The LPC1343 will enumerate on the PC as two devices: 1. A mass storage device used to program the Flash device for the JN5148 2. A virtual COM port connected directly to UART0 on the JN5148 2.4 JN5148 Device The JN5148 circuit is based around the standard JN5148 reference design.
JN5148 High-Power USB Dongle (DR1131) Reference Manual 6 © NXP Laboratories UK 2012 JN-RM-2064 v1.0 2.5 High-Power Front-End The front-end is a Skyworks SE2431L. This means that the dongle can achieve 22dBm output power and Rx sensitivity of -100dBm. The output of the front-end is connected to a printed antenna. 2.6 LNA Bypass If the dongle is used in the presence of very strong signals, such as Wi-Fi, then there will be a performance improvement by switching off the Low-Noise Amplifier (LNA) in the front-end to stop the input stage of the JN5148 device from being overloaded with other signals. The LNA can be bypassed using DIO1 - driving DIO1 low will bypass the LNA. 2.7 LEDs The two LEDs are connected back-to-back between DIOs 16 and 17.
JN5148 High-Power USB Dongle (DR1131) Reference Manual JN-RM-2064 v1.0 © NXP Laboratories UK 2012 7 3 Programming the LPC1343 Device The LPC1343 device is supplied pre-programmed on all USB dongles. You should never need to reprogram the firmware in the LPC1343 device when developing applications for the JN5148 device. If you are producing new USB dongles or are developing new ways to communicate with the JN5148 device (i.e. new HID classes) then the mechanism for reprogramming the LPC1343 is as follows. 1. Insert the USB dongle into the PC with pins 2 and 6 of J4 connected together. 2. Wait up to 30 seconds. The dongle will now appear in Windows Explorer as a mass storage device with the title ‘CRP DISABLD’: 3. Rename your new binary FIRMWARE.BIN. 4. ‘Drag and drop’ or ‘copy and paste’ the new binary file onto the USB dongle. 5. Remove the USB dongle from the PC and re-insert it, this time with J4 pins 2 and 6 not connected together. Two pre-compiled binaries are available in the JN-RD-6034 reference design. These are:  LPC1343_Firmware_0x10.bin: This binary should be used for devices that store their MAC address at address 0x10, such as the JN5148-J01 and JN5142-J01.  LPC1343_Firmware_0x30.bin: This binary should be used for devices that store their MAC address at address 0x30, such as the JN5148-001.
JN5148 High-Power USB Dongle (DR1131) Reference Manual 8 © NXP Laboratories UK 2012 JN-RM-2064 v1.0 4 Programming the JN5148 Device 4.1 Re-programming USB Dongles You can easily re-programme a dongle with another binary file through a USB port of your PC and the LPC1343 device on the dongle. The replacement binary file must be a specially prepared file called FIRMWARE.BIN. When this file is copied onto the mass storage device, the LPC1343 device holds the JN5148 device in reset and then programs the SPI Flash device directly, releasing the reset once programming is complete. The LPC1343 device will also check the MAC address in the SPI Flash device and preserve it though re-programming operations if a new MAC address has not been specified in the new FIRMWARE.BIN file. 4.2 Preparing the Binary File Before a custom application binary file can be programmed into the USB dongle, a utility called jn514x_firmware.exe must be run on the file to strip out a 4-byte header. This utility is provided in the JenNet-IP SDK (JN-SW-4051) and is located as follows: C:/Jennic/Tools/NXP_USBDongle/jn514x_firmware.exe The utility can be run from a bash shell using the following command: /cygdrive/c/Jennic/Tools/NXP_USBDongle/jn514x_firmware.exe with the following options: -f is used to specify the name of the input file -m is used to specify the IEEE/MAC address of the target device (: separated) -c is used to specify the target chip type (in this case, should be JN5148J01) Therefore, the required usage is: .../jn514x_firmware.exe -f <app path/name> -m <MacAddress> -c JN5148J01 4.3 Programming the Dongle This re-programming of the dongle uses a simple ‘drag and drop’ method within Windows Explorer, as follows: 1. Plug the USB dongle into a free USB port of your PC (if an ‘Installing driver’ message is displayed, refer to Section 4.4 below). 2. Open Windows Explorer - the dongle should appear as ‘Jennic_USB’. 3. If the dongle currently contains any files, delete them. 4. Within Windows Explorer, navigate to the new FIRMWARE.BIN file on your PC, then ‘drag and drop’ or ‘copy and paste’ the new binary file onto the USB dongle.

The first time you plug the dongle into a USB port of your PC, an ‘Installing driver’ message appears in the bottom-right corner of the screen. The system will install most of the software required, but will leave the following box: 2. Close the box and go to Start > Control Panel > System > Device Manager. In the Device Manager, you will notice that the VCOM port is accompanied by an exclamation mark: 3. Right-click on the VCOM port and from the context menu select 'Update driver software..' and then select the manual installation method (bottom option). 4. Use the Update Driver Software browser to navigate down to the folder C:\Jennic\Tools\NXP_USBDongle\Drivers and then click Next. The system will now install the software driver.

You can check that the device driver has installed correctly as if it has, the device NXP LPC1343 will appear in the Ports (COM & LPT) section and will appear as a USB mass storage device in the USB Controllers section. Your dongle is now ready to use.
