Management of prebuilt packages[edit | edit source]
During the development of custom applications, developers generally realize that they need to add libraries and other software packages to the root file systems to make their code run properly. If these packages are prebuilt, developers can install them onto the root file system very easily. By configuring the target as described in this document, they achieve a user experience similar to the one you have with a desktop Linux distro such as Ubuntu. DESK-MP1-L uses by default the deb package format. As such, apt commands can be used for package management. Prebuilt packages are provided by this repository that DAVE Embedded Systems makes available for its customers.
apt-get[edit | edit source]
The following instructions detail how to use apt-get for installing packages with Yocto repositories created by DAVE's build system for DESK-MP1-L.
Configuring apt[edit | edit source]
Edit the file /etc/apt/apt.conf like this:
root@desk-mp1:~# cat /etc/apt/apt.conf APT::Architecture "armhf"; APT::Get::AllowUnauthenticated "true"; Acquire::Languages "none";
Edit the file /etc/apt/sources.list.d/debian-10.list like this:
root@desk-mp1:~# cat /etc/apt/sources.list.d/debian-10.list deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ all/ deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ cortexa7t2hf-neon-vfpv4/ deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ desk_mp1/
Execute the following commands in order to re-create the apt cache based on the new server's list:
rm -rf /var/lib/apt/lists/* apt-get clean apt-get update
root@desk-mp1:~# rm -rf /var/lib/apt/lists/* root@desk-mp1:~# apt-get clean root@desk-mp1:~# apt-get update The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA).

Then, modify the cached package list due to the proper DAVE's server configuration:
sed -i 's/\.\//cortexa7t2hf-neon-vfpv4\//g' /var/lib/apt/lists/yocto.dave.eu_desk-mp1-l-1.0.1_cortexa7t2hf-neon-vfpv4_Packages sed -i 's/\.\//all\//g' /var/lib/apt/lists/yocto.dave.eu_desk-mp1-l-1.0.1_all_Packages sed -i 's/\.\//desk%5fmp1\//g' /var/lib/apt/lists/yocto.dave.eu_desk-mp1-l-1.0.1_desk%5fmp1_Packages
Installing packages on target[edit | edit source]
We assume that network interface has been already configured for Internet access. In any case, a simple network configuration can be done according to the How to configure the network interfaces wiki page.
The target is finally ready to install new packages. The following example shows for instance the installation of graphviz:
root@desk-mp1:~# apt-get install graphviz Reading package lists... Done Building dependency tree... Done Reading state information... Done The following NEW packages will be installed: graphviz 0 upgraded, 1 newly installed, 0 to remove and 10 not upgraded. Need to get 2007 kB of archives. After this operation, 0 B of additional disk space will be used. Get:1 http://yocto.dave.eu/desk-mp1-l-1.0.1 cortexa7t2hf-neon-vfpv4/ graphviz 2.50.0-r0.0 [2007 kB] Fetched 2007 kB in 1s (2522 kB/s) The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA).

Other useful apt commands[edit | edit source]
List of configured software repositories[edit | edit source]
As shown before, the target is configured for accessing the Yocto repositories as listed in the /etc/apt/sources.list.d apt configuration directory:
root@desk-mp1:~# cat /etc/apt/sources.list.d/debian-10.list deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ all/ deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ cortexa7t2hf-neon-vfpv4/ deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ desk_mp1/
Search for packages[edit | edit source]
To search for an available package into the current configured channels use apt-cache search
Please note that this will show all packages, it's usually more useful to grep for a pattern, e.g.:
root@desk-mp1:~# apt-cache search vim u-boot-tools-mkenvimage - U-Boot bootloader tools vim-common - Vi IMproved - enhanced vi editor vim-dev - Vi IMproved - enhanced vi editor - Development files vim-doc - Vi IMproved - enhanced vi editor - Documentation files vim-help - Vi IMproved - enhanced vi editor vim-src - Vi IMproved - enhanced vi editor - Source files vim-syntax - Vi IMproved - enhanced vi editor vim-tiny-dev - Vi IMproved - enhanced vi editor (with tiny features) - Development files vim-tiny-src - Vi IMproved - enhanced vi editor (with tiny features) - Source files vim-tiny - Vi IMproved - enhanced vi editor (with tiny features) vim-tools - Vi IMproved - enhanced vi editor vim-tutor - Vi IMproved - enhanced vi editor vim-vimrc - Vi IMproved - enhanced vi editor vim - Vi IMproved - enhanced vi editor
List of installed packages[edit | edit source]
User can see the list of installed packages with dpkg --get-selections | sed 's:install$::' (sed removes the install string from the output list)
acl adwaita-icon-theme-symbolic alsa-conf alsa-plugins alsa-plugins-pulseaudio-conf alsa-state alsa-state-stm32mp1 alsa-states alsa-topology-conf alsa-ucm-conf ...
