How to update my project with a new version of ST Edge AI Core?
for STM32 target, based on ST Edge AI Core Technology 2.2.0
r1.0
Context
This document presents an easy scheme to migrate a project that was written using an old version of STEdgeAI (and its outputs) to a newer version of the tool. This page is specific to projects written for using the ST Neural-ART runtime stack and using the NPU.
The issues faced when re-generating a network.c
file
with a newer version of STEdgeAI are leading to compilation
errors/bad behaviours:
- The generated code is expecting with a newer version of the ST
Neural-ART runtime stack (i.e. it might use new functions, or expect
new behaviours from functions)
- The generated code raises a compiler error if an old version of ST Neural-ART runtime stack is used.
- The generated code is aligned with a newer version of the NetworkRuntime library (i.e. it might expect new behaviours, new API, etc…)
How to migrate
Update the ST Neural-Art runtime software stack
In a similar way, the generated .c
file must be
linked with correct version of ST Neural-ART runtime software
stack (or the compilation will eventually fail with an
error).
The software stack is shipped with STEdgeAI installation in
Middlewares/ST/AI/Npu/ll_aton
. When migrating a project
written with an old version of STEdgeAI, those files should be
replaced by the newer ones in the project.
Summary
- Update the library with the new one in
Middlewares/ST/AI/Lib/<toolchain>/ARMCortexM55
- Update the library headers with the new ones in
Middlewares/ST/AI/Inc/
- Update the Neural-Art runtime software stack with the new one in
Middlewares/ST/AI/Npu/ll_aton
