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.
