-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Clock rate recovery - unbricking
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-It is possible to set a clock rate such that the UHD can no longer communicate with the FPGA.
-When this occurs, it is necessary to use the usrp-e-utility to recover the clock generator.
-The recovery utility works by loading a special pass-through FPGA image so the computer
-can talk directly to the clock generator over a SPI interface.
-
-Run the following commands to restore the clock generator to a usable state:
-::
-
- cd <install-path>/share/uhd/usrp_e_utilities
- ./usrp-e-utility --fpga=../images/usrp_e100_pt_fpga.bin --reclk
