[gPXE-devel] Attempting to add support for Broadcom BCM5755M (14e4:1673) ethernet adapter

[Quinn Plattel]

Hi,

I am currently testing his code now, but I currently have compile issues
when I try to turn on debugging.
Regarding iSCSI - i have a fair bit of experience there.  I have a
gpxe/pxe/tftpboot/iscsi implementation currently working with Ubuntu.
Check out etherboot.org for my iscsi recipe. :-)

Do you happen to know why I get this error:

$ make bin/tg3_main.usb DEBUG=tg3_main:3,tg3_hw,tg3_phy
  [BUILD] bin/usbdisk.o
  [OBJCOPY] bin/usbdisk.bin
make: *** No rule to make target `bin/tg3_main.dbg3.o', needed by
`bin/blib.a'. Stop.


br,
Quinn
