Toradex cross tool chain

Hard disk space requirements for open embedded gtk eclipse cross tool chain configuration for toradex???
I am amazed to see that 60 GB free space is recommended???

Yes, 60 GB is maybe a little bit excessive however even the official Yocto Project Quick Start guide recommends 50 GB. Alternatively you may use a pre-built cross tool chain or SDK which will only account for a few gigabytes.
