SPI Slave NSS input not consistent

So I'm having this weird bug I can't seem to figure out.I'm trying to connect two stm32f4 discovery boards through SPI.The master is sending out a SS signal I want to use to synchronize with the slave.However for some reason before I send out a messa...

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...

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...

How do I check the MCU availability and production plans? Looks like a shortage of STM32F303CCT6 and no information of future availability plans. When does the MCU go obsolete? Is there a roadmap? Regards, AJ

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 ....
