To: linux-arm-kernel
I'm having difficulty getting a PandaBoard ES rev. B1 to boot v3.12 and
linux-next (30121118). I'm booting with a brand new u-boot
(c2e5e802ecb7ab668ce9911b210ed68c804b349f).
In both cases the device appears to hang shortly before one would expect
init to start as seen in the boot output below. I'm booting with the
omap4-panda-es devicetree. As far as I can tell, the machine is
completely dead and will not respond to even sysrq. I have a PandaBoard
A4 which apparently has no trouble with the same kernel image.
The only issues I can see in the output are,
* pinctrl issues pertaining to wl12xx[1], these shouldn't cause the
machine not to boot
* Various missing vmmc regulators
* hw-breakpoint issues:
* Failed to enable monitor mode on CPU 0
* CPU 0 failed to disable vector catch
These sound serious and occur near the hang. Perhaps this is the culprit?
Any help would be greatly appreciated.
Cheers,
- Ben

Do you have the same version of u-boot in both cases?

Which defconfig are you using ?
Can you see if CPU_IDLE is enabled in your defconfig?
I saw a similar failure on my panda es when CPU_IDLE is enabled.
If this is the case for you please apply this[1] patch and give a try.
Hope this helps. Let me know if you need more info.

Thanks and regards,
Lokesh

I derived the config from RobertCNelson's Debian Wheezy image. It did
require some modification, however.

Yes, CPU_IDLE is enabled.

Indeed that did the trick. Thanks for the reference!
I do however now see periodic messages of the form,
[ 42.143005] gic_timer_retrigger: lost localtimer interrupt
Any idea what this might be due to?
Cheers,

Hi,
I also try to boot v3.12 on my pandaboard rev A2, but it hangs at
"starting kernel". My SD card is originally loaded with a linaro 12.04
ubuntu-developer image. I have tried with v3.7 and v3.8 uImage and
both of them work normally, but v3.12 hangs. Is there any trick I
missed? Do I need to use the new u-boot as used by Ben?
And here is a separate problem with building u-boot. I cloned the
upstream u-boot repository. The latest commit is
c2e5e802ecb7ab668ce9911b210ed68c804b349f. Then I did:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4_panda_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j8
cp MLO u-boot.img /media/boot/
But when turn on my pandaboard, there is NO output from the serial
console. I didn't change the other file in the boot partition. They
are from linaro 12.04 ubuntu-developer image.
Any help would be much appreciated!

I've written up some of my experiences bringing up 3.12 on the
PandaBoard here[1]. You may find it helpful. Regardless, I would
definitely try upgrading u-boot.

I would check that you have earlyprintk enabled (both in the kernel
configuration as well as on the kernel command line). Moreover, ensure
that the correct serial devices is selected for low-level debug output
(in the kernel configuration).
Cheers,

Nice investigative blogging :)
Care to also update it with the other issues remaining on pandaboard?
Sounds like we're pretty close to having things working nicely with
mainline kernel on it, so let's just fix those issues ASAP.
I'm aware of at least two issues:
1. The WLAN not working after a soft reset, or if the interface is
reset with ifconfig down. This could be a typo somewhere in the
.dts file for the WLAN regulator or something like that.
2. Suspend and resume does not wake-up from serial console and spews
a bunch of warnings. The wake-up issue can be fixed with the new
the new interrupts-extended property to use the wake IRQs, I'll
try to update my patches for that today.

I wonder if we also have some dependency to some earlier versions of
u-boot as u-boot now only muxes the essential pins?

Yes, although frankly I've more or less given up on the wl12xx. This is
really a matter for linux-wireless@ but for some reason I find that it
is terribly unreliable. It stay associated without a problem but for
some reason I encounter extremely long (>2 seconds) dropouts where no
traffic can get in or out. Nothing is logged so I really have no idea
how to go about debugging this. Ultimately Ethernet is fine for my
purposes anyways.

Thankfully this is for a build-bot so this should be a problem for me.
I'll mention these in the write-up.

I haven't been very careful in characterizing the behavior of various
u-boot versions (although I've tried several) so I'm afraid I can't say.
Thanks again for your help.

"I wonder if we also have some dependency to some earlier versions of
u-boot as u-boot now only muxes the essential pins?"
This is exactly the problem in my case. I added "#define
CONFIG_SYS_ENABLE_PADS_ALL" in u-boot/include/configs/omap4_common.h
and now there is output.
I guess the reason that the u-boot worked out-of-box for Ben but not
for me is that I missed some configurations in v3.12 kernel. I image
there is a config options that tells the kernel to take care of the
non-essential pins that used to be the responsibility of u-boot. Could
you confirm my hypothesis? And if so, could you kindly suggest what's
the name of the config option?
Thank you!

That would be CONFIG_PINCTRL_SINGLE=y for device tree based omaps.
But if we have the configuration missing for some driver in the
board specific .dts file, that won't help naturally. We do have
PINCTRL_SINGLE enabled in omap2plus_defconfig.

Tony

Thanks, Tony. I checked my .config and this option is enabled. FYI, I
raised this issue in u-boot mailing-list, too. It seems to be a bug in
u-boot and only happens to certain version of pandaboard. The name of
the thread is "No single character output after update to latest
u-boot on pandaboard"
