two layers: hardware and distro.

two layers: hardware and distro.

[João Henrique Freitas]

Hi,

I am novice yocto user.

My target is create a BSP to my hardware+application. Is Yocto a
suitable project to do it?

I want to create two layers:

bsp-myhardware: linux kernel, firmware, specific hardware configuration
bsp-myapplication: linux distro with all software need. Ex: net-snmp,
lksctp (the target is telecom applications)

Currently yocto does not have many recipes that I need. No problem, I
can get from OE. We use kernel 2.6.22 and I presume that I need a
recipe to it and put inside bsp-myhardware, right?


Thanks.

Yes, this sounds like a very reasonable approach.

In general (this applies to anyone out there), we're interested to know
what kinds of software people use so please let us know what you're
putting into application layers anyone creates like this. Our focus is
currently on making sure there is a rock solid core for people to build
from but if there are core applications missing we'd like to know about
it.

Also, if anyone establishes a layer with a specific focus, we're happy
to provide a git repository for it on git.yoctoproject.org where you
could maintain and share this code with other people with a similar
goal.

Cheers,

Richard

Hi,

I can tell about what applications we will use and contribute with
some questions.

We are focus on Telecom applications and I am setting a BSP to a Media
Gateway and Sigtran Gateway.

Thanks.

Any interest in moving to a newer/different kernel ? The
supported kernel for yocto is at 2.6.34 and I'll have a
-dev tree tracking 2.6.37 shortly.

My interest is getting more BSPs using the same kernel
version so we can leverage the common set of issues,
bug fixes, CVEs, etc. It also helps me streamline the
BSP bootstrapping process, which is a primary focus of
mine at the moment.
