SOC:IMX6Q

Platform: custom board similar to imx6q-sabresd

BSP:L4.1.15_1.0.0

 

when i try to enable pcie module of IMX6Q in kernel,some errors happened:

>>imx6q-pcie 1ffc000.pcie:phy link nerver came up

>>imx6q-pcie 1ffc000.pcie:DEBUG_R0:0x000abc43,DEBUG_R1:0x08000000

>>imx6q-pcie 1ffc000.pcie:failed to initialize host

 

the hardware architecture of the use of pcie module on my custom borad:

imx6q(pcie contoller)->pex8619->LAN82575(pcie device)

 

There are questions:

1.phy link nerver came up that means the problem come from the link between pcie core and pcie phy(both are in imx6q) or between pcie phy and pcie device eg.pex8619 or LAN82575?

2.According to error logs above,any suggestions?
