STM32 - Flashowanie przez USB

Przypuszczam, że nie chodzi Ci o flashowanie stricte przez USB ;> ? Może być przez wbudowaną w zestaw przejściówkę USB-UART? Do poczytania. W załączniku archiwum ze sterownikiem do przejściówki USB<->UART (PL2303). Profilaktycznie możesz sprawdzić czy w Twoim zestawie nie ma czasem innego układu. Po zainstalowaniu sterownika system Windows ma wykrywać coś w stylu "Prolific USB to serial com port". Uwaga - musisz podłączać się do gniazda USB oznaczonego CN3 na płytce. Program do flashowania -> "Flash Loader Demonstrator" - ściągasz ze strony ST. Jeśli korzystasz z linuksa to driver do przejściówki raczej nie będzie potrzebny, a zamiast Flash Loader Demonstratora możesz wykorzystać stm32flash. Żeby uaktywnić bootloader postępujesz tak jak napisał McMonster. Ten mikrokontroler nie ma bootloadera DFU, więc program "dfuse" nie zadziała. Jeśli chcesz korzystać z flashowania bezpośrednio przez USB i program "dfuse" to musisz zaprogramować mikrokontroler odpowiednim wsadem. ST pewnie udostępnia gotowca w bibliotece USB.

Counterfeit Warning!!!
Please be warned that counterfeit/fake PL-2303HX Rev A (or PL-2303HXA) USB-to-Serial Controller
ICs using Prolific's trademark logo, brandname, and drivers, are being sold in the China market.
Counterfeit IC products show exactly the same outside chip markings but generally are of poor quality
and causes Windows driver compatibility issues (Yellow Mark Error Code 10 in Device Manager under
WinXP, Vista, and 7). This warning is issued to all customers and consumers to avoid confusion and
false purchase. Please purchase only from stores or vendors providing technical and RMA support.

Windows 7 Driver Installation
This section will guide you on how to install the PL-2303 Windows Driver. You can download the latest
Driver Installer program from Prolific Support website:
http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=225 &amp; pcid=41
Note: Please take notice of the installation order. First, run the Driver Installer Program before
plugging in the USB to Serial adapter. If you already plug the device during the driver installation, you
need to re-plug the device for Windows to enumerate the device and load the drivers installed. If your
device is embedded to the system, you might need to restart the system (or click rescan hardware
changes in Device Manager) to reload and install the driver.
The following steps will show how to install the device under Windows 7 (64-bit) OS as this is the most
inquired driver installation support received by Prolific. The procedures are the same and straightforward for all other supported Windows operating system versions.
