NiosII alt_irt_handler 死锁的问题??

在用NIOSII 调试 FreeRTOS的时候发现进不了main 函数,直接在 alt_irq_handler 函数中死锁,

在 altera 中是这么解释的

问题

Why does my Nios® II application deadlock in the alt_irq_handler() function?

解决方案
The alt_irq_handler() function can deadlock if the hardware peripheral deasserts its irq prior to alt_irq_handler() reading the ipending register. The hardware peripheral should ensure that the irq is active until software takes action to clear the irq.

不知是什么问题导致的...
