I wrote a code for stm32h745, masking the M4 core, and debugged it for two weeks without any problems per se, but yesterday, I realized that I could download the code, but in debug, I noticed that the data in RAM changes, and I didn't make any change...
Hi, I was looking at the GPIO on the STLink3 PWR and trying to find some logic analyzer but i dont find any. Someone know if that gpio are able to do logic analyzer and if yes, a software to do that ? Thanks in advance,
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...
