PCIe 中断问题



请TI工程师帮忙解答:

 我们的xtcievmk2x 开发板设置为PCIe boot 模式(EP),上电后发现Legay中断和MSI中断都被使能了,

MSI_CAP寄存器地址0x21801050的值为0x00817005

MSI0_IRQ_ENABLE_SET寄存器地址0x21800108的值为0x1

LEGACY_A_IRQ_ENABLE_SET寄存器地址0x21800188的值为0x1

LEGACY_B_IRQ_ENABLE_SET寄存器地址0x21800198的值为0x1

LEGACY_C_IRQ_ENABLE_SET寄存器地址0x218001A8的值为0x1

LEGACY_D_IRQ_ENABLE_SET寄存器地址0x218001B8的值为0x1

结果两种中断都不能触发。有什么方法可以设置为只使能一种中断吗?
