hi we haveseveral boards in need of the stm32L151C8t6 and we have some stock of the mcu in question the problem is that all the pcbs 'from JLCPCB' have this weird issue were the mcu is stuck and i have to manually poke thenrst pin multiple time for i...
I'm new to STM32 and designing my first STM32F446RE-64 pin PCB. For reference and education, I'm using the Nucleo-64 STM32F446 board, the STMF4 datasheet and the STMF4 getting started with MCU hardware development guide. I have the following questi...
Hi,we have an STM32F27ZI with VDD at 3.6V.We connected by mistake PDR_ON to GND while we drive the NRST with an external voltage monitor as in the picture.reset circuit to NRSTPower upPower downYellow -> 3.6, Purple -> Reset, Green-> PDR_ON In additi...
Hi,I have run the example code STM32Cube_FW_U5_V1.1.1\Projects\B-U585I-IOT02A\Examples\GPIOGPIO_IOToggle_TrustZone and I can no longer connect to the B-U585I-IOT02A board via STM32CubeProgrammer to disable TrustZone. I have the ST-LINK error message ...

Hello.I use STM32G071GBU6, and I designed the VDD voltage to use 1.8V.I have some questions on the board.1. 3.3V GPIO OUTPUT CONTROL- Should I set the GPIO pin of the MCU to open drain and connect it?2. 3.3 Volt UART Communication ( TX,RX)- Shou...

Hello,I would like to use a stlink V2 programmer purchased here 2548 Adafruit Industries LLC | Schede di sviluppo, kit, programmatori | DigiKey with a STM32 microcontroller(STM32G041) and STM32IDE.I am using serial wire debug and connections should b...
The port is showing in device manager and I can update/downgrade the firmware but I cant flash it. I had some similar problem with a bluepill but I put BOOT0 on 1 and erased the chip. After that it worked. I did the same with this board but it tells ...
The MCU STM32F207VCT6 reference schematics used in our design is made exactly in the same as NUCLEO reference design except for the feedback resistor for the 8MHz oscillator; our design doesn't have that resistor. MCU doesn't connect via SWD.*Edited ...
