Hi,
If you try to compile the sample project within S32K14X_MCAL4_2_RTM_1_0_0, you should take care of the command if you use Linaro.
After you set the environment of compiling and run the command under command window, you should enter
"launch.bat MODE=USER TOOLCHAIN=linaro"
NOT
"launch.bat MODE=USER TOOLCHAIN=LINARO"
The command is case sensitivity.
Hope you can compile the project successfully.
Cheers!
Oliver
