Hi all,I'm using STM32f048t6.I would like to load code using DFU bootloader for virgin device using HSI48.The boot configuration is correct using BOOT0 pin.Is it possible or I need an HSE?Note: after a jtag programming the USB works correctly. At har...
Hi folks,I've got an F429ZI board which works fine, I've run a few samples and I've had zephyr applications running on it no problem. What I now want to do is set up my own small project using the bare minimum of third-party code to begin. I used Cub...
According to the STM32H745xI/G datasheet, the 64MHz HSI is accurate to +/- 0.3 MHz around room temperature, so +/- 0.5%.During testing, I noticed about 10-20% of my UART characters were getting dropped. I then looked at the signal on a scope and noti...
Hi, I am using STM32L452 Controller and I would like to use LSI for RTC which is not an accurate clock source.I referenced the following manual and adjusted the pre-scaler as 2.8 RTC prescaler adjustment with LSI measurements - page 23https://www.st...
Hi,I'm pretty sure it can be done but I would like confirmation.I would like to start with my own bootloader that runs wit HSI clock. It have to properly configure an external PLL source (by I2C peripheral). Only when that chip is locked, I would lik...
Hello.I am in the process of power on my custom board. Right now I'm trying to get the USB to work but I'm stuck and don't know what to do next.I use USB midleware from CubeMX 6.1.2The moment I have everything configured and run the interrupts I get ...

My SysClock is 200 MHz, AHB Prescaler=1.I want to slow down some timer to filter glitches from external input.But when APB2 peripheral clock is set lower than 50 MHzthe Ethernet DMA does not send any data: no ARP, UDP or TCP.Even when ABP2 timer cloc...
Hi All, Calling HAL_DeInit() causes the STM32H7 micro to reset when it executes __HAL_RCC_AHB3_FORCE_RESET();#define __HAL_RCC_AHB3_FORCE_RESET() (RCC->AHB3RSTR=0xFFFFFFFFU) HAL_StatusTypeDef HAL_DeInit(void) { /* Reset of all peripherals */ _...
HiI'm using a Nucleo-144 with a STM32F767ZI.I have included in my project FreeRTOS and FreeRTOS-IP although that may not be related with the problem, since the crash happens before reaching the initialisation of FreeRTOS.My problem seems to be that H...
