Factory OS runtime images are stored in the “Boot Files” directory of the R9 Development installation (see
Quick start guide). The OS runtime image present in the NAND Flash is programmed through the USB
device port connection. Prior to programming an OS runtime, the existing image must be erased. The
procedure to erase the NAND Flash is documented in the Debug Port section.
Once the NAND Flash has been erased, use a standard USB device cable and connect the Type B connector
to the SBC-R9. Connect Type A connector into the host PC.
(See Figure 42.)

In Microsoft Windows 7, the device is recognized as a GPS camera and will typically enumerate as a COM
port. Check the device manager to determine the COM# associated with the device. If prompted with the
New Hardware wizard or the device is not recognized, then install the driver using the following steps (XP
menus shown, but Vista is similar). In the Found New Hardware Wizard, specify "Install from a list or
specific location" and click Next. (See Figure 43.)
