bootp
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:

(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)

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,
