Qualcomm Hexagon Android Board Configurations

To configure the Hexagon Android Board hardware board, follow the below steps.

Prerequisites

The board must be running on Android OS.
The board must be a Qualcomm Snapdragon processors with Hexagon DSP(adsp/cdsp) support. The DSP processor versions supported are V66,V68,V69,V73 and V75.
The board should have root access.

Note

Copy the sysMon binary on to the target (If not present) from the SDK using the following adb command:

adb root
adb remount
adb push ${HEXAGON_SDK_ROOT}/tools/utils/sysmon/sysMonApp /data/local/tmp/
adb shell chmod 777 /data/local/tmp/sysMonApp

Press Ctrl+E to open the Model Configurations.
Set the Hardware Board to Qualcomm Hexagon Android Board.
The parameter values under Hardware board settings are automatically populated to their default values.

You can optionally adjust these parameters for your particular use case.

Device

ADB interface

Lists the android debug bridge interface for the selected hardware board.

USB - Select USB interface only if you have connected to an USB.
TCP/IP - Select TCP/IP interface only if you have remotely connected hardware board.

Default: USB

Supported interfaces: USB and TCP/IP

IP address

Specify the IP address of the remotely connected hardware board. This parameter is only available when ADB interface is set to TCP/IP.

Default: <empty>

Port

Specify the port number of the remotely connected hardware board. This parameter is only available when ADB interface is set to TCP/IP.

Default: <empty>

Get device information

Get device information provides information of Device id, Processor version, and available cores for the remotely connected hardware board.

Get device information when ADB interface is set to TCP/IP.

Get device information when ADB interface is set to USB.

Device id

Provides the connected device id information. The information gets auto-populated once a device is selected and when you click Get Device Information button.

Default: <empty>

Processor version

Lists the device processor version for the selected hardware board.

Default: V68

Supported versions: V66, V68, V69, V73 and V75.

Processing unit

Select the processing unit for the selected hardware board.

Default: adsp

Supported versions: adsp and cdsp.

Enable HVX

Select to enable the Hexagon Vector eXtension (HVX vector processor). If this parameter is not enabled, the default configuration of the Qualcomm Hexagon Simulator board is Qualcomm Hexagon Library (QHL scalar processor).

To enable this parameter, set Processing unit parameter to cdsp.

Default: off

Supported profilers: off and on

PIL

Execution timeout

Specify the PIL execution timeout.

Default: 30

Build Options

Build action

Default: Build

Build

Press Ctrl+B or click Build.

Generates code from the model.
Compiles and links the code into an executable with libraries.

This option does not load and run the executable on the Qualcomm Hexagon processor.

Disable parallel build

Select to compile the generated code in parallel order for faster build.

on – When you select this option, the support package compiles generated code in a sequential order.
off – When you clear the option, the support package compiles generated code parallely. Parallel execution reduces the time taken to build the model.

Default: off

Clocking

DSP Clock (MHz)

This option is for the CPU clock frequency of the microcontrollers on the target hardware. The DSP clock is dependent on the selection of Hexagon interface.

Default: 300
