Which version of uboot is recommended for Beagleboard-XM (kernel 3.11.10)?

Hi,

I have been using kernel 2.6.32 for years and decided it was time to upgrade to a more recent one so I chose the following as it can run the board safely at 1GHz:

https://github.com/RobertCNelson/armv7-multiplatform (v3.11.x branch)

I also had to upgrade u-boot as my version (U-Boot SPL 2013.01-00071-g6ad77d8 (Feb 01 2013 - 22:10:08)) does not support zImage (even if I rebuild it with CONFIG_CMD_BOOTZ set it refuses to boot a zImage). So I switched to u-boot-2014.1.

Whilst it booted first time the USB ports do not come up (and there are a bunch of errors during boot). I suspect this is a u-boot problem since if I boot my known working 2.6.32 kernel with uboot-2014.1 the usb ports are not working either. (If I go back to old uboot with 2.6.32 everything works fine so I know the board is good).

Is there a known stable version of u-boot for beaglexm that can boot a zImage for this kernel? Do I need some patches for uboot?

Thanks,
Mark

Hi,

I have been using kernel 2.6.32 for years and decided it was time to upgrade
to a more recent one so I chose the following as it can run the board safely
at 1GHz:

technically it's still not "safe" see Nishanth's response when i asked
him yesterday about it..

https://lkml.org/lkml/2014/1/29/446

GitHub - RobertCNelson/armv7-multiplatform (v3.11.x branch)

btw: v3.11.x/v3.12.x isn't really being testing anymore, care to jump
on v3.13.x while it's stable? :wink: (plus usb is now built-in with
v3.13.x and works when built-in)

I also had to upgrade u-boot as my version (U-Boot SPL
2013.01-00071-g6ad77d8 (Feb 01 2013 - 22:10:08)) does not support zImage
(even if I rebuild it with CONFIG_CMD_BOOTZ set it refuses to boot a
zImage). So I switched to u-boot-2014.1.

Whilst it booted first time the USB ports do not come up (and there are a
bunch of errors during boot). I suspect this is a u-boot problem since if I
boot my known working 2.6.32 kernel with uboot-2014.1 the usb ports are not
working either. (If I go back to old uboot with 2.6.32 everything works fine
so I know the board is good).

Is there a known stable version of u-boot for beaglexm that can boot a
zImage for this kernel? Do I need some patches for uboot?

Here's my patch against v2014.01

It's expecting:

fat directory: /dev/mmcblk0p1
zImage
/dtbs/omap3-beagle-*

root: /dev/mmcblk0p2

Thanks,
Mark

yep - so it is.. I am more than happy to guide folks if anyone is
interested in pitching in as we work with upstream in the parcels
needed.

in fact, this is not just an OMAP3/beagle only issue -> I have had to
state precisely the same here:
https://bugzilla.kernel.org/show_bug.cgi?id=58541

As the default beagleboard kernel patchset wrangler, I can help out
where i can. (plus i have lots of beagle-xm generations running for
testing)

I have those 6 patches you've posted so far, in my v3.14-rc0 tree i'm
prepping for users.

Regards,

5

Thanks for your responses.

I will try the stable v3.13.x tonight (although I still suspect my u-boot is not setting up the board properly in the first place).

Mark

Sorry, just noticed you linked to a uboot patch as well. Will try both.

Mark

Thanks - the following are usually helpful, considering that all
developers do not have all board variants:
a) usually a tested-by/acked-by on the list is most helpful to move
those patches forward.
b) new series like DSS dt converstion etc - if folks could add
reviewd-by/acked-by/tested-by, it will help us move those forward as
well.
c) if folks could ensure latest linux-next tag and master tags are
sane and report issues - that'd help as well - mostly coz, some
trivial changes like
http://marc.info/?t=139059076500002&r=1&w=2 break platforms from time to time :frowning:
d) if folks would like to pickup any kernel feature and upstream as
well, we are more than happy to help along too. - especially with the
device tree conversion - many drivers need revamp - we are trying to
do this but our pace can greatly be helped by additional community
participation as well :).

Regards,
Nishanth Menon

Great! u-boot 2014.1 with the patch above and kernel 3.13.1-armv7-x9 worked first time. Usb camera and usb serial convertor show up in /dev now.

Remaining problems are:

  1. usb0 not working - it comes up after “ifconfig usb0 up” and “ifconfig usb0 192.168.0.20” both work, but the LEDS do not come on and no data is sent. Do I need a special driver for this? lsmod only shows:

  1. rootfs is mounted read-only - I thin I can change this in uboot?
  2. and of course, the rtl8192cu driver doesn’t work (but it never has - I always need to build realtek’s version from their website - however, they do not seem to have a version which supports 3.13 :frowning:

Nishanth - I would be glad to give whatever information is helpful but being a newbie I am not clear about some of the terminology you use e.g. “ensure latest linux-next tag and master tags are

Odd, as i just had a user report the musb port was working on the older beagle..

2. rootfs is mounted read-only - I thin I can change this in uboot?

I'm guessing Angstrom? (the u-boot patch default to ro for ubuntu/debian)

add to uEnv.txt:

mmcroot=/dev/mmcblk0p2 rw

3. and of course, the rtl8192cu driver doesn't work (but it never has - I
always need to build realtek's version from their website - however, they do
not seem to have a version which supports 3.13 :frowning:

Use Atheros. :wink:

Hi Mark,

Nishanth - I would be glad to give whatever information is helpful but being
a newbie I am not clear about some of the terminology you use e.g. "ensure
latest linux-next tag and master tags are
sane and report issues".

Apologies on not being clear:
in the upstream world, two kernels are of significant importance:
1. origin git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
obviously..
2. linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
This one is a daily integration tree of every maintainer tree -
towards a merge window this tends to represent approximately how the
next linux kernel rc1 will look like -> for example next-20140131 is
today's linux-next tag. It is pretty close to what v3.14-rc1 will
eventually look like -> ofcourse things are changing continually in
various maintainer branches, and keeping an eye on daily status is of
interest to folks.

kernel.org tag (or tags in torvald's tree) such as v3.13-rc1, ...
3.13, upcoming 3.14-rc1 etc are the baselines we really want to ensure
working and feature rich. in order to do that, ensuring every such tag
(including rcs) be regularly monitored to ensure things are good and
report issues.

I mean, even if folks dont have a daily cronjob (similar to what I
have for 15 boards), it is still nice to get regular pokes on
linux-omap mailing list asking for status of certain features like how
Robert did for 1GHz. that keeps the rest of us ensuring things work
for everyone else folks start thinking that these platforms are not of
significant interest and tend to feature-rot(die out) over time..

Nishanth Menon

Odd, as i just had a user report the musb port was working on the older beagle…

https://github.com/RobertCNelson/netinstall/issues/24

Turns out I needed to add smsc95xx to /etc/modules and bring up eth0 not usb0 to make ethernet work.

Use Atheros. :wink:

I don’t think it supports rtl8192cu, will have to find a new adaptor that is compatible with Atheros drivers.

thanks,
Mark

FWIW, last time I tried this trick there is some magic required to get
the musb port to work in u-boot - I think just using the older musb
driver will get you most of the way.

  If you're sufficiently interested, mail me off-line and I'll dig around
and give you some hints, but you seem to have been looking for the
EHCI USB anyway ..
