My STM32H533VE works as PD Sink.We connected CC1/CC2 with DBCC1/DBCC2 (as AN5225), STM32 cannot power up with a USB PD adapter. The adapter supplies power for ~20ms then stops the supplying.If I remove the long time initialization code (LSE initializ...
Hello,I am using NUCLEO-H755ZI-Q (STM32H755) and I am observing a reproducible boot issue related to high system clock frequency.1. Hardware / EnvironmentBoard: NUCLEO-H755ZI-QMCU: STM32H755Power supply: USB (on-board)Debugger: ST-LINK (Connect under...
The Errata sheet for STM32G030x6/x8, ES0486 - Rev 6, states in chapter 2.2.9:After connecting the debug interface and until the device power-down, the boot source upon reset or wakeup from a low-power mode is determined by the PA14-BOOT0 pin level be...
I designed a board that uses a STM32H750 with a USB3300-EZK that has stopped communicating over USB. It's been having intermittent issues for the last day or so (sometimes I'd need to power cycle the board before it would show up, but then it would w...
On the STM32N6, half the ram is attached to this NPU RAM on it's own bus. Are there any downsides to using this ram for non neural net applications. Use case I would like to use the NPU ram for just frame buffers. From what i can tell the memo...
In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...
Hi,we are trying to get a 800x800 display to work with the STM32U5G9VJT6Q, using either RGB888 or RGB565 in Video Mode (Burst).According to what we read it is definitely possible. Did we miss something?Could someone please confirm that is definitely ...
Hello.How can we enable brown out for this processor and the brown out voltage?Thank you.
Hey all, I have been debugging a nasty issue that I have been having over the last couple of days. I am using the STM32n657I0 MCU. The issue that I observed were random crashes in my code. Luckily the problem was well reproducible. What I observed wa...
I have been working on an IoT project using STMicroelectronics' STM32 microcontrollers, and I have encountered a unique challenge around power management. My system needs to run on minimal power to ensure long battery life in remote applications, but...
