[USRP-users] tlast signal in CHDR

2021-04-15 Thread xiapeiqing
I am working on some existing code of RfNoC on UHD_3.15.0 to process the incoming rx data stream. The CHDR wrapper/unwrapper makes use of the TLAST signal. For a stream of continuous ADC samples, there is no obvious data block boundary such as each line/frame commonly in video. I didn’t study t

I had problem talking to my x310 device over ethernet. Does anybody have similar experience? The following external hardware are used to test my x310 units: * host PC with 10G intel NIC * 192.168.10.1 static IP, connect to X310 port0 using SFP adaptor & CAT-6 cable * 192.168.40.1 static I

Hi, Marcus, Thanks for your reply. The clear & precise problem description is an endless pursuit I should try to do better. My experience is a lot of problem get answered by itself when it is described clear enough to the very detail, it’s part of a learning process. My current guess is the FP
