I apologize for I am new at learning bootloader and I am trying to create a custom bootloader for stm32f103 custom dev board. First, I just want to know how can create a compatible binary file to be flashed at existing bootloader.https://github.com/s...
I am using this dev board: NUCLEO-F411RE for developing SPI communication protocol considering it as a SLAVE device. My firmware will receive data over SPI sent by Host machine and acts on it.I have following requirement:How to transmit data packets ...
As described in RM0444I understand my virgin device (STM32G030C6T6) should to connect via UART using STM32CubeProgrammer but as shown I'm not able to establish the first transaction (byte 0x7F reception and answer)I've checked my custom board hardwar...
Hi,While working with RTC smooth calibration on a STM32G070 part, I noticed two strange things:1st strange thing: When RTC_OUT pin is only driven with the battery backup (no main power) I got 512.18 Hz; however, when the main power is restablished, t...
Hello,I was able to update F429 using boot-0 and CubeProg tool via USB. But requirement was to update without boot-0 pin. Please suggest alternatives for update from USB.Also wanted to know: I tried changing boot-0 to do DFU, using SW and HW reset bu...
Hi! I am new in electronics, but I am trying to design my PCB using STM32F469IIT6. I did a similar project before using a simple atmega168, but the STM32 seems way more complex. I wonder what the minimum of hardware connection is I need to be able to...
Hello, I want to ask what is necessary for implementation of 32.768khz RTC XTAL to STM32F411CEU6?In AN3060 I saw in chapter 3, fig6 that external load caps are not needed because they are implemented in STM32 MCU. Then I checked STM32F411CEU6 datashe...
I am trying to figure out how to DFU a STM32G070CB, but finding the available documentation utterly useless.. According to this document : AN2606 "STM32 microcontroller system memory boot mode", my chip STM32G070 uses "Pattern 11":#1. I know what the...
I've been getting some weird hard faults on an STM32U073RCT, which I've tracked down to the following conditions- In stop mode, waiting on an interrupt.- Debugging, with debug in stop mode enabled.- Interrupts are disabled.- An RTC interrupt occurs.W...
Hello ST Community,I am working on an OTA (Over-The-Air) update implementation for an STM32L072 series microcontroller which has 192kb flash memory. In my setup, I have divided the flash memory into three regions: bootloader (starting at 0x08000000),...
