Posted on January 10, 2013 at 10:49Hi,
I am not able to Erase/program the flash .
FLASH_ErasePage : is returning FLASH_COMPLETE but I still see old data on flash.
FLASH_FastProgramWord : inside this function first it is checking for last operation status but ''FLASH_WaitForLastOperation'' is always returning FLASH_ERROR_PROGRAM.
Erase Code:
FLASH_Unlock();
FLASH_OB_Unlock();
fstatus = FLASH_OB_WRPConfig(OB_WRP_Pages64to79 | OB_WRP_Pages80to95 | OB_WRP_Pages96to111 | OB_WRP_Pages112to127
,DISABLE);
printf(''write protection=%x\n'',fstatus);
for(i=0;i<64;i++)
{
printf(''page-addr=%x\n'', ((i*1024)+faddr) ); //faddr - 0x08010000
fstatus = FLASH_ErasePage( ((i*1024)+faddr) );
printf(''Erase status=%x\n'',fstatus);
if(fstatus != FLASH_COMPLETE )
break;
}
fstatus = FLASH_OB_WRPConfig(OB_WRP_Pages64to79 | OB_WRP_Pages80to95 | OB_WRP_Pages96to111 | OB_WRP_Pages112to127
,ENABLE);
printf(''write protection=%x\n'',fstatus);
FLASH_OB_Lock();
FLASH_Lock();
Flash Program Code: flashaddr = 0x08010000
FLASH_Unlock();
FLASH_OB_Unlock();
fstatus = FLASH_OB_WRPConfig(OB_WRP_Pages64to79 | OB_WRP_Pages80to95 | OB_WRP_Pages96to111 | OB_WRP_Pages112to127
,DISABLE);
printf(''dwrite protection=%x\n'',fstatus);
/* FLASH_ClearFlag(FLASH_FLAG_BSY | FLASH_FLAG_EOP| FLASH_FLAG_PGAERR | FLASH_FLAG_WRPERR); - is always hitting assert_param(IS_FLASH_CLEAR_FLAG(FLASH_FLAG)); */
fstatus = FLASH_FastProgramWord(flashaddr,fword);
if(fstatus != FLASH_COMPLETE)
{
printf(''write fstatus=%d\n'',fstatus);
ASSERT(0);
}
fstatus = FLASH_OB_WRPConfig(OB_WRP_Pages64to79 | OB_WRP_Pages80to95 | OB_WRP_Pages96to111 | OB_WRP_Pages112to127
,ENABLE);
printf(''dwrite protection=%x\n'',fstatus);
FLASH_OB_Lock();
FLASH_Lock()
