Would like to use a STM32L452 MCU with VDD=1.8V but still be able to maintain USB functionality for DFU updates. This device has a separate VDDUSB pin that I would like to power separately (3.3V) from an LDO when VBUS is connected.
As long as the VDDUSB supply is from 3.0V to 3.6V and is the last to be applied and first removed (vs. VDD), there should be no issues?

Why is a single 23-bit value not correctly written to the flash memory when I use 'HAL_FLASH_Program()'?
HelloI've managed to get the 'FLASH_EraseProgram' example program for the Nucleo-F413ZH that comes with 'STM32Cube_FW_F4_V1.25.0' working on a Nucleo-F413ZH board.It erases sectors 2 to 15 and fills them with data - i.e. 0x78563412 that shows up repe...
X-CUBE-CELLULAR on B-U585-IOT02A Hard faults when executing AT+CGMR handler. The SID_CTXT.device_info pointer is NULL when memcpy is called to copy the response into the struct. On L4, the pointer is NULL also but the code continues.
at_modem_signalling.c fRspAnalyze_CGMR() line 1583. In L4 the compiler is v5, on U5 the compiler is v6. It seems the main issue is that the device_info pointer is not initialized before this code executes. CS_get_device_info() is called later after C...
Resolved! STM32L4xx USB Composite Device
Hello everyone, I am making a USB Composite Device according to the article - https://sudonull.com/post/68144-CDC-MSC-USB-Composite-Device-on-STM32-HAL. I use stm32l4xx, instead of the HAL_PCDEx_PMAConfig() functions, I use the HAL_PCDEx_SetTxFiFo()/...
STM32 UART bootloader on brand new chip.
Hi, I have some questions about the STM32 UART bootloader. I've never used this technology, so the questions might be trivial, but I couldn't find detailed information on the internet.Question 1 - In all the tutorials I found, development boards or e...
DFU Mode with L152 / L082
I am developing a project for the L082 (as we have stock of these) but am currently using the L152 discovery board to get things started. This is going well but I thought that I would try the DFU mode to allow easier field software updates. I tried...
Needing help customizing the USB setup on STM32H750 to connect as a "Generic Bulk Device" under the "Universal Serial Bus devices" in the Device Manager.
Switched from another processor to the STM32H750 on updated boards, and trying to keep the PC communication the same so it is seamless (or as seamless as can be) for the user experience. Previous boards connected up to Windows as a Generic Bulk Devic...
STM32H743 system bootloader does not work by USART2
I would like to download code from Raspberry Pi to NUCLEO-H743ZI2 board. On RPi, I use STM32flash app and 2 GPIOs for NUCLEO's NRST & BOOT0. STM32flash generates the signals properly (I see that current STM32 application does not start) and I acquire...
