WinARM is a collection of GNU and other tools to develop software for the ARM-family of controllers/processors on MS-Windows-hosts. Unlike other collections WinARM does not depend on a cygwin or mingw-environment. All needed tools are in the distribution-package. WinARM has been tested with Philips LPC2106, Philips LPC2129, Philips LPC2138, Philips LPC2148 and Atmel AT91SAM7S64, AT91SAM7S256, AT91RM9200 ARM7TDMI(-S) controllers (the list is based on own tests and user feedback). The gnu-toolchain and the supplied tools should work with all microcontrollers based on ARM(-TDMI/Thumb etc.) architecture. WinARM has been made in the spirit of WinAVR which is a collection for Atmel AVR 8bit-Controllers.

WinARM includes in Version 20060606:

  • GNU-C/C++-Compiler (cross compiler/linker/assembler arm-elf-*) Version 4.1.1 incl. stdlib3. Compiled from the FSF-Sources The configuration supports ARM-Mode, Thumb-Mode and Mixed(ARM/Thumb)-Mode, little/big-endian and floating point-emulation
  • GNU-Binutils Version Version CVS 20060606 FSF-Sources
  • newlib Version 1.14.0 (build for reentrant syscalls)
  • newlib-lpc Rel.5a (reentrant syscalls for newlib and Philips LPCs)
  • GNU-Utils to support the compiler/linker (make, sh etc. from the mingw-project)
  • ARM header-files (register-defintions) from and others
  • Example applications with full source-code, makefiles, linker-scripts and startup-code for Philips LPC2000, ADuC7k and Atmel AT91SAM7 ARM7TDMI controllers. More Examples on my ARM-Projects pages.
  • Programmers Notepad Editor Version
  • The lpc21isp in-system-programming-software for Philips LPC2xxx and the Analog Devices ADUC 70xx family by Martin Maurer. Included Versions: 1.31 and 1.37(BETA)
  • Bray Terminal by Vlado Brajer
  • Insight-GDB 6.5.50-20060517 - Win32-Native from
  • gdb (command-line without Insight) GNU gdb from Codesourcery
  • Setup-Exe of Macraigor's OCDRemote (Wigger-gdb interface, Ver. 2.16)
  • Open On-Chip debugger (OpenOCD, SVN Version 65) made by Dominic Rath, update available further down.
  • H-JTAG (Ver. 0.2.1 beta 20060402) made by "twentyone"
  • J-Link gdb-Server V1.0 from the gnuarm yahoo-group

Planned extensions:

  • Installer

User-Forum: A support-forum for WinARM/arm-elf-gcc and the example-projects. You are invited to visit this forum and ask questions or help others.

Download by right-click->save as, please download only one of the archives either the zip or the self-extracting-archive. The contents is the same. Please respect all licenses of the included components. WinARM itself has no additional license.


  • Download the same version but packed with a different packer (7zip) and available as self-extracting-archive here (just ca. 44 Megabytes).

Mirror sites:

  • Alex Gibson kindly provides a mirror-site (
  • Oleg Seiljus from xVerve provides a WinARM-package with an installer and additional drivers for the Signalyzer tool (in the Support/Download-section of the xVerve Web-site).

Updates and Add-Ons:

  • Gérald/dupon jean has sent a ARM makefile-generator similar to Jörg Wunsch's mfile (for AVR). It can be downloaded here.
  • Michael Fischer modified gdb to improve compatibilty with Eclipse. His gdb-Version is available here.
  • A zip-Archive with Dominic Rath's OpenOCD (including some drivers and information) built for Win32 (using MinGW/msys) is available here (ARM7/ARM9/Cortex-M3/XScale for ParPort and FTDI FT2232 interfaces, Mainline/Trunk SVN994). Some packages of older versions can be found here
  • lpc2129_adc_stdio example-update
  • Updated AT91SAM7s-examples
  • MS Windows-binary of lpc21isb V1.43 (beta).
  • Test-release WinARM 20070505: release-notes, Download (self-extracting archive created with 7-zip, 118MB(!)), Download (zip-Archive, 180MB(!))
  • Another test-release: WinARM 20080331. Based on GNU Binutils 2.18.5, GNU gcc 4.3.0 (C/C++), newlib 1.16, GNU gdb 6.8 (with XML and TUI support), OpenOCD SVN527. The precompiled toolchain offers thumb2 support (i.e. for Cortex-M3 like LuminaryMicro LM3S and STMicro STM32.) Again: just a test-release, preliminary tests with examples for LM3S811 and STM32F103 worked as expected. Download the 20080331 test-release [here] (ca. 37MB, no examples included)

WinARM and Keil/ARM uVision

Jaroslav Ban from the Technical University Kosice kindly contributed some files which help to integrate the GNU-Tools from WinARM (arm-elf-gcc/arm-elf-as) into the Keil/ARM uVision IDE. There is a readme-file in the archive with installation- and usage-instructions. (Update mthomas 20070913: objcopy-"glue" for "create hex-file"). [Download] (glue-package version 20070913).

WinARM and Microsoft Vista

Adriaan Beluga has sent the following e-mail: Thanks for your suggestions. With them I managed to get everything to work again under Vista ! ;-) In the end I only needed to modify the path in my batch file which starts "pn.exe". Here is what it looks like now:

@echo off set ARM=c:\WinARM set PATH=%ARM%\libexec\gcc\arm-elf\4.1.1;%ARM%\bin;%ARM%\arm-elf\bin;%ARM%\utils\bin; start /b pn 

Thanks to Adriaan for testing WinARM with Vista (I currently do not have access to a PC running Vista). Users who do not use a batch-file to start Programmers-Notepad or another editor may add the entries to the system search-path from the Workplace properties. So where Windows NT/2K/XP users just added C:\WinARM\bin;C:\WinARM\utils\bin Vista users add C:\WinARM\libexec\gcc\arm-elf\4.1.1;C:\WinARM\bin;C:\WinARM\arm-elf\bin;C:\WinARM\utils\bin .

Information from Michael Langfort: I’m using the 20060606 version of WinARM on Vista Home Premium. When I tried to build a WinARM-based project (that builds fine on WinXp), I got an error:

1>arm-elf-objdump -h -S -C app.elf > app.lss 1>/usr/bin/sh: /c/winarm/bin/arm-elf-objdump: Invalid argument 

This is related to the invalid parameter being passed to a windows api. Aaron Giles page talks about this in relation to MinGW. I went ahead and did his fix, and downloaded MinGW 5.1.3. I deleted the WinARM make and replaced it with the MinGW 5.1.3 make (Its called MinGW-make) and added all the paths spoken about on his page, and now WinARM works. Please think about changing the WinARM Make to match that version. --Michael (mthomas: I will include the mentioned version in to the next WinARM-relase.)
