Hi, I'm missing something obvious and need someone to point me in the right direction.
I'm finishing up mapping IRQs on a CS5530 winterminal board I've got. I know the IRQ mappings of each on-board device and slot, and I put together my irq_tables.c accordingly. However, only the first 2 entries get written to the IRQ table, even though the file designates 3. Then, when I boot the LB image, I get this warning: Inconsistent IRQ routing table size (0x40/0x50)
The 0x50 makes sense; that's the "32+16*3" from my irq_tables.c. But where is the size being set to 0x40? It seems there's a configuration I missed somewhere. My irq_tables.c is below.
thanks, Jonathan
