Thanks Brian, that seemed to be the trick, at least for the initial flowgraph I was trying to use (I think I must have missed a block in my second flowgraph). Sadly, I can only run it once and then it doesn't work on the second run, so I need to investigate that next. I feel like I remember so

I know this is an older thread, but I too am struggling to bring a block that someone else designed for us in 2015.4 to work in 2017.4. I dug around but I don't see any of our custom blocks using clear_tx_seqnum in their sub-modules or their config registers. They do use the config registers qu

Hi EJ, Sorry for the delay here. From the FPGA's perspective if you have something streaming between one set of blocks and then you start streaming a different application on another set of previously unused blocks, then the current clear implementation should still work as long as the new applica

Hi Brian, I finally got a chance to look at that change in a bit more detail. I need to test out this theory out but we may have added a regression with the throttle commit I pointed out earlier. The issue would apply to "sink" blocks only. We assert the clear_tx_seqnum signal when the block is in

I had some blocks that worked just fine with the old rfnoc-devel branch using 2015.4, but when this latest change to 2017.4 came in, my blocks stopped working. I've found that a significant change was how clear_tx_seqnum seems to now work. I've noticed that clear_tx_seqnum will be set while setti
