Hi !
I want to write to the flash with the following source code. But after this, my programm is crash and I dont know how is the mistake?! u32 TargetAdd = 0x400C2500; u32 DataWrite = 0x0000222F; u32 Read_Data = 0x00000000; FLASH_Init(); FLASH_WritePrConfig(FLASH_B1F0, DISABLE); FLASH_SectorErase(FLASH_B1F0); FLASH_WordWrite(TargetAdd , DataWrite ); Read_Data=FLASH_WordRead(TargetAdd); printf(''%x\n'',Read_Data); FLASH_WaitForLastTask(); //FLASH_WritePrConfig (FLASH_B1F0,ENABLE); I have read the other threads, but they couldn´t help me further. I use the Keil µVision3 Compiler Thank you in advance for help !Options

Hi
Use address 0x000C2500 not 0x400C2500. The library automaticaly adds the 0x400000000 to the Flash address. Also address C2XXX is in Bank B1F1 not Bank B1F0. Hopes this helps [ This message was edited by: Yvon on 31-10-2006 14:14 ]Options
