SAMA5D3 degraded throughput of EMAC

Thu May 15, 2014 7:21 pm

Hi All!
I am using SAMA5D36 xplained board having one GMAC and one EMAC. I am getting very degraded performance with its EMAC (GMAC is apparently working fine). My application involves more than 4Mbps data transfer rate via EMAC which seems practically impossible with the provided code. I have configured it in loop back mode and sending UDP burst for test purpose. Same code on AT91SAM9260 is giving much better performance. Is there some bug in the code/board? Has any one else experienced the same?
