Installation, patching and building the SDK
The i.MX 6 Series Platform SDK v1.1.0 does not enable neither the MMU nor L1/L2 Caches (depending on the benchmark you are running, enabling these yield much better numbers), so there is a need to patch the code to enable these. Please download the SDK from the Freescale portal and the patch attached on this document, then follow these instructions:
$ tar zxvf imx6_platform_sdk_v1.1.0.tgz
$ cd iMX6_Platform_SDK
$ patch -p1 < 0001-add-L2-cache-enable-to-mx6-SDK-1.1.0.patch
$ export PATH=$PATH:<toolchain_install_path>/bin
For more help, please look at the README.pdf and documents inside the doc folder.
