iCE40LM4K Sensor Evaluation Kit
Introduction
Thank you for choosing the Lattice iCE40LM4K Sensor Evaluation Kit. This guide describes how to begin using the
iCE40LM4K Sensor Evaluation Kit, an easy-to-use platform for rapidly prototyping system control designs using an
iCE40LM FPGA. Along with the evaluation board and accessories, this kit includes a pre-loaded demo that allows
communication between the iCE40LM4k Sensor Evaluation Kit and a Qualcomm Snapdragon APQ8060A board
(not included in the package and may be purchased from Intrinsyc). The content of this user’s guide includes an
overview of the features of the board and a step by step guide to using the iCE40LM4K Sensor Evaluation Kit with
the Qualcomm Snapdragon APQ8060A.

Flashing System Image and Boot Image to Intrinsyc Dragon Board
Note that this procedure is not required if the Intrinsyc Dragon Board has already been flashed with the system
image and boot image (cd Lightning_Demos_Drop_WITH_APK_INSTALL/Dragonboard_boot_images/).
To flash the system image and boot image to the Intrinsyc Dragon Board:
1. Connect the Intrinsyc Dragon Board USB port to your host system through the OTG (mini-USB).
i. Download and install android-sdk. Android-sdk for Linux and Windows environment at 
http://developer.android.com/sdk/index.html. 

Set <Installation path>/android_sdk/platform-tools/ to the PATH variable.
2. Run the command below in the terminal/command prompt.
#sudo –s

Note: This command is applicable only for Linux machines. For Windows machine administrative permission is
necessary.
3. Reboot the Intrinsyc Dragon Board in fastboot mode.
i. Keep Button Vol / Zoom + pressed on the Intrinsyc Dragon Board during restart.
If the board is already On in adb mode, use the command below for fastboot mode
#adb reboot bootloader
ii. When the Intrinsyc Dragon Board is in FASTBOOT mode, a white screen comes on with only Intrinsyc
name displayed on it.
iii. Execute the command below in the terminal/command prompt to list the fastboot device number and
its name. 
#fastboot devices
The board is now ready to be flashed with boot.img.
4. Enter the command below to flash system image.
#fastboot flash system system.img
If flashing is successful, OKAY and Finished comments are displayed on the terminal.

iCE40LM4K Sensor Evaluation Kit
Troubleshooting
If the Android application does not respond, perform the following procedure:
1. Close the Sensor_Hub_LP3.5k_intrinsyc process running in background.

In the Android menu, go to
Settings > Applications > Manage Applications > Sensor_Hub_LP3.5k_intrinsyc Force Stop
2. Restart the Intrinsyc Dragon Board.
3. Open the Sensor_Hub application from Android menu and application is ready to receive all sensor’s data.
4. If the android application crashes while being opened, it means that the library file has not been copied. 

Run the command below to install the Sensor Hub apk to the Intrinsyc Dragon Board.
#cd Lightning_Demos_Drop_WITH_APK_INSTALL/Sensor_Hub_Demo_Quick_Strart
/Android_Apllication

Note: This step should be performed only if not currently in the
