Latest uhd and e100 fpga image seemingly incompatible

I completed building and installing uhd and gnuradio on an e100 last
night
following the directions here:
http://code.ettus.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ

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,

–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

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!

Actually, it should be rejecting the image you loaded because it needs
compat 0x3 and that image is 0x2. You sure the latest UHD in installed?

The most recent image for the current master isnt in a package:
see usrp_e100_fpga_compat3_feb_25.bin in
http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/
