+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
