I added an -fexceptions flag to the linker script using the Properties menu, but can't find how to remove --specs=nano.specs from the scriptProperties->C/C++ Build->MCU G++ LinkerThe "All options" is grayed out so I can't edit it.Properties->C/C++ Bu...

My program keeps crashing in my uiTask loop, and I figured out the common denominator is a call to portYIELD_WITHIN_API().Here's the relevant code in main. Obviously there are a lot of calls to classes / structs here that aren't shown, but I've sifte...

I've been trying to configure a TIM6 to run at 48kHz, where APB1 is 108MHz, but because the APBDIV > 1, I used PSC = 449, and Period = 9:216,000,000 / ((449+1)*(9+1)) = 48,000And in my timer interrupt, I set a GPIO output pin to toggle. When I probe ...

I'm looking at the "Debugging and diagnosing hard faults" on FreeRTOS' website (https://www.freertos.org/Debugging-Hard-Faults-On-Cortex-M-Microcontrollers.html), and I populated my HardFault_Handler() function and defined prvGetRegistersFromStack()....

I'm trying to test reading data from the ADC DMA buffer, and writing it to the DAC DMA buffer, in one of my tasks.ADC_HandleTypeDef hadc2; ADC_HandleTypeDef hadc3; DMA_HandleTypeDef hdma_adc2; DMA_HandleTypeDef hdma_adc3; DAC_HandleTypeDef hdac; DM...

Ah, yes, that's it. I thought it'd be under linker settings, my mistake

So I just un-commented all the calls to objects in the task, and now the program is no longer crashing. So maybe it is in fact a class issue. I guess I'll keep trying things.

I've changed the code a few times since that thread, but currently SCB->INVSTATE is set."When this bit is set, the PC value stacked for the exception return points to the instruction that attempted the illegal use of the ESPR"What exactly is meant by...

I checked the SCB registers, and it does look like it's a hard fault, even though the call stack and breakpoint don't show this.Unfortunately the call stack doesn't give me much to work with:WWDG_IRQHandler() <signal handler called>() at 0xfffffffd p...

The VECTACTIVE bits are 0x3. Which looks like it's the RTC Wakeup interrupt? I wasn't expecting to need to implement a wakeup routinehttps://www.st.com/resource/en/reference_manual/dm00224583-stm32f76xxx-and-stm32f77xxx-advanced-arm-based-32-bit-mcus...
