Thanks for the update, I noticed that changing PECFG_POM0LAL to 0xB0000000 instead of 0x00000000 in 440spe_pcie.c seems to get rid of the bus error. I don't have a YUCCA board so i cannot verify it but worth the try. Another strange thing i noticed was that i have a multifunction device on PCIE0. U-boot, however would only detect function0. pci display 1.1.0 succeeds but pci display 1.1.1 fails to detect. This might be my device problem. Its a tachyon. Just curious if anybody had trouble detecting multifunction device on PCIE??
Thanks again Pankaj

Dear Pankaj,

I have been using u-boot-1.1.5 on my custom 440SPe based board. I am able to establish a link on PCIE0. However, I am having trouble accessing outbound Memory on PCIE0. My memory map seetings for Outbound PCIE memory are the default U-boot Settings. I was curious if anybody's tried accessing PCIE Outbound memory with the default settings. I seem to get a bus error when I try to access that region.
I confirm that there is some problem with PCIe on these systems. We're working on this right now. Please stay tuned.
Best regards,
Wolfgang Denk
