The Vivado project can be downloaded from this [https://www.dave.eu/system/files/area-riservata/AN-BELK-004-Interfacing-to-LCD-display_0.zip link] '''<b>TODO''': update link</b>
(*) This signal is used to control backlight. It is usually driven by a PWM signal whose duty cycle is proportional to backlight intensity. For the sake of simplicity, in this project this signal is driven by a GPIO, thus only two intensity levels are supported (0% and 100%). This is a CMOS 2.5V level signal. Make sure that voltage levels of this signal are compatible with LCD backlight input.<br>
Kernel and device tree can also be built with the following procedure:
* update Bora kernel repository (as described [[Bora_Embedded_Linux_Kit_(BELK)/BXELK_software_components#Updating_the_repositories_from_BELK_2.1.0_to_BELK_2.2.0Updating_git_repositories|here]]) '''TODO''': update repo???
* the default KIT binary files of kernel (uImage) can be used.
* build the <code>bora-an004.dtb</code> devicetree
Install root file system on second (ext4) partition of your BELK SD card (firstly deleting all previous rfs files):
* get rfs image [httpshttp://mirror.dave.eu/bora/belk-34.1.0.1/belk-34.01.1_bora0_dave-image-devel-bora.tar.gz bz2 here]
Insert the SD card into Bora/BoraX EVB and turn on the board.
root@bora:~# smart update
* install Qt the <code>tslib</code> required packages using <code>smart</code>
root@bora:~# smart install tslib-calibrate-1.1-r0
