       i‘m using p2020rdb-pc for some telecommunication application . after i booted my system success from eTsec1 (etsec2,etsec3 also can do) by tftp. i tried to test the function to make sure every ethernet works nomally.  and found out that i couldn't figure out a solution to send dates from one ethernet to another . i used ping to connect to the board IP (the env variable i set in the u-boot). but just couldn't get through . did i got something wrong with my method? and i‘ll appropriate it if someone can tell me how can i test the Ethernet on the board ? the Documents in the ltib tend to test the Ethernet with smartbits ,so how can do the same job without smartbits ?

     i’m looking forward to your help ,thank you .

See below technical support comment:

Please note that U-Boot uses a polling for networking (not interrupts) - if you have not run a command, it will not respond to any packets.

Ping from U-Boot to a host should work. Ping from a host to U-Boot should not.
