ProgSTM32 : Flash firmware in stm32 microcontrollers

In STM32 (ARM Cortex-M based) microcontrollers, a default bootloader is programmed into system memory by ST Microelectronics. This bootloader can communicate to host computer through USART port using a well defined protocol.

progstm32 sdk: Java applications can implement functionality to upgrade firmware in their stm32 based product by using the APIs provided by this SDK. It implements complete protocol to communicate with factory bootloader in stm32 microcontroller. GUI based applications can use this in their 'Help->Upgrade' menu option, where if user selects this option new firmware gets flashed in the end user product. It saves time to market, application development cost and helps engineers to focus more on business use cases.

progstm32 app: It is a commandline application based on progstm32 SDK. It can be used as an independent flashing utility for stm32 microcontrollers. More information about options and usage can be obtained from manpage.

The progstm32 uses SerialPundit SDK for serial port communication, which is a separate project and can be found here.

Features

• Erase, read and write firmware or arbitrary data in storage
• No restriction on addresses and address length
• Read bootloader ID, protocol version, ROM-programmed data, product ID
• Handle device specific quirks internally
• Enter/exit bootloader mode using DTR/RTS signals
• Robust error handling
• Enable/disable read/write protection of storage
• Resume communication with stm32 if required
• Convert intel hex firmware to plain binary
• Fully documented (javadocs,manpage) and tested
• Programmatically trigger system reset

Build and Installation

To build and install progstm32 sdk and application run the following commands.

$ ./configure
$ make
$ sudo make install

In case you have custom installation of Java, set JAVA_HOME as shown below and then run ./configure script:

$ export JAVA_HOME=/home/a/packages/jdk1.8.0_31

If debug build is desired pass D=1 as option to make during build. Debug builds generates extra logs when communicating with stm32 microcontroller.

$ make D=1

If you want to build only sdk run command given below. Prebuilt sdk jar file is present in release folder.

$ make uartsdk

If you want to build javadocs run command:

$ make javadoc

Documentation

• Manpage can be read using standard command for unix systems.

$ man progstm32

• Javadocs are found in documentation/uartsdk-javadocs folder.
