MicroSecond Delay in FreeRTOS
I am dealing with an I2C lockup issue where the I2C bus is locked up periodically and I need to toggle the SCL pin to free up the bus. To test my theory and make sure that the fix works I just used an osDelay(1) call. I know this is a 1ms delay but...
Resolved! STM32G03x bootloader nonresponsive after errant UART data
Good day,I have stumbled upon an issue with my device's bootloader that seems to be inconsistent with the ST documentation. I have an STM32G031K8T6. USART1 RX and TX are connected to an RS-232 transceiver, which is then connected to my host PC using ...
LED toggle example not working when flashing .bin from STM Cube programmer.
Hi team,I am using example code GPIO_IOToggle. which is working fine.1. Tried to use below changes in .ld file as below and that also works fine when we dump code form STMCubeIDE.MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 32K FLAS...
Resolved! STM32G0 internal temperature invalid readout
Hello,For some reason I'm unable to get valid readout of internal MCU temperature. Maybe someone have an ide why this might be happening? System is running on STM32G0B0 MCU. I init ADC over HAL generated code and enable only internal inputs (`ADC_CHA...
Resolved! STM32 Learning Path
Dear Team,I am completely new to Embedded systems.I am an analog design engineer.Decided to start my embedded learning with STM32.I bought a nucleo-64 board.If you don't mind could you please guide me how do I start. I saw many training materials in...
Issue with PC10 Pin on STM32F407ZGT6 – No Clock Signal or GPIO Output Observed
Hello Team,We are facing an issue with the STM32F407ZGT6 microcontroller, specifically with the PC10 pin.Our primary objective is to use PC10 as a clock output pin for SPI communication. However, we observed that the expected clock pulses are not bei...
STM32F103RET7 in boot mode
Hi,Can short circuit between near pins (not GND and VCCO) cause damage to STM32F103RET7 ?Thank you.
STM32U575 System Bootloader SPI MISO issue
I am evaluating using SPI and ST's internal System Bootloader for a 2 processor application.To that end, I am attempting to attempt to read in the bootloader via SPI on an STLink V3.I am successfully able to do so for a NUCLEO-L496ZG, but fails for a...
Cannot get STM32F446 into USB DFU mode to upload new firmware
I am trying to get my STM32F446RE (using STM32CubeIde) into USB DFU mode via firmware rather than using the RST and BOOT0 inputs which are going to switches on the board. I know this is doable but for some reason it is not working for mewhenever I go...
