BUSIF1 ERR: 0x20 and Epoch Controller ERROR interrupt: EC_IRQ = 0x0000000a with STM32N6570-DK

[Firmin]

Hello everyone,

I am encountering errors when running Semantic Segmentation, Object Detection, and Pose Estimation models on my STM32N6570-DK board using STM32 Model Zoo Services. Here are the details of my setup and the errors I am facing:

Hardware and Versions:

• Board: STM32N6570-DK
• Models: Semantic Segmentation, Object Detection, Pose Estimation
• Tools: STM32Cube.AI 4.0.0, GCC 14.3.1, HAL 1.3.0, STMCubeIDE 2.1.1

I followed the README instructions from the STM32 Model Zoo Services repository to test the mentioned models. I compiled and flashed the firmware onto the STM32N6570-DK board.

Errors Encountered:

Bus interface interrupt
BUSIF0 ERR: 0x0
BUSIF1 ERR: 0x20
Epoch Controller ERROR interrupt: EC_IRQ = 0x0000000a
Epoch Controller opcode counter: 0x00000000
Epoch Controller label: 0x00000000
ATON_STD_IRQHandler()@871: irqs=0xlx
assertion "0" failed: file "[...]/stm32ai-modelzoo-services/application_code/.../ll_aton_runtime.c", line 875, function: __LL_ATON_RT_IrqErr

Questions:

1. What could be causing the BUSIF1 ERR: 0x20 error?
2. Why is the Epoch Controller generating an error interrupt with EC_IRQ = 0x0000000a?
3. Are there specific configurations for Semantic Segmentation, Object Detection, and Pose Estimation models that could resolve these errors?
4. Are there known code examples or fixes for these errors?

Thank you in advance for your help!
