STM32MP135F-DK problem running DDRInit project

[Sxx]

I'm trying to run my application compiled and linked for DDR on STM32MP135F-DK.

Following the wiki istruction it's necessary preliminary to run the DDRInit project on SYSRAM that initialize the DDR and then execute my custom program.

When I execute the DDRInit project the DDR configuration seems to be ok but when ddr_test_data_bus() is executed it fail at the first DDR base address 0xC0000000.

Can someone explain to me why?

Thanks in advance.

Hi @Sxx ,

Can you please confirm you are using our latest delivery V1.1.0 ? 

The provided DDR_Init is supposed to work as is.

Can you maybe further describe how you proceed? 

Using Engi boot or booting from SD ? 

Thanks

Hello Olivier.

Thanks for your time but I have understand my mistake.

I'm trying to run the DDRInt project finded inside the STM32MP13XX_CUSTOM_HW folder but using a DK board instead to use the same project on STM32MP135C-DK folder. 

Now I have checked and is all working as is!

Thanks for your support.
