I didn’t, unfortunately. I could get each board to work individually, but could not get them to work together.
I had better success with getting feedback from an Arduino board out on LinkedIn - you’re welcome to see if the thread responses I got there offer you anything illuminating. Basic response was to use a board with the SD shield and the Ethernet already built on… Also, one other respondent suggested they had not had a lot of luck with SEEEDStudio stuff.
