I have permanently conected ST- LINK V3 to my STM .My problem occurs when my board is working and i try connect ST-LINK to USB. When connecting ST-LINK reset my STM. This is big problem for me.
Hi, I have designed a custom board with some sensors and a CMWX1ZZABZ-078 chipset as MCU and Lora module. To design the board I have copied the schematic that Murata has in the datasheet of the module, I'm trying to connect the board to the computer ...
I have designed/developed more than 140 microcontroller-based boards utilizing 8, 16 and 32 bit MCU's. I recently designed a board that uses a STM32F765VGT6 MCU. During my initial power-up test, I verified that all of the voltages are in range. Ho...
As the CWD protocol is based on JTAG; Is it possible to debug a non-ST chip with the ST-Link V2? To do step by step code debug? I think in my case to debug code, loaded on a JN5169 (NXP chip based on ARM Risk) Thank you!
Hi,I want to give to a F103 the faculty to program any other F103 in one touch on the blue button... with a known .hex program.only the SWD link between them.User Scenario:The user plug a new F103 (SWDCLK+SWDIO+GND+3V3) to the 'loader' (without any P...
Hi everyone,I a student who is new to the STM32. I've trying to find tutorials specific to the Nucleo-G474REbut I have not found any. Are there any specific tutorials to this board ? And if not what are the best tutorials out there to start learning ...
Hello,For an end of study project, I use a STM32L073RZT6 MCU.I made an STM32 / Breadboard adapter. Like that : Now, I would like to program this MCU. For this, I was given a ST-LINK / V2. I used the MCU and ST LINK datasheet to make the following con...
Hi all!I have developed a PCB with a stm32f4 MCU. The MCU can be programmed through SWD and works well. However, the current consumption of the whole PCB is high (~190 mA at 3.3 V). When I erase the chip, the current consumption becomes 120 mA. Could...
I am trying to connect my stm32f103C8 via usb, when I did this I got the following message "Error in initializing ST-LINK device.Reason: (4) No device found on target".I try to update it with the stm32utility and it doesn't recognize the card.How can...
Hello,Is it possible to connect a target board with a STM32 to a Nucleo-L432KC kit and download the firmware inside the STM32 ? The connector CN2 is only to programm the STM32F103, it's not a connector for the target ?thanks
