IMX6 Nitrogen6x with Linaro hardware floating point toolchain
This page shows the advances to integrate Linaro hardware floating point with the iMX6 Nitrogen6x, specially with the gstreamer freescale plugins. For this integration, we are using the boundary-imx_3.0.35_4.0.0 kernel version and gcc-linaro-arm-unknown-linux-gnueabihf-4.8.2-2013.07 Linaro toolchain version.
We are using the following freescale plugins:
- firmware-imx-3.0.35-4.0.0
- imx-lib-3.0.35-4.0.0
- libfslcodec-3.0.8
- libfslparser-3.0.8
- libvpuwrap-3.0.35
- gst-fsl-plugin-3.0.7
Advances
- We are able to compile all the sdk without errors.
- Bootloader and kernel boot perfectly.
- All the gst-fsl-plugins are working:

- We are able to see a camera video loopback.
- Video and audio are working correctly.

Software Floating Point
The iMX6 Nitrogen6x SDK is also working completely with the Linaro software floating point, all the gst-fsl-plugins are loading without errors. The Linaro toolchain version used for software floating point is:
gcc-linaro-arm-linux-gnueabi-2012.03-20120326_linux
