STM32H743I-EVL example not working with STM32H757I-EVL board

I have purchased STM32H757I-EVL board for working. I have not found SDK for this board. But as one of site suggest downloading STM32CubeH7 package, I did same. In this package I couldn't find example project for STM32H757I-EVL board.
So, I have start working with STM32H743I-EVL example code and compile Thread Creation example. Now I am flashing generated .elf file to STM32H757I-EVL board but this application is not working, and LED is not blinking. I have soldered resistor for LED that is only change on board. I have checked schematic for both board and found it is pin compatible. Now I am stuck to go further. Please anyone found this type of issue or help on this. Meanwhile I will try further and debug issue.
Example code path is STM32CubeH7\Projects\STM32H743I-EVAL\Applications\FreeRTOS\FreeRTOS_ThreadCreation\STM32CubeIDE.

Hello @bharatbhardava and welcome to the ST Community

First the STM32H757I-EVL is based on a Dual Core (Cortex-M7 and Cortex-M4) MCU. But the STM32H743I-EVL is based on the Cortex-M7 (one Cortex only). So, For the STM32H757I-EVL, it may have some issues with examples made based on the STM32H743I-EVL. I suggest you use the examples made for the STM32H747I-EVL. The H757I-EVAL is Same as H747I-EVAL but with HASH and CRYP unit.​

Best Regards.
