It should work with older kernel, since DTS has not changed format. But if the kernel is too old, it might not have the required modules or code. Try it, 4.1 is recent.

If you look at the HP u-boot patches source code, you are going to be mad, not just annoyed :))

just flashed the uboot and envs and stuff on my thinclient n. 1.

During pre-flashing checks I saw this line

[    1.745538] m25p80 spi0.0: found sst25vf080b, expected m25p80


But then the chip was initialized correctly anyway

[    1.751336] m25p80 spi0.0: sst25vf080b (1024 Kbytes)
[    1.756396] 5 cmdlinepart partitions found on MTD device spi0.0

So I went ahead with the flashing.

Now my first box has been liberated and boots fine to Debian. Thanks bodhi. :)


During boot I see these info about GPU and sound chip (it's different from the one posted by CV):

Btw, I've seen a cpu frequency env in stock uboot. Does that mean we can bump the frequency to 1.6 Ghz like the nsa325?
Re: HP T5325 Thin Client Debian
March 12, 2016 08:52AM
the eth controller (behind the eth port) is a marvell one, this guy here Marvell-88E3016 http://www.marvell.com/transceivers/assets/Marvell-88E3016-Fast-Ethernet.pdf

will see if I can swap it with a gigabit one. hoping I can find a pin-compatible one.

It seems they are pin-upgradable to gigabit http://www.marvell.com/transceivers/assets/Marvell-Alaska-88E3015-16-18-PHY.pdf
" In addition, the 88E3016 and 88E3018 are the only single-port FE PHYs available in the industry which are pin-upgradeable to Gigabit Ethernet"

what does "pin-upgradable" mean? I hope it means they are pin-compatible with a gigabit eth controller from marvell, which would be nice.

It seems they do. http://www.marvell.com/transceivers/assets/88E1118R_Technical_Product_Brief.pdf

pins are the same. Need to check others http://www.marvell.com/transceivers/alaska-gbe/

and see if they are fully compatible with the specs of the one we have already.

so thats as far as i can take it from stock. i get the usual fw_setenv error if i try to do this from the prepped environment of a bootable usb when in bodhi's debian - i.e. cant read the information etc.

any thoughts? do we have differing equipment for differing geographic regions?

the upside is that the usb created with an embedded dtb, works fine and dandy with the correct boot_args. so while i could happily just live with this and run on the standard uboot, would be nice to migrate to the new one.

I flashed mine from debian. I kwbooted the newer uboot first (:P), but you can set the stock uboot to boot into debian too.

> i get the usual fw_setenv error if i try to do this from the prepped environment of a bootable usb when in bodhi's debian - i.e. cant read the information etc.

from inside debian you must open /etc/fw_env.config

and write
/dev/mtd2 0x00000 0x10000 0x10000

instead of the /dev/mtdX xxxxx xxxxx xxxxxx
that you find in there.

this tells fw_printenv where to find stuff.

Inside debian you should have all you need to do this.

install "mtd-utils" so you can get the flashcp utility in Debian

I would try doing this from Debian first, if it still fails, try what I say now. (at your own risk)

from the table posted

dev:    size   erasesize  name
mtd0: 00010000 00010000 "u-boot env"
mtd1: 00010000 00010000 "permanent u-boot env"
mtd2: 00010000 00010000 "HP env"
mtd3: 00080000 00010000 "u-boot"
mtd4: 00040000 00010000 "SSD firmware"

it seems you should

flashcp -v uboot.2015.10-tld-2.t5325.mtd0.kwb /dev/mtd3

as that is the mtd where uboot stays.

and the uboot envs should be flashed in what is called mtd0 in your table.

If you see the size and erasesize, also the adresses above, the actual places of all the mtd partitions are the same, but in HP stock OS they are indexed at weird places (and with less zeroes on top in the addresse, that does not matter).

HP firmware is funky, who knew? :)

Ill give it a go - if i mash it i mash it - already mashed one with a powerblip!
Re: HP T5325 Thin Client Debian

Gravelrash,

It is easier that you boot with stock u-boot, and Debian rootfs. And use the new mtdparts setting in bootargs. They are actually the same. But it is harder to flash with 1 MTD so I forced it to be like stock (5 MTDs).

Let me see... stock MTDs were like bobafett post above?

> mtd3: 00080000 00010000 "u-boot"
> mtd4: 00040000 00010000 "SSD firmware"

And, you should not flash u-boot when MTDs are different :)

Gravelrash,

If you are still trying to figure out. You can start booting again and stop at serial console. With the Debian rootfs plugged in. Let me know when you are at that point and I'll get you to Debian with the correct MTDs.

UPDATE:

I saw you are booting this box with USB Debian rootfs. So the only thing you need to do is to define mtdparts correctly in bootargs.

setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=spi0.0:512K(uboot),256K(sdd_firmware),64K(uboot_env),64K(permanent_uboot_env),64K(hp_env)'

The WOL in stock u-boot is pretty ugly :)

What we need is information about what are the values to write to the 88E1116 Ethernet PHY registers , similar to the settings in the kernel for the 88E1318S. According to the info out there, the 88E1116 does have WOL (I am puzzle, because if it is true, why nobody has done this).

Just my two cents worth

Others will have other ideas, but I believe we would be better off not reimplementing this feature.

From this discussion thread that feature has been nothing but a cause of nuisance. Maybe that's why no-one else has implemented it? It causes more issues than it solves?

The issue was because the way HP implemented it, not because the WOL implementtion in general. I won't use their approach, for sure, if I try.

However, I agreed, we don't really need this. Unless we can do it the rigth way like the current Marvell PHY driver for the 8138s, I will not bother wasting effort :)

[SOLVED]: kwbooted new uboot, then linux, then flash worked!

@Bodhi:
I just tried to flash new uboot to my second box - did'nt work, see below errors:
the NAND of my second box seems to readonly..!!!


Note: my stock /proc/mtd looked different, like that of Gravelrash, uboot was in mtd3, I think.

But I thought this wouldn't matter as
"setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=spi0.0:512K(uboot),256K(sdd_firmware),64K(uboot_env),64K(permanent_uboot_env),64K(hp_env)'"
would set the new MTD layout.

Now the good thing is nothing broke - I can still reboot my box, also cold boot - stock uboot coming up again.

See below what I did:

Thought I would post a pic of my T5325 running headless with Debian 3.17 loaded per this thread. I'm using it as a combo PBX (running IncrediblePBX for Pogoplug from here: IPBX on PP) and as a Squeezelite client (notice the Plantronics DECT base which I use for wireless music listening). I was also able to compile the 8812au driver for the shown Trendnet AC1200 wireless adapter using this source 8812au.ko for Kirkwood. Picked up the T5325 for less than the price of a movie ticket. Pretty cool :) and thanks to the contributors that made this possible.

Sorry CV, I need to add more instruction to the u-boot thread. Have not got around to do that :)

@bodhi - Im still on stock uboot as i already borked one, hopefull i can fix it and be able to kwboot when my new TTL adaptors land

@Leggo - would you be willing to share you alsa conf files and alsastate file. i would like to compare with mine and see if its actually a harware fault i have with the unit as i get no sound, but alsa reckons to be fuctioning and outputting to the correct device.

Not using built in sound device as my DECT base has USB and it shows up as an output when I change snd_usb_audio to =0 in alsa-base.conf. I couldn't get built in sound to work unfortunately.

@Leggo, thanks for the fast response. I will stick a usb sound board in for now as it sounds like your experience mirrors mine

@bodhi there appears to be from my limited research special considerations in the compilation of the Kirkwood SoC architecture for this unit in relation to sound output

Q. is it a whole bunch of work for you to mangle the sound options for this unit.

If it is then i for one dont want to take up your limited and valuable time on this unit when for approx $1 we can add sound another way.

Gravelrash,

I've included virtually all kernel options for sound. Perhaps something is still missing! It's no problem to add more. Can you find the name and model number for this sound chip?

Found it.

This could be the sound alc5623 codec patch that was missing from the kernel DTS:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-May/253014.html

UPDATE:

This patch is already in the kernel.

This could be the problem:

@bodhi you are relentless in your desire to fix problems!

I went to bed with the intention of doing more investigation this morning and you find the problem. is this something i can fix with console commands or is it one that needs to wait for your next kernel release?

BTW - im still playing with the graphics options for this unit, for some reason i cant seem to leave it alone!!.

There are apparently some options i can give to the xgifb in the inittab that modify its behaviour so im going to try that and see if i get any differing results. I do seem to be enjoying better screen response behaviours than CV reports, having said that im running at a lower resolution so that is probably the reason!

Only problem i have found that is really annoying me is that from the FULL LXDE desktop, iceweasel doesnt load, im going to look at this in a bit and i bet that i havent set the user/group permissions correctly.

This seems like it could be fixed in DTS. Will see if that was the cause. If that's true then the DTB can be updated any time.

The error (when playing with cmus):

Error: opening audio device: No such device
