Debugging suggestions:
(1) periferal data bus shorted or crossed
(2) general processor halt, check reset, watch dog, power supply ripple, processor clock.
(3) check p_we, p_r/w, p_oe, p_rdy lines.
(4) check LED buffers
(5) check SDRAM data bus bits 16-31, check LSW SDRAM chip.
(6) check SDRAM data bus bits 0-15, check MSW SDRAM chip.
(7) check SDRAM control lines and clocks
(8) check decoupling caps, replace LSW SDRAM
(9) check decoupling caps, replace MSW SDRAM
(10)
(11)
(12)
(13) SDRAM address shorted or unconnected, check sdram caps
