[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
