Simple STM32CubeIDE project with .ioc file for STM32MP2

[fa31]

Hi, I am using STM32MP257F-DK microcontroller. I have never used a dual cortex before. All I want to do is to generate a simple STM32CubeIDE project which also has a .ioc file. I want to debug it via CubeIDE.

1) Do I need OpenAmp to successfully flash the code?

2) I have already set up the SDK, are there other settings I need to take care of?

When I try to flash my current project, It always stops at 78% like shown in the picture below.

I am a little confused - are you using STM32MP157F-DK or STM32MP257F-DK ? I could provide a sample code + all related setup, but first clear about correct hw. Thanks

Hi! Thank you for the reply and sorry for the delay, I was a bit busy with another project.

I am using STM32MP257F-DK, mentioned the wrong one in my post.

It will be really helpful to get the example code.

Hello fa31,

Could you please check the GDB debugger on the debug Configurations 

BTW : could you please share the log .

My boot switch settings:

Boot 0 = ON

Boot 1 - 3 = OFF

Here are my debug settings:

Then clicking on the "Debug" button gives the following response:

And the following output log is printed to the console:

Hei,

Maybe this is happening due to signing problems. 

The example project, OpenAMP_TTY_echo, runs successfully. And it had the following post build command:

arm-none-eabi-objcopy -S ${BuildArtifactFileBaseName}.elf ${BuildArtifactFileBaseName}_stripped.elf; python ../../../../../../../../../Utilities/optee_os/scripts/sign_rproc_fw.py --in ${BuildArtifactFileBaseName}_stripped.elf --out ${BuildArtifactFileBaseName}_sign.bin --key ../../../../../../../../../Utilities/optee_os/keys/default.pem --plat-tlv BOOTADDR 0x80100000

The post build command setting is located here:

right click on the "OpenAMP_TTY_echo_CM33_NonSecure (in NonSecure)" project -> properties -> C/C++ Build -> Settings -> Build Steps -> Post-build steps

This confirms that the project needs to be signed. So I did the same to my project. It builds successfully and generates a signed binary which I can then run on the STM32MP257F-DK. But running the generated signed bin file gives the following error:

I need help to find the right way to sign the binaries, the correct keys to use and the correct entry point address and other needed settings.
