Here are some basic OMAP test results for Linux v3.8-rc4.
Logs and other details at:

    http://www.pwsan.com/omap/testlogs/test_v3.8-rc4/20130120122039/


Test summary
------------

Boot to userspace:
    Pass ( 9/11): 2420n800, 2430sdp, 3517evm, 3530es3beagle,
  	   	  3730beaglexm, 37xxevm, 4430es2panda, 5912osk,
		  4460pandaes
    FAIL ( 2/11): am335xbone, cmt3517 
  
PM ret/off, suspend + dynamic idle:
    Pass (3/3): 3530es3beagle, 3730beaglexm, 37xxevm

PM ret, suspend + dynamic idle:
    Pass (1/2): 4460pandaes
    FAIL (1/2): 4430es2panda

PM ret, dynamic idle:
    FAIL (1/1): 2430sdp


Failing tests: fixed by posted patches
--------------------------------------

Other:

* 2420N800: powers down 30 seconds after boot
  - Presumably due to missing CBUS patches for watchdog control
  - http://lkml.org/lkml/2012/9/3/265
  - http://marc.info/?l=linux-omap&m=135274739624125&w=2
  - http://marc.info/?l=linux-omap&m=135664195831104&w=2


Failing tests: needing investigation
------------------------------------

Boot tests:

* am335xbone: hangs after "Starting kernel"
  - Cause unknown
  - http://www.mail-archive.com/linux-omap@vger.kernel.org/msg82297.html

* 3517EVM & CM-T3517: boot hangs with NFS root
  - Likely some Kconfig, board file, and PM issues with EMAC
  - Longstanding bug

* CM-T3517: boot hangs with MMC root
  - Due to missing MMC setup in board file
  - http://www.spinics.net/lists/arm-kernel/msg211471.html

Boot warnings:

* 3530es3beagle, 3730beaglexm, 37xxevm: nand_scan_ident() warning
  - "at drivers/mtd/nand/nand_base.c:2861 nand_scan_ident+0xdb4/0xf90()"
  - http://marc.info/?l=linux-omap&m=135630897110185&w=2

* CM-T3517: L3 in-band error with IPSS during boot
  - Cause unknown but see http://marc.info/?l=linux-omap&m=134833869730129&w=2
  - Longstanding issue; does not occur on the 3517EVM

PM tests:

* 2430sdp: pwrdm state mismatch(dsp_pwrdm) 0 != 3
  - need to doublecheck wakeup dependencies

* 2430sdp: power domains not entering retention
  - Cause unknown

* 4430es2panda, 4460pandaes: pwrdm state mismatch on CAM, DSS, ABE

* 4460pandaes: pwrdm state mismatch on IVAHD, TESLA 

* 4430es2panda: CORE, TESLA, IVAHD, L3INIT didn't enter target state
  - Probably due to lack of reset code for M3, DSP, SL2IF, FSUSB
    per discussion with Tero Kristo
  - Likely dependent on the bootloader version
    - fails with 2012.07-00136-g755de79

* 3730 Beagle XM: does not serial wake from off-idle suspend when console
  UART doesn't clock gate ("debug ignore_loglevel")
  - Cause unknown
  - Not yet part of the automated test suite
  - Re-tested at v3.7; still failing:
    http://www.pwsan.com/omap/transcripts/20121211-3730beaglexm-3.7-pm-offmode-fail-debug.txt

Other:

* 4430es2panda: omap_hwmod: l3_instr: _wait_target_disable failed
  - Unknown cause; could be due to the lack of hierarchical enable/disable
    in hwmod code
  - Jon Hunter reports this does not appear with the same X-loader/bootloader
    on his 4430ES2.3 Panda, so could be ES-level dependent


Failing tests: needing local investigation (may be due to testbed issues)
-------------------------------------------------------------------------

Boot tests:

* AM335x Beaglebone: omap2plus_defconfig kernels don't boot
  - May be fixed now, pending retest:
    - http://marc.info/?l=linux-omap&m=135082257727502&w=2
  - Not yet part of the automated test suite
  - Nishanth Menon & Vaibhav Hiremath report that it works for them
  * May be due to an old U-boot with FDT support problems used here?
    Pending local investigation and re-test


Problems reported by others
---------------------------

* I2C intermittent failures on N900; can break boot
  - "omap_i2c omap_i2c.1: timeout waiting for bus ready"
  - Reported by Aaro Koskinen
  - http://www.spinics.net/lists/arm-kernel/msg216859.html

* 2420H4: reports "Could not set MPU rate to 4294MHz" on reboot
  - Reported and fixed by Jon Hunter
  - http://www.spinics.net/lists/arm-kernel/msg216121.html

Does anyone know when the BeagleBone support is going to be fixed in mainline ?

I've just tried the latest linux-next git, and no joy.

However, Matt's edma-dmaengine-am33xx-v5 branch on github seems to be working:-

Uncompressing Linux... done, booting the kernel.

Are we just waiting for Matt's DMA stuff to be accepted ?

Hi Mark,

I'm not sure what needs to be fixed. The only thing my edma dmaengine
series adds is new features (specifically, mmc and spi dma support).
I would suspect some boot problem specific to Paul's configuration
if it's hanging. I just booted current mainline with an
omap2plus_defconfig build on my bone a5 and it came up fine.

For the features I listed above, yes. Also Mark Greer's crypto patches
for AM33xx depend on that series as does a patch series (not ready yet)
that I have to support the Bone audio capes.

There's a dependency I'm working through in a separate thread on lkml
since the dmaengine edma series requires the proposed
dma_get_channel_caps() api...still discussing that implementation.

Yep, I also could boot 3.8-rc3 using ramfs, no problem.

Do you use appended dtb? The only different that jumped out at me first
Paul's reported hang is he uses appended dtb and I boot my boards with a
single uImage and multiple dtbs the traditional DT way.

No, not appended. I have a u-boot that supports dtb:

  U-Boot SPL 2012.10-rc1-00148-g4668a08 (Sep 30 2012 - 09:35:20)
  U-Boot 2012.10-rc1-00148-g4668a08 (Sep 30 2012 - 09:35:20)

and using the omap2plus_defconfig, with a minicom script like the one
below, and it works just fine.

HTH,
Richard

It also works here. I have noticed issues with nfs boot and recent
mainline when powered from the USB cable though. I suspect we're getting
close to the power limit.

Hi guys,

Regarding the AM33xx test failures with appended DTBs, it would be very 
helpful if especially the TI people could try reproducing the problem.
Otherwise it's going to cause problems with merging any new AM33xx 
patches, since I won't be able to test them without additional work.  
Plus, this is something that used to work up until d01e4afd, so something 
isn't right.

You'll need to use the bootloader that TI originally shipped with the 
BeagleBones:

U-Boot 2011.09-00009-gcf6e04d (Mar 08 2012 - 17:15:43)

This is because many folks don't replace their bootloader.  I do plan to 
add a test with a recent version of u-boot, but the kernel should not be 
dependent on the bootloader in any way to work correctly.  If it is, then 
we need to document what u-boot version the kernel started to work with.

The Kconfig that I use is here:

http://www.pwsan.com/omap/testlogs/test_v3.8-rc4/20130120122039/build/am33xx_only/am33xx_only

It's possible that there's something wrong with the Kconfig.  It's 
basically just omap2plus_defconfig, but with all OMAP support for 
non-AM33xx turned off, and with the appended DTB and ATAG compatibility 
options turned on.

Let's try to do this ASAP.  That way, if it's some bootloader dependency 
or bug in the kernel, some fix can be merged during the v3.8-rc series, 
which is rapidly drawing to a close.

FYI, my beaglebone came with a slightly different U-Boot:

U-Boot 2011.09-00000-gf63b270-dirty (Nov 14 2011 - 10:37:14)

But I have the same behaviour. Recent kernels work with a modern U-Boot,
but not the original. The build I'm doing is very similar to yours:

Just a guess, but there can be problems when the appended DTB crosses an
1MB boundary. See this mail for details and a patch:

True, but that doesn't seem to be the case here:
ls -la arch/arm/boot/uImage
-rw-r--r-- 1 peko peko 3945127 Jan 22 09:26 arch/arm/boot/uImage

E.G. far from the 1MB boundary.

Don't rely on that.  Remember, if the compressed image occupies the same
location as the decompressed kernel, the decompressor will copy the data
to a different location in RAM first - I think at RAM offset + 32K +
decompressed kernel size.

So yes, please try the patch in the link above.

Ok, but this is with the exact same kernel image loaded at the same

I did. No visible difference. Also not with changing the uImage load
address (2M/16M/32M from start of RAM).

I just re-built U-Boot from f63b270 and the kernel from 9a92841
using commands similar to Peter's and the kernel boots for me with
the appended DTB.

(For some reason U-Boot version string doesn't have the commit id
and I can't recollect what causes this)

Paul,

The commit-id of U-Boot that you have is not present in my local tree. Will
need to track down which tree your U-Boot came from before experimenting.

I just re-built U-Boot from f63b270 and the kernel from 9a92841
using commands similar to Peter's and the kernel boots for me with
the appended DTB.

(For some reason U-Boot version string doesn't have the commit id
and I can't recollect what causes this)

rootfs on MMC.

A dumb question... in your case what's the bootargs set? Note that the mainline
kernel for AM335x doesn't have MMC support yet and the default bootargs is set to
rootfs on MMC.

Yes ... I'm trying to boot from a rootfs on MMC:-

Kernel command line: console=ttyO0,115200n8 earlyprintk debug root=/dev/mmcblk0p2 ro rootfstype=ext2
rootwait

But I should get *something* from the kernel before it starts trying to access the rootfs ?

Kernel command line: console=ttyO0,115200n8 earlyprintk debug root=/dev/mmcblk0p2 ro rootfstype=ext2
rootwait

I understand that MMC is not in the mainline.

Aha ... I tried without EARLY_PRINTK and it now boots up to the point of rootfs access.

Here's something Kevin fixed but did not send it out before going to
a vacation. Can you give it a try with earlyprintk enabled?

Note that this does not help with no output early on, that sounds
like a bug configuring the DEBUG_LL port somewhere.

I think earlyprintk on AM335x has not been functional for a while [1].
Will the latest patches from you to enable multiplatform debug-ll be sufficient
to test this out? I am trying to track down the boot issues reported and just
want to be sure of the dependencies.

I could not track down U-Boot that you were using so I used the v2013.01 tag
for U-Boot. However, using your build configs for v3.7 and v3.8-rcX I got the same
observations i.e. v3.7 boots but others don't.

One difference that I found was that post v3.7 the configs that you are using have
CONFIG_EARLY_PRINTK set. Once I disabled that I was able to bootup v3.8-rc1/4
(didn't try rc2/3 but I suspect early_printk was the culprit there too).

I checked with Santosh on this and he mentioned that for DT-only boot, which AM335x is,
that's expected behavior.

Can you update your AM335x-only config to disable CONFIG_EARLY_PRINTK or just skip
earlyprintk option in the bootargs for now?

If you still have issues booting can you update your U-Boot to v2013.01 since things
seem to be working fine at this point.

I could not track down U-Boot that you were using so I used the v2013.01 tag
for U-Boot. However, using your build configs for v3.7 and v3.8-rcX I got the same
observations i.e. v3.7 boots but others don't.

One difference that I found was that post v3.7 the configs that you are using have
CONFIG_EARLY_PRINTK set. Once I disabled that I was able to bootup v3.8-rc1/4
(didn't try rc2/3 but I suspect early_printk was the culprit there too).

I checked with Santosh on this and he mentioned that for DT-only boot, which AM335x is,
that's expected behavior.

Can you update your AM335x-only config to disable CONFIG_EARLY_PRINTK or just skip
earlyprintk option in the bootargs for now?

If you still have issues booting can you update your U-Boot to v2013.01 since things
seem to be working fine at this point.

Vaibhav

I'll give this a try over the next few days.

If EARLY_PRINTK is known to be broken for DT boots, could you please put 
together a Kconfig patch that prevents either EARLY_PRINTK from being 
selected when a DT-only board is selected, or vice-versa?

Yes you should check with current linux next and select the DEBUG_LL
port manually.

This one should no longer be needed as we now use the machine_id
for board-generic.c for DT boot.

This alone won't work without multiplatform support. At least modifying
the Kconfig to use the new settings for OMAP2PLUS is needed.

Probably easiest to make sure it works in linux next first.

Verified on linux-next that selecting the right UART port gives a functional early_console.

Setting CONFIG_EARLY_PRINTK=n doesn't fix the problem I'm seeing.

I also tried building a v3.8-rc6 kernel with the old v3.7-rc config that 
was used before; no luck.

Let's try to identify and get rid of bootloader dependencies in the 
kernel.  They indicate that the kernel isn't initializing something 
appropriately, which could cause strange problems later.

And just tried this with u-boot v2013.01 on a BeagleBoard A6a, does not

Oh and it's worth noting that parts of u-boot v2013.01 don't work 
correctly on earlier BeagleBones, i.e. Ethernet booting.

Agreed. It could also be that the boot-loader is doing something crazy but
we do need to know what's the dependency.
