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
I'm referring to USB hardware and PCB guidelines using STM32 MCUs (AN4879)and to USB 2.0 specification. MCU is STM32H755In case when Embedded pull-up resistor on USB_DP line, USB 2.0 OTG HS controller with embedded on-chip HS PHYs and mode = device m...
Hi, i have a question about this. Normally we use F0 series and BOOT0 pin must be connected to GND via 10K Ohm. So, BOOT0 pin were apart. But now, BOOT0 pin and SWCLK pin is same. I created a new schematic and I connected BOOT0/SWCLK to GND via 10K ...
Unfortunately I have already designed my PCB and am now hoping that I just forgot to set a jumper or whatever, but I could not find anything about it in the User Manual. Maybe someone can measure on his or her board to see whether I am mistaken.
Hello,I want to program (first time) an STM32F042K6 with STLINK-V3SET using SWD.When I try to "connect" with STM32CubeProgrammer, I get these informations : "Error : No STM32 target found!". Here is a screen :The connections are : I tried to run the ...
