i.MX6 PCIe exclusive access control.

[satoshishimoda]

Hi community,

Out partner have a question about i.MX6 PCIe controller.

They want to know whether i.MX6 PCIe controller have exclusive management.

e.g. Wait access from CPU when i.MX6 PCIe is accessing to external PCIe device.

I looked for the management function in reference manual, but I was not able to find it.

So I guess the function is not implemented in i.MX6 PCIe contoller, is this correct?

Best Regards,

Satoshi Shimoda

Hi Satoshi

you are right, there is no special management function from

core in regard to PCIe module. CPU just can access PCIe registers

through NIC301 arbiter as shown in Figure 45-1. NIC-301 Bus System

Best regards
