Thanks for the suggestions Wade. I will first try the low-hanging fruit of using the 300MHz DRAM clock. Fingers crossed! Rob On Thu, Feb 24, 2022 at 6:43 PM Wade Fife wrote: > Hi Rob, > > RFNoC doesn't support generating user clocks for you yet (the range value > is not currently used). You cou

Hi Rob, RFNoC doesn't support generating user clocks for you yet (the range value is not currently used). You could use the `dram` clock on N310 and connect that to the `ce` inputs of your blocks. That should be about 300 MHz. The `rfnoc_chdr` clock is 200 MHz on N310. If it won't close timing wi

Hi Maria, I'm glad that things are working well now. I don't really understand what the problem was (possibly related to MTU forwarding policy that defaults to DROP in your UHD version and thus must be explicitly set to one-to-one in your custom controller). Good luck. Rob On Thu, Feb 24, 2022 at

Hi Rob, Good news! I managed to get my block receiving samples through the RX radio. It turned out to be a problem with the Radio and Streamer SPP configuration. If I set them with 256, it works. I can increase the number of SPP if I add a fosphor block instead of the QT sink (test it up to 1024).
