STM32F7 (Nucleo F767I) Ethernet Linkup Problem

Hello,I have generated sample project with latest STM32Cube for NUCLEO F767I and have ethernet linkup problems... (don't work)I have generated the same sample for NUCLEO F429ZI and working fine ! STM32F779I-EVAL (but here ist other MII PHY ) and work...

I2C clock not generated on SCK pin

I was working on i2c using STM32L476 nucleo board.I used stm32cube to make a code for keil.When I generated the code and programmed it in the board i found that the oscilloscope was not showing any clock on it .Oscilloscope's channel1 was connected t...

How to recover bricked STM32F051R8T6(STM32F0 discovery)?

My device is STM32F051R8T6, the same used in STM32F0 discovery board.I was tweaking with the clock configuration section to try different clock configurations like HSI and HSE, etc. I could erase, flash and verify the program successfully, however th...

USB Stall Behavior (CubeMx, CDC)

Hi,I'm struggling to integrate a USB interface into a bootloader. The microcontroller always stalls the USB communication. To find the cause of this problem I have set up a simple project to compare the USB transfers and came to a point where I can't...

Stm32f103c8t6 TIM1, where 1ms is mandatory. I need a Ticker of 0.01ms or 0.001ms, to be able to discount with the time of the routines to increment / show the time in a serial display / 32bits. Bravos

STM32F072 GPIO Register inaccesible

Posted on July 15, 2018 at 23:44Hello STM Community, I'm trying to evaluate the STM as a viable alternative to NXP MCUs. However, I have encountered a very early issue with accessing GPIO registers for a simple custom blinky program. I'm working in ...

STM32L4 nucleo board programming problem

I have a STM32L476RG nucleo board.Recently when I tried to program it using keil I found some error messages and I was unable to program it.I found that LD3 LED is glowing .Initially when the board was programmable it was not glowing.I am attaching e...

Steps to have external SDRAM work properly!

I'm editing linker and startup files according to the example "FMC_SDRAM_DataMemory" but i con not access SDRAM. In example, it has only 2 regions as FLASH and RAM but we have 5 regions as FLASH, DTCMRAM, SRAM1, SRAM2 and MEMORY_B1. Also how can an i...

STM32F051R8 works when in debug mode and not in normal power mode

The device used to work fine even when not in debug mode. However, after some tweaks in the clock configuration, the device all of a sudden stopped working even the simplest of the program like toggling a GPIO pin. The same program works well fine in...
