[opensuse-arm] openSUSE on Beagleboard xM
Hi, I downloaded images from : http://download.opensuse.org/repositories/openSUSE:/Factory:/ARM/images/ for the beagleboard xM I managed to boot using this kernel and rootfs but I have no modules loaded and there is nothing in /lib/modules, so I can only use built-in drivers. The thing is I did not used initrd since I am not sure how to handle it. I think initrd has all the kernel modules. Could you tell me how to use the initrd with u-boot, please?

Ah, cool, thanks a lot for trying it out!

Yeah, most device drivers are part of the initrd. And since we use LVM for /, you definitely need an initrd.
Could you tell me how to use the initrd with u-boot, please?
If you just take the beagle image and directly dump it onto your board, it should load the kiwi initrd with our kernel automatically. IIRC things will break after reboot, because mkinitrd isn't fixed yet, but you should be able to properly boot up the image at least once.

I do not think it will work since there is no MLO nor u-boot.bin nor boot.scr script in the archive. If I dd files, it won't boot since it is not an image file (and there is no MLO). If I copy files (cp) it won't work since u-boot does not know about it. I need the kernel cmdline to boot properly. Any idea ?

Yeah, I still need to figure out why we generate 2 files :o. Also, you won't find MLO - it's directly written to offset 128kb on the raw image for us, since that allows us to be completely FAT-less :) Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

The -raw.tar image is usefull to get files and using those as we want. The .raw is very good to dd it. It is nice to be FAT-less but how do you handle update? Well, MLO and u-boot do not need lots of update. I do that: sudo dd if=LimeJeOS-openSUSE-Factory-ARM-beagle.armv7l-1.12.1-Build6.6.raw of=/dev/sdb where /dev/sdb is my µSD card. But I cannot boot anymore. Any idea? Do I need to format my card in a special way?

No, nothing. I think MLO is not found.
That is odd. Could you please try to rewrite MLO to offset 128kb on the sd card? If that doesn't work, maybe we should try to take a known-good x-loader and dump that on there. Unfortunately, we need x-loader with a special header for raw boot which usually isn't present with the FAT based MLOs. Do you have source code to an x-loader that you're sure works? Or could you try to use the MLO that you found on the SD card with a FAT partition?

Well, I noticed something funny! I dd the image and then repartitionned and reformat my SD card with 1 FAT partition and copy nothing and tried to boot and openSUSE MLO started: ************************************************************ Texas Instruments X-Loader 1.5.0 (Feb 6 2012 - 17:53:20) Beagle xM Failed to mount ext2 filesystem...

Very Strange.
Do you have source code to an x-loader that you're sure works? Or could you try to use the MLO that you found on the SD card with a FAT partition?
x-loader/MLO I use is here: *********************************************************** git clone git://gitorious.org/xloadomap3/mainline.git xloader cd xloader make distclean make omap3530beagle_config make CROSS_COMPILE=arm-none-linux-gnueabi *********************************************************** But openSUSE MLO seems to work.

Yeah, I still need to figure out why we generate 2 files :o. Also, you won't find MLO - it's directly written to offset 128kb on the raw image for us, since that allows us to be completely FAT-less :) The -raw.tar image is usefull to get files and using those as we want. The .raw is very good to dd it.
It is nice to be FAT-less but how do you handle update? Well, MLO and u-boot do not need lots of update. U-boot can still be updated and resides in /boot. Once monted on my PC I can also see MLO.
Yup, but it's unused :).
I do that: sudo dd if=LimeJeOS-openSUSE-Factory-ARM-beagle.armv7l-1.12.1-Build6.6.raw of=/dev/sdb where /dev/sdb is my µSD card. But I cannot boot anymore. Any idea? Do I need to format my card in a special way? No, it should just work like that. Do you get any output on the serial console? No, nothing. I think MLO is not found. That is odd. Could you please try to rewrite MLO to offset 128kb on the sd card? If that doesn't work, maybe we should try to take a known-good x-loader and dump that on there. Unfortunately, we need x-loader with a special header for raw boot which usually isn't present with the FAT based MLOs.
Well, I noticed something funny! I dd the image and then repartitionned and reformat my SD card with 1 FAT partition and copy nothing and tried to boot and openSUSE MLO started: ************************************************************ Texas Instruments X-Loader 1.5.0 (Feb 6 2012 - 17:53:20) Beagle xM Failed to mount ext2 filesystem...

So MLO (x-loader) from openSUSE is here and able to boot. Very Strange.
Do you have source code to an x-loader that you're sure works? Or could you try to use the MLO that you found on the SD card with a FAT partition?
x-loader/MLO I use is here: *********************************************************** git clone git://gitorious.org/xloadomap3/mainline.git xloader cd xloader make distclean make omap3530beagle_config make CROSS_COMPILE=arm-none-linux-gnueabi ***********************************************************
But openSUSE MLO seems to work.
Maybe the problem comes from partitions?

The C/H/S numbers reported by fdisk are mostly meaningless, they are a fiction made up by the scsi host adapter driver (e.g. usb-storage) and/or the partition layout and do not relate to the data on the device. The start sector 2048 is the only thing that matters here to some tools. The sdcard standard requires all devices to have a single FAT32 partition starting at sector 8192, while some ancient (broken) versions of xloader required the first partition to start at sector 63, which is what old versions of fdisk used to do ms-dos compatibility. With the two partition layouts above, the first one is halfway sensible, because it actually fits the entire drive into the C/H/S layout with 122* 62*1017 blocks. The second one is not strictly valid in some tools because larger than 1024 cylinders should only be used together with 255 heads and 63 sectors on devices that have more than 8GB. For a 4GB card, the most reliable layout would be 128 heads and 32 sectors, because that lets you align the partitions to 4 MB while also allowing fdisk to detect the layout (which it cannot do otherwise). This trick does not work for 8GB cards though. What I think we do in Linaro is to always force a 255*63*xxxx layout when creating the partitions and aligning the partitions to 4MB but not a cylinder boundary.

Hi,
The start sector 2048 is the only thing that matters here to some tools.

What I think we do in Linaro is to always force a 255*63*xxxx layout when creating the partitions and aligning the partitions to 4MB but not a cylinder boundary.
I think what we do in kiwi is close to that. the geometry information if not set by options is taken from what parted thinks about it. As this happens through loop devices when the image is build the faked geomtry used by the loop driver is always 255*63*xxxx. The start sectors are aligned to be %8 clean and the to the cylinder boundary. So far I did not had any trouble with that setup on 4G SD cards (did not try on 8G cards though). For MLO loading I think only the start address might matter... not sure The start sector is set to 2048 because it's the default :) It's possible to override that with kiwi --create ... --start-sector XX at build time of the image Regards, Marcus -- Public Key available gpg --keyserver gpg-keyserver.de --recv-keys 0xCCE3C6A2 ------------------------------------------------------- Marcus Schäfer (Res. & Dev.)

Aligning to 8 sectors is not going to help at all, that is much smaller than the normal erase block size (4MB) and also smaller than typical page sizes (8kb or 16kb). If you want good performance, you should always align to 4MB or more. Using the regular geometry (255/63/1024), that will never be cylinder aligned, which is ok. Don't try to do cylinder alignment.

No. My previous trick no more works. Well, I tried another thing. I dd if=/dev/zero to erase the first sectors to be sure to have a good card to start and then dd the raw image. Then I tried to boot and get a "60" on the serial port which means no suitable MLO where found where it is ecpected!

Yeah, that's in line with the document I was reading :) • Raw mode: In raw mode, an image can be at offset 0 or 128KB and must not be bigger than 128KB. Raw mode is detected by reading sector 0 and sector 256. The content of these sectors is verified for the presence of a TOC structure. In the case of a GP device, a configuration header (CH) must be in the first sector followed by a GP header. The CH can be void (contains only a CHSETTINGS item for which the valid field is 0), as described in Section 26.4.8.2, Configuration Header. Image data is read directly from continuous sectors of a card. If raw mode is not detected, file system mode is checked.
I think, there is a problem on the MLO file itself and maybe also on the MLO location for the raw mode.
Maybe we just need a different MLO for the xM beagleboard? Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

With openSUSE MLO it boots something (since it does not try UART boot, which print 60) but nothing is printed on screen (crash?). With the openSUSE sources and patches with a code sourcery toolchain, I get a running MLO. So, it should be a problem with the toolchain or some optimisations flag (which are not supported by beagleboard?). Could you please provide the full compilation line to see what flags could lead to problems? Or maybe did you use the pandaboard MLO instead of the beagle MLO? That could explain why it start to boot but crash. Note that u-boot.bin do not boot either.

With the openSUSE sources and patches with a code sourcery toolchain, I get a running MLO. So, it should be a problem with the toolchain or some optimisations flag (which are not supported by beagleboard?).
Very interesting. What I'm still not grasping is why you actually had a booting x-loader a while back.
Could you please provide the full compilation line to see what flags could lead to problems?
Oh, sure! The full build log is also available in OBS: https://build.opensuse.org/package/rawlog?arch=armv7l&package=x-loader-omap3beagle&project=openSUSE%3AFactory%3AARM&repository=standard
Or maybe did you use the pandaboard MLO instead of the beagle MLO? That could explain why it start to boot but crash.
Hrm. Could you please try and check by extracting the x-loader-omap3 rpm on another machine and diff it? :)
Note that u-boot.bin do not boot either. It seems I cannot download u-boot-linaro-20111213.tar.bz2 from https://build.opensuse.org/package/files?package=u-boot-omap3beagle&project=openSUSE%3AFactory%3AARM to try to build it. COuld you please tell me where I can download it?
Uh - just use osc :) $ osc co openSUSE:Factory:ARM u-boot-omap3beagle Thanks a lot for debugging this! Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

No. My previous trick no more works. Well, I tried another thing. I dd if=/dev/zero to erase the first sectors to be sure to have a good card to start and then dd the raw image. Then I tried to boot and get a "60" on the serial port which means no suitable MLO where found where it is ecpected! Hrm - weird.

Yeah, good point. We already use SPL for the Panda, but somehow didn't manage to get the OMAP3 x-loader also based on it. I honestly don't remember why. But given the new issues, we probably should give it another try :). I'll try to hack on this in a spare minute.

Just tried to compile u-boot with SPL and it is 329K which is greater than the 128K limit for beagleboard (OMAP3/DM37x). So we have to use MLO+u-boot.

SPL is almost same as x-loader, just that it is built out of mainline u-boot sources.

Well - sector 0 contains the MBR, which usually doesn't look like a CH ;).
Maybe, there is a valid header there for some reason? RAW mode should be supported for both NAND and MMC/SD.
Yeah, and raw mode works for me on sector 0, but not on sector 256, which the spec also mentions as valid. Do you know anyone who could try and debug to run SPL on offset 256 in raw mode?

Oups, did only watch on u-boot.bin, not u-boot-spl.bin sorry. I thought we get only one file and save 1 stage but it does not. 128K limitation is due to ROM boot loader of OMAP3/DM37x SoC.
What is the difference between SPL and MLO? Is it just an include of x-loader/MLO in u-boot? Maybe some improvments?
SPL is almost same as x-loader, just that it is built out of mainline u-boot sources. So, you can pick and choose anything available in u-boot to create a tiny first stage bootloader which is called SPL.
Aneesh, I have a very strange effect now. If I take our MLO binary and dd it onto the disk at offset 128kb, the bootrom doesn't find anything. Putting it on sector 0 works. With the exact same binary.
Could you please verify if you can see similar effects on OMAP3? Is raw boot supposed to work there?
I don't have easy access to OMAP3 boards anymore. But did you try erasing the flash at offset 0.
Well - sector 0 contains the MBR, which usually doesn't look like a CH ;).
Maybe, there is a valid header there for some reason? RAW mode should be supported for both NAND and MMC/SD.
Yeah, and raw mode works for me on sector 0, but not on sector 256, which the spec also mentions as valid.
Do you know anyone who could try and debug to run SPL on offset 256 in raw mode?
Ouch. After a further bit of debugging, I managed to narrow it down: $ dd if=/dev/urandom of=/dev/sdc bs=1 count=4 That breaks the raw boot. If instead, there are zeros, it works. Now 2 questions arise from this: 1) Why do we have anything in the executable area of the MBR on ARM? What is this code? 2) Why does the bootrom behave differently based on the executable area? Shouldn't it just search for the CH and if it can't find one, pass on?

Yeah, maybe the bootrom code doesn't check for the magic properly :). The same thing works just fine on OMAP4, so it's got to be something fishy in the old SoCs. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

I tried the latest raw image (beagle build 10.3) and it is booting fine. Thanks. I will test it a bit further (audio, video, etc...) when I will have some spare time.

Hi,
Or maybe did you use the pandaboard MLO instead of the beagle MLO? That could explain why it start to boot but crash.
ARGH. MARCUS!
Yes, you're right. Marcus changed the kiwi description to use the panda bootloader :(((. Of course that won't work...
Sorry guys all my fault :( It's fixed now. I changed the description to fit for my panda board but forgot to change it back.

If I dd the new raw image to my SD, it does not boot but if I take your new MLO and dd it to my SD, MLO boots but do not find any partition, since my dd overwrited the partition table (or something like that since openSUSE do not report any partition anymore after my dd). How do you create the raw image? I mean where do you dd the MLO? I think obs/kiwi is doing it automatically but there should be a config file somewhere.

Hi,
Aligning to 8 sectors is not going to help at all, that is much smaller than the normal erase block size (4MB) and also smaller than typical page sizes (8kb or 16kb). If you want good performance, you should always align to 4MB or more. Using the regular geometry (255/63/1024), that will never be cylinder aligned, which is ok. Don't try to do cylinder alignment.
Ok makes sense, I'm going to change that in kiwi. Thanks much But I guess this is not related to the initial boot problem Thanks Regards, Marcus -- Public Key available gpg --keyserver gpg-keyserver.de --recv-keys 0xCCE3C6A2 ------------------------------------------------------- Marcus Schäfer (Res. & Dev.)
