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 Toradex, December 3, 2014
