![]() ![]() ![]() COM port driver - With Windows 10 and Windows 11 the required driver will be installed by Windows when you connect your tinySA to a USB port. The other driver is required when you want to do firmware updates on your device. One is required to get a COMxx: port so that your PC can exchange data with a tinySA. Now how does this apply to a tinySA software installation? There are two different driversrequired when using a tinySA or tinySA Ultra. If Memory Integrity is On it will block suspicious or non-compliant divers from installing or loading and you will usually see a yellow triangle with an a exclamation mark. So the user will only know if Memory Integrity is on or off by examining their computer settings. The manufacturer installs drivers, applications and sets Windows settings as they see fit for the product they are selling. However most PC's purchased by users come from a manufacturer with Windows pre-installed. When Microsoft ships Windows 10 Memory Integrity is turn OFF by default and with Windows 11 it is turned ON by default. It is described in the Microsoft post below. Memory integrity can help prevent malicious code from accessing high-security processes in the event of an attack. I believe that some of the problems have to with a security feature in Windows 10 and 11 called Memory Integrity. Some have been able to easily install the drivers while others have been frustrated. There have been several posts over the last few months where users have had issues trying to install drivers for the tinySA and TinySA Ultra. Remember, the correct installation of the ST-Link driver is of utmost importance upon obtaining your board.I have posted on this topic several times but it seems to get buried so I have started a new post for future reference. In order to communicate with the board over UART, you use the ST-Link Virtual COM Port interface, and your host application or host IDE uses STMicroelectronics STLink dongle interface, which is an interface used for debugging. When your Nucleo board is connected, a COM port will be visible under “Ports,” and the “STMicroelectronics STLink dongle” option will appear in “USB devices” (Figure 8) Upon completion of the installation, click “Finish” (Figure 7).įigure 6. The software will install the WinUSB driver (Figure 6), which is required in order to talk to the ST-Link, and it also installs other drivers.Within it, you’ll find two applications (Figure 4), one for 32-bit and the other for 64-bit systems. Upon downloading, access the folder where the driver is stored.ST-Link driver installation link for Windows. You will get a USB driver for those boards with ST-LINK/V2 and ST-LINK/V2-1 ST-Link circuitry.Īt the end of the website, you will find the driver link (Figure 3), and proceed to download it. Visit the ST website and navigate to STSW-LINK009, as indicated in Figure 2.ST-LINK Driver for Windows (32/ 64-bit versions 7, 8, and 10): ST-Link in-circuit debugger and programmer. The ST-Link driver means the driver for the ST-Link in-circuit debugger and programmer interface, as depicted in Figure 1. Once you have your ST board that may be either discovery, Nucleo, or any other board from ST, which is based on ST-Link in-circuit debugger and programmer, then in order to talk to the board successfully, you have to install the ST-Link drivers. ![]()
