Running DDR_Init on STM32MP135F-DK board

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

Building file: C:/Progetti/dbTechnologies/testSTM32/DDR/Projects/STM32MP135C-DK/Examples/DDR/DDR_Init/Src/main.c
Invoking: GNU Arm Cross C Compiler

Finished building: C:/Progetti/dbTechnologies/testSTM32/DDR/Projects/STM32MP135C-DK/Examples/DDR/DDR_Init/Src/main.c

The commandline for linker is:

C:/Program Files (x86)/Arm GNU Toolchain arm-none-eabi/13.3 rel1/bin/../lib/gcc/arm-none-eabi/13.3.1/../../../../arm-none-eabi/bin/ld.exe: warning: cannot find entry symbol Reset_Handler; not setting start address
Finished building target: DDR_Init_A7.elf
The generated commad lines is quite similar to the ones generated by the STCubeIDE.
Note: please see the warning message for Reset_Handler .. is it critical?

When I upload 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' button the program seems to continue, and the red LED is steady on - the USB STLink LED is flashing red/green.

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

Am I missing some compiler options? Or they are wrong?

Thanks!

Hi @SteMMo ,

 

ST highly recommend to use CubeIDE for an optimal experience. 

Can you try with it and come back if issue still present ? 

 

Thanks

Maybe I solved downgrading the toolchain from 13.3 to 12.3 (??)

I'm investigating ...

Anyone knows issues on gnu arm gcc relase 13.3 ?

Ok, finally I  moved to CubeIDE, I found toolchain 12.3 and evething works,

Thanks
