My new board could boot now.

But i could not ping tftp server successfully when i want to replace my kernel by uboot tftp. i check rx+,rx-,tx+,tx- of rj45,their signals always exist. rx+ is a little volts higher than rx-.tx+ is also higher than tx-.and rx+ tx+ are around 3v .rx- tx- are between 3.3 and 2v.I think my net hardware is ok.But I could not connect to tftp server.I set parameter as below in uboot

setenv ipaddr 192.168.1.10

setenv serverip 192.168.1.100

setenv ethaddr XXXX

and then ping 192.168.1.100,failed.I tftp as below

tftp 0x80700000 uImage

uart0 shows

TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT

however,I could ping tftp server successfully by another PC,that is PC to PC.But my board could not.Why is it.

Any light would be appreciated.thank you very much.

You don't have tftpd configured correctly on 192.168.1.100 Please refer to

I am glad to see your answer and thank you.

OS of my tftp server is ubuntu 9.I install tftpd-hpa recommended by ubuntu.So i will follow you advice to test.But I have a question that is why i could not ping tftp server successfully.If PC ping tftp server,it is ok,no problem.If leopard board ping tftp server,it failed.Why is it?Thank you.

I follow your suggestion and setup tftp service again according to www.ridgerun.com/.../Setting_Up_A_Tftp_Service

Kevin,

I misread your first post.

> But i could not ping tftp server

I thought you could ping the tftp server, thus I thought the problem was with tftpd.

On leo365 in uboot, try

ping 192.168.1.103

where 192.168.1.103 is your ftp server.

If you don't get a ping response, then on the Ubuntu host, try

sudo arp -s 192.168.1.10 00:0C:0C:A0:02:b5

ping -c 5 192.168.1.10

My guess is address resolution protocol is working in both directions.

Hi Todd

thank you for your reply.i am appreciated.

I follow your advice.But ping also failed.

My RJ45 led blinks when host pings leopardboard.And my RJ45 led also blinks when leopardboard pings host.

When i connect my leopard board 's RJ45 to host's RJ45,the net icon of host changes from unconnected to establised.

rx+ rx- tx+ tx- of ksz8001l all have signal.

However,I could not ping successfully.Why?

Could you expert give me some light?

Could anyone give me some light?
