[Discuss-gnuradio] Latest uhd and e100 fpga image seemingly incompatible |

I copied usrp_e100_fpga.bin from the tarball here:
http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/ into /usr/share/uhd/images/ and rebooted several times (assuming the fpga image is reloaded on every boot, is this necessary?). When running benchmark_rx_rate I get the error "Error (usrp-e recv pirate loop): bad vrt header or invalid packet length" (See below for full runtime log).
I then tried to update manually,
address@hidden:/usr/local/share/uhd/usrp_e_utils# ./usrp-e-utility --fpga /usr/share/uhd/images/usrp_e100_fpga.bin
USRP-E Utility loading the FPGA...
Loading FPGA image: /usr/share/uhd/images/usrp_e100_fpga.bin... done = 1
Configuration complete.
Done!
and reboot but this resulted in the same issue. Any idea why the e100 fpga image is seemingly not compatible with the latest UHD? Thanks!
