Flashing a build with USB (NXP Bootloader)
Flashing a build via USB (all platforms)
1. Download the MCU Bootloader ( NXP_Kinetis_Bootloader_2.0.0 package ) from the NXP website here - Please note, you will need to click the 'More' link at the foot of the 'Development Software - miscellaneous' listing to see the NXP_Kinetis_Bootloader_2.0.0 package listed.
2. The downloaded SDK file for the module already contains a pre built version of the Tracker project which can be flashed without any need to engage with NXP's MCUXpresso environment, if this is your preference, then proceed to step 6.
The required file can be found in ~/thingstream-client-devkit-module-<version>/tracker/out
3. If you have modified the Tracker project in some way to better suit your needs, you should follow the initial getting started steps on this page to set up your hardware, get the SDKs and configure the MCUXpresso environment.
4. In MCUXpresso, open the 'tracker-<version>' project. In the project explorer view, right click on the 'tracker-<version>' project to open the popup-menu, then select Build configurations > Set active > Release
5. From the main MCUXpresso menu select Project > Clean. Make sure that 'Clean all projects' is selected and then click OK. Once complete, from the main menu select Project > Build All. This will generate tracker-<version>.axf and tracker-<version>.srec in the folder:
thingstream-client-devkit-module-<version>/tracker/Release
6. If you arrive at this point having received a board from a marketing event then proceed to 7a. if you have previously flashed code to your module or if you are replacing an existing Thingstream build then proceed to 7b.
7a.
Place module in bootloader mode by power cycling the board and then press and release button SW1 (circled below):
power off the module and base board by removing the USB cable or switching the USB power to the base board off
power up the module and base board by re-inserting the USB cable or turning the USB power back on
press and then release button SW1 button on the module shown circled in red, below. (NOT the one on the base board)
the led will transition from flashing green, blue, red to not flashing at all
7b.
Place module in bootloader mode by holding SW1 down while you power cycle the boards:
power off the module and base board by removing the USB cable or switching the USB power to the base board off
hold down button SW1 button on the module (NOT the one on the base board) shown circled in red, below.
power up the module and base board by re-inserting the USB cable or turning the USB power back on
release the button SW1
You may see the led cycle through green, blue, red, when you release the button, you should see the LED D1 flash white once to indicate that the module bootloader has been activated

If you need more help or have any questions, please send an email to services-support@u-blox.com.
Now follow the platform-specific instructions below for Windows, Mac or Ubuntu.
Windows
Navigate to the KinetisFlashTool folder in the downloaded bootloader file path (e.g. C:\dev\NXP_Kinetis_Bootloader_2_0_0\bin\Tools\win\KinetisFlashTool) and run KinetisFlashTool
Select USB option which should have settings VID:0x15a2 and PID: 0x0073
In the right Pane, Update / Image File, select the .srec file to be flashed. Look in:
thingstream-client-devkit-module-<version>/tracker/out for the default release build
thingstream-client-devkit-module-<version>/tracker/Release or Logging or Debug for any customised build
Click Update.

It is recommended that when the board is power cycled after flashing it should be plugged via USB into the mains or a power source greater than that offered by a laptop / desktop PC USB port.
When the board is re-powered it will power up in application mode and not bootloader mode and the tracker app will run.
Mac
To flash the .srec file to the board requires a USB setting (0x15a2,0x0073) this needs to be confirmed before flashing in order to ensure success
On a Mac, click on the Apple () Menu in the corner of your screen, choose About this Mac then click the System report button.
Select USB under Hardware menu for a list of USB devices and their addresses
Kinetis Bootloader: should display in the list as per screenshot. If this is not the case then unplug the board and repeat step 3.
Select the .srec file to be flashed. Look in:
thingstream-client-devkit-module-<version>/tracker/out for the default release build
thingstream-client-devkit-module-<version>/tracker/Release or Logging or Debug for any customised build
In terminal Navigate to NXP_Kinetis_Bootloader_2_0_0/bin/Tools/blhost/mac

Ubuntu
To flash the .srec file to the board requires a USB setting (0x15a2,0x0073) this needs to be confirmed before flashing in order to ensure success.
On your ubuntu instance type lsusb
this will list the USB devices and will include an entry for 'Freescale Semiconductor, Inc.'
(e.g. Bus 003 Device 003: ID 15a2:0073 Freescale Semiconductor, Inc.)
Select USB under Hardware menu for a list of USB devices and their addresses
Select the .srec file to be flashed. Look in:
thingstream-client-devkit-module-<version>/tracker/out for the default release build
thingstream-client-devkit-module-<version>/tracker/Release or Logging or Debug for any customised build
In terminal Navigate to NXP_Kinetis_Bootloader_2_0_0/bin/Tools/blhost/linux/amd64 or i386 depending on your hardware.
Ensure that the file blhost contained within the folder is executable, if not 'chmod +x blhost'.
You may well need to be logged in as su.
