Followup:  Yeah, it looks like it just doesn't know which format of 
zImage to produce for linkstation.

I'm not sure what image should be used by default.  I guess it depends 
on the bootloader.  Maybe default to uImage, as uBoot seems to be fairly 
common on these devices?

Yes, uImage is the format used on linkstation. Is there a way to cleanly 
specify this in the kernel sources apart from a comment in Kconfig?

Yep.  Kconfig just needs to select DEFAULT_UIMAGE, and then the system 
tries to build a uImage.

Once I tracked down and installed a "mkimage" command (dependency needed 
by the WRAP line), my "make zImage" succeeded.  So, I hope you guys 
apply this.

Thanks for the patch. Are you actually going to test this kernel on a real 
hardware or just testing builds? If it is going to be a real life test, 
I'd be interested to know what exactly hardware, U-boot version, dts, and 
what results.

BTW, ack-ing your patch would be a bit easier if you sent it inline.

Yes, I do very much intend to test it on real hardware.  I have a couple 
of Kurobox HGs which desperately need a 21st century kernel.  I still 
need to install U-boot on it, but first I'm just going to test the 
vmlinux with the loader.o kernel module.  (And my rs232 voltage 
converters haven't gotten here yet, so I'm being a little conservative 
about all of this.)

Yeah, thunderbird sucks for this stuff.  Keep nagging me and I'll set up 
mutt again. :)  Thanks!

Ah, what a pity:-) I mean, it is good, but it's exactly the same hardware 
I developed this port for and tested on. So, it should be easy. If you 
have any problems with your setup, look in linkstation / kurobox mailing 
list archives, I posted some instructions there for setting up a suitable 
u-boot version. Or just ask me. Or I could even just send you binaries to 
start with. Do you have JTag?...

No, I haven't made any hardware mods yet.

Thanks for the offer.  Kernel binaries might actually help, just to make 
sure the hardware and bootloader are working properly.

The instructions on 
http://www.linuxnotincluded.pwp.blueyonder.co.uk/linkstation/u-bootinstall.html 
were a little broken in a few places, but still very helpful.  I've got 
U-boot 1.1.4 up and running.  It's just booting the old 2.4.17_mvl21 
from flash right now... 2.6.20-rc2 fails to boot.

I have ordered some serial port voltage converters, which I hope to use 
to get some diagnostics from the 2.6.20-rc2 kernel.  I don't hear any 
disk activity, and I wasn't able to get netconsole working, so I think 
it is dying fairly early in the boot process.  (At least, before PCI and 
network are up.)

I asked about JTag because the U-boot you'll have to flash to boot an 
arch/powerpc based kernel has only been so far tested on one (mine) 
KuroboxHG. It is (hopefully) the same hardware as yours, but you never 
know...

> Thanks for the offer.  Kernel binaries might actually help, just to make

Yes, I can send you the kernel, but I think, it is the u-boot that's most 
critical and difficult to build, since what I am running is some checkout 
from a git tree with a modified kurobox patch applied, and you might want 
to start with a precompiled u-boot. The fdt blob and the kernel are no 
longer as critical and much easier to build - just kernel.org kernel with 
the default defconfig, but I can send you those too, if you want.

No, those won't help you directly. That U-boot will not be able to boot an 
arch/powerpc based kernel. You have to know: there are currently 2 ways to 
boot a 2.6 kernel on a linkstation/kurobox. 1: which most (everybody 
except me) use - U-boot like what you've built or loader.o + an arch/ppc 
based kernel, 2: U-boot based on a version, capable of booting kernels 
with an fdt blob (i.e., per "mboot <kernel-addr> [<initrd-addr>] 
<fdt-addr>"). If you want the vanilla kernel you need the second method, 
hence a newer version of U-boot.

Look here: http://www.kurobox.com/revolution/downloads/contest/patchREADME 
for a somewhat rough README and here 
http://www.kurobox.com/revolution/downloads/contest/patches.zip are the 
patches (sorry about the zip - that was revolution's format of choice...)

But even if I send you an image of U-boot that works for me, I'd have to 
warn you if you don't have the jtag port enabled / are not ready to use it 
to recover a possible bricked kurobox. You've been warned...

Thanks a bunch.  A RAM build of uBoot boots the old kernel fine, so I'll 
replace my older uBoot with it.  The only trouble I had was stripping 
carriage returns out of the patches in that zipfile; after that, 
everything went pretty smoothly.

I noticed uBoot is looking for a *.dtb file, as well as the kernel 
image.  The patchREADME refers to a "dtc" tool, but the URL it gives 
(http://ozlabs.org/~dgibson/dtc/dtc.tar.gz) does not exist.  So I 
googled and found git://ozlabs.org/srv/projects/dtc/dtc.git, and tried 
to compile kuroboxHG.dts, with the command line specified within that file:

$ dtc -f -I dts -O dtb -o kuroboxHG.dtb -V 16 kuroboxHG.dts
DTC: dts->dtb  on file "kuroboxHG.dts"
ERROR: Missing /chosen node
Input tree has errors

So, uh... is the *.dts file in 2.6.20-rc2 bad, or am I compiling it 
wrongly?  (And is this normally done by hand, or as part of the kernel 
build process?)

Thanks,

mark

You need to pass the -f option to dtc.  Hopefully, dtc will be fixed to 
not complain about this at some point.

the warning is fine. the "chosen" node is filled out by u-boot(instead 
of the generated dtb file) for the time being. you can do a quick 
reverse dtc to check your dtb binary:

$dtc -f -I dtb -O dts -V 0x10 kuroboxHG.dtb > kuroboxHG.dts.check

Wow! You are the first who followed my instructions and to that

Urrrggggh, those carriage returns - I don't have any *DOS* here AT ALL...

That's ok. You DO have the "-f" which does produce an output. The error is 
because the "chosen" is not there, but this is how we need it for U-boot. 

It's done by hand.

So, you've done everything right! Congrats:-)

Great.  Any chance you can send me your kernel config?  My IDE support 
isn't working, and I'd like to figure out why.

Usually I get:

NET: Registered protocol family 1

But once, just once, when booting from a RAM build of uBoot, I got:

Thank goodness for netconsole.  I think it's especially interesting that 
it thinks IDE0 is on irq 20, when the old 2.4.17 kernel says:

hda: WDC WD3200JB-00KFA0, ATA DISK drive
ide0 at 0xbffef8-0xbffeff,0xbffef6 on irq 17

Hmm... 2.6.20, irq20.  2.4.17, irq17.  Interesting coincidence.  Anyway, 
it is either detected wrongly, or specified wrongly.  But your kernel 
config would help me to make sure I'm at least using the right driver. :)

Think it might be something I could work around by fiddling with the 
interrupt-map in that kuroboxHG.dts file?  The IDE IRQ seems wrong, even 
if the network port obviously works (though I bet netconsole transmits 
even if the IRQ is wrong).  Are they allocated dynamically on this 
architecture, or should I expect the IRQ numbers to be the same between 
2.4 and 2.6?

Thanks,

Mark

My config is in the kernel - arch/powerpc/configs/linkstation_defconfig.
And I don't use IDE, I use PATA, and it works good, I also had problems 
with IDE, although, not as bad as you describe. Also, you, certainly, need 
root=/dev/sda1, not hda1, change it in your U-boot environment. As for 
interrupt numbers - they are correct, and they are (pretty) arbitrary, 
allocated dynamically. I have:

Note that it's already pretty far out of date, if you do a "make

Hmm.  I have both PATA and IDE enabled... that's probably why its 
breaking so badly.  Thanks for the tip, I'll give it a try tomorrow morning.

Thanks, disabling IDE worked.  It took a couple tries due to a Makefile

figure out why my Gentoo userspace won't boot, which I think is beyond

One issue I ran into is that "make zImage" does not rebuild an existing 
image, but "make uImage" does... I think the Makefile is missing a 
dependency.  I'll send a patch if I debug this further.  I know the 
"zImage" rule is just there for convenience, but apparently zImage is a 
deeply ingrained habit for me.

Well, you're welcome to (subscribe and) continue discussing any kurobox / 
linkstation non kernel-related issues on the respective yahoo-groups list. 
No, I am not specifically happy about the choice of the list hosting, but 
- it wasn't mine. As a guess - mostly you have to modify /etc/fstab, 
sometimes S.M.A.R.T. related configuration, usually not much more than 
that. But I don't use gentoo - there are guys there that do, they'll be 
able to help, if they read those lists... Most discussions take place on 
online forums, which I like even less. (Sorry for the OT.)

Thanks

Re: Linux 2.6.20-rc2: forgot how to make a zImage on powerpc?

Hmm.  I'm trying to build 2.6.20-rc2 on a little powerpc box with 
arch/powerpc/configs/linkstation_defconfig, and I get:

ln: accessing `arch/powerpc/boot/zImage': No such file or directory
make[1]: *** [arch/powerpc/boot/zImage] Error 1
make: *** [zImage] Error 2

So, uh, are we forgetting to go into the right subdirectory to make the 
actual zImage, or what?  If I'm just doing something wrong, I'd love to 
know what it is.

I'll follow up here on lkml if I diagnose this further.  Thanks,

Mark
