Josh:

Correction:  I downloaded the tested your second build:
http://files.ettus.com/binaries/e100-misc/usrp_e100_fpga_v2_timing.bin

not the first one:

http://files.ettus.com/binaries/e100-misc/usrp_e100_fpga_v2.bin

Josh:

I am having the same problem as Ken with the "S"s while transmitting from the USRP-E110.  I thought I would get your latest FPGA fix a try downloading usrp_e100_fpga_v2.bin to /usr/local/share/uhd/images, saving the original E110 bin file, and renaming it to usrp_e110_fpga.bin. I thought that would be too easy to fix the problem and it didn't. I got the following error:

linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500; UHD_003.005.001-25-ge134b863 Creating the usrp device with: ...
-- Loading FPGA image: /usr/local/share/uhd/images/usrp_e110_fpga.bin... done = 1
ERROR: EnvironentError: OSError: INIT_B went high, error occurred.


I am guessing that there are some differences in the FPGA builds between the E100 and E110.  Do you have a version with the fixes for the E110???

Hi Josh,

I replaced the file and the problem still remained.  However, it seemed to take a bit longer before the sequence errors kicked in.

Thanks,
Ken
