Re: [Gumstix-users] timer FIQ and CONFIG_FIQ

[ecrespin <eli...@gm...>]

Success: It works. Here is a FIQ timer for Overo (omap35xx) on 2.6.33.

All it does is toggle a gpio pin. It runs for hours without problems. If I
perform disk search or net access during execution, the timing does not
appear to be affected. 
Testing what happens to this fiq kernel module with high cpu load or high
memory usage, is still in the to do list.  Also I will experiment with more
complex functions within the timer calling other functions or Kernel APIs. 

@Dave, Thanks for the advice received. 

Improvement suggestions are welcome!
