Hi All!

I've just started using the EFM32 microcontroller familiy form Energy Micro.

I'm currently using the IAR compiler, but that one is rather costly if I want to use it commersialy. And my budget might not allow that for the next year or so.

Has anyone set up gcc to compile for this achitecture? I know there is support for ARM CORTEX-M3 in gcc, but I have no ifra where to begin in order to set it up.

I'm using gcc (WinAVR) for AVR 8-bit controllers in other projects.

Any good pointers?


Best Regards
Bernt

You need to have a working GCC compiler for your host(x86 PC) and source code for the GCC compiler tool chain.
additionaly to automate you may need a cross compiler generator like Crosstool-NG.

now using Crosstool-NG you can create a cross compiler for your target architecture. if you like then you may also create a native compiler for your target too. but it is not needed.

AN0023 Eclipse Toolchain
This application note will show you how to set up a simple project in Eclipse, how to generate the code and finally debugging the code on an EFM32 microcontroller.

You will need a "Gecko Starter Kit" (STK) or "Gecko Development Kit" (DK) and the following tools:
• Eclipse IDE for C/C++ Developers.
• CodeSourcery Sourcery G++ Lite, the GNU toolsuite containing gcc compiler/linker and gdb debugger.
• Zylin Embedded CDT plugin, makes debugging of embedded targets with Eclipse easier.
• Eclipse Embedded Systems Register View plugin (EmbSys). Eclipse view of peripheral registers of all Energy Micro EFM32 parts.
• SEGGER J-Link software and documentation pack which contains SEGGER's J-Link GDB Server. The GDB server interfaces the gdb debugger to the target debug probe for EFM32 parts.
• Energy Micro's EFM32 energyAware Software. It contains the SW examples and energyAware Commander which is used to program the flash memory of EFM32 part
