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

[tinhead]

Did anyone try to hack DSO5102BM?
I bought DSO5102BM few days ago only and wanted to hack it.
 But I noticed it uses a different software.
E.g. I need not use
 killall dsod command
to enter console and also  booting is different.
I were not able to change logo and not sure if the hack was really successful.
It shows DSO5202B( as I wanted) but not sure if it also works as DSO5202B.

Besides when it starts booting it shows

Thanks for help.

BM/BMV models are newer, there are few differences:
- logo is not just a bitmap loaded during boot process but it is located in the "disp" executable (/disp or /dso/app/disp)
- current BM/BMV firmware is based on older B-model sources (from Nov/Dec 2011?), so some changes are not
  implemented yet. One of these changes is watchdog (dsod executable), if not there you don't need to kill it.
- bootloader is different(better), it does support now USB upload
- kernel is 2.6.30.4 and not 2.6.13
- root fs is newer, contains newer drivers, media player, etc.

All you need to know is, when 2ns/div timebase is there then the hack was successful.

thanks for the reply.
Does it mean BM/BMV models has also different hardware or only software?
I noticed there is P1 connector for buzzer but nothing more different

And is there a way  how  I can  change the logo also?
Thanks again for help

Wat?

[project]

For those whose ever got error code 0xfe when update by usb, just change the file name to dst1kb.up, u'll survive.

I was trying to update 120430, to 120623 and 120808, dso refuse to recognize file on usb in long form, keep gave me 0xfe error. after I read https://www.eevblog.com/forum/index.php?topic=1571.msg70890#msg70890 . Thought might be file name too long or something wrong with my computer, just change the file name to shortest one that dso needs to know, that is dst1kb.up, problem solved. just FYI.

- root fs is newer, contains newer drivers, media player, etc.

Wat?

yep, BMV models supports "Video help", which is nothing else than Video player (with some video help files).
The video player is actually mplayer from http://www.mplayerhq.hu

Hi tinhead!
I purchased oscilloscope TEKWAY DST1062B.
Model: dst1062b
Software Version: 2.06.3 (111,122.0)
Hardware version: 10070 × 555583e8
Product No.: T1G/012005503
After the upgrade, start oscilloscope LOGO displayed as DST1202B. However, in view system information or DST1062B. This question should be how to deal with? Please help answer, thank you!

[tinhead]

Does it mean BM/BMV models has also different hardware or only software?
I noticed there is P1 connector for buzzer but nothing more different

no, the hardware is the same (except bigger SRAM chip)

And is there a way  how  I can  change the logo also?

sure, you can edit the "disp" file and replace the logo picture by what so ever you like

[yoq]

hi tinhead,

you seem to be online right now, so what do you think about network on the bench models?
please see my post on page 92

Thank you

EDIT: From what I can read, network access works on the BM(V) models, would it be possible to run this firmware on the 5XX2B hardware?

[tinhead]

A few people mentioned WiFi dongles, and I really liked that idea, so I got a 10€ one from amazon.
It has a realtek chipset, and they provide linux sources for the driver.
...
If you have a different dongle than the _{EDIMAX EW-7811UN}

good work, thanks for that.

@tinhead
Is there any chance of getting network support for the DSO-app on the bench models?
I tried to activate it by writing the [net]1 to the EEPROM, but I couldn't connect with ttscope or dreisiebners' dso-tool.
Taking a screenshot wirelessly seems like a very neat feature to me, so already tried to grab it directly from the framebuffer, but /dev/fb0 seems to be unused.

unfortunately only the handheld version of dso.exe can use network directly. In principle with BM/BMV benchtops
root fs it's possible to run the handheld dso.exe (tested). However such combination does NOT work with benchtop
frontpanel layout, so not a real option

I've asked multpile times both Hantek and Tekway why they still not released network-enabled
firmware for B/BM/BMV/MSO benchtop models, the answer was always "soon".

I've compared the speed over network and usb (with handheld), and network was much faster and stable,
so no idea why they still not released it officialy.

Anyway, there is another way: the network communication works over UDP, port 9966 by default.
Because its still the same data, all you need is to redirect the USB data to network.
Im principle a UDP server and patched usb-char i think? (from usbdevice driver) could work as well.

[Jane]

@tinhead:You say I can change logo by editing disp file.
Do you mean

/logotype.dis
file ?

I changed
/logotype.dis
It consists only
hantek_DSO5202B

But still no good

Thanks for reply

[yoq]

In principle a UDP server and patched usb-char i think? (from usbdevice driver) could work as well.

Thanks for the good idea, i got it working! Hantek released the source code for the usb-char module, so it was relatively easy to redirect all communication to a udp server. For this, I wrote a new kernel module using the nice ksocket library/module.
I will clean up the code a bit and post the sources tomorrow.

no, the disp file. Just check the file system, there is /disp or /dso/app/disp file, and inside this file a
raw image is included (in principle like the logo files before but this time compiled into executable file)
You can replace/edit this file to create own disp file - for our model the logotype.dis is not changing anything.

a big thumbs up! 

that was fast solved.

[yoq]

Okay, so here are the sources for the usb-char module with integrated udp-server.
The redirection via UDP only becomes active when the there is no USB cable from the back connector to a PC. Unfortunately the detection whether the cable has been removed is not very reliable, so it often takes a restart to use UDP again after disconnecting USB.
The zip contains the compiled modules (ksocket, udp_server, usb-char, load in that order), and the sources.

[tinhead]

nice.

out of curiosity, which version of GPL code did you used,

http://www.eedownload.com:7635/dso_bench.zip
or
http://www.hantek.com/download/desktop.zip
?

Side note:
The desktop.zip contains (especialy the first version which has been already removed from web)
some more drivers, the last one contains however no real source for usb client.
I've attached (in case somene need it) drivers from first version of desktop.zip,
the usb client was in linux-2.6.13_800x480_option1_lz_120410.tar.gz\win\2.4.18usbd\


The dso_bench.zip contains the "the real" sources of usb client driver.
For some reason both Tekway/Hantek was not able to find the proper (original) sources,
finally they found something (what will produce similar binary driver as the one in DSO root fs)
and included in the dso_bench.zip

[yoq]

I used the driver sources from the voltcraft package (http://ftp.gpl-devices.org/pub/vendors/Voltcraft), they are identical with the drivers_2.6.13_lz_120410.tar.gz from your zip file. I also had to use the our_s3c2440_regs.h from the option1 package as the kernel sources only included a symbolic link to a file on their disk. Everything was compiled with the arm-linux- toolchain, version 3.4.1 from the voltcraft package.

[Polossatik]

All you will have to do is to:
- backup firmware (over USB flash drive with backup tool)
- remove sticker (front panel near USB) to expose the hole for DB25 socket. Every hw1007 have such hole.
- solder cable to DB25 socket (the IDT20 cable which will be pluged into LA PCB)
- mount this DB25 socket to front panel. I think there are already holes in the shielding, when you remove the sticker
  you will see immediately if there is any drill work necessary.
- solder the 1.27mm pitch header to DSO PCB
- mount the LA PCB to DSO PCB
- connect the IDT20 cable (from DB25) to LA
- reconnect all other DSO cables, so you can boot DSO.

Boot DSO and install new firmware. You will need for this UART<->PC connection and deatiled description how to
do this. I will get special crafted firmware (actually complette dump), this must be complettly restored to DSO
overwriting the old version. The biggest advantage : you will have newer Linux version, which is anyway necessary to
get network working. In Germany i'm offering "instalaltion service", so everybody who don't wish to play with
UART/USB to install firmware or solder cables/header can get this step done by me (for a small fee).

So as long you have :
- screwdriver
- solder station
- UART<->USB adapter cable
- max 2GB USB flash drive
it's not so much to do.

just saw this, so had a look at the Voltcraft DSO-3062C  hw1007 version
there is a hole in the plastic of the case for the DB25 socket in the front panel, but there is a metal shield behind it, is the clearing between those enough to install the DB25 socket ?

edit: ha, having second look at http://www.tekwayins.com/pic/201202080007.jpg it measn you need to cut you're own hole in the metal to mount the db25... hum..

and what's up with those unpopulated phone/mic things next to the rear USB port? where are they used for in other models?
I also don't see any models with a second front usb port, anyway, info about that must be buried most likely somewhere here in the thread

Tinhead, but how can I change the  logo of DSO5102BM, if the   /dso/app/disp file is already compiled?How can I edit a  compiled file?
Thanks for your reply

Standing Ovation and Thanks to Tinhead

Hello all,

I am new to EEV Blog and found Tinhead's post concerning the Hantek ~ Tekway mods while Googling for a Hantek seller ~ distributor.

As an Electronic Tech, ( and for the time being, still gainfully employed , LoL ! ) , I would like to encourage my other unknown colleagues and individuals  that have benefited from Tinhead's research and much shared assistance and Donate to him through Pay Pal.

While others have also freely shared on this forum and others, as an ET I fully realize the time and effort Tinhead has dedicated and been able to share info because of his connections , ( or at times his Dis-Connections ? ),  with the DSO  manufacture~s.

If one was interested in donating how to do it?
I bought a MSO board from him so I have the info, other than that you might try to PM , ( Private Message ), him.

For those that may wonder, other than using his DSO Mod info,,,No, I do not work for or am I associated with anything Tinhead does.
I am just Thankful he has shared the info.

Respectfully, Fet

right, but the metal frame is behind front panel, so you don't need to worry about "the quality" of the cut.
So for Hantek/Voltraft owners not a big deal, for Tekway owners a bit more work as they have no hole
in the Frontpanel. Still not tragic, but yeah, additional step.

and what's up with those unpopulated phone/mic things next to the rear USB port? where are they used for in other models?
I also don't see any models with a second front usb port, anyway, info about that must be buried most likely somewhere here in the thread

a few ppl here (e.g. Jane two postings above) bought these BM/BMV models, so they can answer you if there is
the mic/phone populated. The second USB port, well, it is not only question of changed USB driver but also additional menu
in the firmware to allow port switching (client/host), and i seems HanTekway have not ime for such extras

[Polossatik]

cheers Tinhead, you've got a PM

After reading the thread, I feel the hantek ds05062b would be a nice dso over owon sds7102 and rigol ds1102e. Anyone feels owon will change their firmware as they have excellent hardware but crappy UI.

Thanks,
Tim

[tinhead]

what a pain, Extech is now selling "B/BV series" Hantek Handhelds (that's these based on the same architecture as
the benchtops int his thread) - where Extech MS6060 is Hantek DST1062BV, and so on.

So far nothing new with Extech, but look at the price:

http://www.extech.com/instruments/product.asp?catid=16&prodid=694
http://www.extech.com/instruments/product.asp?catid=16&prodid=695
http://www.extech.com/instruments/product.asp?catid=16&prodid=696

I would say, before you buy one from Extech, buy 2+pcs from Hantek, hehe.

[Bored@Work]

I would say, before you buy from Extech but 2+pcs from Hante, hehe.

But, but, but, Extech is soooo ISO9000 certified. That is for sure worth the higher price ... *ducks and runs*

[tlu]

Hi Tinhead,

I saw there is also the Hantek DSO5062B, BM, and BMV model. Reading up on them the BM has an extra 1M memory and the BMV has the extra memory and video help as well. Do you know if both of the latter models are hackable to 200mhz with your method? I wouldn't mind the extra memory but do you know what the video does for BMV model?

Thanks,
Tim
