SystemClock_Config hangs
it seems my project hangs at this line ?if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); }What could be wrong?

Is driver for ST-link v2? digitally signed?
Hello , maybe I post this question to the wrong place...I would like to use ST-LINK/V2, Part number for required Software is "STSW-LINK009".In the description I can read "driver signed for Windows7, Windows8, Windows10".Could someone confirm that thi...
Unexpected oscillation from a GPIO pin STM32L562QEI6
Hello,please see the schematic attached. I observed 2 MHz oscillation (with 1V amplitude) on pin M1 (PA5) when I send a square wave with a period of 2 seconds.The GPIO is connected to that simple circuit, used to generate heat in the resistor.I used ...
Can't get my controller in Low Power mode
Hi,My controller still consumes 360µA in STOP mode, i can't figure out why.Maybe one of the inputs/outputs that leaks current?I have this IO setup the moment i execute STOPPA0-PA5 = External interrups up down edgle no pull up of downPA6 = ADC inputPA...
What's the Best LINK debugger/programmer for DualCore
I've been using Crossworks and J-Link for all of my embedded ST development.I'm starting a new project using STM32H747 and find I can't use my old tools.I am going to use STMCubeIDE for dual core development and would like to know the best debugger/p...
Experiences with Non original STM32F4 processors from China.
Hello everybody, we use STM32F429 processor in our devices. In the current lack of chips, we were forced to order chips from the only supplier who had them in stock, from China. The processor seems to work, but unfortunately it cannot be loaded other...
STM32 programming using ST link V2.
Hi, We are using STM32F407VG MCU for one of the project and for programming we are using ST link V2. The MCU has SWD pinout, when we try to connect the MCU using STM32cube programmer we are getting the below errors,ST-LINK error (DEV_USB_COMM_ERR)Err...
How Debug Works in ST-Link?
Hello, I'm researching the mechanisms of debugging in STM32F407 MCU using several debug probes. I previously used J-Link and I could see the details of the breakpoints in the FPB unit, but when I switched to ST-Link I couldn't see the details of the ...
Resolved! Multiple MCUs are connected via JTAG using a typical JTAG daisy chain connection. All MCUs are already programmed with a FW that uses the JTAG pins for other purposes. Is that still possible to use the JTAG daisy connection to program all MCU at once ?
Hi all,The MCU we will be using is in the STM32U5 Family.The debug probe will be the SEGGER J-Link Base.Best regards,Bastien
Resolved! How GPIO speed is implemented on hardware lvl
Hello! I need to know how GPIO speed control is implemented. Unfortunately, no information was found in the documentation. All that is known is that the signal front is growing faster or slower, but why? I need some hardware schematic or diagram etc....
