Hi

I am using

STM32439I-EVAL

board. I want to program my board via ethernet. I searched and i could find an example in ST web site.

https://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32-standard-peripheral-library-expansion/stsw-stm32070.html

I downloaded it and run it via IAR. In the main.h file there are 3 macros that called :

&sharpdefine USER_FLASH_FIRST_PAGE_ADDRESS 0x08010000

&sharpdefine USER_FLASH_LAST_PAGE_ADDRESS  0x080E0000

&sharpdefine USER_FLASH_END_ADDRESS        0x080FFFFF

I set these macros like above but the example doesn't work!

please help me how to set these macrose ...

What does 'doesn't work' mean here, it's not a very specific failure. Does it compile? Does the Ethernet and data transfer portion work? Does the Flash write or erase fail?

HAL based example

Thanks for your quick answer

The program is compiled correctly and Ethernet and data transfer portion work well.

in the main.c file we have

if (((*(__IO uint32_t*)USER_FLASH_FIRST_PAGE_ADDRESS) & 0x2FFE0000 ) == 0x20000000)

    {

      /* Jump to user application */

      JumpAddress = *(__IO uint32_t*) (USER_FLASH_FIRST_PAGE_ADDRESS + 4);

      Jump_To_Application = (pFunction) JumpAddress;

      /* Initialize user application's Stack Pointer */

      __set_MSP(*(__IO uint32_t*) USER_FLASH_FIRST_PAGE_ADDRESS);

      Jump_To_Application();

    }

    else

    {/* Otherwise, do nothing */

      /* LED3 (RED) ON to indicate bad software (when not valid stack address) */

      LED_On(3);

      /* do nothing */

      while(1);

    }

The if statement condition is always False and the program go to the infinit loop .
