Hi All,

We have build a custom board with i.mx280 and ddr2 from micron 64mb.Looks like its memory timing issue, we are using default bootlet setting , with obvious change , bank size to 4 banks and SDRAM_SIZE .

Issue we see : when writer to DDR2 ( DDR base to max size), its fails after some writer ( random ) , so if we add delay write and read and then write , work well.


So , this looks like memory timing issue. 

Will appreciate any one have experience dealing this issue , point me in right direction !!!!

Any help appreciated !!!


Thanks ,
