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
