Hi all,
I face a issue on AM3351 + IP101GR (Etherne PHY) can not ping in U-Boot.
H/W is customer's board use RMII for Ethernet, SDK version is Processor SDK 1.0.0.3.
I follow the China E2E thread to setup RMII as following link:
www.deyisupport.com/.../45981.aspx
At the first time, my boot-up log always show up "Phy not found".
After I setup the configuration as the link, this log is not show up anymore, I think the phy is working fine.
However, I use ping command to ping the Gateway, it always show up the address is not alive.
Then I use Wireshark to analysis the packages while use ping command.
I find out the TX of customer's board looks like OK and PC's feedback is OK too.
But it seems customer's board can't recognize the feedback form PC and did not replay it.
(Please see the attachment image)
Is there any suggestion for this?
Best Regards,
Wayne Kuo
