How to use DDR3 CS0 and CS1

Steve Tsai

Intellectual 380 points

We have a DM8148 board which uses DDR3 CS0 and CS1 in EMIF0. When we enable CS1, the system will not stable. Someone said CS1 is not usable in DM8148 DDR controller. Does anyone know why DDR CS1 is not usable? Does it have good reason?

Thanks, Viet. Will CS1 be supported in the future? If TI will support CS1, TI will modify hardware or software to fix it.

Steve,

Unfortunally, we are not going to support CS1 in future release either. Please check the device errata in TI product folder for the work around.
