I would like to give some more information about my problem. u-boot's tftp transfers do eventually complete and the evm boots. I can then execute tftp get commands from Linux on the evm and these execute quickly. So the problem definitely has to do with the way u-boot uses tftp.

Hi
I am using an Advantech TMX320TCI6614 EVM to develop code for an ARM core on a TI C66x device. The ARM core runs:
U-Boot 2011.06-00002-gc4611c1-dirty (May 30 2012 - 15:38:01)
I have booted this target card for several months from a tftp server running under Ubuntu 10.04, with no problems. But, this week, I have tried to move to a tftp server that runs on a different machine running Ubuntu 12.04 LTS.
Since moving to Ubuntu 12.04 the tftp download is very slow, although it does succeed eventually. I have tried getting the boot files using a tftp client running on another Ubuntu host and the download is fast.
Please can anyone suggest a reason for the slow download when using the EVM with the 12.04 server?
Best regards
David
