Error in initializing ST-LINK device. Reason: No device found on target.
Hello.I'm having problems to program an STM32G474-NUCLEO Board with an external STLINK programmer. I'm using the STDC14 on-board connector and following the instructions given in the the board user manual. However, I get the error: "Error in initiali...
Resolved! why is LD3 (red power led) working with 3V3 input on NUCLEO-F072RB ?
I have this board (revision C-04) with ST-LINK removed (PCB cut off), so the power 3V3 is supplied from CN7. It works fine, but the red power led (LD3) also works. LD3 is, I think, connected to the 5V net, and 5V to 3V3 regulator should not be workin...
Resolved! Fake Stlinks reaching me trough "legit" distributors. Which STCubeProgrammer version shall we use?
My company just purchased 10x new STLINKS in WINSOURCE.We are having trouble using them with newer versions of STCubeProgrammer(v.2.10.0),they work fine with the old STlinkUtility.I am also unable to upgrade the Fake STlink: The BOX seems legit: The...
Nucleo-64-P unexisting pins
I have a NUCLEO-L452RE-P, on the box and on the user manual (UM2206) it show that PD2 is on CN5.4 and PC5 is on CN6.6. But the STM32L452RET6P doesn't have those pins (PD2 and PC5). To what are connected CN5.4 and CN6.6 ?

Hello,I was using my ST-Link/V2 ISOL, to reflash some units, but after an update with the ST link updater my programmer suddenly not recognize the target board.I tried to reflash with different versions but it says that is corrupted. Is the ST link u...
STEVAL-ESC001V1 Board Failure
I bought two STEVAL-ESC001V1 a few years ago with the purpose of 1) studying the hardware architecture to make my own drone ESC, and 2) lear how to program it.After 2.5 years of learning (this is part time on top of working a 40-72 hour work week) an...
Unicleo not detecting my board
I am using STM32 Nucleo F401RE board with X-NUCLEO-IKS02A1. UNICLEO-GUI is not recognizing my board saying no board is connected where as I can see it is connected to my computer as it is listed in devices connected. Please help me in resolving this...
Resolved! STM32F4 Discovery stops connecting via ST-LINK with my end-of-degree project
I'm working on my end-of-degree project using an STM32F407 Discovery board. I have been working with it the last couple of months with no problems, doing the pin configuration with STM32CubeMX and developing the program in ARM Keil uVision 5.Yesterda...
Systick Delay
I was trying to make a hardware delay using STM32 general purpose timers or Systick timer, But I did not get any source (using HAL Library). How to achieve in STM32L4P5-DK.
