What about Vref+??As I am not using any Battery, I have decided to connect Vbat directly to VDD, is that correct?OSC32 will not be used in my app, will it be possible for to leave it open?
HiI am using STM32CUBEIDE on macOS. Until now I used my ST-Link v2 via SWD with no problems. I have recently upgraded to an ST-Link v3 MINI and implemented the STDC14 connector on my custom pcbs. The pinout is according to the datasheet (the pins on ...
According to the manual UM1956 I can power my Nucleo-L432K board using 7-12V on VIN.So I attached a 9V block to VIN and GND. It did not work, and all that happened was that I started to smell and got hot. It looks like the capacitor C25 was the compo...
I want to copy-paste ST-Link implementation from a Nucleo or Discovery board to my customer board with STM32H7 processor. This way, the board will have one USB connector to use for programming, debugging, upgrading, and finally, for serial communicat...
I join the schematic of my board to the question. I am unable to connect my custom board, the error message on STM32CubeProgrammer is "Not STM32 target found" even it detects the supply voltage. The VDD required for the MCU is 1.8V and I connect all ...
I am in the process of designing a new controller for a product and the only processors that seem available in any quantity are the -P versions. The datasheet isn't clear for these if the SMPS is optional and you can just use the internal LDO, or if ...

Hi, I've come across a few of these issues namely here but I haven't found a fix for my issue yet. I have a custom PCB based on the STM32H745ZIT6 chip which I wired up to be powered using the LDO power supply. However, I'm running into two problems a...
Hello,As the questions says, I'm having difficulty programming a Nucleo-F334R8 board directly via the PA13 and PA14 SWD pins. After removing the jumpers on the built-in ST-link (CN2) I have connected the external ST link directly to the SWD, reset, g...
