That part should have worked for you, though it will only have
support for the 10.1" Freescale display.

Why did you do this part? Was it because of this bit in the U-Boot
README?

Otavio, does the "mx6qsabrelite" configuration place U-Boot in
unformatted space?

I'm not seeing that a boot script is created in the machine layer:
	https://github.com/Freescale/meta-fsl-arm-extra/blob/master/conf/machine/imx6qsabrelite.conf

If the image does what I think it does, and has unformatted
space before the first formatted partition, you may be able
to do this by hand like so:

	sudo dd if=u-boot.imx of=/dev/mysdcard bs=512 seek=2

If that's the case, you can use the imx_usb tool described here
to at least load U-Boot over the USB link

There's no NAND on the board. Only SPI-NOR.

Sorry for the confusion here. It seems that some piece of
documentation went missing.

In general, we're recommending the use of the nitrogen6x
machine, even for SABRE Lite as discussed in a separate
thread yesterday.

It does; I am thinking in make it (imx6qsabrelite) an alias to
nitrogen board. This way people don't get confused about  missing
machine but it works as expected.

Do you have a blog post or something explaining how to put the u-boot
in the NOR?

We have lots of those, and that may be a part of the problem,
since we transitioned from the U-Boot 2009.08 to Main-line a
while back.

I'll put together another one that's a bit more definitive since
things are now pretty stable.

Silly me.

I thought this would only take a few minutes, but I did put
together a U-Boot "Getting started" guide:
	http://boundarydevices.com/u-boot-on-i-mx6/

Upgrading U-Boot is normally just a matter of placing the version
of U-Boot (file name u-boot.imx) and the script 6x_upgrade
on an SD card and running the "upgradeu" command as shown here:

	http://boundarydevices.com/u-boot-on-i-mx6/#upgradeu

Thanks Fabio,

BTW, there's a thread on i.MX Community that I think
is misleading:
	https://community.freescale.com/docs/DOC-93844

Daiane, you indicate that the manufacturing tool works
for SABRE Lite, but there's currently no support for
the USB OTG port in main-line U-Boot.

Troy's been trying to get time to remedy this, but
hasn't yet done so.

Does someone know something that I'm missing?

Is anybody else working on this?

This is also the gating item for Android Fastboot
support, and the biggest omission in main-line.

We have a feature matrix available here:
	http://boundarydevices.com/main-line-u-boot-for-i-mx6-sabre-lite-and-nitrogen6x/

Please advise,


Eric

Well, I can only say for myself. And I'm always scared when my board 
does not seems to be alive.

In the past, when I was still working with sabrelite. I used mfgtools to 
copy *any* uboot to nor and then make anything needed afterwards.

The only think I'm sure. We (meta-fsl-arm) have a problem. Sabrelite 
does not work out of box. It must be fixed someway.

I hope we can find a way that keeps imx6sabrelite.conf file. Because 
several people are working this sabrelite.

Because the mfgtools uses the serial download protocol, it's likely
that the first stage will work (the piece that downloads U-Boot
into RAM), but the next stage (programming SPI NOR) can only
occur if the U-Boot version supports USB OTG, and main-line
doesn't yet.

Unfortunately, I don't have ready access to a Windows
machine, and it's a pain to test...

I think Otavio's answer is easiest.

More than several, I'm sure.

I mean, several people have being reporting errors when using 
meta-fsl-arm with sabrelite. I don't have numbers =P


Could you, please, share in imx-community, your doc? ^.^

The blog post is awesome; it just lacks one important information: how
to program Boundary's U-Boot in case the user has did the Linaro's NOR
overwirte? This would allow us to use:

--- imx6qsabrelite.conf
#@TYPE: Machine
#@NAME: Boundary Devices i.MX6Q SABRE Lite
#@SOC: i.MX6Q
#@DESCRIPTION: Machine configuration for Boundary Devices i.MX6Q SABRE
Lite

# WARNING: This board now use the *same* code as Nitrogen6X and it
#          boots from internal SPI NOR memory. If you did change it to
boot
#          from the MMC (SD3 or SD4) please check the Boundary's blog
post
#          at: http://boundarydevices.com/u-boot-on-i-mx6/

include conf/machine/nitrogen6x.conf

Do you agree?
