Hello ST Community. I have a STM32H755ZI-Q Nucleo board that I seemed to have blown up the STM32 part. I suspect this because the board is getting an overcurrent condition. But have some questions so I can better understand what may have caused this....
Hi i want to enable Power module (Generally PWR EN) on which bus i can enable this bit in can of NUCLEO-H723ZGas for reference manual is used RM0468 Also if you find this please give me link to that data sheet and secion number as i can not find it i...
Hi, My board is acting strange. - When I use the USB to power the board (jumper JP3 on U5V) the led LD5 turns red ( the board draws more than 500mA). So I power the board with external power supply (5V and JP3 on E5V) but even if i'm able to flash th...
Hello, I have designed a circuit using the STM32F747XIH6, but I am unable to connect and flash the code using ST-Link. I have checked all the connections, and the NRST pin has a pull-up resistor and measures 3.3V. The 25MHz clock signal appears corre...
I just received a NUCLEO-H503RB dev board, and while attempting to use the GPIO_IOToggle example program to test out the board, I could not run the debugger due to the error "ST-Link not detected." I went back to my NUCLEO-H7S3L8 board, it now receiv...
I'm using an ST-Link V2 to stream (over ITM) code coverage data from an STM32G4 via GDB Server on a PC.This works fine most of the time (for many days), but the data stream sometimes drops some of the data. Adding a delay between calls to ITM_SendCha...
Hello, Im looking forward to get started with STM32 MCUs, planning to begin with a Discovery kit. Have few questions, before I get going.- Kindly suggest a Discovery kit, which has been there for sometime and is general purpose.- For code deve...
Hello all, How can I make a vias for the WLCSP156 to connect my internal layers from my PCB with WLCSP156 pads? If the pad diameter is only 0.220 mm in WLCSP156 , and the minimum hole for the vias at the factories is 0.15 mm (with ring is 0.25 mm tha...
I have an STM32 Nucleo-F446RE, which comes with an integrated ST-LINK/V2-1 debugger. I would like to use this ST-LINK to program an external STM32 MCU that does not have a development board.I checked the Nucleo schematics, and I see that ST-LINK/V2-1...
I'm using the STM32H753ZI Nucleo board with USB_OTG_FS communication,and I have enabled VBUS_SENSING. I would like to detect when the physical connection is lost,but I am not sure how to do it.Could you kindly provide any reference materials or guid...
