Re: [Ltib] imx53 QSB on Ubuntu 12.04

[Bair, Richard]

1) Thanks for the input.  Right now I'm merely in learning mode but understand 
your inputs regarding engaging freescale.  

2) I'm close using this recipe but not quite there yet.  From your steps:
a) Complete
b) I haven't seen an error regarding spec files so no action (yet)
c) Complete...I copied all pkgs from BSP into /opt/tlib/pkgs

After performing these steps, I've been trying to use:  Platform="Frescale iMX 
Reference Boards", Development="imx5x", Package Profile="preconfig (Min 
profile)", Board="mx53_loco" and kernel="2.6.35_imx" for a build and u-boot 
builds but the kernel build stops with the text below.  I'm researching the 
error message presently but no path forward just yet.

=================
Hi Richard,

Referring to this and your earlier question.  Here's some advice.

Before you start any of this you have to figure out whether or not anything you 
want to use is legally restricted by Freescale.  I assume you have  copy of 
their BSP.  If so then you have all the parts you need to achieve this in your 
local environment.  If you wanted to get this into the public CVS, you'd have 
to check with Freescale.  Ideally you'd get them to push the platform out (at 
least the GPP content).  Alternatively if someone authoritative there says it's 
okay to publicly distribute all components of that BSP, and you can get that 
CC'd to the list, then it would be possible to include this on the public 
project (not withstanding time available to do it).

Note: they can't place restrictions on any GPL (etc) code they have released to 
you in the ISO image (for example u-boot/kernel patches).  What they can 
restrict though is any of their original content that is not covered by a 
license that allows you free public re-distribution.  Sorry I can't be more 
definitive, but I'm not a lawyer and it really does depend what's in there (I 
don't know).  Aside from the legal side of it, out of courtesy it's best to 
email them and try to get them to help you.  I doubt they're really trying to 
restrict things, I suspect it's more a question of it not being on their radar 
to get stuff pushed out.

To integrate the new platform you need to:

 *   Add the config/platform/_imx53_ platform to a current CVS copy of the LTIB 
sources

 *   Add any new global spec files into the appropriate dist/lfs-5.1/xxx/ area. 
 You can tell which ones may be missing when you try to build the BSP, it will 
complain that it can't find the spec file if it's missing

 *   Add any missing BSP content to /opt/freescale/pkgs.  To figure out what 
GPP/PPP content you're missing run the command: ./ltib --dltest  it will tell 
you what is not on the GPP.  You can then copy the missing files from your BSP 
ISO image (pkgs directory) to /opt/freescale/pkgs (or /opt/ltib/pkgs, they're 
both in the search path).
