3.1 Setup Details
In order to have access to the UART COM ports for troubleshooting, connect
the USB port of the GM01Q-STMOD board to your computer with a micro
USB cable.
3.1.1 Software Driver Installation
When you plug the USB connector for the first time in your PC, you need to
wait for approximatively one minute, to allow the drivers auto-install on
Windows.
The USB is used to power the board. It also connects the on-board UART-USB
Bridge IC (FTDI® FT4232HL) to provide ACM interfaces (virtual COM) in
order to access the board through UART.
You should see a window similar to Figure 3-1 on page 8 opening.
Figure 3-1: Driver Auto-Install
If, for some reasons, the driver fails to auto-install on Windows, you can
install them manually from www.ftdichip.com, where you can find the FTDI
driver labelled UART/USB.
After the driver installation, please unplug the Test Kit and reboot your PC.
