[meta-freescale] building embest marsboard with the latest yocto project

Wed Jul 1 02:59:40 PDT 2015

Thanks Ms Daiane Angolini,

I am intended to use embest marsboard for electric vehicle controller 
purpose:

  * CAN for communicating with electric motor controller and battery
    management system.
  * LVDS for communicating with touchscreen and HDMI for communicating
    with passenger LED TV
  * GPIO for all controlled devices such air conditioning and power steering
  * 3G capable to send real time electric motor and battery data
    performance.
  * GPS capable to discover location and mapping nearest charging station.
  * Wireless Camera for driver sleepy detector

I am intended to purchase your book Embedded Linux Development with 
Yocto Project with mr Otavio Salvador. Hopefully there's a clear 
information how to use HOB with I expect to be easier.

The issue raised as following:

 1. The current kernel is using 3.04. I have downloaded poky fido 1.8
    hopefully may utilize all gpio including lvds touchscreen.
 2. Just in case I have successfully build my image then how to install
    it into e-MMc. Do I have to use manufacturing tools from freescale
    or yocto has tools to do that?
 3. I need to use opencv for driver sleepy detector. I need to know how
    to put openCV models into yocto recipe?

Please advise,

Riza
