I am using the TCI6638K2K keystone EVM and am having trouble enumerating a PCIe device. I am using MCSDK 3.00.03.15. I am trying to use the internal DSP loopback example as part of the PDK (PDK_base/packages/exampleProjects/PCIE_K2KC66BiosExampleProject). I have compiles this project and loaded it onto DSP core 0. When I run it I see this:
**********************************************
* PCIe Test Start *
* EP mode *
**********************************************
Version #: 0x02000004; string PCIE LLD Revision: 02.00.00.04:Nov 24 2013:17:35:53
Power domain is already enabled. You probably re-ran without device reset (which is OK)
PCIe Power Up.
PLL configured.
Successfully configured Inbound Translation!
Successfully configured Outbound Translation!
Starting link training...
and then it gets stuck in a while loop in the pciWaitLinkUp() function.
On the ARM side of things I see this at boot:
keystone-pcie: keystone_pcie_rc_init - start

Should I be expecting an auto enumeration from the PCIe driver when I load the DSP with the Example code?
$lspci return nothing also.
