How to generate a DDR templete for STM32DDRFW-UTIL

[ThinhNguyen]

I am going to rebuild STM32DDRFW-UTIL Firmware to do DDR Test on my custom hardware. I looked at this document: https://github.com/STMicroelectronics/STM32DDRFW-UTIL/blob/main/README.md

in section 1.2.3.3 Customization, it mentions about using STM32CubeMX to generate the DDR Templete (stm32mp2xx-ddr4-2x16Gbits-2x16bits-template.h). Unfortunately, I tried the device tree generation function from STM32CubeMx; there was no DDR templete was generated. Is there any instruction to generate the DDR templete?

You maybe using the wrong part of STM32CubeMX. You need to use the special DDR Configurator Tool to get a C Header file (.h file).

Hi @Adam5,

I really can't find it. Can you take a screenshot for me?

Hello @ThinhNguyen 

The file you mention can be found in the STM32DDRFW-UTIL source files:

https://github.com/STMicroelectronics/STM32DDRFW-UTIL/blob/main/DDR_Tool/STM32MP257F-DK/Inc/stm32mp2xx-ddr4-2x16Gbits-2x16bits-template.h

When you generate code with CubeMx, the DDR configuration is located in:

/Workspace/{Project Name}//CA35/DeviceTree/{Project Name}/tf-a/stm32mp25-mx.dtsi

(this is a path example)

I hope this will help you,

Regards.
