Qprintf example

This example illustrates how to use the Qualcomm printf library (qprintf) located under $HEXAGON_SDK_ROOT/libs/qprintf.

The example demonstrates how the library displays the contents of scalar and vector registers from assembly and provides various options for displaying HVX_Vector contents from C.

Refer to the Feature Matrix for example support and to know the DSP architecture on the target.

Using the walkthrough script

The walkthrough script qprintf_example_walkthrough.py automates the steps of signing the device, building, pushing and running the qprintf_ example. You can run the walkthrough script with the dry-run (-DR) option to display all the commands that the script would execute without actually running them.

Review the generic setup and walkthrough_scripts instructions to learn more about setting up your device and using the walkthrough script.
