Hello,

 

After changing the data width from 64 to 32, I could see that the available memory is only 512MB.

Any advice on what other changes are needed to be able to have 1GB of RAM and using 32 bit data width?

 

Board : SABRE board i.MX 6 QUADPlus , 1GB DDR3 RAM

u-boot version  : rel_imx_4.1.15_1.0.0_ga

File: mx6sabresd.c

static struct mx6_ddr3_cfg mem_ddr = {
.mem_speed = 1600,
.density = 4,
.width = 32, //64
.banks = 8,
.rowaddr = 14,
.coladdr = 10,
.pagesz = 2,
.trcd = 1375,
.trcmin = 4875,
.trasmin = 3500,
};
