Hi Dmitry
I am sorry that I am not good at English.I do not know the
meaning of this sentence “but
can't it happen that both irqworks will be scheduled?”.I just explain what I
thought about irq handler about cc2420.I hope it may help.
cc2420 have not irq status register or something like that.It uses pin value
to indicate a successful transmitting or receiving package.A falling edge of
SFD pin means a successful
transmitting package. A raising edge of FIFOP pin indicates a successful
receiving package meaning while the SFD pin is falling.It means,during
receiving package, it will trigger two irqs.I found that SFD interrupt is
trigger first then FIFOP's.So, iI think both irqwoks will be scheduled.
Regards
liuxue

BTW: It seems the driver has some issues with IRQ enabling/disabling
(at least it looks so).
You have one multiplexed ISR, which then disables itself, enabling
happens in irqworks, but
can't it happen that both irqworks will be scheduled?
Could you please look into it?
