Ethernet Connection Issue with LAN9221 Controller.

Other Parts Discussed in Thread: AM3703

Hello,

I have a custom AM3703 board which was designed after the EVM3530.  I am using CE7/VS2008/Adeneo BSP.  I have a problem with my board hanging during the boot if I have the Ethernet cable connected to the board.  This problem happens either booting from Flash or through KITL.  If I power up the board with the Ethernet cable disconnected, It can boot all the way in and execute my application as seen the attached debug output (fromMyBoard.txt).  However, I can not debug my application without the Ethernet connection.  The EVM3530 works fine booting from Flash with the Ethernet cable connected(fromEVM.txt).

I have the Catalog configured similarly to the EVM, with NDIS SMSC driver included.  Our board uses LAN9221 Controller and the EVM uses LAN9220.  However, the BSP appears to support both since the file "smsc9118.c" allows the detection of LAN9221.  I am not sure what is the cause of the problem.  I appreciate your giving some pointers on how to debug it.

Thanks,

Luan
