Hi,
At first, if nic_irq is not used by a RT_irq_handler, you do not need
rt_free_global.
Then after rt_request_global_irq , you have to do rt_enable_irq(nic_irq)
to enble it.
It should work correctly ...
The code appears correct unless the rt_enable_irq(irq).
Carefull if you use it on a SMP machine, cause the irq is get
simultanously on all CPU ! so
I use to attach the irq on one CPU against global to avoid multiple
instances.
Chris.
