Subject: Missing some interrupts
Date: Sat, 6 Jun 2009 06:17:42 -0700 (PDT) [thread overview]
Message-ID: <23901807.post@talk.nabble.com> (raw)
Hi All,
i have a freescale board, that contains MPC8555 processor & DSP-core
there is a GPIO connecting the DSP-core into an input pin of the OpenPIC of
the MPC8555 processor.
i test one interrupt from the DSP-core to the MPC8555 processor where i
configure this interrupt line to be edge-triggered (falling edge) & i
receive it successfully
but
when i generate this interrupt 10 successive times using for loop
i just receive 2 interrupts?
why can't i receive the 8 other interrupts?
i print the value of every irq number inside do_IRQ & i found that i receive
the DSP-interrupt just only twice.
do u have any suggestions to solve this problem?
i want to make sure that i can receive 10 interrupts
