The voltage reference buffer (VREFBUF) seems to control what happens with the Vref+ pin, as described in this from the Reference Manual:Table 225. VREF buffer modesENVR HIZ VREF buffer configuration0 0VREFBUF buffer OFF:– VREF+ pin pulled-down to VSS...
Hi All,I'm looking for advices about boards/components to use for eMMC prototyping.I have got a NUCLEO-H743ZI board, but it seems that there is no shield board for eMMC, and that a solution would be to use SD/MMC card breakout + eMMC dongle.Could one...
I know about optimizers and I've been debugging MCUs for many decades. But this behavior is just too weird and difficult to deal with...I'm using Atollic TrueSTUDIO 9.3.0. When I debug my code and single step through the C source code, the highlighte...
Hello Everybody,i am trying to use LPUART1 on the NUCLEO board. I attsched an oscilloscope probe on the TX pin and tried to send a simple "Hello world\n". But I don't get any signal from the pin. The data is correct transmitted in TDR register.Does a...
I'm using an STM32F105R8T6 and Cube. I've searched and searched and can NOT find any actual documentation on the CAN interface. Yes, there are a couple words in the STM32F105 datasheet, and a brief mention in the Cube's getting started doc. But th...
Using STM32F437 (internal flash 2MBytes).I have a boot application located in sectors 0 - 5 (up to 256KB), and another application located in sectors 6-10 (in linker script I allow up to sector 10 which means up to 640KB, but the binary itself takes ...
Hello,i disable the interuppt after its execution is it allowed?void EXTI4_IRQHandler(void) { // Clear interrupt __HAL_GPIO_EXTI_CLEAR_IT(SYNC_UC_PIN); // call function function();// the function enables an other interrupt of the same pri...
I am using an STM32L010k8 with HAL driver version 1.11.2, when I erase a single flash page at address 0x08004000, the very first call to function FLASH_WaitForLastOperation within HAL_FLASHEx_Erase fails because the OPTVERR bit in FLASH_SR register i...
Hi experts,We have created a project on WICED 43xx_Wi-Fi sdk for STM32F412 MCU+43438 wlan chip.We have connected st-link V2 debugger to the EVB and we could see "STM32 STLink" in windows Device Manager.When we used openOCD to flash debugger to EVB, ...
I got two these STM32H750 boards. Wired up a ST-LINK, and one of them works fine.But the second one is not accessible by debugger.Following is output of CubeIDE debugger:STMicroelectronics ST-LINK GDB server. Version 5.3.2 Copyright (c) 2019, STMicro...
