Hi Emeric, Thanks for replying. It is sad that this issue was not resolved. At least I know now there is a workaround by connecting external USB-ethernet. Chyifeng On Thursday, July 12, 2012 12:26:32 PM UTC-7, m-ric wrote: > > Hi, > > I run AOSP-4.0.4 on a pandaboard rev A3. I got linux kernel

Hi Enzeneer, No, it is different issue. The link you mentioned is related to SATA and SMP. I tried single CPU and nothing changes. It has not SATA either. So far I can only say that TX DMA is not triggered in this case. Moving USB mouse helps increasing TX data rate. Thanks for trying. Chyifeng

Hi all, I wonder if you guys have solution for it already? If so, please post it. I ran AOSP Android 4.3_r2.1 on pandaboard ES rev B2 and it has similar problem. I got 10KB/s for TX. RX is ok, which is around 10MB/s. The kernel is Linux version 3.0.31-gcb5fc50 (*j...@jqueru.mtv.corp.google.com*)
