Why do I get an "failed to download Segment[0]" error when using a custom external loader in STM32CubeProgrammer version 2.7.0 or higher? The trace shown below is only an example, some values may vary, but the main point is that an error is raised (a...

I am using your NanoEdge AI Studio Software for classification and I am looking at the FFTs displayed in the signals segment after collecting data.How, specifically are these FFTs generated from the raw data ? Also, what the units on the axis are as ...

Hi,From what I see it seems that frame buffer gets corrupted or at least the reading of the frame buffer content is incorrect.This may be linked to a clocking issue, what is the FMC clock in your project?According to datasheet (DS12535_DS10915_DS1091...

Hi,I think the MPU is still to blame, could you try the following settings for the external RAM ? MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER3; MPU_InitStruct.BaseAddress = 0xC0000000; MPU_InitStruct.Size = MP...

HI,I both agree and disagree There is indeed information on external RAM or FLASH memories in the CubeMX but not on their purpose.External RAM could be used to store frame buffers or maybe application copied at runtime, the MPU configuration would t...

Hi,Your MPU configuration misses the most important region, the one that disables all accesses to external memories : MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.BaseAddress = 0x00; MPU_InitStruct.Size = MPU_REGION_SIZE_4GB; MPU_InitStr...

Hi,For random hardfaults on a Cortex-M7-based MCU using external memories, the very first thing to check is the memory protection unit, this may be due to unexpected speculative accesses.In short you should define a global MPU region disabling all ac...
