No device found on target with external ST-Link to Nucleo-F070RB

Good afternoonBefore doing a final PCB design I wanted to test external ST-Link connectivity to the F070 on my Nucleo-F070RB board..So therefore I:Removed SB12 and SB15 (disconnect nRST and SWO)Removed jumpers on CN2Attached external ST-LinkST-Link P...

ST Link Utility is unable to detect the board. STN32f407vgt6. It throws No ST - Link detected. I have Windows 8.1, Keil u5, and latest ST -Link STSW LINK004 DOWNLOADED AS WELL. Even Disk Manager methods did not work. Tried hard for that. Pls do help.

Is my jumpers in right position. Pls do help. Thanks

Why STM32H747I-DISCO ref design using two different CADs?

Hi, there! :) I've just downloaded the STM32H747I-DISCO MB1248 board design files(https://www.st.com/resource/en/board_manufacturing_specification/mb1248_bdp.zip) I found that the schematics is an Altium Designer Project, but layout is an Allegro brd...

problem with stm32G070 connection

Hello, at the beginning I had STM32G070 (brand new), from the beginning I had a problem with it, ST-LINK utility was connecting with uC, but after a while disconnects it. I was looking in the settings unfortunately I found nothing. Oddly enough, once...

Undocumented Pullup on Pin PB4/JNRST

Hi,as I see it here in my test PCB, the pin PB4 (JNRST for JTAG interface) seems to have an internal weak pullup during reset (I assume 40kOhm as NRST - an external 10kOhm will pull this pin down, but 100kOhm pull down does NOT work...).It is luckily...

Where can I get technical info about stencil thickness and openings for UFQFPN packeges?

Hello. I am building an application and planning on using the STLINK-V3SET to program and debug, but I can not find any reference which describes what pins to connect for the VCP_TX and RX pins from the programming header to the MCU.

I believe that I connect the following:T_SWDIO -> PA13T_SWCLK -> PA14T_NRST -> NRSTBut which pins on the MCU do I connect for the virtual comport? VCP_TX -> PA2 or PA9VCP_RX -> PA3 or PA10Also, SWO is not avaliable on the Cortex M0+? so is not conne...

Olimex STM32-P407 (STM32F407ZGT6): No device found on target (using ST-LINK/V2)

Hi everyone,I purchased several boards from Olimex (STM32-E407, STM32-P405, STM32-P407) and I am using the ST toolchain (STM32CubeMX, STM32CubeIDE, ST-LINK/V2, STM32 ST-LINK Utility). The purpose is just to blink a LED.For the boards STM32-E407 and S...

STM32 DISCOVERY DISC-1 LOSES PROGRAM AFTER POWER OFF?

Dear all!!I have a STM32 DISCOVERY DISC-1 and I have a problem. I created .hex file by KeilC and I programed this board by STM32 ST-LINK Utility and everthing seem be OK. But, when I turned off power and after that I turned on, board was not run. I c...
