From the code I think it should work. Ok. Example (from real life): After power on I have loadaddr=0x100000 serial#=69383 ethaddr=00:A0:33:01:07:0F A bootp results in: => bootp FEC ETHERNET configured BOOTP broadcast 1 DHCP client bound to address 10.0.9.161 ARP broadcast 1 TFTP from server 10.0.2.9; our IP address is 10.0.9.161 Filename 'pImage.DAB4K2'. Load address: 0x100000 Loading: ################################################################# ################################################################# ######## done Bytes transferred = 702439 (ab7e7 hex) => printenv loadaddr=0x100000 serial#=69383 ethaddr=00:A0:33:01:07:0F bootfile=pImage.DAB4K2 filesize=ab7e7 netmask=255.255.0.0 hostname=dab4k2_69383 rootpath=/opt/ELDK/ppc_8xx ipaddr=10.0.9.161 serverip=10.0.2.9 Fair enough! But let's do it again... => setenv autoload n => bootp FEC ETHERNET configured BOOTP broadcast 1 DHCP client bound to address 10.0.9.161 => printenv loadaddr=0x100000 serial#=69383 ethaddr=00:A0:33:01:07:0F autoload=n bootfile=pImage.DAB4K2 You see!? Only "bootfile" gets set. So a following tftp brings => tftp 100000 pImage.DAB4K2 FEC ETHERNET configured *** ERROR: `serverip' not set So I think BootpCopyNetParams() should get called regardless of autoload! Steven
