4. MRK III 2-link box driver installation package.

5. Batch file for flashing the hex file.

6. Batch file for powering up the board.

Before flashing the hex file, install the drivers for the 2-link box on your PC. The

installation instructions are provided in the 2-Link Installation files folder provided within

the Customer_Support_Package.zip file. Follow these steps for flashing:

1. Connect the 2-link box as shown in Figure 18. Find the MDI interface on the board

and connect the ground wire (brown) of the 2-link box to the marked with a white

arrow.

2. Place the hex file, MtGV0-SIGFOX.hex, in the

Customer_Support_Package/OL2385

folder. If the hex file name is different, rename the file to MtGV0-SIGFOX.hex. This is

the name of the file used inside the batch file script.

3. The MRKIIIlink.exe and MRKIIIlink.dll should be present in

Customer_Support_Package folder provided by NXP.

4. Run the OL2385_load_hexfiles.bat batch file to write the hex file software on OL2385.

5. Run the OL2385_powerup_device batch file to power up the device by the 2-link box,

if you do not have any other power supply connected like microcontroller board or

external battery. Otherwise, you can now disconnect the 2link box.

6.1 OL2385-SIGFOX firmware types

Depending on the interface to the OL2385 transceiver, the firmware running on it can be

categorized into the following types:

• SPI based firmware (fully available): This version needs an external MCU connected

to the OL2385 through a 5-wire SPI interface, as previously explained. This is a

standard NXP product and readily available.

• Button press based firmware (under investigation): This version needs a small

application to be written to the OL2385 to enable use of the three buttons provided on
