sdruload

Load FPGA and firmware images for USRP radio

Add-On Required: This feature requires the Wireless Testbench™ Support Package for NI™ USRP™ Radios add-on.

Syntax

sdruload(Device=radioDevice)

sdruload(Device=radioDevice,IPAddress=radioIPAddress)

status = sdruload(___)

Description

sdruload loads the default FPGA and UHD™ firmware images to a USRP™ N3xx or X3xx series radio that is connected to the host computer; for 200-series USRP radios, see the Communications Toolbox™ documentation. For details, see sdruload.

sdruload(Device=radioDevice) loads the default FPGA and UHD firmware images for the specified device, Device, to a radio at the default IP address, 192.168.10.2. If your radio is not at the default IP address, use an alternative syntax to specify the IP address.

The default FPGA image provided by the hardware vendor is used to enable Wireless Testbench™ Live Data I/O features. Firmware images are the UHD versions compatible with Wireless Testbench Support Package for NI™ USRP Radios. You can obtain the compatible UHD version number using the getSDRuDriverVersion function.

sdruload(Device=radioDevice,IPAddress=radioIPAddress) loads the default images for the specified device, Device, to a radio at the specified IP address, IPAddress.

status = sdruload(___) returns the status information of the call to sdruload.

Examples

Load Default FPGA Image to USRP Radio

Load the default FPGA and firmware image to a USRP radio and return the status of the operation.

status = sdruload(Device='N320',IPAddress='192.168.20.2')

Input Arguments

Device — USRP radio

'x300' | 'x310' | 'n300' | 'n310' | 'n320' | 'n321'

USRP radio, specified as one of the following options:

• 'n300' — A connected USRP N300 radio.

• 'n310' — A connected USRP N310 radio.

• 'n320' — A connected USRP N320 radio.

• 'n321' — A connected USRP N321 radio.

• 'x300' — A connected USRP X300 radio.

• 'x310' — A connected USRP X310 radio.

Example: Device='x310'

IPAddress — IP address where the radio is located

dotted-quad character vector

IP address where the radio is located, specified as a dotted-quad character vector. Specify a valid IP address for a radio that you have connected and set up using the Radio Setup wizard.

If you changed the IP address from the default when you set up your radio, use the radioConfigurations function to find the IP address.

Example: IPAddress='192.168.10.2'

Output Arguments

status — Status of call to sdruload

logical

Status of call to sdruload, returned as a logical value. status is returned as true if the FPGA image and firmware image load is successful.

Tips

Use the sdruload function to reload the default hardware image onto your radio device after using a Wireless Testbench object that uses a custom prebuilt hardware image. For details, see Wireless Testbench Applications on NI USRP Radios.

Version History

Introduced in R2013b

R2024a: Support for N3xx series radio devices

You can now use the sdruload to load FPGA and firmware images for USRP N3xx series devices.

R2024a: Support for N3xx and X3xx series radio devices moved to Wireless Testbench

Support for NI USRP N3xx and X3xx series radio devices has moved from Communications Toolbox Support Package for USRP Radio to Wireless Testbench Support Package for NI USRP Radios.
