I am trying to use the backup SRAM but get a hard fault when writing to the memory. I have unlocked the backup domain, enabled the backup regulator, and enabled the clock. What other step am I missing? // unlock backup domain HAL_PWR_EnableBkUpAcce...

I have started with the Nx_WebServer demo application which requires the web content files to be loaded onto the SD card ahead of time. I am adapting the project to use a RAM file system instead of the SD card file system. However, I am struggling to...

You are correct. The base timer will get started when started the input capture so forget what I said there.

The interrupt service routine was taking longer to execute than the input capture. So as soon as the interrupt was done there would be another pending and start right back over.Also there is no bounds checking on the array index. The continuous inter...

You need to start the base timer before you start the input capture… if(HAL_TIM_Base_Start_IT(&Input_Handle) != HAL_OK) { Error_Handler(); } if(HAL_TIM_IC_Start_IT(&Input_Handle, TIM_CHANNEL_1) != HAL_OK) { Error_Handler(); }

@waclawek.jan He is using an input presacler of 8 which helps some (432 cycles instead of 54), but I agree with you that this would be a good use case for the DMA if he must use a 2MHz clock. @chai2145 You could try reducing the execution time of the...

Exactly. The bootloader code that STM32CubeMX generates suffers from this same issue. When optimizations are enabled (with AC6 anyway) it works fine. But crashes when using -O0.
