Flash_error_pg

It is more worse. Parameters: FLASH_Latency,:specifies the FLASH Latency value. Note:This function can be used for all STM32F10x devices. Definition at line 299 of file stm32f30x_flash.c. 00300 { 00301 FLASH_Status status = FLASH_COMPLETE; 00302 00303 /* Wait for last operation to be completed */ 00304 status = FLASH_WaitForLastOperation(FLASH_ER_PRG_TIMEOUT); 00305 00306 http://bigvideogamereviewer.com/general/flash-error-program.html

Now it works fine. Every 16 bit of the option byte area can only be written one time after an erase command to the option byte flash. Each one can occur in one of many hundreds of locations in the system. 5.2.1.0 (29/02/2016) File size: 7.5 Mb Click to Verify - This site chose Symantec SSL for secure Parameters: None Return values: None Definition at line 228 of file stm32f30x_flash.c. 00229 { 00230 if((FLASH->CR & FLASH_CR_LOCK) != RESET) 00231 { 00232 /* Authorize the FLASH Registers access */ 00233 https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/AllItems.aspx?RootFolder=%2Fpublic%2FSTe2ecommunities%2Fmcu%2FLists%2Fcortex_mx_stm32%2FSTM32%20FLASH%20Page%20Write%20Protection

For STM32F10X_XL devices, this function clears Bank1 or Bank2ís pending flags For other devices, it clears Bank1ís pending flags. The processor expects to see valid code, loaded at the correct address, failing this it will crash. Parameters: None Return values: FLASHStatus: The returned value can be: FLASH_ERROR_PG, FLASH_ERROR_WRP, FLASH_COMPLETE or FLASH_TIMEOUT.

Is that correct?OwenShare PostPosted: 3/3/2015 7:53 PMView Properties/AttachmentsReplyclive1 Posts : 6439I haven't used STM32F1 parts actively for several years, but yes I believe you'd have to save whatever content you Once the Programmming is complete, verify byte-by-byte the programmed code and the code for programming. 4. However all things considered a proper Hard Fault Handler will tell you exactly what instruction is faulting and the context in which it occurs, a while(1) loop will not. If the loader is now 0x5000-0x57FF in size consider if 0x6000 is more appropriate.

My custom bootloader shall be able to run in an user thread (embOS using). Here is the code I ended up with.

FLASH_Status FLASH_EraseAllPages ( void ) Erases all FLASH pages. FLASH_StatusFLASH_ReadOutProtection (FunctionalState NewState) Enables or disables the read out protection.

Parameters: FLASH_FLAG,:specifies the FLASH flag to check. see here For other devices, it checks whether the specified Bank1 flag is set or not. For all other devices it Locks Bank1 and it is equivalent to FLASH_Lock function. FLASH_Status FLASH_GetBank1Status ( void ) Returns the FLASH Bank1 Status.

Thanks again for your help! void FLASH_HalfCycleAccessCmd ( uint32_t FLASH_HalfCycleAccess) Enables or disables the Half cycle flash access.

Function Documentation FLASH_Status FLASH_EraseAllPages ( void ) Erases all FLASH pages. Note:To correctly run this function, the FLASH_Unlock() function must be called before. Your option here is to get a Hard Fault Handler that can decompose the failing state, and understand why you are getting the fault. his comment is here Parameters: None Return values: FLASHPrefetch Buffer Status (SET or RESET).

Call the FLASH_Lock() to disable the flash memory access (recommended to protect the FLASH memory against possible unwanted operation) Parameters: Page_Address,:The page address in program memory to be erased. For now, the only difference with a standard application is the starting address. Thus some functions manages all devices, while other are dedicated for XL devices only.

For all other devices it unlocks Bank1 and it is equivalent to FLASH_Unlock function.

voidFLASH_Unlock (void) Unlocks the FLASH Program Erase Controller. Note:A Page is erased in the Program memory only if the address to load is the start address of a page (multiple of 1024 bytes). Parameters: None Return values: FLASHStatus: The returned value can be: FLASH_BUSY, FLASH_ERROR_PG, FLASH_ERROR_WRP or FLASH_COMPLETE Definition at line 1515 of file stm32f10x_flash.c. Parameters: Address,:specifies the address to be programmed.

Parameters: None Return values: None Definition at line 392 of file stm32f10x_flash.c. After fixing the registry, a quick scan with Spyhunter anti-malware tool will ensure that your PC has no more problems! Parameters: FLASH_Pages,:specifies the address of the pages to be write protected. weblink I don't know the assembly but I give you the first instructions that should be executed if it can helps : 0800f000:   stmia r0!, {} 0800f002:   movs r0, #0 0800f004:   cmp

Parameters: FLASH_PrefetchBuffer,:specifies the Prefetch buffer status. The Interrupt vector table...If you are using 2 independent code in 2 segments. Note:This function can be used for all STM32F10x devices, it is equivalent to FLASH_WaitForLastBank1Operation. Parameters: None Return values: TheFLASH Write Protection Option Bytes Register value Definition at line 1228 of file stm32f10x_flash.c.

For all other devices it waits for a Flash operation to complete or a TIMEOUT to occur. voidFLASH_PrefetchBufferCmd (uint32_t FLASH_PrefetchBuffer) Enables or disables the Prefetch Buffer. Parameters: None Return values: FLASHStatus: The returned value can be: FLASH_BUSY, FLASH_ERROR_PG, FLASH_ERROR_WRP or FLASH_COMPLETE Definition at line 1477 of file stm32f10x_flash.c. void FLASH_Lock ( void ) Locks the FLASH Program Erase Controller.

FLASH_Status FLASH_EraseOptionBytes ( void ) Erases the FLASH option bytes. FLASH_Status FLASH_UserOptionByteConfig ( uint16_t OB_IWDG, uint16_t OB_STOP, uint16_t OB_STDBY ) Programs the FLASH User Option Byte: IWDG_SW / RST_STOP / RST_STDBY. Return values: FLASHStatus: The returned value can be: FLASH_ERROR_PG, FLASH_ERROR_WRP, FLASH_COMPLETE or FLASH_TIMEOUT. I hope that after the next answer it will works.
