Re: Hantek - Tekway - DSO hack - get 200MHz bw for free

I've been following the thread, I've got a really early DSO1102B handheld scope with firmware 2.01.1

None of the hacked firmware I can find will work with it! It all saysx for 2.5-2.6 etc.
I got it from China when they were first released. Can anybody run me through how to hack my device to 200mhz or point me to a link?

Even Hantek doesn't have firmware on their page so I can't update the device.

i should probably start separate thread about the new Hantek handhelds (DSO1xxxB/BV/S)
EDIT: i updated now the first post in this thread, so ppl who have such handhelds will find immediately
some informatios before they spend like you a day or two to recognize that handheld and bench are
in principle similar but different enought to make the hacks more complex (from model point of view)

Anyway, they based on the bench models sp let's short introduce them :

Available models :
DSO1062B / BV / S
DSO1102B / BV / S
DSO1202B / BV / S

B - are standard models, BV have SD card and video player, S are with isolated channels.
What i got until now (and of course hacked, disassembled, documented, even draw part of schematics ...) are
the B and BV models.

The hardware is very similar to bench models, however they have of course some additions like DMM (FS9922-DMM4 chip),
power management (MSP430F2011), different i/o header, additional unpopulated header for BT2UART modules
(CSR Bluetooth Chip Solution , ebay for Bluetooth UART - they can be used as third uart over BT, i do have
these modules but didn't found time to test it ...)

They do have already LAN - but it seems to be option and not everbody is selling them with LAN,
in case you bought without LAN it is easy to populate the missing parts - all you need
is DM9000EP chip + magnetics and RJ45 jack - and small change in EEPROM licensing (see below).
You don't need 25MHz quarz for DM9000EP as on handheld LAN chip is clocked by FPGA
(on bench hw1007 seems to be not that case)


Display (AT056TN53 V. 1) have 640x480 resolution, 15 x 8.5DIV, menu popus on the bottom, this is te only resolution
(not like on bench model where 20 or 16div possible).

FPGA is the same as in bench DSO, but the FPGA design is different and already much better - these handhelds
have less jitter than the bench models, i like them already.

All current available models have max 1Mpoint memory, however the firmware support already TODAY 2Mpoint,
all you need is new SRAM chip (IS61LP51236A-200TQLI works in my handheld just perfect) and of course a small hack
which is changing EEPROM content (all licensing informations are stored there, even on newest bench models
even if not yet fully used to identify - but don't worry - easy to change/hack).

Of course 2Mpoint will only work when the CPLD (which is address counter for SRAM) supports this too
- luckily this is already implemented :) So in principle when you buy/replace SRAM and hack the licensing
(i can tell you via PM how to do this) you will get an BMV handheld - which even didn't exist today
officialy (but it does in the Hantek catalog from HK Fair, so they will come later 2012 on market)
The SRAM is not cheap and you need to be careful during unsoldering the old SRAM (don't use hot air,
FPGA is ot far enough, you might blow away some FPGA balls ... i used ChipQuick successfuly to remove old SRAM)

The linux is 2.6.30.4 kernel based, like on the (still not yet officially) released BM/BMV bench models.
The dso.exe, so the actuall application is NOT YET universal, i can see common things in bench and handheld model firmwares,
but up to now (and this will stay like that probably forever or at least long time) handheld firmware and bench firmware
are DIFFERENT !!!

So don't even try to run bench firmwares on handheld (or vice versa) - the resolution is different, the keyboard mapping
is different and of course kernel / root fs is different today (handheld 2.6.30.4, bench 2.6.13)

Luckily you can't destroy by downloading/updating with official firmware because the gpg password has been changed,
it is not anymore 0571tekway, not on handheld it is 111111

There is firmware available (2.01.1_20111213) on the website, http://www.hantek.com/Product/DSO1000B/Firmware.rar
however befor you update tell me what version is on your handheld ? (sw version field in about).

The backup tool posted in this thread will not work on handheld because of different password,
you might create your own or wait until i or someone else did it
(i can do it when you promise to make a backup of your handheld and share this backup with me)

For now, as you probably wish to use the 200MHz bw i can tell you that the hack itsel remains the same,
you have to open the unit, connect over uart (see attached picture for pinout) and do the hack manually

rename dst1102b file ( mv /dst1102b /dst1202b

edit logotype file (with vi /logotype ) and change dst1102b to dst1202b
edit logotype.dis file (with vi /logotype.dis ) and change Hantek_DSO1102B to Hantek_DSO1202B
edit tmpdst file (with vi /tmpdst ) and change /dst1102b to /dst1202b


The logo itself, hehe, it is now not anymore a bitmap file loaded via device driver (and based on model name in logotype.dis),
now it is hard compiled in the /disp file, so even when you hack the device to 200MHz during boot the logo
will be still telling DSO1102B (which seems to be a protection again chinese shops who still selling hacked 60MHz bench models
as 200MHz models - of course with new front sticker). It is not a real protection, but yeah, for sure it sucks to see different
model name but if you don't like it you can edit the /disp file with hexeditor and repalce the DST1102B picture by DST1202B.
Well, or wait - maybe some day someone will buy such handheld and sahre with us the /dsip executable, but
that's only logo - it have NO influence on any bw/settings, so who cares.

What else, yeah, the official export models have proper fuses (KTK-1, KTK-10) and better input protection
for DMM, models available via chinese sellers have cheap fuses only. If you don't care about CATIII you can
work with the cheap fuses too (in case you got such model).

What else .. hmm, a yeah, these BV model have the audio codec populated (UDA1341TS), small mono amplifier (TPA4861)
and ugly  headspeaker - if you don't need audio in video player you don't need them to be soldered.
However to enable the video function you need to hack video licensing (again in EEPROM). The SD card
is somehow part of the BV models too, all you need is micro SD holder, SD card and again licesning enabled in EEPROM.
SD will ge mounted into /mnt/sd, usb flash drive into /mnt/udisk (not just in /mnt like on bench models, which is again
a small tap whey you try to use e.g. backup tool from this thread)

Anything else , hmm, right - the UART port can be connected to unused LAN jack pins over optocouplers -they need
of course to be populated. Haven't tested how good this works, but from the PCB routing seems to be everything ok.


So i hope that was a nice short introduction about what already possible/known about these handhelds :)
I'm sure this time Hantek will start hunting me, but hey, it's not my fault that these scopes/handhelds are so
user/hack friendly (and well, very good gears too).


Edit: attached picture of licensing features enabled on my DSO - 2Mpoint, LAN, SD, Video - you can find
this menu point in utility, 5/5 page, more... button, sys features button.

Hello,

I have a problem with my Tekway DST1062B - the scope hangs with white screen after running for about 30 seconds to 30 minutes. I have tried upgrading the factory firmware to version 2.06.3 (111202.0) - no change. I have not tried to hack the scope yet.

Hardware version shown is 10050x555583e8, serial number T 1G/005 003613.

Do you have any advice? Thank you!

Ivo

HW fail can not repair with upgrading FW!

Nearly sure it is main board fail. I have seen this situation "more than one time".
Take contact seller or if seller do not care then to Hantek service for repair or spare part main board. (It must be free or nearly free to you if warranty is still valid)
EU: Owon oscilloscopes and in Finland also  some Siglent selected equipments. All with our  lab deep Q.C. in Finland.  Surplus test equipments. Repair service. 40 year experience about electric and electronic repair, service and design. Local Owon SDS-Series  repair service for our customers.

Backup tool for Hantek Handhelds : DSO1062B/BV/S, DSO1102B/BV/S, DSO1202B/BV/S

- download the attached file and unzip the dso1kb_backup_tool.up (MD5 41873654111d34ef71c6f7ecc10a9951)
- copy the dso1kb_backup_tool.up to flash drive, ensure nothing else on that drive
- insert flash drive into Handheld usb port
- run firmware update (Utility, Page 1/5, Uptdate and F4 to confirm)

Handheld will reboot automatically after "firmware update" is ready (in this case backup of firmware).
Now you can remove flash drive and save the content in a secure location.

This white screen can come from 3.3V regulator that should perform a voltage between 3.2~3.4. If this voltage is lower than 3.2V,then it may produce this white screen.
Elec3i has met this kind of behaviour already and has changed the power unit in some DSO to avoid this, It is why we test our devices one by one with at least 72 hours burn-in period... ;)

Hello pgup62,
thank you very much! It seems that some tuning of the 3.3 V regulator circuit helped. (I hope :) )

Pascal,

as already asked here :

https://www.eevblog.com/forum/product-reviews-photos-and-discussion/hantek-dso1202b-or-owon-sds7102/msg87209/#msg87209

- are these Handhelds with or without LAN?
- are these Handhelds true CATIII certified (KTK-1, KTK10 fuses + protection or simple 250V fuses?)

Hi,

I recently bought a DST1102B for my hackerspace and few ppl have used recently. After their use (sampling/recording/etc) the oscilloscope is freezing, randomly. Really randomly. On my own opinion, I think there is some broken samples still remaining on the file system, cause when I do a "df" on the debug console, I got :
Filesystem      1K-blocks      Used      Available       Use        Mount
/dev/root        63152          63152          0             100%        /
[...]

I would like to know :
- Where are recorded the samples before recording them on an usb key ?
- Is it normal to have the root filesystem used at 100% ?
- Have you ever met this problem before ?

Thanks a lot, waiting for your answer :)

... Later, I will put the hack on the track. Later :)

heh, you should probably kill some ppl for that

Filesystem      1K-blocks      Used      Available       Use        Mount
/dev/root        63152          63152          0             100%        /

I would like to know :
- Where are recorded the samples before recording them on an usb key ?
- Is it normal to have the root filesystem used at 100% ?
- Have you ever met this problem before ?

- tmp fs
- no, it should be never like that, typical used space is about 40-50%
- no never ever

You should check root fs for strane files, look in /param/ (and subdirs), /mnt (and subdirs if any) and / itself,
if you don't know if specific files are necessary or not just ask here, i will answer then.

Hi
I just receive my DSO5102B
First I change it into DSO5202B and everything works great. Thanks for great job with reverese engineering.
Now I have a HW 10070 of PCB and there is a space on it for RJ45 for LAN and I wonder if it is possible to just add this connector and enable this option in firmware???

Hi,

Unfortunately I had the same problem as djeans, my scope locked up at the weekend. Totally unresponsive, powers up ok but just freezes after the hantek logo with the normal scope display, both traces on, run button lit up etc.
I tried the reset tool over USB but that did not work.
I am in the process of making a lead up for the uart, but which files do I delete and can they be backed up first ?
From a earlier post 
remove the /param/sav/run* and /param/sav/run*

arent these two the same ? Or am I missing something.

Paul.

it seems to be issue with the latest models (what is your version in system info->hw? 555583e8 or 83e9 ?)


I tried the reset tool over USB but that did not work.

yeah, it works as long scope is responding to anything.
If (due broken setting file - the one in /param/sav ...) the dso.exe is unable to startup properly the USB reset tools is not working.

From a earlier post 
remove the /param/sav/run* and /param/sav/run*
arent these two the same ? Or am I missing something.

that was typo, it should be
- remove the /param/sav/run* and /param/sav/udisk/run*

No, this behaviour can also be found on oldest versions (0x10050 555583e8) !

sure, even the hw0 will sometimes write worng values into setting file, especialy when you power off
DSO while it was wrinting this file.

But now it seems to be just too much, i know already 6 ppl having exact same issue and  all 6 have latest hw version
with 83e9 design - within few days twice to number of issues from last 2 yrs ...

What additional unfortunate is the fact that the "default setup" button is not doing anything, before a
DSO with broken setup was always booting and it was enough to push once default setup button .. now ppl
have to disasemble scopes and delete manualy the file ...

Well a bit tricky: hw or sw or both ?
last 25 devices (0x10070 555583e9) show normal behaviour after booting-up and 72 hours continuous operation. we have 2 old versions (10050 555583e8) that have this after boot-up freeze behaviour, one just after HMI appears (menus and waveforms), another within 20seconds-1hour after boot.
It seems that this can be a hw attitude (power voltage fall for instance from FPGA  or CPU sides).

I have had the scope for a few months, and it has locked up a few times but always reset itself when I switched it off and on again. It was quite bad with the original firmware 110531.1 but after I upgraded to 110909 it was very stable.
However I upgraded it to 111226 two weeks ago and it started locking up again ! this time I had just changed the memory depth and did not notice that had locked up until after 30 seconds or more, and it does not matter how many times its switched off and on it remains totally locked up.

The hardware version is 83e8

BTW I didnt notice that the header is a 2mm pitch until I tried to plug in my 0.1” lead, and am I right in assuming that the uart is 3.3V ?

Thanks for all of your help
Paul.

you can update to 2.06.3(120112.1)
you will find it here :

http://hotfile.com/dl/142100356/1d87527/2.06.3_120112.1.zip.html
(MD5 371c00942b43b88df49eb23ca4ede99d)

right, it is 2mm pitch and 3.3V level UART

Thank you tinhead, I now have a working scope again. (DSO5102B  hw 83e8)
Without your help I would be sending it back to china and hoping for a warranty repair, which would probably cost a lot in delivery and take a few weeks for it to be returned.

I only deleted the /param/sav/run file (I only found one) and it booted up OK, if it didnt I was going to try the other files in /param/sav/udisk.

I still think this is a bug in the current firmware 111226, (its still the latest available on the Hantek website) as I didnt have any problems until I upgraded.

Can it be downgrade to a older firmware ? I am a bit reluctant to upgrade again :(  (although I have downloaded the link)

Thank you again
Paul.

don't worry, the latest version here is working better as the latest version on Hantek website.

I remember i developed downgrade firmware ... here is it
https://www.eevblog.com/forum/index.php?topic=1571.msg63001#msg63001

It should work with 83e8 hw1007 (i would not recommend to install it on hw1007 83e9)
So you can try it, if you not happy you can still install the latest fw again.

it would be helpful if all the firmware Updates are for example on the first page.

THEY ARE ON FIRST PAGE!

i'm trying always to maintain this thread, deleting old fw/tools, updating all the links on the first page ...
so all ppl have to do is check there ...
I don't want to be human! I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter ...
I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me.

Hi
I just receive my DSO5102B
First I change it into DSO5202B and everything works great. Thanks for great job with reverese engineering.
Now I have a HW 10070 of PCB and there is a space on it for RJ45 for LAN and I wonder if it is possible to just add this connector and enable this option in firmware???

There is an instruction on page 70 on how to connect LAN using $5 USB dongle.

sobomax :

I think I have looked everywhere but I can't seem to find your network adapter supported list. :(

Also, any code updates ?

Hey Douglas, not much happening here really. I don't have any hardware list, but you can just take release notes for the 2.6.13 kernel and see what is supported there. This should give you a pretty good idea. Or you can just take your laptor with the i386 version of 2.6.13 running in the virtual machine to the shop and try to plug few and see which one works.

The kernel itself is now online here: https://github.com/sobomax/hantek_dso_kernel

Right now it's just stock qq2440 code, but in the next hour or so I will be checking in some small fixes required to build it with the recent 4.x gcc. The original code still assumes 3.4.

@patz:

Is it possible to add an option to your software which allows me to change back to the 1062b and not only one way to 1202b?

best regards
Johannes

Hi,

should be possible, I'll have a look at it ASAP.

Sorry, Patz,

I was impatient   :-[ .

I extended your sources to switch between all bandwidthes at will.
