Resolved! STM32L412RB - Programming
Hi, Is there an option to program the STM32L412RB with DFU / Serial interface? I was programming the STM32F407 with DFU and Serial before and now I want to use the STM32L412RB and program it the same way. I can't find any information on the BOOT1 pin...
Cannot wake-up from STOP mode with LPTIM
Greetings, I am having trouble in waking up from Stop mode in STM32U585RIT6 LQFP64 MCU. So I saw the following posts: https://community.st.com/t5/stm32-mcus/troubleshooting-waking-up-from-stop-mode-issues-with-lptim-in/ta-p/745343https://community.st...
Resolved! Question about the speculative accesses
Following this post describing how to disable speculative accesses on external memories range (0x6000 0000 to 0xDFFF FFFF) on Cortex®-M7 processors, I'm wondering if such mechanism should be done to:- memory regions marked as reserved:Source - DTCM /...
B-U585I-IOT02A very high power consumption during active and stop2 modes
Hello, I am trying to implement an edge AI application on the B-U585I-IOT02A board alternating between active mode for inference and stop2 mode. I based the implementation on the PWR_LPMODE_RTC example for the U575 board, I have attached main.c below...

Resolved! Is there a way to store lots of data on a stm32 board?
My company is developing a system that needs to download thousands of images from a computer to an STM32 development board via a local area network. The total size of the images may reach tens of GB (if possible, the data should remain even in the ev...

I am unable to start a PWM signal on my Nucleo board --> I was not able to observe a signal on an oscilloscope.Please see the following code and Cube configurations.1) Is the following code all that is necessary to start a PWM on a channel (given it ...
Resolved! Waking from STOP mode causes hard fault but only when debugging
I have experienced this issue on STM32L4R and STM32U5. If debugging through STOP mode (with DBGMCU_CR_DBG_STOP set), the flash memory occasionally seems to read out garbage as the MCU is coming out of STOP mode. This typically causes the CPU to har...
