Debian on HP T5325 Thin Client

One last thing......

Just ordered another two of these so we will have a few to work on until we get it right :)

Yes. I think it is best to get serial console first. Even though I'm confident that bootcmd is working as intended. We won't brick it if no default envs were changed, just carefully add new envs and it's safe to do.

Thanks so far Mr bodhi :-) *drums his fingers wondering if the boat from China has left yet*

I had serial access to mine a couple of years ago when I was playing with it. Your postings have prompted me to go digging around for my HP T5325 and see if I can update to a newer Debian release.

A quick question, does the graphics in this thing work outside of the original firmware? I somehow doubt that a 7yo closed-source driver will cut it, but it would be cool to get a kirkwood device with a GPU.

Also, does it have a Sata port? on wikidevi they say "Board is tracked for a SATA interface.", does that mean it has traces for a Sata port mod?

Can you post some pics of the naked board?

standard debian on the HPT5325 - however it doesnt give a newer uboot ---CORRECT ME IF I AM WRONG

@bobbafethotmail
there is a wheezy/jessie package to install the necessary graphics driver, as to "cut it" that all depends on your use case - mine will be console access only. Board images are available on spritemods page, have a look at some of these

https://www.google.com/search?sclient=tablet-gws&biw=1280&bih=619&tbm=isch&sa=1&q=HP+T5325&oq=HP+T5325&gs_l=tablet-gws.3..0j0i8i30j0i24.25330.27011.0.27596.14.9.0.0.0.0.551.1250.2-3j5-1.4.0....0...1c.1.64.tablet-gws..12.2.773.55Bsglw2v4M

Oh, cool you're right. https://cgit.freedesktop.org/xorg/driver/xf86-video-xgi/

There is indeed an open driver for it, and it is still alive, it even got EXA 2D acceleration before XGI died (XAA has been removed in modern kernels) http://www.phoronix.com/scan.php?page=news_item&px=NzkyNA

Of course I only expect this thing to do 2D at a decent fullhd resolution, but having a fully opensource system with opensource driver on ARM is a pretty damn rare sight nowadays.

Ok, I'mma grabbing a couple off ebay for cheep (20 euros or so total, if none comes annoy me) to see how horribly slow runs a linux desktop on a poor Kirkwood. :)

Hi all,

I was following this thread very interestedly yet quietly just until now .....
as now I have an serial connection to my t5325!

(my UBOOT log see below)

@Bodhi:
Soso - as long as Gravelrash is not here or maybe has not yet got yet this JST cable,
I'm ready to step in and try anything you suggest, Bodhi!

Waiting excitedly,

Cheers,
Christian

cv,

Do you have rootfs 3.18.5 running on another Kirkwood box?

Hi Bodhi,

cool you are online!
I have a Dockstar as my home server with this kernel:
$ uname -a
Linux debiandock 3.2.0-4-kirkwood #1 Debian 3.2.68-1+deb7u6 armv5tel GNU/Linux


But I have another currently not used rockstar I could install it on,

Shall I?

PS: I will register to the forum.

Ah nice. I'm waiting for the cables (dunno about Gravelrash).

Can you test if this box can UART boot? (see here) http://forum.doozan.com/read.php?3,7852,7852

It's a pretty important feature, if it can UART-boot it's easy to unbrick, testing will be faster and safer.

EDIT: removing link as bodhi provided a better one



Edited 1 time(s). Last edit at 02/25/2016 04:04PM by bobafetthotmail.

cv,

Yes try UART booting, but don't use the nsa325 u-boot.

Use the 2015.10 sheevaplug u-boot:
http://forum.doozan.com/read.php?3,12381

The kwboot binary link is in the above thread.

The serial console on the Dockstar, connect to the T5325 and

./kwboot  -t -B 115200 /dev/ttyUSB0 -b uboot.2015.10-tld-1.sheevaplug.mtd0.kwb -p

@cv,

Booting Debian with stock u-boot.

Download the rootfs tarball and create it on a USB. See http://forum.doozan.com/read.php?2,12096. Follow the instruction very closely (being root user, rootfs label,...).

Quote

Updated 24 Feb 2015:

This rootfs is the first Debian jessie rootfs in my Kirkwood kernel/rootfs release series, and to keep in sync with kernel Linux-3.18.5-kirkwood-tld-1.

You need to do the embedded DTB in step 4

Quote

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier).

Note that this instruction use kernel 4.4, replace it with 3.18.5 if booting the new 3.18.5 rootfs.

Generate the uImage with DTB embedded inside:

cd /media/sdb1/boot
cp -a zImage-4.4.0-kirkwood-tld-1  zImage.fdt
cat dts/kirkwood-t5325.dtb  >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.4.0-kirkwood-tld-1 -d zImage.fdt  uImage
sync

Plug this USB rootfs in the HP T5325. Power up, interrupt serial console and:

setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10'
setenv load_usb 'usb start; ext2load usb 0:1 0x800000 /boot/uImage; ext2load usb 0:1  0x1100000 /boot/uInitrd'
setenv bootcmd_usb 'setenv bootargs $(bootargs_usb); run load_usb; bootm 0x800000 0x1100000
setenv bootcmd 'run bootcmd_usb; run thinpro'

@bodhi: why fatload in the envs? that uboot has ext2load too as said here https://pointless.net/blog/2014/04/17/debian-wheezy-hp-t5352-thin-client/
I'm half sure that Debian cannot run from fat filesystem (although you can make a fat partition for boot folder only, but in this case it's pointless).

@cv: can you post the result of "printenv" in uboot serial console?

That was the stock envs. You're right in that it shoud be ext2load command, I forgot :)

Hi Bodhi,
I have problems with my Prolific USB to serial Adapter.
(Works totally unreliable on my MacBook, and only a little better with my Linux Laptop,
most of the time i get to the uboot prompt, but soon loose connection, hang ups, tty.usbserial disappears, have to un- and replug it.)
I don't have another working PC ATM with a real serial port, i could setup one but i do also not have a level shifter... will get one.

So now I'm setting up my unused Dockstar to be the serial netboot provider for the t5325.

But it will take some time, i already built a 3 wire serial crossover cable: correct me if i am wrong, i need tx<->rx, right?
Plus i did not manage to open my Dockstar - the plastic top seems to have glued or whatever to the bottom - it has gotten sticky and yellow!
(i know how to open it, had it open when i got it some years ago.)
It sat in its original packing in my basement, so no sun, heat or anything. why???
I need to dremel or crack it open.

so sorry, no progress yet, but i will get on eventually!
thanks,
CV

I don't think that making a UART crossover is a good idea. I'd just buy another USB-UART dongle.

I'm using a bunch of these adapters lately and they are pretty good (and cheep)
http://www.ebay.co.uk/itm/221928826670?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

the chip is CP2102 (yours is a different chip and a different brand) and works fine in windows (need drivers, easy to find on google) and linux (no drivers needed).

Hi,
got my serial to work, it was a badly crimped pin...

I created the roofts following your instruction "http://forum.doozan.com/read.php?2,12096. ".
I used a 4GB USB Stick.

Partial success, it boots your kernel!:

PS: fascinating to watch some reboot cycles - kernel shutting down - uboot coming up - kernel booting...
Booting stable and fast!

Also cold cycling works (power plug on/off).

But there is this error:

This is expected. The basic rootfs does not have the right address for the stock u-boot envs. Let me take a look.

Don't do saveenv yet.

Boot with serial console, interrupt it, and get the stock envs listing and the commands available:

printenv
help

And then setenv and boot

setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10'
setenv load_usb 'usb start; ext2load usb 0:1 0x800000 /boot/uImage; ext2load usb 0:1  0x1100000 /boot/uInitrd'
setenv bootcmd_usb 'setenv bootargs $(bootargs_usb); run load_usb; bootm 0x800000 0x1100000
setenv bootcmd 'run bootcmd_usb; run thinpro'
boot

In Debian

cat /etc/fw_env.config
cat /proc/mtd
ls -l /dev/mtd*

Sorry, to late, I already had done it, you see it in my printenv.
But I can provide it from another t5325 on monday, "unspoiled".

I will do some checks with the kernel, setup as a fileserver (smb, nfs, iscsitarget, tftp, etc) and report.

But as I said, it looks pretty stable for now - i did multiple reboot cylces, cold/warm,
did apt-get update/upgrade/autoremove/install...
Will check X as well later on.

Thanks for your support and great work!

No need to. Gravelrash already supplied this up thread. But it would be good if you post your curren u-boot envs. This is for confirmation and for others to use. And then I'll add this to kernel support list.

For new u-boot, I'm looking for confirmation that kwboot can be used to boot UART, and information in Debian about the MTD partittions.

#
# HP T5325 Thin Client
/dev/mtd0		0xc0000 	0x10000       0x10000

And do
