816x EVM TFTP boot not working

CB.

Trying to boot over TFTP, but comes up with the  "Loading: WARN: emac_send_packet: No link   " when it should

receive the file from the host pc. I have found other users with similar problems, but found no solution.

I can ping the EVM board from another host pc, and I can also use the TFTP server from a windows pc, and download

the same file. So the connection should be good, and the file can be downloaded.

Have also tried to manually enter the commands on u-boot command line, like hdcp, ping and tftpboot.

Have also tried with other binary files, same result. Fixed IP config does not help.

Any ideas ?

Which PSP release are you using?

Can you provide the packet capture logs by connecting the EVM to PC via cross cable.

Casper,

Did you try pinging from the target board to some other machine? does that work?

Looking from the uboot log the emac is detected and initialized.

If ping works from your target board, there should be some issue with tftp server settings.

Hi Mugunthan

I am trying to get the image with the PSP 04.00.01.13 release.

I have tried capturing the packets with wireshark, but not with a crossed cable, it goes through a switch.

I have captured two pcap files (attached), one with capture where i start the tftpboot with the "boot" command in u-boot. And one capture when i am downloading the file from another pc with success. It is clear from the packet capture, that the TFTP start commands does not work, it looks like the port number is not correct for the initialization of the tftp get sequence. Also it looks like it slowly gets the file over (parts from the file looks good), but then halts for several seconds, and intitally stops trying, restart the ARP broadcasting. It will loop like that forever.

I have removed most of the packets from the pcpap file tftp_good_pc to keep the file small.

Yes, ping works fine from both sides. And the TFTP server works as intended, as i can download the same file from another machine with TFTP get.

Hi Casper,

Any updates? I encounted similar issues.

My DM8168EVM can not tftp when using tftpd64 on windows PC, but tftp works well on Virtual machince(Ubuntu with tftpd-hpa)

From tftpd64's log, i can see the request from board, but no transfer is established.

Thanks,

Eason
