Compiling DDR_Init project

[SteMMo33]

Hi all, i'm trying to run the DDR_Init project as my first project, I own a STM32MP135F-DK board. I loaded the project on CDT Eclipse IDE and added some configurations: the build is ok. I report the main.c compilator command line as example:

When I download the binary on board by GDB OpenOCD Debug profile, the run breaks with the message:

Break at address "0x4904" with no debug information available, or outside of program code.

I don't think this is the main() entry point .. If I press 'Resume F8' the program seems to continue, and the red LED is steady on.

I also added some other breakpoints (in the main function) but none of them breaks.

Today I downgraded the arm gcc toolchain from release 13.3 to 12.3. Rebuilding the project seem to be solved. Are there known issues about that ??

Thanks!

I solved with STM32Cube environmet.
