Hello,

This can be done through DDR tool in Config Tools for i.MX. You need to enter your memory features and this will generate a initialization/timing script for DDR configuration. If you need to change some register value, you can do it in this generated scripts.

Config Tools for i.MX Applications Processors | NXP Semiconductors

Here you can consult more information about how to use the tool:

User Guide for Config tools for i.MX

And here how to implement it in software in section 4.5 Building u-boot image:

Hi jorge,

We need to use User Guide for Config Tools for i.MX
this link document to create lpddr4x_timing.c file , in which section we need to refer,

We have our custom board yocto build, we need to add FSP support on lpddr4x_timing.c file, adding two FSP support on IMX93.

Hello,

Please refer to section 6 DDR Tool.

With FSP are you referring to frequency set point?
