*****************************************************************************************************************************************************************************************
NAND Boot: Colibri T20 256MB V1.1b (Sample), Colibri T20 512MB V1.1c (Sample), Colibri T20 256MB V1.2a, Colibri T20 512MB V1.2a, Colibri T20 256MB IT V1.2a or Colibri T20 512MB IT V1.2a
*****************************************************************************************************************************************************************************************

Initial Preparation:
- download and extract T20_AndroidImage_Vx.yz.tar.bz2 package

Optional Google Apps Installation:
- download latest gapps-ics-xyz-signed.zip as described on http://wiki.cyanogenmod.org/w/Gapps
- extract contents of system folder from gapps-ics-xyz-signed.zip into previously extracted rootfs folder
- e.g. unzip gapps-ics-xyz-signed.zip; sudo cp -pPR system/* rootfs

Optional TFTLCD Resolution Selection:
- LVDS aka TFTLCD resolution hard-coded in kernel
- following pre-compiled kernels provided
  uImage-3.1.10-colibri_t20-android-4.0.4-720p
  uImage-3.1.10-colibri_t20-android-4.0.4-et070080dh6
  uImage-3.1.10-colibri_t20-android-4.0.4-fusion10
  uImage-3.1.10-colibri_t20-android-4.0.4-vga
- just symlink desired one as follows:
  cd bin; ln -fs uImage-3.1.10-colibri_t20-android-4.0.4-720p uImage; cd ..
- separate kernel replacement can be achieved using -k update.sh script option

Flash NAND:
- EvalBoard V3.1a
  - connect USB B (X29) or USB micro A/B (X30) to development workstation using regular or micro USB cable
  - the jumper JP2 must be open
  - press and hold recovery mode switch (SW9) during power up
- Iris V1.1a
  - connect USB micro A/B (X12) to development workstation using regular micro USB cable
  - short pin 1-2 of JP1 on Iris for RECOVERY
(other carrier boards see http://developer.toradex.com/knowledge-base/txx-recovery-mode)
- make sure that the carrier board supports USB high speed
  - Iris & EvalBoard V3.1a OK, for other carrier boards see http://developer.toradex.com/knowledge-base/usb-2.0-high-speed-%28480mbps%29 )
- apply power or reset
- run update.sh script
- use -r 512 option for 512 MB RAM modules
- use -v V1_1 option for V1.1b or V1.1c modules

Boot from NAND:
- EvalBoard V3.1a
  - do no longer press SW9
- Iris V1.1a
  - do no longer short any pins of JP1
- power cycle
- upon first boot Java classes are preloaded and cached which takes around 2 minutes, please be patient
