cannot ping serverip from u-boot.

[Mahesh Kurapati]

Hi all,

I am using openbmc-2.9.0 on AST2500 BMC.  From the u-boot, I could not ping to any external node be it on the same network, or a different network.  I configured static ip 192.168.0.81 for my laptop and attached wireshark to the same interface.  I don't see any ARP requests when I issued ping command from BMC to the laptop.  I see that link status is up from the debug prints, and also the MDIO status registers.  Don't see anything wrong.  Not sure what/where to look for to debug the issue further.  Appreciate any suggestions.  We are using Marvel Alaska 88 series Phy.  If this works, I want to tftpboot the board, and flash the eMMC.  That is my goal.
