Stm32 Serial Flash Loader
Flash Loader The STM32 Flash loader demonstrator (FLASHER-STM32) is a free software PC utility from STMicroelectronics, which runs on PC and communicates through the RS232 with the STM32 system memory bootloader.
STM32™ and STM8™ Flash loader demonstrator Introduction The purpose of this document is to describe the STMicroelectronics STM32™ and STM8™ Flash loader demonstrator application that was developed to illustrate the System memory boot loader capabilities. This document details the prerequested hardware and software environments, as well as. How can the answer be improved? STM32 Serial Boot loader September 20, 2016 I am working with a generic STM32F103 board. This board has a serial bootloader on board, that runs on serial port 1. (There are 3 serial ports, numbered 1, 2, and 3). This port is on pins PA9 (tx1) and PA10 (rx1). Naturally the signals are at 3.3 volt levels. Mar 13, 2015 Program STM32F4 with UART. By tilz0R September 17, 2014. Flash loader demonstrator select compiled file. Correct written data will be shown with window like my below.

Nov 15, 2016 What we do next is download Flash Loader Demonstrator which is a tool to interact with bootloader. Install it and launch. Install it and launch. You will see screen where you will be able to select USART parameters. If you are still having issues then it could just be that you have bricked your device so you will need to try a firmware recovery by shorting the boot pins while flashing, or using the STM32 Flash Loader tool to recover the firmware (search this site for a guide on how to do that if you are stuck).
I have an STM32F102 microcontroller and I want to program it via the Serial Port.
While there is a flasher available for windows, I want to do it on a Linux Machine. I tried doing it with this script
I have set BOOT0 = 1 and BOOT1 = 0, restarted the microcontroller. But it does not work. I get the following output

Here are a few tips:
Connect serial cable before resetting / powering up the board. Otherwise some transients can mess the serial bootloader up.
Make sure you are using a TTL level USB-to-serial converter instead of a RS-232 cable. RS-232 has inverted level, and worse still, its -15V to 15V voltage range can burn your STM32.
Make sure RX and TX are connected correctly. /weatherby-regency-serial-numbers.html.
Try using
stm32flashinstead.Most STM32's serial bootloader does not support baud rate higher than 115200 as I remember. The bootloader can detect baud rate automatically, the one I usually use is 57600. best website building apps for mac
Some of these chips are being shipped with locked bootloaders. You will need to use STM32 Flash loader demonstrator to remove the protection. Windows only unfortunately but once it is unlocked you can use any machine.

[2015-12] upstream moved to: http://sourceforge.net/p/stm32flash/code/ci/master/tree/ You'll probably want to use that, as this version is outdated.

stm32flash 0.4 was released 2014-10-04 and is available at https://releases.stm32flash.googlecode.com/git/stm32flash-0.4.tar.gz
The 0.4 version is the work of Antonio Borneo and includes support for programming over I2C. See the included I2C.txt for more information. The code has been refactored to make it easier to add other transports.
Features
Serial Flash Memory
- UART and I2C transports supported
- device identification
- write to flash/ram
- read from flash/ram
- auto-detect Intel HEX or raw binary input format with option to force binary
- flash from binary file
- save flash to binary file
- verify & retry up to N times on failed writes
- start execution at specified address
- software reset the device when finished if -R is specified
- resume already initialized connection (for when reset fails, UART only)
- GPIO signalling to enter bootloader mode (hardware dependent)
Usage
See the included manual page for up-to-date, complete usage instructions.
