Then I followed the instruction to flash the MCU and get the flash verification OK. However, the LED on the board now do not flash after reset, it keep OFF all the time. </p> <p>In the device manager, it does show up a new COM port "Maple R3 (COM23) but the download still fail. same error message "Couldn't find the DFU device: [1EAF:0003]"</p> <p>Any idea? thanks!</p> <p>Here is the Flash screen shown. Was that a correct flashing process?</p> <p>C:\Python26&gt;python stm32loade<br /> Reading data from maple_mini_<br /> Bootloader version 0x22<br /> Chip id '0x4 0x10'<br /> Writing 15744 bytes to start<br /> Write 256 bytes at 0x8000000<br /> Write 256 bytes at 0x8000100<br /> Write 256 bytes at 0x8000200<br /> Write 256 bytes at 0x8000300<br /> Write 256 bytes at 0x8000400<br /> Write 256 bytes at 0x8000500<br /> Write 256 bytes at 0x8000600<br /> Write 256 bytes at 0x8000700<br /> Write 256 bytes at 0x8000800<br /> Write 256 bytes at 0x8000900<br /> Write 256 bytes at 0x8000A00<br /> Write 256 bytes at 0x8000B00<br /> Write 256 bytes at 0x8000C00<br /> Write 256 bytes at 0x8000D00<br /> Write 256 bytes at 0x8000E00<br /> Write 256 bytes at 0x8000F00<br /> Write 256 bytes at 0x8001000<br /> Write 256 bytes at 0x8001100<br /> Write 256 bytes at 0x8001200<br /> Write 256 bytes at 0x8001300<br /> Write 256 bytes at 0x8001400<br /> Write 256 bytes at 0x8001500<br /> Write 256 bytes at 0x8001600<br /> Write 256 bytes at 0x8001700<br /> Write 256 bytes at 0x8001800<br /> Write 256 bytes at 0x8001900<br /> Write 256 bytes at 0x8001A00<br /> Write 256 bytes at 0x8001B00<br /> Write 256 bytes at 0x8001C00<br /> Write 256 bytes at 0x8001D00<br /> Write 256 bytes at 0x8001E00<br /> Write 256 bytes at 0x8001F00<br /> Write 256 bytes at 0x8002000<br /> Write 256 bytes at 0x8002100<br /> Write 256 bytes at 0x8002200<br /> Write 256 bytes at 0x8002300<br /> Write 256 bytes at 0x8002400<br /> Write 256 bytes at 0x8002500<br /> Write 256 bytes at 0x8002600<br /> Write 256 bytes at 0x8002700<br /> Write 256 bytes at 0x8002800<br /> Write 256 bytes at 0x8002900<br /> Write 256 bytes at 0x8002A00<br /> Write 256 bytes at 0x8002B00<br /> Write 256 bytes at 0x8002C00<br /> Write 256 bytes at 0x8002D00<br /> Write 256 bytes at 0x8002E00<br /> Write 256 bytes at 0x8002F00<br /> Write 256 bytes at 0x8003000<br /> Write 256 bytes at 0x8003100<br /> Write 256 bytes at 0x8003200<br /> Write 256 bytes at 0x8003300<br /> Write 256 bytes at 0x8003400<br /> Write 256 bytes at 0x8003500<br /> Write 256 bytes at 0x8003600<br /> Write 256 bytes at 0x8003700<br /> Write 256 bytes at 0x8003800<br /> Write 256 bytes at 0x8003900<br /> Write 256 bytes at 0x8003A00<br /> Write 256 bytes at 0x8003B00<br /> Write 256 bytes at 0x8003C00<br /> Write 256 bytes at 0x8003D00<br /> Read 256 bytes at 0x8000000<br /> Read 256 bytes at 0x8000100<br /> Read 256 bytes at 0x8000200<br /> Read 256 bytes at 0x8000300<br /> Read 256 bytes at 0x8000400<br /> Read 256 bytes at 0x8000500<br /> Read 256 bytes at 0x8000600<br /> Read 256 bytes at 0x8000700<br /> Read 256 bytes at 0x8000800<br /> Read 256 bytes at 0x8000900<br /> Read 256 bytes at 0x8000A00<br /> Read 256 bytes at 0x8000B00<br /> Read 256 bytes at 0x8000C00<br /> Read 256 bytes at 0x8000D00<br /> Read 256 bytes at 0x8000E00<br /> Read 256 bytes at 0x8000F00<br /> Read 256 bytes at 0x8001000<br /> Read 256 bytes at 0x8001100<br /> Read 256 bytes at 0x8001200<br /> Read 256 bytes at 0x8001300<br /> Read 256 bytes at 0x8001400<br /> Read 256 bytes at 0x8001500<br /> Read 256 bytes at 0x8001600<br /> Read 256 bytes at 0x8001700<br /> Read 256 bytes at 0x8001800<br /> Read 256 bytes at 0x8001900<br /> Read 256 bytes at 0x8001A00<br /> Read 256 bytes at 0x8001B00<br /> Read 256 bytes at 0x8001C00<br /> Read 256 bytes at 0x8001D00<br /> Read 256 bytes at 0x8001E00<br /> Read 256 bytes at 0x8001F00<br /> Read 256 bytes at 0x8002000<br /> Read 256 bytes at 0x8002100<br /> Read 256 bytes at 0x8002200<br /> Read 256 bytes at 0x8002300<br /> Read 256 bytes at 0x8002400<br /> Read 256 bytes at 0x8002500<br /> Read 256 bytes at 0x8002600<br /> Read 256 bytes at 0x8002700<br /> Read 256 bytes at 0x8002800<br /> Read 256 bytes at 0x8002900<br /> Read 256 bytes at 0x8002A00<br /> Read 256 bytes at 0x8002B00<br /> Read 256 bytes at 0x8002C00<br /> Read 256 bytes at 0x8002D00<br /> Read 256 bytes at 0x8002E00<br /> Read 256 bytes at 0x8002F00<br /> Read 256 bytes at 0x8003000<br /> Read 256 bytes at 0x8003100<br /> Read 256 bytes at 0x8003200<br /> Read 256 bytes at 0x8003300<br /> Read 256 bytes at 0x8003400<br /> Read 256 bytes at 0x8003500<br /> Read 256 bytes at 0x8003600<br /> Read 256 bytes at 0x8003700<br /> Read 256 bytes at 0x8003800<br /> Read 256 bytes at 0x8003900<br /> Read 256 bytes at 0x8003A00<br /> Read 256 bytes at 0x8003B00<br /> Read 256 bytes at 0x8003C00<br /> Read 256 bytes at 0x8003D00<br /> Verification OK </p>
