Another quick question. Since the Ethernet devices seem to both be working on the physical layer (we can detect the cable plugged in) it must be a software related problem. How does u-boot use the Ethernet chips, i.e. s to awhere does it get driver to actually perform ping and tftp commands? I know tsec.c there is phy_info data. Is this basically what u-boot uses as the dirvers?

Hey All,
We are working on a Freescale Development Board (the MPC8315E-RDB). We have used this board in the past with u-boot and it worked perfectly. However now that we are trying to use it again - we seem to be having some trouble getting the network working. We have tried the following with a number of u-boot.bin files (version 1.3.0 the latest 2009.03 version from the git repository, and a couple of more from Freescale). However we are having no luck.
We erased the flash on the board and every since then cannot get a ping reply from any deivce on our network, and we cannot ping the board itself.
Our set up is very simple we have: • Hub connecting all the devices • Server plugged in with light on (192.168.0.31) • TFTP server plugged in with the light on (192.168.0.22) • MY laptop plugged in with light on (192.168.0.202) • The Freescale board with light on (192.168.0.109) - thus it can detect the pressense of the board on the hub
When we try and ping with no cable plugged in we get the following:
=> ping 192.168.0.31 eTSEC1: No link. eTSEC0: No Link. Using eTSEC0 device ping failed; host 192.168.0.31 is not alive
When we try and ping with a cable plugged in we get the following:
=> ping 192.168.0.31 Speed: 100, full duplex Using eTSEC0 device ping failed; host 192.168.0.31 is not alive
Since all the lights on the hub are on we once again know that it is able to detect the presence of the cable on the board. Also since the board can detect the pressense of a cable it seems to be working, at least on the physical layer. Is there anything one must do to ensure that u-boot has network support? We have built editted versions as well us just extracting u-boot, building it and programming it. Nothing seems to be working.
