[meta-fsl-arm-extra][PATCH 0/3] Initial support for Nitrogen6X

[meta-fsl-arm-extra][PATCH 0/3] Initial support for Nitrogen6X

[Otavio Salvador]

This patchset adds support for Nitrogen6X using the deployment used by
Boundary Devices. The generated sdcard should just work in the board.

The patches are untested as I don't own a Nitrogen6X and would be good
if someone could test those before we apply them.

Otavio Salvador (3):
  u-boot-boundary: Add U-Boot recipe for Boundary Devices version
  u-boot-script-boundary: Add recipe to deploy the boot scripts
  nitrogen6x: Add machine definition

[meta-fsl-arm-extra][PATCH 3/3] nitrogen6x: Add machine definition

[Otavio Salvador]

This adds the machine definition to Nitrogen6x from Boundary Devices.
More information at:

http://boundarydevices.com/products/nitrogen6x-board-imx6-arm-cortex-a9-sbc/

In order to take advance of same code used for imx6qsabrelite (on
linux-imx, u-boot, imx-firmaware), we use a MACHINEOVERRIDES trick, so
imx6qsabrelite is taken as a fallback for nitrogen6x machine.

Eric and Troy,

Please give this patchset a try as I don't own the board to try it myself.

Please bear on mind that this patchset depends on the "[PATCH 0/2]
Flexibilize sdcard generation" patchset to proper work.

Will do.

The patches all apply cleanly to meta-fsl-arm and I'm building now.

Understanding will likely take a while ;)

Thanks Otavio,

If so, it will feel like Christmas!

After pulling all kinda N00b stuff, I finally got a build to complete
for 'nitrogen6x', but it failed with the following errors

This brings up a couple of questions.

What boot script? I think I saw a reference to one that we placed
in our U-Boot tree in one of your patches, but I'll need to spend some
more time with that.

Why two partitions? It seems that unless a RAM disk is used, a
single partition should suffice. The same is true of SABRE Lite,
but I just noticed that the Freescale default environment only
supports FAT for some reason :(.

It's been a long day. I'll look at this some more tomorrow.

Regards,


Eric

Does that work if you do bibake u-boot-script-boundary before building

Thanks Eric,

That allows things to work, so it seems we have a missing dependency.

We still have an issue though. The generic boot script in our git
repository has a couple of references that presume a single
partition:

	https://github.com/boundarydevices/u-boot-imx6/blob/production/board/boundary/nitrogen6x/6x_bootscript.txt#L56

In particular, the 'root=/dev/mmcblk0p1' clause and the 1 in the
command:
	${fs}load mmc ${disk}:1

The SD card created by bitbake is configured for two:

	~/yocto/build$ fdisk -l 
tmp/deploy/images/fsl-image-test-nitrogen6x-20121211024022.rootfs.sdcard
	...
	Device Boot      Start         End      Blocks   Id  System
      ...sdcard1            8192       24575        8192   83  Linux
      ...sdcard2           24576      753663      364544   83  Linux

It trivially easy to create a boot script specifically for Yocto
images, but this should probably be discussed.

Why should we use two partitions? It seems that unless we're loading
a RAM disk, there's no benefit in having multiple partitions.

I suspect that there's a way to create a RAM disk in Yocto, but
I'm not sure where to start besides Googling the MLs and grepping
the sources.

If we decide to use a single partition, it also seems that the
.sdcard target is a bit of overkill, and a tar-ball of the RFS
is sufficient.

Regards,


Eric

I see; please try to boot u-boot-script-boundary package and try again. It
should work then.

The sdcard generation routine works this way and I'd like to do minimal
changes on this, if possible. Currently the change I am doing is to have
the boot script in the first partition. Maybe we'd need to patch the boot
script to be able to load kernel and pass the right root param, but rest
should work fine.

build u-boot-script-boundary before building the image.

I'll fix it for a v2.

We can apply a patch in the script for it. Can you please generate a patch
to adapt the script for our environment?

The real benefit here is to avoid too much complexity in sdcard class. For
accomplish it in a single partition we'd need to flexibilize the class even
more and I am not sure it is worth the effort.

The idea to provide a sdcard image is to allow for easier test and use of
the build images. It is a matter of dd the fine, directly in the sdcard and
be done with that.

I have no problem building 6x_bootscript_yocto and adding it to our git
repository. I think this will require a bump in the revision.

Do you want to keep uImage in the root of the first partition, and
format that as FAT?

Please advise,


Eric

Can do.

There's another issue though. The boot scripts need to be wrapped
by 'mkimage' so that U-Boot will 'source' them properly.

e.g.
	mkimage -A arm -O linux -T script -C none -a 0 -e 0 \
		-n "boot script" -d 6x_bootscript.txt 6x_bootscript


I just copied the SD card image and found that the .txt files
were copied, but not compiled.

Okay with me for now. At least this will get us up and bootable.

At least for now. I'd like to keep the change at minimum. We can refactor
and improve it later.

Right; so this needs to be done in u-boot-script-boundary. I will take a
look about how to do that.

Do you know the context (directory) in which the patch will be applied?

Will it be from the root of the U-Boot tree and patch
	board/boundary/nitrogen6x/6x_bootscript.txt
	board/boundary/nitrogen6x/6x_upgrade.txt

Or will it be applied somewhere in the work directory?

Also, the 6x_upgrade script is useless unless we copy u-boot.imx
into one of the partitions. Should it go into the FAT partition or
the ext3 partition?

Please advise,


Eric

I left it in deploy if someone wish to take it. I don't want to install it
as it might put people at risk of breaking their board (even though the
u-boot source has been taken from your production branch).

Let's go for fat, by now.
