That makes sense. When I did the port I had a 6750 and 680. They are very similar but Force is too stupid to provide a method to uniquely identify a board at runtime. So, you see the kludge where anything booting a pcore kernel that has an MPC106 is a 6750 and if it has a MPC107 then it must be a 680. > Do you know where can i find documentation to solve this problem? > and where I have to modify? Talk to Force. You need the 3750 manual. I suspect that it has different interrupt routing than the 6750. Right now, you are picking up the pcore_6750_map_irq table which has irq 10 for the on-board tulip. More than likely it's routed to a different input on the 3750. You would create a pcore_3750_map_irq, and provide some way to uniquely identify that you are on a 3750 and have the kernel use that map_irq function. > here you can find the bios log, maybe you can find an answer. > http://lsa1pc32.epfl.ch/~gamba/robox/ Definitely looks like pci interrupt routing is incorrect. tulip driver isn't getting interrupts. One warning, once you get 3750 docs...don't trust them, they are often incorrect. :) When you get this working, please post a patch so it can be incorporated. Good luck.
