Freescale U-Boot User's Guide

Freescale U-Boot User's Guide

[tom campbell]

I'm upgrading from Freescale's Yocto Beta release to Freescale's GA release.

In the "Freescale Yocto Project User's Guide" Doc# IMXLXYOCTOUG, Rev 
L3.10.17_1.0.0ga, 05/2014
In section 5.4 U-Boot Configuration, page 7 it refers to:

     Freescale U-Boot User's Guide

I can't seem to find that document.  Can anyone point me to it?

thx

Hi Tom,

Where are these docs you are referring to?  Are they on the Freescale 
Community site?

It's not clear to me whether you are an i.MX/ARM developer or QorIQ (ARM 
or powerpc)

For me, I can find Freescale u-boot documentation in my "Freescale Linux 
SDK for QorIQ Processors" documentation folder.  This is part of the SDK 
tar ball.  I think this same information is available on freescale.com 
at their infocenter, but it seems to be down at the moment (at least for 
me).

It's never been clear to me where developers using Freescale devices are 
supposed to look for the latest stable yocto/linux documentation & 
patches: SDK, Yoctoproject.org, freescale.com, git.freescale.com or 
community.freescale.com.

I would appreciate someone letting me know if this has been clarified 
recently.

Thanks,

Bob

Hi Bob, 

For QorIQ PPC SDK, following is the mirror info. 
SDK ISOs: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=SDKLINUX
SDK public source/patch: http://git.freescale.com/git/cgit.cgi/ppc/sdk/
Yocto: http://git.freescale.com/git/cgit.cgi/ppc/sdk/ or http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-ppc/
SDK documentations: http://www.freescale.com/infocenter -> Software and Tools Information Center -> QorIQ SDK Documentation
			or source ISO

We are working on the integration of meta-fsl-ppc layer into FSL Yocto community BSP(http://freescale.github.io/), hopefully it can be done in 1.7 release. 


Best Regards,

Zhenhua

Thank you for the reply Zhenhua.

Here's my fundamental problem (as I see it):

Let's say we're getting ready to release a product using the FSL SDK 1.5 
for QorIQ.  I assume there are many customers to the 1.5 SDK and bugs 
are being found & reported on a regular basis.  Some of these bugs will 
not be seen here during development but eventually impact our product in 
the field.

Freescale has a private service request (SR) system for supporting SDK 
bug requests and also offers paid premium SDK support.


How can I use the systems in place (e.g., FSL public git and 
Yoctoproject.org) to learn which SDK bugs have been reported and patched 
and then grab the appropriate patches to create an incremental build? 
It's not sufficient to only have a system in place to help resolve the 
bugs we find ourselves.

As far as I know, the yocto repos never contain enough data to build the 
FSL SDK (some of the data on the SDK is kept private), and the FSL 
public git seems to be significantly behind (at least meta-fsl-ppc).

It seems to me that Freescale should have a customer visible bug 
reporting system in place for their SDK and maintain a complete, 
up-to-date SDK branch with patches in response to the bugs reported & 
closed out.

If IP protection is the reason to not do it, then deploy it on an 
extranet that is password protected.

Lastly, is there a mail list for the FSL public git?

Thank you,

Bob

[Luo Zhenhua-B19537] To support above requirement, the bug related info needs to be included in the commit message for better patch finding, we will consider the enhancement in future. In current SDK. The resolved critical bugs can be got from SDK documentation(SDK Overview -> Known Issues).

[Luo Zhenhua-B19537] Currently the recipes update for meta-fsl-ppc in public git(git.freescale.com and git.yoctoproject.org) are done when the QorIQ SDK is formally released(two major releases per year). We are working on the process of more frequent release for QorIQ SDK, and more and more packages will be published in public git.

[Luo Zhenhua-B19537] There is no dedicated mail list for FSL public git. Currently meta-freescale@yoctoproject.org is used by community for discussion of FSL SDK. FSL community website(https://community.freescale.com/) can also be leveraged to raise issue and question.

Bob/List/Lauren:

I'm an i.MX/ARM developer.

Thank all for response.

I would echo Bob's sentiments that the Freescale QA release badly needs 
a "home landing page" with links to follow for documentation and the 
like.  The Freescale documentation is IMHO quite good (thank you).  
Finding it is a another matter.  I'm new to Yocto (which I like), but 
the layered architecture makes finding who is responsible for what and 
locating the appropriate documentation more than daunting to a newbie 
Yocto user..... and this is coming from a grizzled embedded linux 
veteran on his Nth build system.  I can only image the glazed eyes of a 
rookie C programmer coming from a single proprietary os.

The closest thing I found to a "home page" is 
http://freescale.github.io/#header-section whose documentation link goes 
to http://freescale.github.io/doc/release-notes/1.6/.  I downloaded the 
tarball of fsl-yocto-3.10.17_1.0.0.tar.gz from somewhere from 
Freescale.com (I think).  I would think it ought to be pointed to from 
the "home page" somehow.  Maybe it is, and I can't find it.

I understand that there are plethora of Freescale products and I only 
care about one, but I suspect other product lines suffer from the same 
issues.  To be fair, I haven't looked into the build directories created 
by yocto/bitbake.  It may be that some of this documentation is there. 
(I'm focusing on getting the GA release to run on a custom board at the 
moment).

Next on my list is to build the toolkit for u-boot development outside 
of yocto and the sdk for eclipse development.  General question.  If I 
understand the process, building the toolkit (sorry I forget the exact 
target name) installs all the appropriate cross-compilers/linkers needed 
for the i.Mx.  Normally a clean yocto build via bitbake also completely 
builds the cross-chain compilers/linkers.  Are the yocto recipes smart 
enough to use any existing cross compliers?  Do I have to edit a recipe 
file?  Is it a bad idea?  Basically looking to reduce the build time.

 From memory, the github.io points you to installing sphinx and 
self-generate documentation locally from git:github.io.  Is it's content 
currently available on the web?

I would also echo Bob's request for a freescale bugzilla or equivalent.

there are 2 yocto freescale releases. two.

1) FSL Community BSP is what you find when you talk about githubio
2) meta-fsl-bsp-release is what you find when you talk about "Official
Freescale GA Release"

for the "Official Freescale GA Release" you go to
www.freescale.com/imx and search for the Doc bundle, just the same way
you did for other LTIB releases.

in case you´re new to i.mx family (sorry, i did not underdand if you
are or not) this is the URL to the place where you find the bundle:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=RDIMX6SABREBRD&fpsp=1&tab=Documentation_Tab

look for: L3.10.17_1.0.0_LINUX_DOCS  Linux 3.10.17 BSP & MM Bundle


So, what we have here is "almost" the classic upstream scenario. The
company works internally only and after "the release" it is published
and the community can take it. Next release the company creates, it
includes any the improvements/bugfixes/feedbacks from community.

Let me know what you think and your next question
(and please, I ignored all other questions but I would like to have
them in a separated thread, if you don´t mind)

Thank you Tom. From my perspective, there are two different release 
models for Freescale: iMX and QorIQ.  I'm more interested in the latter, 
but I try to stay current with the ARM builds for our SABRE board.

I have been trying to figure out if & when the release models will merge.

It appears that iMX has a great community structure built around it.
