Hello,
I'm trying to get the ethernet interface to work on a broadcom 97398
reference platform. Thanks to the linux-mips site I have successfully
built the cross compiler,built the linux-2.4.31-echostar kernel
source, and merged in the ethernet drivers from the tivo 8.3-linux-2.4
source tree.
I verified with Ethereal, the ethernet driver can send packets, but the
7038 acts as if interrupts are disabled. I verified that interrupt 23 is
enabled, but no interrupts occur. The uart and the ide/sata interface work
fine, so the MIPS int 2 is working fine. I know there is nothing wrong
with the ethernet interface because I use it to boot the kernel in CFE.
(see boot below)
suggestions?
Thanks,
-Scott
