●
u-boot-am33x
: the U-Boot source tree
●
yocto
: the Yocto SDK installation directory
●
qtcreator-x.y.z
: pre-installed and pre-configured QtCreator IDE for
Qt application development
●
rfs
: XELK provides three root file systems:
axel-base
: minimal root file system with basic
packages (
/home/dvdk/xelk/rfs/axel-base
)
axel-fsl-image
: full root file system with lots of
packages (including the gui application from NXP /
Freescale) useful during the development phase
(
/home/dvdk/xelk/rfs/axel-fsl-image
)
axel-qt5
: root file system with Qt 5.3.2 libraries and
examples (
/home/dvdk/xelk/rfs/axel-qt5
)
●
env.sh
: a bash script for setting the environment variables, containing the
following lines:
export
PATH=~/xelk/yocto/sdk/axel-qt5/sysroots/x86_64-
pokysdk-linux/usr/bin/arm-poky-linux-gnueabi:
$PATH
export ARCH=arm
export CROSS_COMPILE=arm-poky-linux-gnueabi-

TFTP Server
One of the most useful features of a bootloader during development is
the capability to download the Linux kernel from the network. This saves
a lot of time because developer doesn't have to program the image in
flash every time he/she modifies it. U-Boot implements the TFTP protocol
(see the tftp command), so the host system must be configured to enable
the TFTP service. Installation and configuration of a TFTP server
depends on the host Linux distribution.
The default DVDK tftp installation has
/srv/tftp
as work directory. A
subdirectory dedicated to the image files associated to the XELK
(
/srv/tftp/xelk
) is available, but developers can add their custom
subdirectories when required.
