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?
# Ramdisk boot (default)# setenv bootargs 'console=ttyO2,115200n8 root=/dev/ram initrd=0x81000000,16M rw mem=128M'
setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs nfsroot=192.168.2.198:/home/rickie/targetfs,nolock rw mem=128M earlyprintk notifyk.vpssm3_sva=0xBFD00000 ip=192.168.2.197:192.168.2.198:192.168.0.254:255.255.0.0:rickie:eth0:off'
# Add some delay to allow ramdisk to be loaded from RCsleep 1

It is timing problem.
anyway, unfortunately I had other problem as the below.
can you advise to me?
U-Boot 2010.06-svn20597 (Jul 09 2012 - 17:25:16)
TI8148-GP rev 2.1
ARM clk: 720MHzDDR clk: 400MHz
DRAM: 2 GiBMMC: OMAP SD/MMC: 0Using default environment
The 2nd stage U-Boot will now be auto-loadedPlease do not interrupt the countdown till TI8148_EVM prompt if 2nd stage is already flashedHit any key to stop autoboot: 0Card did not respond to voltage select!** Can't read from device 0 **
** Unable to use mmc 0:1 for fatload **## Starting application at 0x80800000 ...
This is the EP console message.
Obviously you should change the env in 1st u-boot.
I use the 8148 but when I choose the pci support , the kernel can't boot up,it stop at
registered ti81xx_vpss deviceregistered ti81xx_vidout deviceregistered ti81xx on-chip HDMI deviceregistered ti81xx_fb deviceregistered ti81xx_vin deviceti81xx_pcie: Invoking PCI BIOS...ti81xx_pcie: Setting up Host Controller...ti81xx_pcie: Register base mapped @0xc8820000
I don't know why ?
