Hello all,I am using STM32L431 in this project, and I have made a prototyping board for it. However, the MCU will not communicate with the debugger.Below is MCU part of schematic:Only SWDIO and SWCLK are connected to the debugger. The MCU is powere...
I have STM32L4P5CGU6 (48 pin).Pins PB5, PB4, PB3, PA15 are used as SPI1 with another IC which has 3.3V levels.As well as PB6, PB8, PB9 as custom input GPIOs with voltage levels of 3.3V.VDD (pin #9, pin#24, #48) -> 1.8VThey all seem to work fine, howe...
Hello,I have a STM32F429ZI DISCO board and I want to connect it to an external supply but I don't know wich pins I have to connect. Vdd on 3.3V ? or 5V pin ? or 3V pin and 5V pin ? or all of them ?Any one can help me to connect my board ?Thank you !
OpenOCD works, but it's glitchy and has some errors. Before upgrading to STM32CubeIDE 1.8.0, ST-LINK used to work. Upgraded to STM32CubeIDE 1.9.0 and it seems to be failing the same way.The MCU is an STM32L552RCT6.Tried different frequencies for SWD,...
any help with this problem? thanks
hello.A problem occurred when proceeding through an external power source.The first one I am using is the Nucleo F767zi, and the sb111 has been removed.----------------------normal------------------ -----------------------abnormal-------------- Al...
tried to update the ST-LINK with the cubeIDE after that with the ST-LINK TOOL and at the end I tried to install the latest driver with device manager .the STM32U575ZIT is pack fresh .(nucleo)
I'm now using NUCLEO-L476RG. My PC connects to the board by virtual com port? And i try to set a baud rate greater than 115200 but the data received from usart2 is wrong. However, when i set the baud rate less than 115200, it works well.So i wanna a...
HiI have an STM32F769 Discovery board (STM32F769I-DISCO) with STLink onboard.STLink works fine but if I try to run my STM32 application STLink reports the MCU is not detected:========Target no device foundError in initializing ST-LINK device.Reason: ...
Hello, I am making the connections for programming the STM32G0B1KET6 in hardware and came across the boot0 pin sharing the same connection as the SWCLK for serial wire debug (I am using the 32 pin version of this mcu). Just to confirm to program the ...
