Application Note:
[1] Because lack of Address pin A15 in package, following SoCs do not support the 512M*8 DDR3: RK2906-6,RK2906-8,RK3066.
[2]The DRAM Part Number usually consists of two parts divided by '-', which the first part contains memory type, density, orgainization, package, and the second part usually means data rate.
We don't care about the second part.
[3]RockChip platform can support all the chips that match the first part of Part Number which marks '√' or 'T/A', and do not nee d to care the second part. If you want your system running more effective , you may need to find out the exact data rate in DRAM datasheet and config in kernel menuconfig.
[4]Please copy the Rockchip reference design model of DRAM area PCB Layout directly without any modification and follow the PCB layout rules from Rockchip.
Contact information: fae@rock-chips.com [5]Only support for RK3128.
[6]The DRAM's VDD and VDDQ should powered by 1.5V when it used on these SoCs.
