Posted on January 29, 2016 at 12:50I'm trying to flash memory using stm32f10x_flash library. here the code:
/*in the arm-gcc-link.ld file i added this lines to allocate rom memory for my data*/
.dataconf 0x0807F000:
{
KEEP(*(.ROMDATA))
*(.dataconf*)
} > rom
/*I declared this in the main.c to allocate rom memory */
const uint16_t Pat __attribute__((section (''.ROMDATA'')));
/* finally the function to flash memory (always in main.c) */
void FlashMemory(void)
{
uint16_t IDPat = 1;
FLASH_Status FlashStat;
FLASH_Unlock();
FLASH_ClearFlag(FLASH_FLAG_EOP | FLASH_FLAG_PGERR | FLASH_FLAG_WRPRTERR);
FlashStat = FLASH_ProgramHalfWord(0x0807F000, IDPat);
FLASH_Lock();
}
FlashStat is FLASH_ERROR_PG.
can you tell me what it means and where is the error?
