<br>
I am attempting to add support to gpxe the Broadcom BCM5755M (14e4:1673)<br>
ethernet adapter.<br>
I have confirmed that the adapter works under linux with kernel 2.6.32.<br>
Here is some of my attempts:<br>
<br>
I first identified the pci vendor and device id via linux's "lspci
-n"<br>
command which gave me 14e4:1673<br>
I then added it to tg3.c file:<br>

This enabled gpxe to attempt to initialize the adapter instead of ignoring<br>
it. But it gives this error so far:<br>

added the following to tg3.c to identify the phy id:<br>

Unfortunately, this is as far as a i got. The error messages is still the<br>
same. I haven't been able to figure out what to do next. I have
tried to<br>
enable debugging by "make DEBUG=tg3" and also enabling the serial
console in<br>
<br>
console.h but the I just get a bunch of "?" instead of proper strings
on the<br>
serial port and I did configure my terminal emulator to 9600n81. Any
clues<br>
there? The terminal works fine with picocom under linux with the same<br>
serial settings.<br>
<br>
I feel I am so close in getting this card to work because the tg3 code is<br>
there but it just needs to identify and use the hardware. Just so you
know<br>
I have also downloaded the latest git release, but unfortunately, there is<br>
no support for BCM5755M yet.<br>
I found this page<br>
<a href="http://www.broadcom.com/support/ethernet_nic/determine_driver.php">http://www.broadcom.com/support/ethernet_nic/determine_driver.php</a>
which<br>
helped me identify the adapter as a model type NetXtreme Desktop/Mobile<br>
adapter. There is already support in gpxe for that type adapter such as
the<br>
BCM5751M.<br>
<br>
Any suggestions?<br>
