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

[pishta]

Just purchased a DSO5102P, was looking to calibrate some old car audio CD changers. My device only had 7 bootcounts on it when I purchased it $100 used! Still has sheet on LCD....Well, the thing already goes down to 2ns (200MHz?) the test Hz indicator bounces around with no probes inserted and I saw it go as high as 102.3MHz with this system info:

Model     DSO5102P
sw ver   3.40.0(170630.0)
hw ver   1010xffff8108
serial     T 1G/138 008439
boot cnt 9
upgrade 0
LCD f ts 3.3.0

Does anyone have the HDL for the FPGA used in this scope or at least which FPGA pins are used for which function? That would go a long way in being able to replace the UI software on the scope and perhaps fix some of its issues (such as terrible triggering and lack of sync between the scope and LA parts)

I know there's a FriendlyARM board that can be used for SW development but the actual "scope side" stuff would be great to get at as well.

Heheh that is not really a "conspiracy" theory because conspiracy means something illegal.    There is nothing illegal (at least in the USA) about not enforcing your rights.    (Otherwise they would legally be called "Obligations" :-) )

Thanks,

Please tell me where I can find detail information of this equipment, I didn't find it on website.

Hi everyone,

I just revived a friend's Hantek DSO5072P that had stopped booting after only 3 hrs (!) of normal use. Turned out it had a corruped NAND flash. Bootloader was fine but it didn't even extract the Linux kernel any more.

Here are some things I had to research that might help others:

1. The 5000P series unlike earlier 5000 series can AFAIK not be flashed via USB. There is no supervivi bootloader available that runs on its newer SoC and the factory uboot bootloader can only flash what fits into the system's 64MB of RAM (the firmware image is 128MB). So your best bet is using JTAG.

2. If you don't have a complete firmware image from a 5000P series scope (not a 5000B or whatever other 5000 series) you are f***ed. Hantek only provides firmware updates, not complete firmwares. Luckily someone provided his fw_backup.bin on this thread.

3. A post by minescumarius was extremely helpful. It includes a config file for the H-JTAG software and pinout of the header. Cheers Mate!

4. If you dont' feel like making your own interface, you can get one for 5 bucks shipped on aliexpress. The schematic minescumarius provided is exactly what is known as an 'ARM JTAG Wiggler (clone)'. Be warned: This needs a hardware parallel port - not some USB->LPT converter, not even a Thinkpad T60 ultrabay COM/LPT adapter worked.
Also I could not get H-JTAG working with that parallel port under Windows 7 x64, had to run it on a 32 bit version of Win 7, driver issue most likely.

I had some initial trouble getting H-JTAG to even detect my MCU - Only after I connected the two reset lines to the board I got it to work.
Also my flash process would stop with various errors until I realized that the 1 meter ribbon cable that came included with the 5$ Wiggler was a bit on the long side for signal integrity. Clipped a ferrite bead on there and all troubles were gone. You might want to use a shorter calbe or try the same.

5. Flash process took me around 200min at 11kB/s, so be patient.

I did the hack to convert my DSO5102B to a DSO5202B some years ago which went well. The last firmware update was back in 2013. I recently tried to update the firmware but it I get Error: 0xfe  No upgrade files detected on USB device. 
   What do I do to be able to update the firmware on the scope?
      Thanks for any help!!
 
Model: DSO5202B
SW Vers: 2.06.3(130814.1)
HW Vers: 10070x555583ED

Hi christensen,
I realize yours is quite an old post but did you complete the LAN modification successfully?  I'd like to do the same but haven't found the instructions yet.  In fact, I'd like to do all the mods for my Hantek DSO1202B v2.01.1 (add SD, video, net), just to learn how to do them and gain some experience.  Thanks for any help.

download from my 1drv, from firmware, version, model folder the proper/latest file.

There is even a way to run firmware from Feb 2018 on hw1007 platform (like i do on my old hw1007),
but it's bit tricky (one have to copy over ssh some libs first, updates can be done only over lan/uart by copying latest only executable file).

Thank you!

Just open your favourite search engine and look for Hantek2D42
It came up on banggearwatch, banggood, and Amazon. Banggood has the pic u posted.
not related to this thread, but since its been viewed a few hundred times...

Hey lads,

There's a new firmware release on the hantek site dated yesterday or the day before 3.40.0(190125.0), that makes it one year and five days since the latest update 3.40.0(180120.0)
The changed files are show_pic and dso.exe.

A plain dumb strings diff suggests at least some bugfixes .. so it might worth testing this against your favourite bugs.

Happy upgrade.
Cheers,

[WanaGo]

For the DSO1152S I was sent new firmware yesterday by Hantek, however it does not appear to be on the website. Last on the website was 170801 and this is 180821.
Would love to know what changed if someone can assist with that.
My model is quite old, 2012 PCB 1.00.1 so I am hesitant to upgrade in case it kills it.
Here it is for a limited time: https://1drv.ms/u/s!Ak2DUCelcmmIg_oPxDmU62g0q9g_0A

Thanks

Hi,

for which models ist the update?

I did check the Hantek page for the DSO5000B updates, but did not find the version you have mentioned.
So it is probably for a different model(?).

Regards
Chris

[llg]

You are right, sorry for the noise.
It's only for P models, DSO5000P.
I've checked 5072P and 5202P and assumed they updated all models,
but it's only for P.

Hey llg, can you just explain how you did the compare exactly?
How do you extract anything out of these up files? Im sure I use to know, but its been too long.
Would love to find out what changed on my update above.
Thanks

If your machine is showing the 2ns out the box the 200MHz upgrade is already done. I got my 5102p from Amazon around a month ago and it was already done from the factory. I have seen quite a few others the same.

Enjoy! 

Very interesting.
I don't know if this matters or not, but after checking the FW, it would appear that it is using the 5072P according to the Hantek website.

Just bought my 5102P and learning to use it. What do you mean about the 2 ns thing ?
That only models with 200 MHz have that 2 ns resolution ?

[GilbouFR]

Just bought mine and got it since last saturday.
It's a 5102P 100 MHz
Upgraded firmware to 3.40.0 dated 25-JANUARY-2019
hardware revision 1010xffff8108
Goes down to 2 ns

If it goes down to 2nS then the 200MHz upgrade is already done right from the factory.

It is explained better here.... 

 

[GilbouFR]

Yup. Mine goes down to 2 ns   
I ordered two 200 MHz probes to replace the PP-150 model I received with the DSO

A very good surprise to get a 200 MHz when I bought a 100 Mhz 

[WanaGo]

I thought it was mentioned some time ago that the 2ns feature is no longer an indication that the hack worked, or that its 200Mhz.
It comes as default now, but doesnt mean you have 200Mhz enabled.
May be wrong, but I am sure I read that on here from Tinhead

[Terry01]

Can someone please explain if this is the case or not? Is it 200MHz enabled or not? I have no idea how to work this out so I am repeating things I saw others said or wrote or whatever when this 1st came up.

Again, I do not know how to work this out so am not arguing either way. Just looking for someone to nail it either yay or nay!

I remember when this first came up someone said it was rubbish and not so 200MHz. Someone else did the calculations and posted them to show everyone how it was worked out and then everyone agreed the 2ns thing did mean it was 200MHz enabled.

that's right, depending on firmware/hardware/models it can be still e.g. 100MHz BW with 2ns/DIV enabled. I do not track which models/fw/hw are affected, so easiest way is just give a try and measure 200MHz signal connected to input (directly, because with slower models one get slower probes anyway) right before and after hack. It can be simply XO, what so ever, or even diy pulse generator

[GilbouFR]

I don't have the hardware to generate a signal high enough in frequency to test.
I'm learning for now so my use of the DSO is very basic and simple and besides a crappy chinese DSO generator I don't have a proper and proper generator or anything at 200 MHz.
I guess a basic 50 MHz would have been enough for me anyway 

[indman]

Here real characteristics of modern releases of DSO5102P:
Amplitude-frequency characteristic of one (any) channel at the switched-off other channel
1mV/div: 25Mhz (-3dB); 50Mhz (-6dB); 100Mhz (-12dB). Scope of noise 0.4 divisions.
2mV-2V/div:<40Mhz(0dB);70Mhz(+3dB);100Mhz(0dB);120Mhz(-3dB);140MHz(-6dB). Scope of noise 0.1-0.2 divisions.
When giving one signal on 2 channels (through cables of identical length) oscillograms are shifted rather each other on 2ns.
The shift is visible on horizontal sweep of an oscillograph <40ns/div.For this reason mathematical operations have normal (+-10%) to frequency 10Mhz.
The mode (X-Y) normally works only to 20kHz.With the included afterglow to 3Mhz.
As a result - in the 2nd the channel mode the DSO5102P normally works (+-10%) to 10Mhz, in 1nd the channel mode witch measurements (+-10%) to 40Mhz.
As the indicator - to 140Mhz.
CH1 and CH2:Rin=1MOhm;Cin=20pF; Ext.trigger:Rin=1MOhm;Cin=16.5pF
Probes (x1):R=332Ohm;C=96pF;works frequency to 7MHz(-3dB)
Probes (x10):Rin=10MOhm;Cin=16.5pF to frequency 120MHz(-3dB)
