FSL Community Yocto 2.4 Rocko BSP

To get the BSP you need to have repo installed and use it as:

Install the repo utility:

$: mkdir ~/bin
$: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$: chmod a+x ~/bin/repo

Download the BSP source:

$: PATH=${PATH}:~/bin
$: mkdir fsl-community-bsp
$: cd fsl-community-bsp
$: repo init -u https://github.com/TechNexion-customization/fsl-community-bsp-platform.git -b rocko-tn
$: repo sync -j8

Prepare WIFI/BT firmware

Under sources/meta-edm-bsp-release/recipes-bsp, there are two directories: "firmware-legacy" and "firmware-bcmdhd" which contain wifi/BT firmware files.

1. firmware-legacy: This directory contains wifi/BT firmwares for BCM4330, the firmware files are from Linux-Wireless and added by default.

2. firmware-bcmdhd: This directory is supposed to contain the WIFI/BT firmwares of Ampak AP6335(BCM4339) and AP6212(BCM43438). Because of the license restriction, please contact TechNexion FAE or Sales to get licensed firmware files. After getting the firmware binary:

   1. Put all the firmware files into sources/meta-edm-bsp-release/recipes-bsp/firmware-bcmdhd/files.

   2. Activate the deployment of Ampak AP6335(BCM4339) and AP6212(BCM43438) firmware files:

      $: cp sources/meta-edm-bsp-release/recipes-bsp/firmware-bcmdhd/files/firmware-bcmdhd_1.0.1.bak sources/meta-edm-bsp-release/recipes-bsp/firmware-bcmdhd/firmware-bcmdhd_1.0.1.bb

Configurations for setup script

“MACHINE” is the target of build. It usually corresponds to the name of SOM or SBC.

For more information, please check the file under “sources/meta-edm-bsp-release/conf/machine”.

“DISPLAY” is the disply type. This option only works on i.mx6 (i.mx6 Solo/Dual Lite/Dual/Quad) SOMs and doesn’t work for i.mx6ul, i.mx6sx and i.mx7.

“BASEBOARD” is the baseboard type. This option only works on i.mx6 (i.mx6 Solo/Dual Lite/Dual/Quad) SOMs and doesn’t work on i.mx6ul and i.mx6sx.

“-b” specify the build directory.

“-e” sets the graphical back end for frame buffer and direct fb images. X11 is default if no backend is set.
