X-CUBE-AI: External memory corruption during inference on STM32U5

Hello,We are experiencing corruption of our external IS66WVO32M8 PSRAM while executing x-cube-ai generated code on target device STM32U585AIIxQ. This corruption happens consistently when running the model (i.e. running the ai_*_run() generated functi...

Resolved! Matmul operation is converted to MCU target Convolution

Hello. I am currently attempting to execute a MatMul operation on an NPU. I have implemented a simple TFLite file with a MatMul operation, as shown in the image below.When converting the model using ST Edge AI, I observed that Matmul operator is mapp...

Resolved! PyTorch to STM32H7: Is there a simpler workflow?

Hello,I recently deployed multiple individual PyTorch models onto my STM32H7A3ZI-Q. My workflow ended up being:1. Convert from .pt -> .onnx -> .tf -> .tflite (quantized)2. Build an X-CUBE-AI project via CubeMX3. Swap models in same project using ST E...

How do I run an RNN series model file?

HelloI'm considering running an LSTM(RNN-based model) model file, on the STN32N657 NPU.However, I understand that the NPU is CNN-based and therefore cannot run on it.Is there a way to run an LSTM model file on the NPU?I understand that theoretically,...
