µOS++ v6.3.14 released
Posted on July 4, 2018 by Liviu Ionescu.
Version v6.3.14 is a µOS++ maintenance release. The main addition
is the functional POSIX I/O subsystem, which supports character devices,
block devices and file systems.
Affected packages
Download or update
As of now, the µOS++ code is split between several GitHub projects
and needs to be brought together to compose a project.
To automate this process, some scripts are available from a
separate project.
To update the local copy of the xPacks, use the
scripts.git/xpacks-update-repo.sh script.
To experiment with µOS++, please check the demo projects, available from
GitHub,
and use a similar structure for your projects.
