hard fault when calling SBC_CleanDCache
I had some wrong bytes when transferring data over SPI, so I tried to clean the DCache. But I get a hard fault if I do this:I'm using the NUCLEO-H723ZG board.

QSPI memory mapped mode reads 0xFFFFFFFF everywhere
Hi everyone,I have followed the tutorial from ST to set the external loader :https://www.youtube.com/watch?v=XqCq0xtQmbIhttps://github.com/STMicroelectronics/stm32-external-loader/tree/contribHere's my HW config :I use the same QSPI (MX25L51245G) tha...
Hi all, I'm trying to configure my NUCLEO-H745ZI RAM as Device mass storage, i followed some tutoriels showing how to do this application with CubeMX and Keil IDE but its not working for me. I write my code only in "usbd_storage_if.c" file.
The code compile, load it to flash memory and enter debug mode to run the program.When i connect the usb connector present on the board to test if the computer will detect it as an usb device mass storage, nothing happen ! Can someone help with this ...
Unable to use PC14-OSC32-IN pin in NUCLEO-L152 Board
HI, i am new to STM32 controllers. i am using STM32L151RCT6 MCU in STM cube IDEJust i am trying to use PC14-OSC32_IN pin as input for external IRQ for falling edge configuration ..I not got the proper result , so just i configured that GPIO as input...
Resolved! How to wake MCU from sleep by USART event
I'm learning STM32 by a NUCLEO-L053R8 board. I want to put device to sleep (not LP Sleep, Stop or Standby) and wake it by either an interrupt or an event.int main() { // Clock and peripherals init // UART init (baud rate, GPIO, etc. are...
How to measure the resources (run time / memory consumed) by having part of the code block in external memory encrypted (while using OTFDEC in L5 controller).
I am using STM32L562VE controller. I have configured OTFDEC with a portion of my code encrypted. Is there any way with which I can measure the run time and memory consumed promptly eventhough the code switches back and forth between internal flash an...

Positive injection on FT pin of unpowered device
Hello, Thanks for the great support . I have a doubt regarding FT pin of the STM32F407x microcontroller . Will the microcontroller gets damaged if 5V is applied when it is unpowered ?in the datasheet Table 12. Current characteristics of section 5.2 ....
Resolved! Timer interrupt flag behavior in encoder mode
I have an STM32G474, but this encoder/timer behavior is likely similar for other MCUs. I have the timer set up in quadrature encoder mode on channels 1 and 2 and I'm using input capture on channel 3. This is tied to the encoder index so that it will ...
