Hi Dan (and all), I've been playing w/ mmap for flash and nvram access on the rpxlite(MV derived kernel). One thing I've noticed is that it won't let me mmap the top 1MB of the address space. I'm guessing that the region isn't represented in the MMU stuff or this is a deliberate block in the /dev/mem driver.
I've done a little digging on my own and haven't found the cause. Can anyone point me to the right file/function(s)? Many Thanks, -Mark Mark S.
