[U-Boot-Users] PQ2FADS-ZU PQ28280 access to 60x bus SDRAM failed when localbus is in PCI mode?

Hi; I am having trouble with my PQ2FADS-ZU board with a PQ2 8280 processor that when the localbus is put into PCI mode with LBPC = 01, all accesses to 60x bus SDRAM fails. Uboot failed in get_ram_size() routine. The selection of localbus operation mode is done by SW9. Switch the jumper back to localbus SDRAM mode, U-boot boots to the prompt and access to 60x SDRAM is fine. Does anybody have similar experience? Any insight is appreciated.
