[Buildroot] Repair boot from SD card on i.MX6 Sabre boards

[Buildroot] Repair boot from SD card on i.MX6 Sabre boards

[Vincent Stehlé]

Hi,

Here is a two-patches series, to repair the boot from SD card on
Freescale Sabre boards.

The first patch adapts the SD card creation script to the new versions
of sfdisk; a prerequisite to actually preparing an SD card and booting
from it.

The second patch switches the defconfigs to building a zImage instead of
an uImage, to reflect what u-boot in Freescale releases awaits nowadays.

This was build-tested for all the five touched defconfigs but I did only
verify the boot on i.MX6 quad Sabre AI.

Feedbacks and testers welcome!

Best regards,

V.

[Buildroot] [PATCH 1/2] board/freescale: refresh create-boot-sd.sh

[Vincent Stehlé]

Starting with version 2.26, sfdisk defaults to a unit of 512 B sectors.
With those recent versions of sfdisk, the create-boot-sd.sh script ends
up creating a boot partition of 240 KB, which is too small to contain a
Linux kernel.

Version 2.25 of sfdisk and older defaulted to cylinders; a
media-dependant unit, typically much larger than 512 B. With those
versions the create-boot-sd.sh creates paritions, large enough to hold a
kernel.

We update the create-boot-sd.sh script to use the more readable and more
stable named-fields sfdisk format for the partitioning command, and set
the boot partition size to 64 MB, which should be enough for everyone.

Is the "MiB" suffix supported on older sfdisk releases? Ubuntu 14.04
ships sfdisk 2.20.1, and its manpage does not contain "MiB".

If that is not supported, then I guess "--unit M" should work. It's in
the manpage, but I haven't tested it yet.

I strongly think we should support the latest Ubuntu LTS, AFAIK it's
widely used by embedded Linux developers.

 We should also still support Ubuntu 12.02 IMHO and even older RHEL.

 So to avoid this kind of issue, it would be better to use genimage. But that's
a much bigger change, of course.

What about parted instead of sfdisk? Seems to be more consistent across the
different releases.

[Buildroot] [PATCH v2] board/freescale: switch create-boot-sd.sh to parted

[Vincent Stehlé]

Starting with version 2.26, sfdisk defaults to a unit of 512 B sectors.
With those recent versions of sfdisk, the create-boot-sd.sh script ends
up creating a boot partition of 240 KB, which is too small to contain a
Linux kernel.

As it is difficult to address both pre and post v2.26 sfdisk versions in
a single command, we change the create-boot-sd.sh script to use parted
instead. While at it, we set the boot partition size to 64 MB, which
should be enough for everyone.

Hi,

This is a second proposal, using parted this time. Even with sfdisk
`--unit' parameter, I could not find an eleguant solution to support all
versions of sfdisk, sorry. Please let me know if you find switching to
parted acceptable.

This is tested on Sabre AI with an i.MX6 Quad.

Best regards,

V.


Changes in v2
-------------
- Switch to parted, as advised by Gary.
- Fix spelling in commit message, spotted by Luca.

You should mention in the relevant readme.txt files under board/freescale/ 
that parted needs to be installed on the host.

Alternatively, you can enable host-parted in the config files, and use that in 
create-boot-sd.sh.

 I really don't like that we would rely on a tool installed on the host.

 Is there any reason why genimage (cfr. wandboard) wouldn't work, like I
suggested earlier?

Hi Arnout,

You are right, genimage seems like a nice solution. In fact I think I
prefer this SD card image generation approach over the direct SD card
modification method.

Thank you for this suggestion.

Best regards,

V.

[Buildroot] [PATCH 2/2] imx6sabre: use zImage format for kernel

[Vincent Stehlé]

Starting with u-boot rel_imx_3.10.53_1.1.0_ga, the default is to boot a
zImage instead of an uImage. Update the i.MX6 defconfigs accordingly.
This repairs the boot from SD card.

While at it, align freescale_imx6sololiteevk_defconfig a bit more on the
other i.MX6 defconfigs, update documentation and SD card creation script
comments to reflect the change to zImage.

> Here is a two-patches series, to repair the boot from SD card on
> Freescale Sabre boards.
> 
> The first patch adapts the SD card creation script to the new versions
> of sfdisk; a prerequisite to actually preparing an SD card and booting
> from it.
> 
> The second patch switches the defconfigs to building a zImage instead of
> an uImage, to reflect what u-boot in Freescale releases awaits nowadays.
> 
> This was build-tested for all the five touched defconfigs but I did only
> verify the boot on i.MX6 quad Sabre AI.

> Feedbacks and testers welcome!
