Re: [Ltib] imx53 QSB on Ubuntu 12.04

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).

Regards, Stuart

Hello and thanks for reading!

I'm new to the imx53 QSB and that processor family in general.  I have two questions/issues:

ITEM 1
======
I've successfully installed the CVS update of LTIB on Ubuntu 12.04 based on support from this list.  I was able to successfully build uboot and a 2.6.22-mx kernel selecting one of the supported platforms (imx31 ads).

The issue I have is that the platform for the imx53 is not available by default in the CVS and that's my current target.  I've been somewhat successful getting the imx53 and im5x "menu items" to appear when I copy from the BSP tree to the CVS tree.  Specifically, I copy:

/home/rich/imx53/L2.6.35_11.09.01_ER/L2.6.35_11.09.01_ER_source/ltib/config/platform/imx

to the CVS build tree.  Again, this allows me to pick "imx Reference Boards" and an "im5x" platform when I run ./ltib.  However, typically uboot will build and the kernel will fail (I'll post the message later today).

a) Is there a process for integrating imx53 BSP support into the main CVS?  How?

The integration may have to come from Freescale due to license
restrictions.  Even if you wanted to integrate it, you may not be
allowed to distribute it [to us].   Now that Freescale requires a
login to get to their bsp's, I would not give out whatever I
downloaded unless I had specific permission to do so (that's just me).
  Stuart may be able to provide some more insight to the process if
one exists.

b) I also request support on the error message (again, will post near-term)

ITEM 2
======
Once I have built /rootfs, is there a script for copying to the uSD card?  So far I've only created the uSD card using the windows application:  MCIMX535-START-R-BSP-11-09_C.exe.

You may have to dig into your bsp package but for my board there were
instructions on how to format and copy files-systems to flash, sd or
hd.   i've use one called /root/diskinit-1.2.sh.  Generally these type
of short scripts either tftp the disk image or mount the host nfs
share and the contents are simply copied.  Nothing special about it.

Any advice you could offer would be appreciated.

Thanks,
Rich
