I have tested the PCIe Boot to use DM8148EVM 2EA
I used the wiki(http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_PCI_Express_Endpoint_Boot_Driver_User_Guide#Setting_up_the_DM814x_RC)
and I got the below result(TI81XX EP Boot completed) but I can't see console message from EP.
How can check EP state? if run EP, can I see console message on EP?
[RC]
