Getting a project for Silicon labs EFM32GG11B420F2048GL120

Hi, I am trying to create an mbed OS project with the chip i mentioned in the title (EFM32GG11B420F2048GL120). I am not being able to compile the project with the EFM32GG_STK3700 target. I have the latest version of GNU ARM and mbed-cli of version 1.7.5. I have set the path for the GCC_ARM_PATH and tool chain to GCC_ARM. I still can't compile the blinky example. mbed compile gives me the following error message:

WARNING: MBED_ARM_PATH set as environment variable but doesn't exist

       Tip: You could retry the last command with "-v" flag for verbose output

Could anyone please help how can i create a project for this chip? Has anyone tried with it? I appreciate your help.

Hi Suman,

It looks like you have not set your GCC_ARM path correctly. On my Windows 10 computer I use the following command to set my GCC_ARM path with Mbed CLI: mbed config -G GCC_ARM_PATH "C:\Program Files (x86)\GNU Tools ARM Embedded\6 2017-q2-update\bin"

Please make sure you are using the path to the root "bin" folder within your GCC_ARM installation directory for your GCC_ARM_PATH. More information about setting your toolchain directories can be viewed here: https://github.com/armmbed/mbed-cli#through-mbed-cli-configuration

Please let me know if you have any questions!
