mmap not working for Athena III board
I have tried to mmap Advantech's PCM3680 CAN board I/O space into memory on the Diamond Athena III board until I am
blue in the face (no, seriously, BLUE! It's not pretty). There are no resource conflicts that I can ascertain - no
conflicting irqs or bae addresses. I am using QNX 6.4.1. The odd thing is: I can address the Advantech board just fine
, using the same software and OS, on an older Pentium M CPU. Does anyone know of any "gotchas" for the Athena II/III?
That is, dos the ISA bus require some setup I don't know about or something else? Thanks for any advice!
