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.

If I use tftpboot <address> <filename> it gets the file name on the cmd 
line.

I don't think this is expected behavior.  Is that incorrect?  Any ideas 
what I'm doing wrong?

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

Best regards,

A bit more info --
it looks like the correct file name is sent in the dhcp request,
but then u-boot switches to tftp mode with the incorrect file name in 
the request.
I have placed the capture file here:
http://www.lambdaaccess.com/u-boot.libpcap

thanks again for your help.

[U-Boot-Users] bootp

[ppc user]

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)
