Hi,
We got the correct value of CLK9 and CLK10. We found out a bug in the
function fcc_enet_open(). Our setting was CONFIG_USE_MDIO. In this mode,
the board is able to get packets from out side, but was unable to send
packets.
Now we changed the code like this.
fep->link = 1;
netif_start_queue(dev);
mii_do_cmd(dev, phy_cmd_config); /* display configuration
*/
return 0;
Originally the code was ( Line no 2174)
netif_start_queue(dev);
return 0; /* Success */
Now the ethernet works perfectly.
BTW, is there any tool/test case available to test the ethernet driver for
a long period of time?
Thanks

This is not correct. The ELDK does not do this. The ELDK is not a
Linux source tree.
Also, this setting is hardware dependent and differs from board to
board.

Then probably other changes / initializations (port pin
configurations) are needed as well.

This idepends on your hardware. Study the schematics.

Compare U-Boot code and other board definitions.

A secure program has to be robust: it must be able to deal with
conditions that "can't happen", whether user input, program error or
library/etc. This is basic damage control. Buffer overflow errors
have nothing to do with security, but everything with stupidity.
