u-boot hangs at AM3517EVM with PSP03.00.01.06

I am using AM3517EVM with PSP03.00.01.06 package.  Both x-loader and u-boot are configured with default

configurations.  The board boots to u-boot console normally.  Then I can ping to other PCs from u-boot.

However, after 30-60 minutes idle state of u-boot, I try to use 'ping' again.  The board hangs at 'ping' command.

Is there time out setting in u-boot code for ethernet?
