Should install u-boot and x-loader on IGEP

[Loïc Minier]

Hi

We now have x-loader and u-boot for IGEP in the hwpack, we should install them.

These weren't in the 10.11 hwpack, so we need to allow for the files to be missing.

An u-boot bug currently prevents this from being useful; bug #716540

Bye

[Guilherme Salgado (salgado)]

I thought this would be a bug against linaro-images as that's where we
define which goes in each hwpack, no? l-m-c will just install whatever
packages are listed in the hwpack's manifest...

[Loïc Minier (lool)]

The hwpack does have:
packages=linux-image-linaro-omap u-boot-linaro-igep0020 x-loader-omap3-igepv2 libertas-firmware wireless-tools wpasupplicant

I think it does get installed in the rootfs, but there is no u-boot flavor set, so it doesn't get matched?

[Guilherme Salgado (salgado)]

Oh, right, so the packages are already in the hwpack and installed in
the rootfs but IGEP's config doesn't tell l-m-c to copy the u-boot.bin
to the boot partition. (The x-loader's MLO should be handled correctly
for IGEP)

ISTM that all we need is to set uboot_flavor to "igep0020" in
IgepConfig, but as Loïc pointed out, we need to make sure that doesn't
break l-m-c with 10.11 images, which don't have the u-boot package
installed.

I'm demilestoning this bug, it was a nice target for opportunity, but it didn't happen timely.

An easier approach is to just implement this next cycle unconditionally for IGEP as it will have been two cycles with u-boot + x-loader included in the hwpacks

[Ricardo Salveti (rsalveti)]

Mattias, tried with hwpack v2, as described at https://code.launchpad.net/~rsalveti/linaro-images/hwpack.natty.linaro-igep, but got the following error while creating the image:

Traceback (most recent call last):
  File "./linaro-media-create", line 161, in <module>
    args.is_live, args.is_lowmem, args.consoles)

    "uboot_in_boot_part is set but not uboot_flavor")
AssertionError: uboot_in_boot_part is set but not uboot_flavor

This is caused because the assert is called at populate_boot even if we're using v2:
"""

                      boot_device_or_file, is_live, is_lowmem, consoles):

        if is_live:
            parts_dir = 'casper'
        uboot_parts_dir = os.path.join(chroot_dir, parts_dir)

        cmd_runner.run(['mkdir', '-p', boot_disk]).wait()
        with partition_mounted(boot_partition, boot_disk):
            if cls.uboot_in_boot_part:
                assert cls.uboot_flavor is not None, (
                    "uboot_in_boot_part is set but not uboot_flavor")
...
"""

With branch lp:~mabac/linaro-image-tools/igep-fix this error is gone, but then I noticed that the MLO is also not copied to the first partition, probably because IgepConfig defines it's own _make_boot_files, without calling install_omap_boot_loader.

With hwpack v2 the IgepConfig class shouldn't be used, so that code
shouldn't be triggered, suggesting that the bug is somewhere else.

At least, that's my understanding of what should be happening :-)

Thanks,

That's what should be happening, yes. That will be the reality RSN. ;)
I forgot that I identified one more thing that needs work which is
exactly this: "Consolidate _make_boot_files() which is still board
specific: TODO". Initially I thought this was semi trivial but I
must've missed that IgepConfig does not look like the others.

I don't mind fixing the Igep support even for V1, if that helps
getting it to work with V2, but the only requirement is that it should
still be able to work with previous hwpacks (copying x-loader/u-boot
should not be mandatory).

[Mattias Backman (mabac)]

I have merged the make_boot_files changes which allows x-loader to be copied for any board without being mandatory. Can you give it a try?

[Ricardo Salveti (rsalveti)]

Still broken for me, but because of another bug.

Call trace with current trunk:
`/tmp/tmpkA7QQp/u-boot/u-boot.bin' -> `/tmp/tmpEetHIm/boot-disc/u-boot.bin'
Traceback (most recent call last):
  File "./linaro-media-create", line 170, in <module>

    "No kernel found matching %s." % (cls.vmlinuz))
ValueError: No kernel found matching vmlinuz-*-linaro-omap.

This is happening because path is pointing to chroot instead of chroot/boot, because of the following change:
270 def make_boot_files(cls, uboot_parts_dir, is_live, is_lowmem, consoles,
271 chroot_dir, rootfs_uuid, boot_dir, boot_device_or_file):
272 + if cls.hwpack_format == HardwarepackHandler.FORMAT_1:
273 + parts_dir = uboot_parts_dir
274 + else:
275 + parts_dir = chroot_dir

uboot_parts_dir is basically chroot_dir + "boot", so it works fine with V1 but then with V2 it fails as it'll try to look for the kernel file at chroot_dir instead.

Why can't we just use uboot_parts_dir for both? (and the variable name seems weird, as it's nothing actually related with uboot).

Hi,

If you use the change that Mattias proposed for the hwpack config at

  https://code.launchpad.net/~mabac/linaro-images/hwpack.oneiric.linaro-igep/+merge/75989

then this should work.

We aren't assuming that things are found in /boot as we were burnt
recently by files moving to different directories, and explicit is
better than implicit.

Thanks,

James

Oh, true, didn't notice this merge proposal this morning when testing
l-i-t, thanks for the pointer.

Fair enough, will merge the branch at the hwpack tree and test it
again with current l-i-t trunk.
