I am having an issue with the firmware update on STM32F427 MCU by using the ST-Link utility tool and Keil debugging functionality. When I reload the new program on MCU, sporadically flash erase step marking few sectors are write-protected. I used the...
Hi. Where can I find the schematic of the STM32F429I-DISC1 development board. I have not found it in any document provided by ST.Thanks.

Hi I would like to know what heat sink is compatible with the STM32H753I EVAL 2FG evaluation board.It seems there are holes outlined around the MCU where the heat sink can be applied?Best regards,Luke
Hi, I am using the STM32 Nucleo F446RE board. I have accidentely changed the PA13 pin, which is assigned to the debugger to a GPIO output pin, which resulted in my debugger not working and now I can't load any new code on the STM. How do I change bac...
Hello. i am using stm32L0 family.i have ST-Link V3. its working fine with st link utility tool. i can connect using cli command with normal mode. so the issue is Connect under Reset. CLI command is not working if i connect in Connect under Re...
I've designed a custom PCB incorporating STM32F401RE. I've received the first batch of PCB and attempted to program one, but STM32CubeIDE raises the error line as in the title ("No device found on target").I've kept the design (see image) as close as...
I'm just learning to read and use schematics and I found that while physically the MCU (STM32F407VG on my STM32F4 Discovery board) is marked U4 as the part number on the PCB, the schematic (Section "STM32Fx" of "MB997-F407VGT6-D01_Schematic.pdf") sho...
Hi,In my application running on a Nucleo F446RE I notice that EXTI interrupts from GPIOA are not arriving in the EXTI15_10_IRQHandler() when the Nucleo board is connected to external power on E5V, JP5 on E5V and the ST-LINK is disconnected from USB. ...
