How to make the bootloader(IAP) Firmware with STM32L151RE ?

hi. I'm Min-sung Jo.

My MCU is STM32L151RE. I used IAP example source code.

Unfortunately,

it doesn't support STM32L151xE version. so I can't download program on it. first 128 byte succecful download, but anymore not work. I just modified 

Flash_If.c :

&sharpdefine

STM32L1XX_HD

->

STM32L1XX_XL

0x0802FF00

->

0x0803FF00

0x08030000

->

0x08040000

Flash_if.h

&sharpdefine

STM32L1XX_HD

->

STM32L1XX_XL

&sharpdefine APPLICATION_ADDRESS   (uint32_t)

0x08003000

-> &sharpdefine APPLICATION_ADDRESS   (uint32_t)

0x08004000

&sharpdefine USER_FLASH_LAST_PAGE_ADDRESS 

0x0805FF00

-> &sharpdefine USER_FLASH_LAST_PAGE_ADDRESS 

0x0807FF00

&sharpdefine USER_FLASH_END_ADDRESS       

0x0805FFFF

-> &sharpdefine USER_FLASH_END_ADDRESS       

0x0807FFFF

What should I do additionally ? #stm32l151xe #iap

Probably need to fix FLASH_If_GetWriteProtectionStatus(void)

Thank you for reply.

I modified it..

uint32_t FLASH_If_GetWriteProtectionStatus(void)

{ #ifdef STM32L1XX_MD return(FLASH_OB_GetWRP() & FLASH_PROTECTED_SECTORS); #elif defined STM32L1XX_XL uint32_t WRP_Status = 0, WRP1_Status = 0, WRP2_Status = 0,WRP3_Status = 0, sectornumber = 0;

sectornumber=FLASH_SECTOR_NUMBER;

/* Test on the start address in Bank1 */ if (FLASH_START_ADDRESS <= 0x0803FF00) { /* Test on the user application to be programmed in Bank1 */ if (APPLICATION_ADDRESS <= 0x0803FF00) { WRP2_Status = FLASH_OB_GetWRP2(); WRP3_Status = FLASH_OB_GetWRP3();

if(sectornumber < 32)

{ WRP_Status = FLASH_OB_GetWRP() & ((uint32_t)~((1<<sectornumber) - 1)); WRP1_Status = FLASH_OB_GetWRP1(); } else { WRP1_Status = (FLASH_OB_GetWRP1() & ((uint32_t)~((1<<(sectornumber-32)) - 1))); } } else if (APPLICATION_ADDRESS >= 0x08040000) /* Test on the user application to be programmed in Bank2 */ { sectornumber = (uint32_t)((APPLICATION_ADDRESS - 0x08040000)>>12); if (sectornumber < 32) { WRP2_Status = FLASH_OB_GetWRP2() & (uint32_t)~((1 << (sectornumber + 32) - 1)); WRP3_Status = FLASH_OB_GetWRP3(); } else { WRP3_Status = FLASH_OB_GetWRP3() & (uint32_t)~((1 << (sectornumber-32) - 1)); } } } /////////////////////////down.. never operate.. no think about... else if (FLASH_START_ADDRESS >= 0x08040000) /* Test on the start address in Bank2 */ { if (APPLICATION_ADDRESS <= 0x0803FF00) /* Test on the user application to be programmed in Bank1 */ { sectornumber = (uint32_t)(APPLICATION_ADDRESS - 0x08000000)>>12; if(sectornumber < 32) { WRP_Status = FLASH_OB_GetWRP() & (uint32_t)~((1<<sectornumber - 1)); WRP1_Status = FLASH_OB_GetWRP1()&0x0000FFFF; } else { WRP1_Status = (FLASH_OB_GetWRP1() & (uint32_t)~((1 << (sectornumber-32) - 1)))&0x0000FFFF; } } else /* Test on the user application to be programmed in Bank2 */ { if(sectornumber < 16) { WRP1_Status = FLASH_OB_GetWRP1() & ((uint32_t)~(1 << (sectornumber + 16) - 1)); WRP2_Status = FLASH_OB_GetWRP2(); } else { WRP2_Status = (FLASH_OB_GetWRP2() & (uint32_t)~(1 <<( sectornumber - 16) - 1)); } } } if ((WRP_Status!=0)||(WRP1_Status!=0)||(WRP2_Status!=0) || (WRP3_Status != 0)) return 1; else return 0;

#endif

} is it right?

I find strange thing. that is I add the register WRPR3.

WRPR, WRPR1 and WRPR2 immediatly are exist. 128k + 128k + 128k +128k(add) = 512k... register window of My compiler didn't display WRPR. I can see WRPR1, WRPR2 and WRPR3. I use IAR. what should I do?

I'm not a user of the L151RE, or IAR, and haven't looked at the exact mapping of the flash protection registers.
