您好!

yoctol kernel 4.1.15 + ubuntu 16.04 & android6.0 m6.0.1_2.0.0-ga 都有一樣的問題

HW:IMX6DL+AR8031

使用iperf -s 在測試

1:giga lan ,測試結果不到5Mbits/sec

2:10/100 就能達到 90 Mbits/sec 左右

是否有任何的修正檔可以協助,謝謝

謝謝 igorpadykov 回應

Boundary Devices的方式試過,結果一樣

相同的ethernet code ,在其他專案的板子是OK
在7專案板子,惟一的專案ethernet giga的速度 test fail

此專案在去年年底才進行,HW上是跟其他專案一樣的線路

第一板HW 就發生 giga lan test fail

經過改板,將imx6dl 到ar8031 距離縮短,結果一樣test giga lan fail
是否除Boundary Devices的方式之外的解決方案,請求協助,謝謝
