Hi,All

     My board is i.MX6SL,and when I read reference manual, I found MMDC Core Address Space Partition Register(MMDC_MDASP) said  Field CS0_END(6-0) have the relation between density and value  (i.MX6SLRM.pdf   P2032)  :

000_0000 256Mb

000_0001 512Mb

001_1111 8Gb (1GB)

011_1111 16Gb (2GB) - default

111_1111 32Gb (4GB)

 

but I also refer to (0x80000000 + density_per_CS)/0x2000000 -1

and I found the result is not equal to the value above. For example,

per_CS_density is 512 Mb ,1CS (and now this Lpddr2 is used by my board) and result is

(0x8000_0000 +0x2000_0000)/0x200_0000-1=0x4F    but value above is 000_0001

so can you give me some explains?
