Free toolchains for STM32VLDISCOVERY
How to program the STM32VLDISCOVERY board? ST does not provide a toolchain themselves, instead there are three different officially supported toolchains available, for which ST has provided simple tutorials. All of the three official toolchains are for Windows, so Linux users have to think of something else. Fortunately, multiple options exist for also Linux users.
Here's an overview of all the tools I'm aware of. First off, I'll explain the easy, official options. These are unfortunately only for Windows users.
Officially promoted toolchains
ST provides example code and documentation for three toolchains: Atollic TrueSTUDIO, IAR Embedded Workbench and Keil MDK-ARM.
Download ST's example firmware package here
User manual for the firmware package
Below are some quick facts & links about the official toolchains.
Atollic TrueSTUDIO (Windows)
This is an Eclipse-based development platform that includes an optimizing C/C++ compiler, editor and a debugger. With the free Lite version, you lose the C++ support, but you get unlimited code size and usage time. If you eventually use the Lite version to design an embedded product, they want you to note it in the user documentation of your product. There is also a 30-day trial version available which has all the functionality of the Professional version. If you use Windows, this toolchain is probably the best & easiest choice to start with. According to a forum post I read, it doesn't work under Wine.

IAR Embedded Workbench (Windows)
The Kickstart edition is a free version of the IAR Embedded Workbench. It's limited to 32kB code size, but otherwise it's fully functional. You have to register it in order to get a license key.

Keil MDK-ARM-Basic (Windows, under Wine in Linux)
There's a free version available of the Keil MDK-ARM-Basic toolchain, but it comes with a 32kB code size restriction. You need to register on the site to get to the download. According to a forum post I read, the Keil toolchain works also in Linux under Wine.

STM32 ST-Link Utility (Windows)
This free program from ST can be used to flash the microcontroller and to read and modify the memory contents on the fly. Unfortunately, it's only for Windows.

Alternative options
Here's a list of alternative programming tools for the discovery. Many Linux ones, also some Windows. Unfortunately, to my knowledge, the built-in ST-Link debugger does not work with Linux. Debugging is possible only through some effort. (Edit: Now ST-Link works under Linux too, see "Captn's missing link")
I have to say that I haven't tried out these options yet... If you have some experience and know better, please comment below!

CooCox tools (Windows)
CooCox offers many free tools suitable for STM32F100RB. Unfortunately they are not compatible with ST-Link, but you can use their free and open CoLink programmer among others. Coocox CoIDE is a new, free and highly-integrated software development environment for ARM cortex M3 and M0 based microcontrollers. CoOS is a free and open realtime operating system for the Cortex-M series. CoFlash is a stand-alone flash programming software that uses their free CoLink programmer. Unfortunately, the software is for Windows only.

Raisonance Ride7 (Windows)
Raisonance Ride7 and RKit-ARM is a complete toolchain for ARM Cortex-M. There are some limitations to the unlicensed software. What the limitations are is not very clear, but at least there's no code size limitations. (Thanks error404)
Download Raisonance Ride7 and RKit-ARM and documentation here
Free Pascal (any OS)
Jeppe at the element14 forums pointed out Free Pascal. He says it's a fun and logical langugage to use, but not entirely finished yet. Still, should probably work for most uses.

Captn's missing link - ST-Link on Linux!
This guy has succeeded in making the ST-Link working under Linux. This means you can finally program the STM32VLDISCOVERY via it's built-in USB programmer under Linux! Quoting texane in the hackaday.com discussion: "an opensource stlink-like standalone software to program the discovery kit is on its way. It is a bit crappy yet (you will have to look inside the source), but it supports both flash and RAM programming plus some other features." Great news!

OK, that's it for now. If you have any other options, ideas or recommendations, please comment!

If you need tutorial for STM32 look here:
ReplyDeletehttp://www.emcu.it/STM32.html#TUTORIAL_and_SW_examples
Eventhough it is still a bit crapy, the following
ReplyDeletecode implements all that is needed to program the
kit directly from the usb port from linux (both flash
and RAM, plus some jtag related features). And it is
opensource, so feel free to contribute.
initial website: http://capitanio.org/mlink/
git repo: git://github.com/texane/stlink.git
hi, just to inform the post on hackaday is not from
ReplyDeletecaptn himself, but from me (texane@gmail.com).
He started the implementation from scratch and
I added the support for the flash access.
I maintain a repository of its source code + the added flash access on github:
git://github.com/texane/stlink.git
Regards,
t.
Whoops, sorry. Fixed it!
ReplyDeleteGreat work for making this possible on Linux!
no problem, that is a shame STMicroelec people
ReplyDeletedid not do it themselves... thanks for sharing
all those info.
There is also Donald Becker's Linux utility https://lists.berlios.de/pipermail/openocd-development/2011-March/018263.html
ReplyDeleteThanks! I added the arm-utilities to the list.
ReplyDeleteFor information, ST-Link on Linux from texane (git://github.com/texane/stlink.git) is now supporting : st-link v1 & v2. Boards STM32 VL, L and F4 can be flashed and debugged with it.
ReplyDeleteYou can also build stlink for Mac OS X http://cu.rious.org/make/getting-stlink-to-work-on-mac-os-x-with-macports/
ReplyDeleteFound this STM32VLDISCOVERY Linux template project for ST-Link: https://github.com/h0rr0rrdrag0n/stm32vldiscovery-linux-template
ReplyDeleteAnd here's a STM32VLDISCOVERY project template tutorial for Windows, using Eclipse and Code Sourcery.

Yet another GNU ARM toolchain: YAGARTO. http://www.yagarto.de/index.html
ReplyDeleteWhat is so hard to understand is that ST like many others want you to pay tax to Micro$oft instead of spending your money on THEIR products and evaluation boards.
ReplyDeleteNow CooCox compatible with ST-Link from the box.
ReplyDeleteI also successfully built basic STM32 applications with tcc (http://tinycc.org), itself built with cross compilation enabled!
ReplyDeleteST is known for long to build good hardware but to be light on "public" support (focusing on close links with big customers), but things are evolving, especially with STM32/STM8 spreading!
This new IDE package looks great: http://www.emblocks.org
ReplyDeleteAnother free package: http://www.emide.org/ comes with IDE, GNU ARM compiler, but needs a J-link debugger.
Haven't tried them yet though...
Also, Wikipedia has now a handy list of toolchains!
