Sample scripts have been provided in the R9 Development installation to automate the process of writing
a complete OS runtime to the device. The script is configured to target a device attached to COM49 by
default. This can be modified simply by editing the comport variable in the “NAND Program.bat” batch file.
Once the batch file has been updated to reflect your system configuration, simply double-click the batch
file to begin the programming process. The process will take a few minutes. (See Figure 45).

Programming NAND (COM17)
Once programming has completed, cycle device power and the OS runtime should boot. (See Figure 46.)

Programming complete
As previously mentioned, the process of programming the NAND Flash first erases all content from the NAND
Flash. This includes the unique MAC address assigned to your device at the factory. The “finalize.exe” tool is
provided in the “Boot Files” directory of the R9 Development installation. Finalize is a command line utility that
accepts a MAC address in dashed notation (00-0A-0B-16-12-34). The application should be executed on the
device after reprogramming the NAND Flash to reassign the MAC address. Once the application has been
executed, the setting is applied upon device restart and persists.
