So… I recently installed IDE 1.6.6 on my Windows 8.1 64 bit machine. Everything was fine until I upgraded the SAM and SAMD cores to the latest versions. After doing this, the IDE has not populated the runtime.tools.arm-none-eabi-gcc.path variable, which prevents it from compiling any SAM or SAMD based boards. The resulting error message looks like so:
exec: “/bin/arm-none-eabi-g++”: file does not exist
Downgrading the installed cores does not fix the problem, nor does removing and reinstalling IDE 1.6.6. WTF? Has anyone else encountered this problem?
