Hi,
I am using iMX6UL in my custom board. Right now i am using 512MB DDR3L DRAM and 1GB NAND Flash.
I want to know maximum density supported for DRAM and Flash memory.
I got max density is 1GB for DDR3/3L from Table 34-1 in iMX6UL Ref Manual, Rev 0. & 2GB for LPDDR2 as there are two chip selects for LPDDR2. Please correct me if I am wrong.
I didn't found max density support for NAND and eMMC memories. Please let me know the density and reference in ref manual.
Seeking for your earliest response.
Regards,
Ritesh.
Hello,
Maximum DRAM memory size is 2GB. Please refer to Table 2-1 (System memory map)
of the i.MX6 UL Reference Manual.
As for NAND - there are no i.MX6 hardware / specified restrictions on supported size.
Have a great day,
Yuri

As per Table 2-1 Max DRAM size is 2GB. That is for LPDDR2 memory.
For DDR3/3L, As per table # Table 34-1 on Page # 2049 of iMX6UL Ref manual, Max density per DDR device is 1GB, and out of Two chip selects there is only one Chip select for DDR3/3L.
That means we can interface max 1GB DDR3/3L DRAM memory. Please confirm.
Hello,
The i.MX 6UltraLite supports single Chip Select DDR3 memory with CS0_B, ODT0, and SDCKE0.
data bus width = 16 bit ;
Column size = (up) 12 bits ;
Row size = 16 bits ;
banks = 3 bits.
Such parameters allow to address all available 2GB area.

Yuri.
