T4240 endpoint problem

[emilviding]

Hi,

I have a T4240 processor with PCIe1 configured as endpoint (HOST_AGT_PEX = 010).

The endpoint is connected to a PCIe switch. The Root Complex is a P1022.

I can't make any configuration accesses towards the T4240 EP, all I can see in my Lauterbach window is ????????. When I disable the controller in the DEVDISR register I read all ones.

Is there anything I need to do for the enpoint to answer configuration accesses? I have used P1022 and P4080 before and then you just have to turn the power on.

Regards,

Please check that CONFIG[CFG_READY] is set.

Well this is embarrassing... That solved it, thanks!
