  Hi All, I have a board. one tms320c6203,one sdram(MT48LC4M32B2TG-7 IT),dual-ram.When
production date of sdram is 0608,DSP access sdram ok.When poduction date of sdram is 0704,DSP
access sdram error.For example DSP writes 0x55 to sdram,then DSP writes 0xaa to sdram.The data
of sdram will remain 0x55.The data 0xaa
can not write in sdram.DSP should read SDRAM once.The data 0xaa can  write in sdram.
   Thanks
