Hi Adam,
Sorry for the late respond as I miss out your feedback in early Aug.
Thanks for the clarification on SST vs MST log is due to different monitor.
- In this case, I would categorize them as different hardware setup as the transceiver channel performance on SST monitor maybe difference than MST monitor
Is your MST monitor = Asus PQ321Q ?
- One thing that I want to clarify with you is you are not using typical MST test setup where we are either using MST hub or MST daisy chain monitor
- So, I am not sure exactly how your MST monitor works
- Would you be able to perform MST daisy chain monitor testing at your side ?
As for the Aux log debug,
- You can enable Aug log traffic monitor via BITEC_AUX_DEBUG parameter in Bitec software config.h. But we typically do this for Intel FPGA DP RX, I am not sure whether we can do it for DP Tx as in your use case or not
- Assume it works, then you just need to open NIOS II shell while programming DP design into FPGA then it will auto capture all the AUX log traffic in NIOS II shell terminal
- Then you can help me to capture the raw Aux log for both SST and MST monitor
- The challenging part will be hard to decode the raw Aux log
- Assume we are dealing with signal integrity issue here, easiest way will be to try out different brand DP cable, preferable shorter cable to improve the signal quality.
Thanks.
