Resolved! STM32G4 Performance at 1.8V
Would STM32G4 performance gets effected if runs at lower voltage (1.8V)? Can the core clock run at max 170MHZ or it will run lower speed?

Resolved! STM Nucleo L552ZE_Q LPUART configuration
I am trying to configure the LPUART on my board, but appear to be getting nowhere. I've already configured the PLL to run at 110 MHz, and I changed the appropriate registers (`SW`) to use PLL as the system clock. I've tried flashing the board with Ze...
STM32L433RCT VDDUSB and BOOT0 pin for firmware updates via USB
I am using the NUCLEO-L433RC-P development board and in the process of designing my own PCB.I would like to be able to update firmware via USB, but need to make sure my PCB design allows for this.Currently I have VDDUSB connected to 3.3V, but thinkin...
Resolved! jlink fails to connect to stm32n6
Hey All,I hope you can help me. I'm trying to bring up my new board, which contains a STM32N657IO. Attached are the schematics. You can assume the 5V supply is working(it is after a few bodge wires). My problem is as follows. I'm trying to connect to...

Hello Friends,I am Using STM32F303 MCU for my FULL Speed USB communication board. Used interrupt transfer.Board is going to use in Noisy Industrial environment.So , Planned to use Shielded USB cable with EMI Chokes ( Both Side ).Cable Length is 1.8 ...
Resolved! Unexpected results with iterative use of STM32H5 CRC unit
Hi,I am trying to use the STM32H5 CRC unit via HAL to calculate a CRC32 (ISO-HDLC) over multiple chunks.This works correctly via:hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE; hcrc.Init.DefaultInitValueUse = DEFAULT_...
can't erase correct Flash Bank when attempting to switch from Bank2 to Bank1
Title shortened from:"With the STM32U545RE, unable to erase the correct Flash Bank, using HAL_FLASHEx_Erase(), when attempting to switch from Bank2 to Bank1".Please keep the title short. Testing is done with the Nulceo-U545RE-Q board having 512KB Fla...
Clarification on IWDG Reset Behavior: UM3150 vs RM0481 (STM32H5 Series)
I came across a discrepancy between two ST documents regarding the behavior of an IWDG reset on STM32H5 devices, and I’d like clarification on what exactly is reset when an IWDG event occurs.Document 1: UM3150 Rev 2 – STM32H5 Safety Manual, Table 9 (...
Resolved! STM32G030K6T6 Timer 16 seems to use SYSCLK instead of PCLK
Hi all.I have a small problem understanding the timer 16 of the STM32G030K6T6 microcontroller. According to the data sheet, it should use the TIMPCLK clock, which corresponds to the PCLK clock.My system clock is supplied by the HSI (SYSCLK = 16 MHz)....
STM32F446RET6 Virtual Com Port
I’m working on a custom board with an STM32F446REt6 and a USB Type-C 2.0 connector (GCT SB4105-GF-A). I haven’t implemented any external pull-up on the D+ and D- lines, but on the CC1 and CC2 pins I have 5.1k pulldown resistors. I managed to load the...
