I have a Nucleo H745ZI-Q board powered from the CN1 STLINK USB port. I am observing bursts of noise on the 5V line. The noise is 150mV p-p, burst of about 6 (80us) pulses, every 18ms.The H745 is idle and the debugger is not active.I have tried severa...
There is a 4-pin connector for ST-Link, but not populated. What debug tool can be used with ST-Link-V3E connector (micro USB)?
When I tried to debug my STM32F303RE nucleo board with Truestudio , I get this messages from console:When I get this message , I was working on EXTI interrupts at register levelSTMicroelectronics ST-LINK GDB server. Version 5.1.0 Copyright (c) 2018, ...
I performed the following steps:1) Set JP7 to STLK2) Connect USB -> Demo starts correctly3) Flash a simple self-written code (sets LED to state of user-button) via OpenOCD -> ST-Link works4) Flash a second self-written code (sets both LED to state of...
hiI'm using stm32f101vbt6 by st-linkv2 programmer.after few times programming my micro i get this message : no target connected. so my debugger can't recognize microcontroller.i checked every connection and it was ok I tried j-link programmer but j-l...
Hello, thereI was not able to use the NJTRST (PB4) pin as a general GPIO input pin. I googled and other people having the same issue using the macro: __HAL_AFIO_REMAP_SWJ_NONJTRST()to remap the NJTRST pin. Yet, this macro is not available for the STM...
Hi,I have made a custom board that features a STM32F469NI MCU coupled with AS4C4M32S SDRAM.Following are the SDRAM timing and register set information:hsdram1.Instance = FMC_SDRAM_DEVICE; /* hsdram1.Init */ hsdram1.Init.SDBank = FMC_SDRAM_BANK1; ...
Hello!I guess most of the problem is described in the title. I made a board using a STM32F767 chip. It works well when attached to STLink, can be debugged and programmed, communicates well by SPI and so on. But once detached from STLink, it doesn't b...
I destroyed the MCU(STM32H743ZIT6) and ST-Link V3.But I don't know what happen.When I connect the ST-LinkV3 with the Laptop, then the ST-Link and MCU was broken.So, if you know what happen, please teach for me.
