The DSP Abstraction Layer (DSPAL) provides a standard interface for porting code to the Hexagon processor.
The DSPAL change log is located here.
See GettingStarted
After installing the development tools, make sure you have your [environment variables set up] https://github.com/ATLFlight/ATLFlightDocs/blob/master/GettingStarted.md#setup-environment-variables).
git clone https://github.com/ATLFlight/dspal
cd dspal
git submodule update --init --recursive
cd test
make
Connect the device via ADB and make sure it can be found.
adb devices
You should see something like:
$ adb devices
List of devices attached
997e5d3a device
Now load the dspal_tester and version_test apps on the device.
make load
This will push dspal_tester and version_test to /home/linaro/ on the device, and it will push libdspal_tester.so, libdspal_tester_skel.so, libversion_test_skel.so and libversion_test.so to /usr/share/data/adsp/ on the device.
To see the program output from the code running on the DSP, you will need to run mini-dm in another terminal.
${HEXAGON_SDK_ROOT}/tools/mini-dm/Linux_Debug/mini-dm
If not found in the above location try this:
${HEXAGON_SDK_ROOT}/tools/debug/mini-dm/Linux_Debug/mini-dm
To run the program:
$ adb shell
# cd /home/linaro
# ./dspal_tester
You should see output on the ADB terminal similar to (if you don't, see the "Troubleshooting" section below):

DspAL some tests skipped.
DspAL tests succeeded.
There is a utility to check the version of the DSP SW.
Connect the Snapdragon Flight board via micro USB connector for ADB.
Then get a shell on the device:
adb shell
# cd /home/linaro
# ./version_test
# exit
Amongst the debug output you should see something like:
version: DSPAL_VERSION_STRING=DSPAL-1.0.1.0001
build date: BUILD_DATE_STRING=Feb 2 2016
build time: BUILD_TIME_STRING=19:10:21
