problem arising while connecting more than one Relay
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...
Nucleo H745ZI-Q drawing current spikes from USB power port - producing noisy 5V
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...
Resolved! what debug tool can be used with stm32h747i-disco board?
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)?
Resolved! Error in initializing ST-Link device. Reason: (-1) Unknown. Please check power and cabling to target.
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, ...
Resolved! I got two STM32H735 Discovery kits (STM32H735G-DK) and broke them somehow by connecting both via USB at the same time. A) What causes these problems and what can be done to avoid them? B) What can be done to revive the boards?
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...
after few times programming debugger can't recognize microcontroller(stm32f101vbt6)
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...
Resolved! NJTRST (PB4) pin for stm32l431
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...
Can both target board & ST-Link be powered by USB from the same PC?
Hi, I'm a "rookie" and I've got an STM32F407VET6 board and an STLINK/V2, and I seem to understand both are to be powered via USB; my question is:Would connecting them to the same PC give rise to a conflict, electrical or otherwise ?Thank you !
STM32F469 with AS4C4M32S SDRAM only able to write first byte.
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; ...
Custom board works normally when attached to STlink but does not boot in standalone.
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...
