A problem about PCIe of DM8168

meng lv

Hi, TI engineer:

I have a problem about PCIe of DM8168,

I have TMDXEVM8168 and I want to use it as PCIE endpoint to communicate with x86 host(as RC),

I find less doc and demo code about this,could you tell me something about how can I setting up test environment like this?

I only find

saBootApp.c

DM816x_AM389x_PCI_Express_Endpoint_Boot_Driver_User_Guide.pdf

DM816x_AM389x_PCI_Express_Root_Complex_Driver_User_Guide.pdf,

is there any other doc or code ?

Thank you

Hi,

I guess you may be able to get more information on Endpoint other than the boot driver you have mentioned @ http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_PCI_Express_Endpoint_Driver_User_Guide

Hi Sandeep R
I have anther question
I regard the ti8168 which is a cuntom board as a PCIe ep,
but I am not use the PCIe boot mode
and I won't initialze the ep'PCIESS until the linux kernel start.
I think It is to late for ep'initialization
So I wander whether it will lead to the pc BIOS hungs
