Embedded Linux Platform Specifications
Hello fellow Debian Developers,
I am currently participating in the standard specification
process of Linux embedded core platforms, as an individual
developer. The effort is driven by the "vendor-neutral"
trade association, Embedded Linux Consortium. See the
Hopefully, we will produce specifications for several
platforms, to accommodate from the lowly non-MMU uClinux to
full-functionality headless Linux servers by the end of
I am planning to submit a proposal for adding functionality
dynamically (including API for changing/querying the
capabilities) on top of the base profiles. I am aware of
a couple of proprietary ways of doing it. But, I will need
your advice on current "open" practices.
In my work with embedded Linux, I have encountered several
situations where I have just enough flash for a minimal
functionality, but there is enough RAM to extend capabilities.
For examples, we have a device that has only 16 meg flash but
64 meg RAM. The base configuration is adequate for some
C-language binding applications. However, certain applications
like speech processing and voice recognition will need to be
downloaded and run primarily on RAM. Another example would be
Java-based OSGI bundles.
There are a couple of ways to extend the capabilities.
(1) XML-based messages have been used to query, to download and
to install additional packages onto the RAM-based filesystem.
(2) I have also used a proprietary C-based to query and to
I think there are probably also something similar to DOCSIS's
snmp-based firmware/software upgrades: RFC2669.
For the standard specification, I am looking for an API or
current practices that are within the Debian Open-Source
Specifications. I think the benefits of an "open" API will be
tremendous in uniting the embedded Linux market.
Appreciate any assistances and comments.
