Hello, I am currently running into buffer overflows with the x410 where I am unable to stream for data rates larger than \~0.32 Gb/s when the CHDR_W is 128. However, if I stream using a CHDR_W of 64, I am able to push the data rate much higher(at least 3.2 Gb/s). I compiled a custom image using X4_400
My current set up transmits data over 1 SFP port, which is rated for 10 Gb/s. I guess is that since technically this port cant sustain the data rate of 500 MS/s(equal to 16 Gb/s), there could be at least 1 buffer than can not sustain the given data rate, even if I am not sampling continuously. \ I tried increasing the endpoint buffer sizes (REQ_BUFF_SIZE_EP) as well as increasing the buffer size set by the host computer, but both seem to have no impact on solving this buffer overflow issue. I saw a hard coded value in the x4xx.v where BYTE_MTU was set to clog(8192). Do I need to increase this buffer size as well? Thanks Joe
