How to get a H755ZI to run 400 MHz from the ST-Link USB Power? ACTVOSRDY flag never gets set after configuring power for PWR_DIRECT_SMPS_SUPPLY.

Hi all, I've created a few projects on a H755ZI-Q that run just fine at the default 16 MHz (I think), but I'm having trouble getting it to clock at 400 MHz. I've tried this for all of my projects which include, the Cube examples (H745), the CubeIDE N...

STM32F103 random reset

Hello, we have made a 2 layer board for a STM32f103, and apparently it works fine but we get a random resets now and then. When that occurs there is a 1 in the Bit 27 PORRSTF: POR/PDR reset flag and Bit 26 PINRSTF: PIN reset flag of the Control/statu...

Why is my uart rx not working though my tx is working ?

I am doing a barebones uart demo on NUCLEO-F303K8. I am using uart 2 through the vcp (stlink virtual com port).I see my transmit working. But I have nothing on receive. I have attached my project. Its done in STM32CubeIDE.Here is the main separately/...

How to reset cpu after ending debug session with st-link?

I am facing a problem after I finish the debug session. Once I try to reset the cpu via the reset button or manually resetting the CPU via the ST-Link Utility the program does not start. The only way to start the program again is to click agian the d...

What exactly does a full chip erase through ST-Link do? Would it brick my board?

I've been having trouble connecting my board through the STM IDE. I've decided that I want to in a sense 'factory reset' the board. Would a full chip erase do this or would it ruin my board?

How do you test the VCP uart port of the nucleo 32 board in linux?

I am using STm32 nucleo -32 F303K8 board. I see it has the ability to re-route uart2 to st-link to give a virtual com port. However, I see nothing on it. How do I validate the vcom port on linux cube ide? Is there a demo code?

With stlink-v3 attached to stm32h753 eval2, software does not get interrupts from uart1

Hello: I have an stm32h753 eval2 board. I recently purchased an stlink-v3set. Connecting to board using CN9, everything works: programming, CPU information, memory dump, etc. However, embedded instrumentation shows that uart1 is asserting a tx empty ...

I am using Nucleo-g431rb, I want to program and debug it with isolation from computer, I am trying to use st-link/V2 isol, but no success, because I can't find the connector for CN10. What is the way to debug it with isolation.

STM32F070 + ST-LINK v2 SWD connection issues

I've made a custom design of a board with an STM32F070C6B6. When powering on the board and connecting a genuine ST-LINK v2 programmer, the connection fails halfway through the setup.What i've tried (i'm on linux):1) Via STM32CubeProgrammer:Connect un...
