Dear Friends.

Does anyone use Flash loader Demonstrator for STM32F0? I try out and work hard 2 days for boot loader of STM32F0 with Flash demonstrator but It is still not working. I'm using STM32F0DISCOVERY. I set boot 0 is high leve with 10K pull up. I try how to use boot loader with evaluation board STM32F1, STM32F2 are always successful.

I don't know we need to set BOOT1. I see in AN2606 setting BOOT 1 pin is optional bytes. Anyone help me how can to do that.

#thanks-for-your-help-!-!

Hi,

I got the same problem, I don't know how to move the nBOOT1 pin.

I have tried via software with the FLASH functions but with no good result.

Also I am working with the J-link no with the ST-Link.

The code I have used is taken from the AN 3310 and ported for the F0 micro:

FLASH_Unlock();

FLASH_OB_Unlock();

FLASH_ClearFlag(FLASH_FLAG_EOP|FLASH_FLAG_WRPERR |FLASH_FLAG_PGERR |FLASH_FLAG_WRPERR | FLASH_FLAG_BSY );

FLASH_OB_UserConfig(OB_IWDG_SW, OB_STOP_NoRST, OB_STDBY_NoRST);

if (FLASH_OB_BOOTConfig(OB_BOOT1_RESET) == FLASH_COMPLETE)

{

/* generate System Reset to load the new option byte values */

FLASH_OB_Launch();

}

The function BOOTConfig returns FLASH Erorr, got form the previous operation.

Thanks
