EVMK2H PCIE legay Interrupt

Charis Lee
Intellectual 340 points

Experts advise the following questions:

1.I set EVMK2H to PCIe boot mode and the PC(win7)can enumerate the PCIe at EVMK2H

2. I check register MSI_CAP,MSI_EN bit in MSI_CAP is set to 1(MSI_CAP :0x00817005)

LEGACY_A_IRQ_ENABLE_SET; LEGACY_B_IRQ_ENABLE_SET; LEGACY_C_IRQ_ENABLE_SET; LEGACY_D_IRQ_ENABLE_SET are all be set to 1;

3. I set EP_IRQ_SET to 1 to Generate an interrupt as below
(*(unsigned int*)0x21800064)=0x1;

But at PC (win7)side: Windriver can not receive interrupts,please give me some advice to solve the problem,thanks!
