In order to repeat the approach illustrated in the TRD, I prepared a brand new PetaLinux project targeting the ZedBoard. Then, since UG1221 gives plenty of details about the Reference Design but doesn’t contain any information about how to build the underlying PetaLinux system, I began to look into the 3 TRD folders downloaded from the Xilinx site and I found 2 files strictly related to the building of the PetaLinux system employed throughout the TRD
- rootfs_config
- packagegroup-trd.bb
The first file is the same as the one I have before making any change to the default configuration, plus the following two lines
CONFIG_packagegroup-trd=y
CONFIG_packagegroup-trd-dev=y
These cause all the packages mentioned in the packagegroup-trd.bb file to be added to the basic PetaLinux system. In particular, the packagegroup-trd.bb file contains the lines shown below
X11_PACKAGES = " \
packagegroup-core-x11-xserver \
packagegroup-core-x11-utils \
dbus \
mini-x-session \
liberation-fonts \
xauth \
xhost \
xset \
xtscal \
xcursor-transparent-theme \
xinit \
xinput \
xinput-calibrator \
xkbcomp \
xkeyboard-config \
xkeyboard-config-locale-en-gb \
xmodmap \
xrandr \
"
QT_PACKAGES = " \
qtbase-dev \
qtbase-plugins \
qtsystems-dev \
qtconnectivity-dev \
qtdeclarative-dev \
qtdeclarative-plugins \
qtimageformats-dev \
qtimageformats-plugins \
qtscript-dev \
qtsensors-dev \
qtsensors-plugins \
qtsvg-dev \

qttools-dev \
qttools-tools \
qtxmlpatterns-dev \
qtbase-examples \
qtquick1-dev \
qtquick1-plugins \
qtquickcontrols-qmlplugins \
qttools-plugins \

"
As it turns out, these are not the packages referenced in the wiki page
http://www.wiki.xilinx.com/Install+and+run+applications+through+Smart+on+target
and in the post
https://forums.xilinx.com/t5/Embedded-Linux/ZynqMP-QT-Setup-PetaLinux-v2017-1/td-p/771854,
Anyhow, I decided to give it a try. So, starting from the basic system coming from the ZedBoard BSP reference design, I first selected all the packages listed under the X11_PACKAGES heading – apart from the xkeyboard-config-locale-en-gb package which I couldn't find. The system was built successfully and I could boot it. Then I made a second rootfs configuration step adding the packages listed under the QT_PACKAGES heading. This time the system was built successfully but it failed to boot with the message
Error: unrecognized/unsupported machine ID (r1 = 0x00000d32).
Of course I didn’t change anything apart adding the QT_PACKAGES to the system; in particular, I didn’t change anything related to the ‘machine ID’.
Given the above results, I made 2 more tests
- ZedBoard BSP reference design + X11_PACKAGES + qtbase
- ZedBoard BSP reference design + X11_PACKAGES + qtbase-dev
In the former case everything went fine while in the latter the PetaLinux was built successfully but failed to boot with the same message as above
Error: unrecognized/unsupported machine ID (r1 = 0x00000d32).
Any help, suggestion or piece of information on the above issues?
