2018-07-12 Thread Rob Kossler
Hi Martin, Regarding the API version "guarantee", I am wondering if there is any way to distinguish between versions. Presently, it seems that branches 3.12 and master both have UHD_VERSION set to 3120099. I had previously been using UHD_VERSION to select (via #if) code appropriate to a given

Hi Mike, Martin and Marcus, I'll argue that from a mile high that changing MCR at runtime of a GR flow graph is an *extreme* corner case: It de-facto requires teardown of the UHD streamer, right (when else would you need it)? And that really doesn't fit all too nicely with GNU Radio's streaming

Hi all, I'm not sure this thread is going in a way that'll help John. John, let me try and rephrase the comments, and add my own: - First, we recently merged all of rfnoc-devel into master, and won't be updating rfnoc-devel any more. However, this is just an FYI and unrelated to any of your

Just to close this issue. We have several custom blocks in RFNOC. After upgrading Vivado we were able to build the image using new source code and had no issues. The problem was that our images were built with incorrect version. In source code, where do you find the version number of the UHD

Hi, It could be that calls to set_ampl() and set_freq() are made before analog_sig_source_x_1 is declared. Try moving the signal source declarations to the top of the # Blocks section. Cheers, Ernest On Thu, Jul 12, 2018 at 12:14 AM, Sims, William Herb (MSFC-EV41) < herb.s...@nasa.gov> wrote:
