Linux Kernel

Fsl-community-bsp supports to sources for Linux Kernel:

  • linux-imx: Linux Kernel supported by Freescale
  • linux-fslc: Linux Kernel mainline with backported fixes (


The following table shows the version of Linux Kernel provided by Freescale for each supported machine.

Board Kernel Verion_FSL BSP
imx28evk 2.6.35_1.1.0
imx51evk 2.6.35_11.09.01
imx53qsb 2.6.35_11.09.01

imx6slevk 3.0.35_12.10.02


linux-fslc provides the Linux Kernel 3.8.8 from mainline ( with some backported fixes.

For the mainline kernel some boards has a very good support, although other ones has only a basic support.

Please, see in the following table which are the main features supported by mainline kernel for each supporte board.

Machine Basic Feature List


Fsl-community-bsp supports to sources for u-boot:

  • u-boot-imx: U-Boot supported by Freescale

Userspace Packages

There is a huge number of userspace packages provided by Yocto. The following table shows some version for few highligthed packages.

gstreamer all 0.10.36
udev all 182
xserver-xorg MX6 1.11.4
xserver-xorg all 1.13

Freescale Userspace Packages

This section shows the version package for each board. Those packages provides hardware acceleration for GPU or VPU, provides hardware optimization or some hardware test tools.

Hardware acceleration is achieved using a different core for processing some specific task. In this case, GPU or VPU.

Hardware optimization is achieved with some changes in source code in order to get a better performance for a specific task in a specific hardware. For example, audio decode made by software, but with optimizations for ARM.

Hardware relate is applicable when the package was designed to be executed in a specific hardware, and it does not make sense in other hardware. For example, imx-test is a test package for imx boards. It can be cross-compiled for any other core, although it will only act as expect if executed on imx boards.
