Hello there,I'm looking for an official STM32 Nucleo-64 development board (probably mb1136) reference schematic diagram. So I can design my own product based on that.I found some schematic on Digikey and Arrow or my team can also do but it would be g...
We are using STM32L476ZGTx. Until recently I was able to program the chip using ST-Link. A few hours back programming failed due to power issue and since then I have been unable to program the controller.The device connects with ST-Link Utility every...
I'm trying to use a ST-LINKv2 to re-program a consumer device that I know has an STM32 of some kind inside (fairly sure it's a STM32L-something). I found four headers on the board that a continuity tester has shown to be Vdd, Vcc, SCLK, and SWDIO.Con...
Hi, i am working on a project where i am using 4 Relays. once i Set any one of the relay the voltage and current should flow to a particular Relay and it should turned on and off. But in my case all the four relays will set and reset . if i turned o...
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...
