Hello Jonathon, Thank you for your suggestion. I don't really care which UHD version I am using. I was looking for the shortest path to an FPGA image that already has the replay block implemented so that I don't have to rebuild the FPGA image. Can you suggest where I might find an FPGA image for E320 that already has the replay block? Or was it not implemented at all in any image? I vaguely remember looking at the history of the FPGA files of the E320 a few months ago and I think it appeared in one of the previous versions of the FPGA images and it was then replaced with FIFO.
If no FPGA image for the E320 exists with the replay block what UHD version would you recommend as most stable? I am currently working with UHD 3.15 on an array of E310 units without any problems. Would you suggest going to 4.1?
