Subject: [Xenomai] Set gpio irq priority with tzic_set_irq_prio(int irq, int hi)
Date: Sat, 8 Jun 2013 23:40:54 +0800 (CST) [thread overview]
Message-ID: <44b485fd.1ee68.13f24728cbf.Coremail.ericvic@163.com> (raw)
Now I use Imx53 gpio2-14 to be a interrupt source ,but I found its priority so lower .
So I use tzic_set_irq_prio(int irq, int hi)
.................................
.............................
MY_GPIO2_14=(1*32+14)+128;
irq=irq_ to_gpio( MY_GPIO2_14);
mxc_tzic_init_irq(IMX53_TZIC_BASE_ADDR);
tzic_set_irq_prio(irq,20);//chang the priority to #30
.................................
......................................
Is it right？
