USART prints junk after initializing the HSE clock (HAL_RCC_ClockConfig)

Hello,I am getting junk printed on the USART after initializing HSE clock. I had USART output at every single line and figured out that up to "HAL_RCC_ClockConfig" everything is ok and junk is printed right after executing this line. Also made sure t...

Why CubeMX use so many memory? I create the blink test from Stepbystep on NUCLEO-L011 with default settings (UART disabled). When I compile the project, it takes 77% of RAM and 33% of Flash.

There is somthings wrong in settings of my CubeMX?There is some optimizzatione that I can do?If I don't use CubeMX ( and so I don't use HAL), there is another libraryes that I can use in order to manage the MCU without managing register ?Thanks.

Stm32g03 series MCU occasionally enter HardFault_Handle() when writing flash

2 Chips with Different i2C Address on same I2c Bus , here how to ensure which i2c data is recieved? If any example for stm32f072 please share . Thanks , Rohit

Tera Term not working with STM32F407VG Board

I have been trying hard to produce a output in TeraTerm & RealTerm using uart2 via GPIO A Pins PA2 & PA3 which are directly connected to St-Linkv2 on my STM2F407VG Disc-1 Board. It just fails to produce anything. I am using STM32Cube IDE and STM32 Cu...

SMT32_L4 non multiplexed asynchronous RAM IS61WV102416BL addressing issues

Hello everyone,For a university Project we are using a STM32L4 MCU together with the  IS61WV102416BL non multiplexed asynchronous SRAM. I followed the Application note which can be found at:https://www.st.com/resource/en/application_note/dm00228015-u...

STM32 application split up

I'm working on an STM32L432KCU microcontroller. I want to develop two applications on the same MCU:An "OTA" app. This would load first. It uses a cellular modem to check for, and download firmware updates, and overwrite the existing application. Othe...

Trap NULL pointer dereference

Hi,We are using STM32H750 for the new product development. The IDE is IAR Embedded Workbench and the RTOS is uC/OS-II.We found that it is OK to dereference NULL pointer on STM32H750. Any way to trap NULL pointer dereference to generate an access vio...
