[U-Boot] Coldfire Architecture and SELF

[SANCHEZ]

Hi all, 

 

I wanted to develop a personalized U-Boot to my MCF54455 Coldfire V4 microcontroller. 

 

I got the sources from DENX FTP server and now I wanted to get the SELF but I don't really know wich one should I download. Maybe someone could push me in the right direction?. Thanks.

 

Cheers:

I am not sure what you want to do. Use U-Boot from the git repository,
this should be up to date for MCF5445x. Use a decent toolchain - for
U-Boot, I always had good results with the pre-compiled versions from
CodeSourcery. Then you should be set to compile your own U-Boot with
minimal effort.

Coming to Linux (which you seem to target with SELF?), my experience is
you have to use the horribly outdated LTIB package provided by Freescale
because they did not push any of their changes back to mainline.
I would be happy if anybody could prove me wrong in this regard, but this
is my experience from almost 1 year ago until May 2010.

Wolfgang

You are welcome.

What exactly do you mean by "SELF" in this context?

To me, "SELF" means "Simple Embedded Linux Framwork", which is the
name for a small root file system for embedded Linux targets; as such,
it is completely unrelated to U-Boot, so I fail to understand what you
might be looking for.

Just to remove any ambiguity here: This refers to Coldfire, it seems
to be completely different for the other architectures.

Hi again,

Thank you for your fast answers. 

Sorry. I was reading the manual in the U-Boot webpage and miss understood some of the topics. I just wanted to get the develop tools in order to compile and develop the U-Boot for the MCF54455. The manual points something (toolchain?) called ELDK that runs under Linux, but currently I'm tied to Windows as host. I don't know the version to install either since I can't find the Coldfire v4 architecture file in the FTP server.

Any development platform or tip will be welcomed. By the way, right now I only have intalled CodeWarrior for Coldfire v7.2 and Code Composer Studio 3.3.1. Should I try with Codesourcery?

Cheers,
 
Guillermo Sanchez Vitorica

of course, the best solution is to switch to Linux as a development
host. ;-)
There are many possibilities, but I think the second best possibility
is using coLinux to set up a "virtual" Linux on top of your Windows box. *)
In this virtual Linux, you can do anything you would do in a native
Linux box, including using LTIB and ELDK (is there a version of the
latter for coldfire meanwhile?!).

Setting up coLinux on your own can be a bit tricky. Maybe somebody can
recommend a pre-built image for it that does not have some strange
non-standard default settings?

Regards,
Wolfgang

*) While coLinux is really fast for most applications, it has some
performance issues when using graphical tools because (to my knowledge)
there is no fast and free X-Server for Windows. However, in my experience
this is no real problem because the applications I used (editor, debugger)
were not so demanding in this respect. Using such a bloated thing like
eclipse is definitely not something you want to do with this combination,
but IMHO this is more a conceptual problem of Eclipse (or Java?) than
coLinux...

Hi again,

 

So, if I have got it straight, with VirtualBox + Ubuntu + ELDK + U-BOOT sources I can start developing U-BOOT for the MCF5445EVB?

Hello,

One last thing on this topic. Could I use also CoudeSourcery Lite +
Coldfire toolchain ? 

Kind regards,

Guillermo

for U-Boot: yes
For Linux (ELDK/LTIB), it is IMHO better to rely on the toolchain
provided with the ELDK/LTIB package you use.

Hello all,

I feel a little bit silly for asking this but, is the Coldfire
Architecture supported by ELDK?
