[ixp1200] TFTPing problem in Linux

[cheewei]

Hallo,

My apologies first for asking a question not related to Vera. I am using SDK 2.01 on an IXP1240 (192.168.133.38) and trying to get the Linux kernel to boot up in Cygmon from a remote Linux tftp server (192.168.133.40). I am having the problem of Cygmon stuck at the message: TFTPing /tftpboot/zImage... the moment I issued a glinux command without returning a login prompt on the remote shell.
My config is as follows:
Local IP (192.168.133.40) 
Remote IP (192.168.133.38)
Linux kernel file name (zImage)
Linux ramdisk file name (ramdisk_img.gz)
Linux kernel load offset (C4008000)
sram size : 4k
dram size: 0x6FFF000
Upstream win:1M
Next, I tried out from Cygmon:
tftp 192.168.133.38 192.168.133.40 /tftpboot/ramdisk_img.gz 0xc1000000 but the same problem occurs. It stops at TFTPing /tftpboot/ramdisk_img.gz... 
In fact, I can ping to the target when this message appears and an "tftp unreachable" packet was also captured. I don't quite understand this because I am sure the TFTP
server is working correctly as I could get the file 'zImage' or 'ramdisk_img' that I want from the Linux server onto the WinNT (192.168.133.133) which is also hooked to the same subnet for the purpose of Workbench development by issuing a "tftp 192.168.133.38 GET /tftpboot/zImage". I am running the server on Linux 7.2. The TFTP's port is enabled and ipchain service is switched off. 
I appreciate if anyone could offer me a pointer or solution to that and how I could reach the stage of remote login prompt.

kind regards,
cheewei
