Is this a standalone snippet or is it running inside an OS? Is the MMU
enabled? Are you running out of 32-bit RAM, with cache enabled?
Hi Iarwe,
It's a userland prog under a flavour of Linux (OSELAS), about which I
still learning (fast!).
I assume the MMU is enabled, and the prog is indeed in RAM. Don't know
about the cache (yet).
Thanks for the clues!
