Sorry for asking again, but my question form June 7. wasn´t answered and I am
not able to work it out by my own:
When I use a PPC-Kernel 2.4.25 with Xenomai 2.5.6 I get the message
"Xenomai: mmap local sem heap: No such device or address" when I start the
latency test (and other programs).
But the rtheap-Device exists (see below). Can anybody give me a short hint in
which direction to search.
Is Xenomai 2.5.6 intend to work with Kernel 2.4. ?
Thank you in advance
Roderik
