[Pulko Mandy] got his hands on the new STM32 F3 Discovery board. He's a fan of the open source tools just like we are, so he posted a guide covering the use of an open source toolchain with the F3 hardware (http://pulkomandy.tk/_/_Electronique/_Discovering%20the%20STM32F3%20Discovery) .

This board was just announced earlier this month (http://hackaday.com/2012/09/12/stm32-f3-discovery-dev-board-includes-some-extras/) but there is already support for it in OpenOCD. It's not all that different from the F4 board, which we would think made the process a bit easier. [Pulko] is using the Sourcery CodeBench Lite toolchain, which works for pretty much all of the ARM chips out there. It is GCC based and comes with GDB for debugging (along with all the other tools you would expect). He did created his own Linker script and startup code. These are crucial for ARM so it's nice that he provided them for us. He finishes up the guide by showing how OpenOCD can be used to flash the code to the chip and how it works with the debugger.
