setting MMU on stm32mp157

[Roman Andronov]

Please show me a working example of setting up the MMU for STM32MP157D-EV1. and where to place the Translation table correctly (for cortex A7)

It is assumed that all data and program will be located in DDR memory, without using the OS

HI @Roman Andronov 

MMU settings are automatically handled by our OpenSTLinux deliveries. You don't have (and you can't) setup it directly.

If you are playing bare-metal, please note that STMicroelectronics did not provide any bare-metal support on STM32MP15 series. You have to check with ST partners https://www.st.com/content/st_com/en/partner/partner-program.html?key=STM32MP&country=country#2 .

Nevertheless, as we provide bare-metal support on STM32MP13 series thru STM32CubeMP13 delivery.

As this device use same Cortex-A7 (but single core only) and very close HW, maybe you could get some insight from this delivery.

Regards

The latest version of StmCubeMX does not correctly create a project for stm32mp13 bare-metal (for STM32MP135F-DK)

there is no .cproject file with environment settings, as well as a linker file
