A USRP1 can be identified though its 8 digit serial number,

The device address string representation for a USRP1 with serial 12345678:

    serial=12345678

Change the serial number

The USRP1 serial number can be changed to any 8 byte string. Examples:

::

    cd <prefix>/share/uhd/utils

    ./usrp1_serial_burner --new=87654321

    -- OR --

    ./usrp1_serial_burner --new=Beatrice

    -- OR --

    ./usrp1_serial_burner --old=12345678 --new=87654321

Specify a non-standard image

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The standard USRP1 images installer comes with two FPGA images:

 * **usrp1_fpga.rbf:** 2 DDCs + 2 DUCs

 * **usrp1_fpga_4rx.rbf:** 4 DDCs + 0 DUCs

By default, the USRP1 uses the FPGA image with 2 DDCs and 2 DUCs.

However, a device address parameter can be used to override

the FPGA image selection to use an alternate or a custom FPGA image.

See the images application notes for installing custom images.

Example device address string representations to specify non-standard firmware and/or FPGA images:

::

    fpga=usrp1_fpga_4rx.rbf

    -- OR --

    fw=usrp1_fw_custom.ihx

    -- OR --

    fpga=usrp1_fpga_4rx.rbf, fw=usrp1_fw_custom.ihx
