hi all

    my hardware = TI evm8168(PCIe-RC) + TI evm8168(PCIe-EP)

    my software = ti-ezsdk_dm816x-evm_5_05_02_00

referring to http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_PCI_Express_Endpoint_Boot_Driver_User_Guide

to do boot TI EVM8168 from PCIe inteface ,

this are steps below :

   Setting up the DM816x RC:NAND boot mode

  Setting up DM816x EP:

SW3[5:1] ---> BTM[4:0] = 01000 and SW3[8] ---> CS0BW = 1

SW5[1] ---> PCIe RST = 0 // for both RC and EP

Use Male-Male X1 PCIe cable to connect RC and PCIe slot on EP

Steps for Building for DM81xx Kernel(RC): <M> TI81XX PCIe Endpoint Boot Driver

• Power on EP
• Power on RC

Booting EP:

dm816x-evm login: root
root@dm816x-evm:~# insmod ti81xx_pcie_bootdrv.ko
ti81xx_pcie_ep: No TI81xx PCIe EP [0xb800] found
ti81xx_pcie_ep: No TI81xx PCIe EP [0xb801] found
ti81xx_pcie_ep: No TI81xx PCIe EP found.
insmod: error inserting 'ti81xx_pcie_bootdrv.ko': -1 Operation not permitted
root@dm816x-evm:~#

why TI81xx PCIe EP device not found?

thank you for any help !!!
