Debian on HP T5325 Thin Client

syong,

The fact that it is playing the file is encouraging. I did not even got that far before.

This DTB version should fix it. However, I can't still hear anything from the headphone (but my sound settings might be wrong). So please try.

WORKING! An epic progess! Thank you bodhi! What is the magic? Did you change something in kirkwboot.dtsi?

The puzzle of sound on t5325 is solved! Let me playback what I did:

1. Use bodhi's latest DTB and append to the kernel as if still using stock uBoot.

2. Change /usr/share/alsa/alsa.conf as following:

#pcm.front cards.pcm.front
pcm.front cards.pcm.default

3. Turn the knobs using alsamixer

Switches(m key to toggle mute):

Speaker Mix DAC2SPK
HP Mix DAC2HP
Left Headphone Mux [HP Left Mix]
Right Headphone Mux [HP Right Mix]

Sliders:(up/down key)

Headphone
Speaker
PCM

4. Enjoy the multimedia guinea plug using mpg321.

BTW, I have not tried recording yet. The slide(Mic 1/2 Boost) seems does not work.

-syong

Cool :)

Just what I had suspected, eventhough I used alsamixer to adjust my sound levels like you did, something is still not right in my plug. That's made testing a little difficult!

The fix: the audio controller was missing a cell:

Note that changing this does not effect other Kirkwood boxes, only boxes that have audio-controller@a0000 node in their DTS.

Thanks for testing syong.

!! WOW !! - You guys are amazing! I am going to go in the garage more often, whenever i do you fix something :))

So this link will sort out the onboard sound and allow it to be used without the need for a usb dongle? If thats the case, then i will update the HOWTO to include sound as well. all thats left now is the graphics adaptor

http://forum.doozan.com/file.php?2,file=882,filename=kirkwood-t5325.dtb

Gravelrash,

Yes, that latest DTB in:
http://forum.doozan.com/read.php?2,25473,27556#msg-27556

BTW, looks like I might want to release a new kernel tld-2 with all these small changes lately.

:)) similar thing I often said to myself (when figuring out a solution in the shower).

Are we missing something with graphics adaptor?

Unknown, someone needs to compile/configure a working driver first. I will give some tries later this week.

I think it should not need dtb changes tho, but you never really know until you try.

Unknown meaning it never works right because we need to port the correct driver?

It means we don't know if you need to hack the dtb some more, until we have a working 2D driver we can't really operate the GPU (we are at frambefuffer only, this is 2D-capable hardware), nor see if it gives errors about lack of dtb settings.

Ah, I remember now. Thanks.

@bobafetthotmail

Have you had any joy building the driver? all my efforts have resulted in "snarks" about incorrect/invalid macros settings. which i cant seem to get around.

I posted a question for all people interested in using the GPU on this box, and for those that know something about kernel, pci IDs, and libpciaccess library.
please head here in the thread for graphics for this box http://forum.doozan.com/read.php?9,26555,page=3

Bodhi,

Sorry for the late reply. As you can see I am a slow learner.:)

In this case, it is better not touching kirkwood.dtsi and only patching kirkwood-t5325.dts as follows:

                simple-audio-card,dai-link {
                        format = "i2s";
                        codec {
                                sound-dai = <&alc5621>;
                        };
                        cpu {
                                sound-dai = <&audio0 0>;
                        };
                };
        };
};
&audio0 {
        #sound-dai-cells = <1>;
        status = "ok";
};

syong,

Very good observation! I'll do that in the final version for release. Much cleaner.

Hello men. This great topic i found few months ago, clean dust from mine brand new but forgotten T5325 and follow up from it's original HP system. You are doing great job hacking this device.

Due lack of time and some wires only now I manage to setup this box with external sata harddrive:

HP>> ide reset

Just try to boot it with bodhi's kernel-4.5.0 with embedded t5325 dtb and rootfs and found that in this kernel sata controller is not initialized during bootup so it can not mount rootfs form /dev/sdb4 in my case.
I'm using original uboot and this bootargs:

fw_setenv bootargs_ide 'console=tty0 console=ttyS0,115200 root=LABEL=rootfs rootdelay=10'
fw_setenv load_ide 'ide reset; ext2load ide 1:4 0x200000 /boot/uImage-4.5.0'
fw_setenv bootcmd_ide 'setenv bootargs $(bootargs_ide); run load_ide; bootm 0x200000'
fw_setenv bootcmd 'run bootcmd_ide; run thinpro'

Am I miss something? Is there are any circumvent of this "feature"?

PS. If anyone interested howto setup second SATA port I can describe it here in this topic.

xssa,

IDE rootfs should work. Can you post your serial console boot log?

Or you can install new u-boot: http://forum.doozan.com/read.php?3,26562. Try kwboot first and see if it all works for you.

Please, pay attention to the mtdparts in u-boot installation. If you have changed it to boot latest rootfs, then it is easy. If not, slight adjustment is needed in the instruction (I need to revise it to add from-stock-OS installation).

Make sure your rootfs partition is labeled:

tune2fs -L rootfs /dev/sda4

Finaly got it!
Booting kernel-4.4.0 with embedded latest kirkwood-t5325.dtb and its uInitrd in /boot and viola!!! rootfs on /dev/sdb4 mounted as expected with label=rootfs.

Next steps to get running kernel-4.5.0 with fbcons enabled:

root@debian:~# apt-get update
...
root@debian:~# echo "xgifb" >> /etc/initramfs-tools/modules
root@debian:~# echo "fbcon" >> /etc/initramfs-tools/modules
root@debian:~# dpkg -i /boot/45/linux-image-4.5.0-kirkwood-tld-1_1.0_armel.deb
...
root@debian:~# cd /boot
root@debian:/boot# mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-4.5.0-kirkwood-tld-1 -d initrd.img-4.5.0-kirkwood-tld-1 uInitrd-4.5.0
...

Then reboot to original thinpro linux and setup new uboot environment:

HP>> run thinpro
...
fw_setenv load_ide 'ide reset; ext2load ide 1:4 0x800000 /boot/uImage-4.5.0; ext2load ide 1:4 0x1100000 /boot/uInitrd-4.5.0'
fw_setenv bootcmd_ide 'setenv bootargs $(bootargs_ide); run load_ide; bootm 0x800000 0x1100000'
fw_setenv bootargs_ide 'console=tty0 console=ttyS0,115200 root=LABEL=rootfs'

rootdelay=10 is redundant for SATA :)

And, most important conclusion:

sata_mv                25104  2
libata                164641  1 sata_mv

are not included in kernel but loaded from initramfs.

Glad it works for you :)

FYI, also for the benefit of others who came from Arch or OpenWrt or a different distro. If you've followed the instructions in the Debian kernel/rootfs thread closely, then it just works! there is really no need to do any thing extra. IOW, if you boot with the rootfs label, then initramfs is required. And sata_mv is always running that way, so initramfs is doubly important. For Debian users, it's kind of given, but for Arch or OpenWrt users, this might be new.

yes please! A writeup with images would be really beneficial to everyone

I have done the SATA mod, very ghetto style... SATA cable cut, split and directly soldered to the board. Mechanical stability not great,
I will search for a machting SATA connector (footprint B I think).

My method to add SATA harddrive to thin client HP T5325 is a slightly modified method described on here.
Changes are focused on to preserving case modification and it's servicability.
For modifications we need:
- 4 pcs. AC coupling 10nF capacitors for SATA datalines in 0402 SMD package. I use capacitors with corresponding dimentions and similar purpose found near SATA connectors on the broken old mATX motherboard.
- HP DV7-6000 SATA cable. Was bought on Aliexpress. On Ebay there also some.
- 2,5" HDD and 2 screws.
- Hot air rework station and/or soldering iron with skills :)
- Micro JST 1.25 4-Pin Female Connector plug with Wires. Was cut from CPU fan found on old broken ASUS notebook and used with TTL to RS232 adapter for testing and debugging proposes.

1) First we need to disassemble t5325 and to solder 4 capacitors C80-C83 near SATA pads on the upside and downside of the board.
2) Disassemble motherboard connector on the HP DV7 SATA cable, unsolder wires from connector pads from left to right and solder them to correspondong pads on the t5325 motherboard in the row. Look to the pictures in attachment and use this pinount from left to right:
p12,p11,p10,p9,p8,p7...s6,s5,s4,s3,s2
gnd,gnd,gnd,5V,5V,5V...Rx+,Rx-,gnd,Tx-,Tx+
Be careful and not mix them.
3) There is no place for 2,5" harddrive inside the case so we need to push cable somewere outside:
Fix SATA cable to CPU cooler spring, push it's HDD SATA connector through the hole for the LAN connector on casing backside and assemble t5325 motherboard into casing.
4) Screw the 2,5 harddrive to the top cover with 2 screws. Assemble the case completly and connect harddrive to our cable.
5) Boot up our modified thin client. Recently connected hard drive will be seen in u-boot and original thinpro linux. All further partitioning, software setup and u-boot environment variables modification can be done in original thinpro linux. Just open Xconsole or connect to it by ssh. But you will be blind if something goes wrong during booting. In this cases MicroJST serial TTL to RS232 cable is useful.

There are some more pictures but can't attach it here.
