Jump to: navigation, search

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


  1. We are able to compile all the sdk without errors.
  2. Bootloader and kernel boot perfectly.
  3. All the gst-fsl-plugins are working:
/ # gst-inspect | grep imx
mp3enc.imx:  mfw_mp3encoder: mp3 audio encoder
mp3dec.imx:  mfw_mp3decoder: mp3 audio decoder
beep.imx: ac3: ac3
beep.imx: 3ca: ac3
beep.imx:  beepdec: beep audio decoder
beep.imx:  beepdec.vorbis: Vorbis decoder
beep.imx:  beepdec.ac3: AC3 decoder
beep.imx:  beepdec.wma: WMA decoder
beep.imx:  beepdec.mp3: MP3 decoder
beep.imx:  beepdec.aac: AAC LC decoder
aacdec.imx:  mfw_aacdecoder: aac audio decoder
amrdec.imx:  mfw_amrdecoder: amr audio decoder
mpeg2dec.imx:  mfw_mpeg2decoder: mpeg2 video decoder
mpeg4dec.imx:  mfw_mpeg4aspdecoder: mpeg4 video decoder
ipucsc.imx:  mfw_ipucsc: IPU-based video converter
vorbisdec.imx:  mfw_vorbisdecoder: vorbis audio decoder

isink.imx:  mfw_isink: IPU-based video sink
aiur.imx: webm: webm
aiur.imx:  aiurdemux: aiur universal demuxer
audiopeq.imx:  mfw_audio_pp: audio post equalizer
vpu.imx:  vpudec: VPU-based video decoder
vpu.imx:  vpuenc: VPU-based video encoder
v4lsrc.imx:  mfw_v4lsrc: v4l2 based camera src
aacpdec.imx:  mfw_aacplusdecoder: aac plus audio decoder
v4lsink.imx:  mfw_v4lsink: v4l2 video sink
  1. We are able to see a camera video loopback.
  2. 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:
