GPIOA interrupts not arriving when Nucleo F446RE is on external power and ST-LINK is disconnected, GPIOC interrupts arrive fine

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. ...

I intend to use BGA package STM32H735 and H747.I know that support boundary scan JTAG.I am interesting in solder balls joint reliability.Could you recomand a JTAG controller not very expensive.I consider segger JLink EDU.Can JLink EDUversion do such test?

Which is the best stm32 board (nucleo or evaluation) with embedded high performance DAC for sinusoidal signal generation? see next details.

I am looking for a microcontroller board for the following application:Receive a square wave LVDS signal at 1 kHz (more or less) and generate 2 sinusoidal single-ended output with the same frequency of the incoming square wave with the highest resolu...

STM32H753I-EVAL with STM32H743 programming

Hello,Is it possible to upload my firmware on STM32H743BI, using STM32H753I-EVAL board?It doesn't matter?orshould I have to use STM32H743I-EVAL board?Thanks

ST-Link fails due to too high RDP by mistakes. How to initialze to factory defaust if possible.

I came across a fatal trouble, Connecting ST-Link always fails. This was caused unexpected RDP operation in the debug, that may have changed RDP=1. It was observed that 'some' program is always starts even after Reset. In my observation, UART ...
