/N210 Device Recovery
Configuration for USRP2 device 0: Determine the revision number from the sticker on the rear of the chassis. Don't forget to power-cycle the device after it has been girmware.
Using a PPS signal for timestamp synchronization requires a square wave signal with the following amplitude:. The LEDs on the front panel can be useful in debugging hardware and software issues. The device address parameter keys must be suffixed with the device index. The microcontroller prints useful information about IP addresses, MAC addresses, control packets, fast-path settings, and bootloading.
If the device is an N2xx or X3xx series radio, this syntax loads the default images to the radio at IP address Name must appear inside quotes.
Warning When burning images with the card burner, it is possible for you to overwrite your hard drive. This page was last modified on 23 Aprilat This ensures that when the device reboots, it has a compatible set of images to boot into.
If this is the case, we recommend that you disable the firewall or create a rule to allow all incoming packets with UDP source usro If the answer to any of the questions listed below is "no", then there is probably a hardware problem.

You can specify several name and value pair arguments in any order as Name1,Value1, Use the image loader Use default images: Retrieved from " https: Ettus Knowledge Base Ettus.
To boot into the safe image, hold-down the safe-mode button while power-cycling the device. This hardware has only one daughterboard slot, which has been aptly named slot A. The RXD pin can be left unconnected as this is only a one-way communication. The first step is to flash the unit's safe-mode image, and then do a normal flash - both with the UHD Image Loader utility.
Device recovery and bricking Its possible to put the device into an unusable state by loading bad images. All Rights Reserved Other product and company names listed are trademarks or trade names of their respective companies.
USRP Hardware Driver and USRP Manual: USRP2 and N2x0 Series
For maximum throughput, one Ethernet interface per USRP2 is recommended, although multiple devices may be connected via a Gigabit Ethernet switch. The LEDs reveal the following about the state of the device:. External clocking is optional and should only be supplied to the master device. Multiple devices per host For maximum throughput, one Ethernet interface per USRP2 is recommended, although multiple devices may be connected via a Gigabit Ethernet switch.
The first step is to flash the unit's safe-mode image, and then do a normal flash - both with the UHD Image Loader utility.
