unable to debugg Hardfault error on STM32F412ZG
Hello community,I am trying to write time critical code which involves an STM32f412ZG Nucleo 144 board and a RPi communicating over SPI protocol. I have an IMU sensor communicating to STM32 board via I2C interface. I have 3 tasks, which function as ...
IWDG and CPU Registers
I am working on STM32H7 (Cortex-M7) and using IWDG for monitoring. I am wondering if there is a way to record Cortex-M7 CPU registers (General Purpose (Rx), SP, LR and PC) when IWDG runs out. Either before or after the reset.I understand the RCC regi...
Resolved! How to control STM32H7 QSPI Chip Select?
Hi,I am working on interfacing IS25LP128 128Mbit QSPI Flash with STM32H743 Nucleo board. I am running into problem with how the QSPI controller is driving the NCS line. The flash requires that the chip select remains low between command and data read...

Best method for returning to STOP Mode after Interrupt (STM32L0)
Hello,So I have a project which uses STOP mode with RTC+EINT pins for wakeup. However I have a situation where I want one of the interrupts to not wake up the device- just set a flag and return to STOP mode. I know there is HAL_PWR_EnableSleepOnExit(...
Data Acquisition of STM32F7 ADC DMA
Hello,On my custom-designed PCB, I use STM32F767 ADC for acquisitIon analog signal input in DMA mode. My method is collecting data that running the code in Keil IDE debug mode and then export the converted digital values in a .txt file with a .ini fu...
I am using the STM CubeIDE with a Nucleo L476RG dev board. When I first generated a project I was able to download it to the card and debug. then for some reason I started getting an error saying the arm-none-eabi-gdb.exe has stopped working.
I am able to open an example project and debug that without issues. I have tried regenerating my project, generating a new project, and even reinstalling the tool and generating a new project, but I still get the same error on debugging. I can still ...
