Hey all, I've recently installed GNU Radio on a new computer. The program I've been running runs on every other system in the room, but this one throws a RunTimeError. It states "DDC software is too new for this hardware. Please downgrade to a driver that supports hardware revision 0." I've tried googling the issue, but it comes up with HVAC maintenance websites and what-not and there aren't really any other good resources for this error. Has anybody encountered this error before and what did you do to fix it? -- Thanks, Taylor

Dear Taylor, Please try to update your FPGA images by running the uhd_image_downloader to get the latest image that corresponds to the code base that you are running. Let us know if still face this issue after loading the latest version of the images. If you are using the X3X0 device, the procedure for loading the FPGA images is described here <https://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_load_fpga_imgs>.

Hey guys, I've used the uhd_images_downloader and the uhd_image_loader as per Nicolas's suggestion and altered the buffer size to 576,000 as Jose suggested. Neither of these attempts worked! The uhd_images_downloader installed 003.009.007-r onto the USRP. Is there any other way to change the DDC software or overcome this flag? See the attached image for the latest diagnostic screen shot.

 Dear Taylor,

 Please try to update your FPGA images by running the
 uhd_image_downloader to get the latest image that corresponds to the
 code base that you are running. Let us know if still face this issue
 after loading the latest version of the images. If you are using the
 X3X0 device, the procedure for loading the FPGA images is described
 here
 <https://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_load_fpga_imgs>.

 Regards,
 - Nicolas

Taylor, this error message means your UHD is from master branch. If your uhd_images_download is trying to install 3.9.7 images, the most likely explanation is that may you have an older version somewhere on your system -- the download URL is baked into the tool on installation. Here's what uhd_images_downloader --help looks like on my computer: ``` Usage: uhd_images_downloader [options] Options: -h, --help show this help message and exit -i INSTALL_LOCATION, --install-location=INSTALL_LOCATION Set custom install location for images [default=/home/mbr0wn/.usrlocal-uhd- master/share/uhd/images] --buffer-size=BUFFER_SIZE Set download buffer size [default=8192] -b BASE_URL, --base-url=BASE_URL Set base URL for images download location [default=http://files.ettus.com/binaries/images/] -f FILENAME, --filename=FILENAME Set images archive filename [default=uhd- images_3.11.0.git-227-g9277fc58.zip] -c CHECKSUM, --checksum=CHECKSUM Validate images archive against this checksum (blank to skip) [default=6fc29c5c141e8f3faec6189ab07e458d] -t CHECKSUM_TYPE, --checksum-type=CHECKSUM_TYPE Select checksum hash function (options: md5) [default=md5] -k, --keep Do not clear images directory before extracting new files [default=False] -v, --verbose Enable verbose output [default=False] --force-delete Delete all files in the target images directory without prompting [default=False] ``` Note the defaults for -f and -c. Do you see the same? One thing you can try is running uhd_images_downloader with -f and -c and copy the values from above. However, if it's an old tool it might also copy the downloaded files into the wrong location. But, one step at a time. -- M On 01/22/2018 01:31 PM, Taylor Eisman via USRP-users wrote: > Hey guys, > > I've used the uhd_images_downloader and the uhd_image_loader as per > Nicolas's suggestion and altered the buffer size to 576,000 as Jose > suggested.

Hey guys, So it turns out Martin was correct. I needed to install at least the 3.11 firmware update. Unfortunately, it seems that most of the sources only include 3.10 right now, which is why uhd_images_downloader/loader wasn't working. Thanks for all the help guys!!!!
