hi,

In tms320dm8168.pdf -revised january 2013 we found " Memory device capacity: 64Mb, 128Mb, 256Mb, 512Mb, 1Gb, 2Gb and 4Gb (x16-bit only) devices",

what "4Gb (x16-bit only)"mean?

Does TMS320DM8168BCYG2 support MT41J256M16HA-125(micron,Density:4Gb,depth:256Mb,width:X16,clodk Rate:800MHz,cl=11,DDR3-1600)?

Hi Chand,

Yes it does. I think the note "4Gb (x16-bit only)" comes from the fact that there are only 15 address lines on the EMIF (A0 - A14), and 4Gb x8-bit needs 16 address lines (A0 - A15) for row addresses.

Hi Biser,

We use this 4Gb DDR3，there is nothing on UART when the board powered on .we use BTMOD from SD,the MMC_POW is enabled and can measured MMC_CLK when powered on. is there anything esle we must pay attention?
