netdemo on mvme 2600/712

Hello all,

I am new to RTEMS. Currently my goal is to run EPICS 3.14.11 with RTEMS 4.9.2 on a MVME2604 / 712 target. Until now it seems like everything but the network works fine under RTEMS. So I tried to run the netdemo example and see what's wrong here.

There was discussion about the RTEMS netdemo four years ago between Till Straumann and Joel Sherrill, where a solution for a similar board was briefly discussed: a missing IRQ routing table for the target board:

It seems like this is also my problem. For RTEMS there is no IRQ routing table for the Mvme2604/712 in the motorola powerpc bsp. I tried to use the MVME2600/761 table for my board without success (see below). Has anyone successfully run the netdemo for the MVME2604/712 and can help me with this problem?

Best regards,

Thorsten Frunzke
