I need to be able to wake up a process every 100 us. I know that the
current version of QNX RTP onlyt support a minimum 500 us resulution on the
timers. On the current Single Board Computer we are currently using I
manage to achieve this by using the external RTC on the PCI bus that is
unique to this VME board. I have a interrrupt that is generated every 100
us that wakes up my process. The problem now, is I need to this on a new
SBC that does not have a external RTC. We need to change SBC since the new
project requires extended temperature range of operation and the curretn SBC
doesn’t support it.
Is there any plan to increase the timer resolution of the QNX kernal (RTP
6.1 and up) to at least 100 us in the near future?, this would permit us to
have more flexibilty in boards selection in the future, since it would
remove the dependency on this 100 us requirements from the board HW.
Thanks in Advances for any answers
