GoflexNet: can not boot from SATA with kernel linux-4.2.0-kirkwood-tld-1-bodhi.tar.bz2

Hi all.

first of all sorry for the lengthy post, but I have no idea how to cook it down.

A while ago I modded my GoflexNet according to Jeffs description ending up with a kernel from Linux-3.11.1-kirkwood-tld-1
(after fruitlessly trying to get a self compiled one working) and an appropriate initrd booting a Gentoo rootfs on sata port 0
(ext3@/dev/sda1).
I have a serial console hardwired, so accessing UBOOT is no Problem.

Problem was I also have a data partition (btrfs) and the harddisc at the second SATA port.
Since the btrfs tools are (by now) much newer than the kernel, I run into problems after balancing the btrfs. Those should be fixed with a newer kernel.

I upgraded UBOOT (http://forum.doozan.com/read.php?3,12381) and then the kernel (http://forum.doozan.com/read.php?2,12096).

The UBOOT upgrade went fine.

For the kernel i prepared 2 kernels (method 4a) and 4b)) and upgraded my initrd.
Unfortunately both kernels do not boot from SATA, the kernel does not even init the SATA and therfore can not find the rootfs and panics.

Fortunately I made a backup of the old kernel+initrd, so i can still (manually) boot the old kernel.

Here is the backup version manually booting (already with the new UBOOT):

(ethaddr is set as well as all default env settings. I know this is not the recommend way to boot but a the moment it boots the backup kernel in a reliable way. once the new kernel boots from sata, i switch back to a proper env. except someone tells my i need a certain env setting to allow the kernel to detect the sata.)

the initrd 'just' contains a copy of /lib/modules and for reasons I forgot also the stuff normally going to /boot (zImage, System.map, etc...)
and may not be needed at all. (too tired for experiments now. i needed it at some stage for the old kernel and left it at that. just upgraded to newer modules)

except for the unusual big initrd i can not find any reason why sata would be expected to not be working

Any thought is welcome!

Enno

Enno,

> my env is a hopeless mess now.

It is :) I would not even attempt to fix it.

What you should do is boot into the rootfs that you still can boot. Save the current envs to a text file (in case you want to reference it). And then flash the default u-boot envs (you did this during u-boot installation). The default u-boot envs will allow you to boot with SATA rootfs without changing anything.

Note that the SATA rootfs must be prepared exactly as the rootfs thread stated (single partition Ext3). And:

- u-boot requirements r1-r4 for "B. Flashing default u-boot envs image" section must be satisified.
- Use 4a to boot with DTB file.

After you are running OK, then worry about Ext4. It is really quite simple to transition to Ext4 from an existing running system.

Hi bodhi,

thanks for all your effort you put into this.

EXT4 and a cleaned env don't concern me now.

Problem is not that UBOOT does not find the kernel, but that the kernel does not try to init the sata (and therfore can not access sda1 and panics).

I have backups of my env, so I'm not so reluctant to try/mod something.

I just tested a few variations:

• stripped down env with the device and partition for the kernel files hardcoded. this reliably boots the 3.11 kernel which detect sata and all is good. trying to boot the 4.2.0 kernel works up to the point where the kernel is loaded, does NOT init the sata and then panics.
  (tried method 4a and 4b)
• the uboot-default env ("env default" command) this only searches usb so does not find the kernel. If I mod the 'usb' parameter to 'ide' and insert an 'ide reset;sleep 3' before scanning the devices, it finds the kernel and the kernel fails to init the sata.
• the env from before the uboot upgrade. i expect this to work with method 4b). It boots Jeff's recovery system (a 2.6-something kernel with the rootfs inside the flash) (the backup may not be as recent as i thought)
• the default env from uboot.2014.07-tld-3.environment.bodhi.tar with obvious adoptions (ethaddr, ipaddr, load adress of the dtb file)
  This finds the kernel on the correct device, loads it, boots it and then the kernel fails to find the sata.

Here is the bootlog (using recommended default env):

(actually I'm not too happy with the root=LABEL=rootfs part, I like to be explicit and would rather specify /dev/sda1 here. But I can not imagine this to be the showstopper here.)

Even with this envs, I can still manually boot the bakup kernel with these lines:

GoFlexNet> ide reset
GoFlexNet> ext2load ide 0:1 0x800000 /boot/bak/uImage
GoFlexNet> ext2load ide 0:1 0x1100000 /boot/bak/uInitrd
GoFlexNet> run set_bootargs
GoFlexNet> bootm 0x800000 0x1100000

and this one finds the sata and boots from sda1 as expected. But the 4.2.0 does not work ... Shall I try a different version?

clueles,

Enno

Hi bodhi,

just to be precise:
There is one partition on disk sda => sda1
sda1 has a label of rootfs and is of type ext3
in this partition resides the rootfs and contains /boot/uImage and /boot/uInitrd symlinks pointing to the files-to-be-used inside /boot.
also I have a backup of /boot (from before i started trying to upgrade) which is stored in /boot/bak/
(so there is a symlink /boot/bak/uInitrd pointing to the uIninitrd-3.11-something.. in the same directory)
so requirements r1..r4 are fulfilled.
(there is a second disk (sdb) which contains a stale backup of the rootfs (with /boot empty) and a data partition as btrfs).

I do not think the symlinks are part of the problem (I like them, because they (in principle) allow to select the kernel-to-be-booted from the running os, no need to meddle with the serial console.)

coclusion so far:
- no matter what mess or version of envs I use, it can load the kernel, but the 4.2.0 kernel fails to init the sata, whereas the 3.11 kernel works.
- newer uboot allows to load dtb files and boot kernel with this information (no need to embed the dtb)
- 4a vs. 4b does not seem to matter, both do not detect the sata
- the 3.11 kernel (no dtb) (as far as i remember) uses arcNumber=3089 to know if it should search for sata
- is there a new env variable doing something similiar for dtb kernels?
- except for machid, arcNumber and bootargs: are there further env vars which magically influence the loaded kernel upon bootm ?
- when i try to load the 3.11 kernel without initrd, it fails to detect sata. why? did i mess up some magic inside when exchanging the 3.11 kernel parts with 4.2.0 kernel parts in the initrd? (everything else I left as it was...). especially interesting since the bootargs do not imply any USE of the initrd (I would expect root=/dev/ram0 to initially start booting from the initrd, but root=/dev/sda1, so initrd is not used explicitly. Is it maybe still used to, say, load a module or two in an implicit way? But why does it fail to do so when the modules are all there?)

frustrated.

Enno

Enno,

You are making it way too complicated than it should be!

> Is there anything magic inside the initrd which i may have broken?

There is no magic in uInitrd at all! The reason you're having booting problem: multiple partitions without proper setup. See this post for explanation:
http://forum.doozan.com/read.php?3,19093

Forget about your btrfs for now. Get it boot with a single disk drive, singe Ext3 partition with rootfs label. This is quite simple if you leave the u-boot default envs intact after flashing it. (Note that what you said above "env default" was not what I meant by u-boot default envs which was set by flashing the default envs image). The necessary changes are ethaddr, dtb,.. that were described in the installation instruction.

After you can boot with a single disk, single Ext3 partition as instructed in r1-r4, come back and I'll help you continue to boot with the second disk with btrfs.

you are right that the neither the second disc nor the btrfs are part of the problem, so I physically removed the second disc.

setup is now: one disc with one partition (which is ext2 (no journal)) labelled "rootfs".
containing my rootfs and under /boot has uImage and uInitrd fitting to your kernel image 4.2.0-kirkwood-tld-1

Again, uboot finds the rigth/one partion, loads the kernel, the kernel starts up, but does not try to init the sata.

any thoughts?

Enno

1. You still did not have ext3 partition
2. And are you sure the partition label is rootfs ?

If after you made sure the above were correct and it stil did not boot, then interrupt serial console and get the listing of u-boot envs

printenv

and post here.


Further thought, have you tried to boot with USB and then plug in the SATA HDD?

Hi bodhi,

I just converted the rootfs partition to ext3 to exclude this to be a problem.
Still the kernel does not try to detect the sata.

There is exactly one disc with exactly one partition which is also a primary one and it is the first one (p1) and is of type ext3
(would a fdisk screenshot help to clarify?)

I'm pretty sure the partition is labelled rootfs.

/dev/sda:  DOS/MBR boot sector; partition 1 : ID=0x83, active, start-CHS (0x0,1,1), end-CHS (0x3ff,255,32), startsector 32, 62586848 sectors
/dev/sda1: Linux rev 1.0 ext3 filesystem data, UUID=a02db894-e897-4911-b5aa-adf74cfafce1, volume name "rootfs" (large files)
goflexnet enno # blkid /dev/sda1
/dev/sda1: LABEL="rootfs" UUID="a02db894-e897-4911-b5aa-adf74cfafce1" SEC_TYPE="ext2" TYPE="ext3"

Also the problem is NOT about UBOOT not finding the right partition or not loading the (right) kernel. (well, there is only one)

The problem is about the KERNEL-4.2.0 not initialising sata during startup and therefore not finding any sata partitions (well, there is only one).
(whereas the 3.11.1-kirkwood-tld-1 works. but that didn't use devicetree files.)

My problem seems related to http://forum.doozan.com/read.php?2,12096,24412#msg-24412
but embedding the dtb file did not help in my case (unfortunately).

Output of printenv.

I highlighted my changes to the default uboot upgarde procedure from from http://forum.doozan.com/read.php?3,12381 using uboot.2015.10-tld-1.goflexnet.bodhi.tar for the uboot and uboot.2014.07-tld-3.environment.bodhi.tar for the envs. (both files are linked on that post)

The loading address of the dtb file is shifted from 0x1C00000 to 0x2F00000 to not overwrite my rather large uInitrd.
Except for magic memory barriers/holes this should be no problem
(Since the dtb file is small, i could also try to squeeze it else. any suggestions?)

still puzzled.

Enno.

I'll try tomorrow to put the kernel on an usb drive and boot from that. But I expect no difference.

Enno,

OK so we covered all bases upto the kernel booting.

I took a closer look at your dmesg boot log. Indeed it showed no SATA! This might be due to the SATA brand that you are using. I think booting with USB will be better to troubleshoot this problem.

- Use the basic rootfs as downloaded. Don't change anything.You mentioned your uInitrd is too big, this indicated your rootfs has been modified. This is very likely where the problem was.
- Make sure you are using the DTB for the GoFlex Net.
- Boot with USB while the SSD is plugged in, and if not successful, repeat while SDD is not plugged in.
- Look at dmesg to see if sata_mv driver is running and initialize this SSD at some point.

Hi bodhi,

thanks for looking at this.

I'm unsure if claiming an unusual sata device helps, as it boots fine with the 3.11.1 kernel.
regardless i tested an ordinary hdd (cloned my disc sector-wise), which gives the same results.

I promised to test booting via usb.
For this used an usb-to-sata converter to boot my disc via usb (so nothing is attached to sata).
the kernel loads but even fails to find anything at the usb side. (sata also gets not initialized).

UBOOT detects the rigth partition, loads the kernel and that fails to see usb OR sata....


I strongly suspect the kernel getting the wrong dtb information. as there a chance they get overwritten somehow after uboot loaded them to memory? I'm referring to lines like:

   Loading Ramdisk to 062af000, end 07b17410 ... OK
   Loading Device Tree to 062a9000, end 062aee78 ... OK

so Uboot is shuffling data around before booting the kernel.... if than the kernel finds an invalid dtb block, it may not know anything about sata/usb/gpio and stuff. (contra: the console is still working (up to the panic) , so it's either configured/detected in a different way or the dtb info is not fully corrupt.)

Then I downloaded the following files (from http://forum.doozan.com/read.php?2,12096):
Debian-3.18.5-kirkwood-tld-1-rootfs-bodhi.tar.bz2 and linux-4.2.0-kirkwood-tld-1-bodhi.tar.bz2
and prepared an usb-stick (/dev/sdc) with 1 primary ext3 partition labelled 'rootfs' and untarred the rootfs file there.

goflexnet / # blkid /dev/sdc*
/dev/sdc: PTTYPE="dos"
/dev/sdc1: LABEL="rootfs" UUID="0e630de5-af89-45ad-8564-7408868f4068" SEC_TYPE="ext2" TYPE="ext3"

Then I updated the kernel files according to that post (untarring in /boot, recreating uImage and uInitrd, etc...).

And it boots fine! (this also means that changing the loading address of the dtb file is no problem.)

Now I have a working reference!

So I copied my uImage /which was created from the same kernel image) to /boot and rebooted.
Again this works like charm. (as expected)

Using my uInitrd the kernel panics as the sata does not get initialized.

So the problem is my initrd.

any links on how this should look like to work?
(I'm going to dissect the differences anyway, but if it is known what needs to be there this would save some time.)

I'm unfamiliar with debian, thats why my rootfs is gentoo.
And I really would like to be able to boot my Gentoo system on my GoflexNet.

Again, thanks for you help!

Enno

PS.: still the question arise: is the size of my uInitrd the problem, or the content?
Also: where in the booting process is it used at all? as root=LABEL=rootfs (formerly root=/dev/sda1) the kernel should not need to tocuh the initrd at all.... strange.

Hi bodhi,

it works now. with the uInitrd from the debian 'stick', i can now boot my gentoo with the newer kernel!

enno@goflexnet ~ $ uname -a
Linux goflexnet 4.2.0-kirkwood-tld-1 #1 PREEMPT Mon Aug 31 23:12:00 PDT 2015 armv5tel Marvell Kirkwood (Flattened Device Tree) GNU/Linux

Thanks you so much!

Enno

PS.: No i need to learn how to recreate a working initrd and a working kernel. (any hints?)

Now I should learn how to recreate a working initrd and a working kernel. (any hints?)

Cool! Just what I expected. It's a big clue when you said it's too big.

Regenerate initrd after you add whatever needed (btrfs,...) then look at the size. Pls post that file and size here.

To regenerate initrd (this will regenerate a new initrd image base on the running kernel):

update-initramfs -u

And then to regenerate uInitrd, use the mkimage command as specified in the kernel/rootfs thread.
