These are the steps for upgrading an old USRP2’s SD card for the UHD driver:

  • Download, build and install GNU Radio using the build-gnuradio script.
  • Download pre-built FPGA and firmware images from http://files.ettus.com/uhd_releases/master_images/ (we only need usrp2_fpga.bin and usrp2_fw.bin
  • Install python-tk (required by usrp2_card_burner_gui.py)
  • Run sudo usrp2_card_burner_gui.py, choose the two .bin files above. It will automatically choose the correct device (/dev/mmcblk0)
  • The IP addresses should be: laptop: 192.168.10.1, usrp2: 192.168.10.2
