Programming the ST10F27X embedded Flash
using the ST10FLASHER tool
Introduction
This document summarizes the different steps needed to program the internal Flash memory of the
ST10F27x using the ST10Flasher tool.
The required steps to load a binary file (Intel Binary or Motorola S-Record files) on the ST10F27x
embedded flash will be described.
A HEX file will be provided within an archived file as an example.

This section describes the steps required for programming the ST10F27x embedded Flash
using the ST10Flasher.
To use this document, the ST10Flasher must be already installed on the development host.
For more details on ST10Flasher installation, refer to the readme.txt file included in the
ST10Flasher tool package.
1.1 Starting ST10Flasher
ST10Flasher runs on a PC connected to the ST10F27x target microcontroller via an RS232
interface.
● Enter the standard bootstrap mode by forcing P0L.4 to 0 and P0L.5 to 1
● Reset the ST10
● Select Start -> Programs -> ST10-Flasher-2.4
ST10Flasher starts and the following window appears:

1.2 Communication set up
If the bootstrap loader is OFF or the ST10 is not reset and you start ST10Flasher tool, you will
be unable to program the ST10F27x internal flash and error messages will appear in the status
window :
In this case:
● Enter the bootstrap loader mode
● Reset the ST10
● When loading the monitor, by clicking Reload Monitor icon, the tool performs an auto-
device detection. The device is then displayed in the interface indicating that you are
connected to e.g ST10F276.
If the status window shows other error messages, check that the file "startup.ini" in the selected
application directory corresponds to the application parameters, especially for the parameters
COMPORTet BAUDRATE. Their default delivery settings are:
COMPORT = COM1
BAUDRATE = 9600,N,8,1
