Configuration of LPDDR

Hi,

NXP,

I'm using i.MX8M Mini EVK board which is very new for me. I want to know which are the things required to change the SIZE of the LPDDR4. And how to configure the LPDDR. Below the tool i'm using.

1. I'm using DDR_MSCALE_tool_V_3.20

2. RPA for register configuration V18.

But i want to change the RAM from 2GB to 1GB.

I want to know to generate the .ds file.

Hi Vivek

for different memory size recommended to run DDR Test (and use RPA tool) on below

link and change image as described in document: MSCALE_DDR_Tool_User_Guide

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8M-Family-DDR-Tool-Release/ta-p/1104467

also use #define PHYS_SDRAM_SIZE in uboot-imx/tree/include/configs/imx8mm_evk.h

https://source.codeaurora.org/external/imx/uboot-imx/tree/include/configs/imx8mm_evk.h?h=imx_v2020.04_5.4.70_2.3.0
