External Clock for STM32F303RE Nucleo board?

Hello, I'm wonder if the F303RE Nucleo board can be configured to use an external 16MHz TCXO. If so, where can I find documentation on how to configure.Thanks in advance,Dave

Resolved! [SOLVED] HAL _ERROR while trying to program FLASH on STM32F411RE device

Hi,I'm writing a bootloader, the application binary is read from a SD card connected via SDIO and will be written into the SECTOR 2 of the micro controller (starts at 0x8008000 == APP_ADDRESS), the bootloader is stored in SECTOR 0 and SECTOR 1, start...

Program execution gets to void _exit (int status). I am unable to prevent that or find what line causes this to happen.

So somehow through my chain of execution I end up herevoid _exit (int status){ _kill(status, -1); while (1) {} /* Make sure we hang here */}From disassembly it seems that the functions preceeding it areITM_SendChar()and before thatHAL_CAN_Rx...

UART flasher FLASH LOADER DEMONSTRATOR, version 2.8 does not support STM32F730R8

I just received my new boards with STM32F730R8.I have always done UART flashing (*.hex file) that worked great on all other devices (STM32F1xx).But it does not work with STM32F730R8.Here I do not have the abilty to flash with JTAG.The latest FLASH LO...

Stm32L486 ADC3_CCR

Hi,As for the STM32L486, it have 3 ADCs. Is There only 1 ADC common registers ADCx_CCR (x=1,2,3) for all or individual for each ADCx?In IAR IDR Arm8.32.2, the SFR setup information states that it is only one ADC_ CCR for both 3 (atached picture). Thu...
