AM335x NMI使用问题



Hi team

祝好!

客户咨询一个问题:

linux-3.2-psp04.06.00.07.sdk 版本下,AM335x NMI使用方法,
request_threaded_irq(7,NULL,xxx_int_callback,
IRQF_DISABLED | IRQF_NO_SUSPEND ,
"nmi_int",pdev);
irq_set_irq_type(IRQ_NNMI_NUM, IRQ_TYPE_EDGE_FALLING);
当前现象,反复触发,中断有时不响应;回调函数是否需要重置中断, 麻烦帮忙谢谢。

Best regards
Aosker
