AW: netdemo on mvme 2600/712

Mon Jan 11 15:11:47 UTC 2010

Thanks for your quick reply.

I have checked my network settings and found that I did not enter a Gateway IP address. Now the netdemo application says "Network Initialized" on startup instead of "Network Unreachable". But the controller still seems to be dead under RTEMS and without an IP address. Until now I did not see any packet coming from the MVME2604 in Wireshark after RTEMS was started.

When I ran netdemo for the first time there was a simple message "pci: interrupt routing not available for this bsp". And indeed: In libbsp/powerpc/shared/motorola/motorola.c the interrupt routing table entry is NULL for the MVME2604/712. So I thought the error was hidden somewhere in this place and finally found your discussion from Oct. 2005. If I remember right, the output from my first post is actually from using the IRQ routing table mvme23xx_intmap for my board.

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?

This is not an IRQ routing issue.  The demos build for local host by 
default.
You need a network configuration that matches your local network.

See networkconfig-BSP.h for some that match the RTEMS lab. :)
