Hello, I am trying to get GNUARM4 working with uVision3 but with little success. I have followed the instructions here: http://www.keil.com/support/docs/3127.htm which direct me to set the following values: GNU-Tool-Prefix: arm-elf- Cygnus Folder: C:\Program Files\GNUARM\ However, I still get the error message: --- Error: can't execute 'arm-elf-gcc' GNUARM was downloaded from this website: http://gnuarm.com/ The two versions I have tried are: bu-2.16.1_gcc-4.0.1-c-c++_nl-1.13.0_gi-6.1.exe and bu-2.15_gcc-3.4.3-c-c++-java_nl-1.12.0_gi-6.1.exe Any help would be greatly appreciated.

You should move your GCC to a folder without spaces.
