I captured some packets using ethereal and I see the request to the bootp server contains the wrong file name. The reply from the server matches the request.

Here is the output from U-boot in the 3 cases I described:

(1) Environment variable bootfile = zImage, try to load some other file:

u-boot> bootp 100000 10got.img BOOTP broadcast 1 DHCP client bound to address 192.168.0.43 TftpStart(zImage:192.168.0.1) TFTP from server 192.168.0.1; our IP address is 192.168.0.43 Filename 'zImage'. Load address: 0x100000 Loading: ################################################################# ################################################## done Bytes transferred = 585718 (8eff6 hex) u-boot>

(2) no bootfile env variable

u-boot> bootp 100000 10got.img BOOTP broadcast 1 DHCP client bound to address 192.168.0.43 TftpStart(no bootfile:192.168.0.1) *** Warning: no boot file name; using '2B00A8C0.img' TFTP from server 192.168.0.1; our IP address is 192.168.0.43 Filename '2B00A8C0.img'. Load address: 0x100000 Loading: * TFTP error: 'File not found' (1) Starting again

(3) tftpboot command

u-boot> tftpboot 100000 10got.img TftpStart(zImage:192.168.0.1) TFTP from server 192.168.0.1; our IP address is 192.168.0.44 Filename '10got.img'. Load address: 0x100000 Loading: # done Bytes transferred = 921 (399 hex) u-boot>

I'm using u-boot 1.0.0 on a xilinx embedded ppc 405 and I see the follow unexplained behavior:

if I do a bootp <address> <filename> it always bootp's the filename stored in environment variable bootfile rather than the filename I specify in the command line. If I have no bootfile env variable it tries to bootp a garbage file name.

What does the reply packet sent by your BOOTP server contain exactly?

Best regards,
