RMII GPIO state after HAL_ETH_Init()
Hi,we have a PHY with several bootstraps. Some of them are shared with the RMII from a STM32H753 (see image below, controller is on the left).A FreeRTOS+TCP network stack is used, which, when rebooted, first does some low level inits with HAL_ETH_Ini...
Resolved! JTAG and UART connectivity
Hello,We working on custom board. We using this controller STM32745IIkx. In JTAG we connect the USART1 port, but there is pin mapping issue, so I am unable to use USART1.So instead of UASART1 can I use USART2.I am sharing its schematic THE VCP_TX and...
Hi, I bought a Nucleo STM32F401RE board. Yeasterday the board was working fine in dimming led in A0 pin which was configured in PWM mode. Now I can't reprogram the board. See details for error message. PS. I'm a total beginner with microcontrollers

Resolved! Low Power Reset Circuit
Hello, Could anybody please look at the circuit, and if it is correct.I am not sure if C5 is necessary to be there.Thank you.
ST-LINK V3 bricked by STM32CubdeIDE v1.8.0 ?
I fired up CubeIDE again after a while, it updated from v1.4 or so to 1.8 now.When I was about to debug, it offered to update the firmware of my ST-Link V3 SET.It claimed that was successful.When I then wanted to debug, it claims there is no target.I...
I create a PCB with stm32F411 and i obtain: "Can not connect to target" with st-LINK Utility
Hello,For a project, I created a PCB with an STM32F411 using a 10pin JTAG port for SWD programming.I tried to connect my card using the ST LINK V2 box and the ST Link utility software but I get the following error:The st link works because I can prog...
My STM32F302C8T6 only runs the program when the code is loaded. If I reset it or power up, it does not run.
Maybe is a hardware problem since the microcontroller is on a custom board I designed. The problem is the following: The microcontroller only runs the program the moment I load the code, if I reset it or power up the board after a power-off it does n...
Resolved! SMPS with/without LDO comparison
I'm trying to understand the benefits/tradeoffs of the "Direct SMPS supply" and "SMPS supplies LDO" options for the STM327H (red and blue options in the attached figure). Since the LDO adds an extra source of power loss, and the SMPS can supply all d...
Resolved! How to send commands from PC to Nulceo board over ST-Link USB interface (UART)?
Hello everyoneI'm using a Nucleo board, specifically the L031K6. I'm used to sending UART messages from the board to the PC via the ST-Link USB interface. In this project I wanted to do the other direction going from the PC up to the card over the sa...
