No. At least until now, Hantek updates only affect the dso folder and the fpga firmware.

Thanks for that David, I shall be mindful accordingly.
Interesting; I am running the Hantek upk that was originally installed (dso3kb_20210416) it was so easy to get it to lockup that Hantek sent to me dso3kb_20210510 which was somewhat better.
However since i installed dso3kb_install_lockup_monitor I can't get dso3kb_20210416 to lockup at all

I sent to Hantek support the report of the errors that I detected up to date in my scope (see message https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/msg3591243/#msg3591243) and they have responded that as soon as the responsible engineer solves the first issue, they will contact me again. But for issues 2 and 3 they tell me they are resolved by the following firmware update file that they have sent me:

dso3kb_20210630_auto_update_fpga.upk

In case someone else might need it, I've already uploaded it to the public folder of DavidAlfa's GDrive ('popy5_dsodso3kb_20210630_auto_update_fpga' folder).

Please note that my DSO2D15 scope comes standard with the following software/hardware/firmware:

Software: 1.0.1.1.0 (20210416.00)
Hardware: 000.000.000.000.000.000.000.001
Firmware: 3200

Update: after updating the scope, my firmware version is now 3202.

Tried it. It just changes the fpga fw and the allwinner ADC keypad kernel module (strange because as far as I know it's not used here).
It includes FW 3102 and FW 3202, and a binary that detects the fpga version (I guess if the correct fw was loaded in first place).

Curiously, FW3102 is named 3002. Mi FW3000 changed to 3102. Calibration works correctly, so I wonder if 3102 is just an update for the FW3000.
FW32000 is clearly a different hardware.

They have contacted me again from Hantek support. The new update file resolves the issue 1 sended to Hantek support few days ago (see message https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/msg3591243/#msg3591243):

Quote

Issue 1)

- I turn off channels 1 and 2
- I press the MEASURE button, and then I press F1 (Source)
- When I move the Menu knob to try select CH1 or CH2 (that are deactivated on the screen), the scope freezes and only works again if I turn it OFF and ON.

This issue not appear if CH1 or CH2 (or both) is active.

I think the problem is that when channels 1 and 2 have been deactivated, it should not be possible to choose them in the Source field. However, if only one channel is active, in Source you can only choose that one, but not the one that is deactivated.

The update file is called dso3kb_20210705.upk, and it is already available in the public folder of DavidAlfa's GDrive (folder 'popy5_dso3kb_20210705').

Direct link:

https://drive.google.com/file/d/1o3dSo3dVEcPRq6x6YFAccuV6nTTat9ke/view?usp=sharing

Update: my software version changed from 1.0.1.1.0 (20210416.00) to 1.0.1.1.0 (20210705.00)

excellent news re the new firmware, two in a few days.. Me think hentek about to a new official release :-)

BTW When i took back off my scope I forgot to measure the PSU voltages.
Anyone know what they are as was thinking as soo much spare space inside the back I could add battery's to make it a portable scope?
imk

DavidAlfa · « **Reply #554 on:** July 06, 2021, 06:05:25 pm »

5 for digital , +-8V (symmetric) for analog

Piton · « **Reply #555 on:** July 06, 2021, 06:20:49 pm »

I also have this dependence of channels on each other. It appears in the trigger and in automatic measurements.

imk · « **Reply #556 on:** July 06, 2021, 06:35:03 pm »

DavidAlfa many thanks for the volts :-)
Says on back of scope max 50w and can get off hobbyking 50w 3 cell lipo for $25 or so.
That with few buck convertor and few 3D printed supports should fit nicely inside and give maybe one hour plus of No Mains Required.
Maybe put the buck convertors inside the box and battery in a cradle on the back of case so could easily swap battery out.

Or maybe even easier to get a pure sine 100w inverter and have external mains supply...
--- Ideas welcome ---
Thinking, thanks again ian

20210705 is safe to apply, doesn't modify the FW

Also, I don't know if it was the FW3102 update or the dso app, but the problem when saturating the input at low levels, distorting the signal ang losing the DC coupling, is gone!

However the usb has the issue like 20210510.

popy5, does the usb work correctly for you? Power up the dso with no usb, when it's running plug it in and try hit the save to usb button.
Should simply complain about no usb present. And will start working when you go into utility and hit Update 2-3 times.

Edit:
I restored app 20140416, usb works again as expected. But keeping FW3102, the channel problem is still fixed. So it's the FW3102 what fixes it.

imk · « **Reply #558 on:** July 07, 2021, 07:55:53 am »

David thanks for update on 20210705 will try it later.

Now i have had my DSO2D10 on for two days solid, ch2 input jumpered to gen out.
Every few minutes sitting at my desk i would adjust some function and scope never locked up once in two days.
Then about 4pm yesterday the reinitialization message popped as your reboot mod kicked in.
After the first reboot the scope was very sensitive to any adjustment crashing all the time.
Then the ch2 trace disappeared and displayed an offset voltage of 170 volts.
Then no amount of knob twiddling could i find the trace, so i pressed "Auto Set", normalcy returned and scope was stable for rest of the evening.
Just thought you would like to know your reboot mod works just fine, well tested here :-)

Hello everyone, I decided to join too. I have a 2D10 converted to 2D15, the initial FW 3000. After installing dso3kb_20210630_auto_update_fpga.upk, no changes occurred, the FW version is still 3000. After installing dso3kb_20210705. upk, the SW version became 1.0.1.1.0 (20210705.00), there is no problem with USB.

xuraax · « **Reply #560 on:** July 07, 2021, 12:39:29 pm »

Hi, do you think we should go through ...0630... before installing ...0705...? I current have FW3000 displayed and the April update.

Yes, in my case the usb has always worked fine for me, and now after updating to the dso3kb_20210705.upk, it detects the inserted flash drive without problems (formatted in FAT32), and the captures in BMP format are correctly recorded in it.

David,
I just ran dso3kb_backup_builder util but it didn't produce any backup files, mem stick was unchanged.
It went through the motions progress bar and hardware re init but zero change to the mem stick is 4gb
Photo of my system info below, only deviation is it has the reboot util installed

2nd try, I just tried it again from mem stick i used to bkup from successfully the other day and bkup didn't work again?
Only change is that the lockup monitor is installed, could it be the issue?

Opps, sitting watching the scope and i just did what looked like a power on up sequence Hantek logo full initialization etc.
Didn't look like the locked reboot i had the other day, this was like a power on sequence, any ideas?

Update, removed reboot monitor and backup worked

Final 1145 update installed 0630 then 0705, reboot and recal. Scope for 5 min and locked up, install lockup monitor and testing see 2nd photo 5573.

DavidAlfa
Have you tested the overclock with dso3kb_20210630_auto_update_fpga and/or dso3kb_20210705
If so at what oc speed please?
ian

DavidAlfa · « **Reply #564 on:** July 09, 2021, 01:56:03 am »

Will be the same. Oc won't change.

David, thanks for that.
BTW reading your script, i can't see where you set the core volts could you give me a pointer please?

DavidAlfa · « **Reply #566 on:** July 09, 2021, 06:24:21 am »

You can't. You have to modify the board regulator feedback resistor network. I don't recommend doing so.

Thanks David, that explains why i could fine it.

There was a time when i could solder 40 gauge wire without any aids; glasses etc.
But some years on soldering really fine stuff is now not so easy, hence i'll be keeping to stock vcore.

============ DSO2xxx range ON SALE AT BANGGOOD ==========

https://www.banggood.com/Hantek-DSO2D10-Digital-Oscilloscope-2CH+1CH-Digital-Storage-1GS-or-s-Sampling-Rate-100MHz-Bandwidth-Dual-Channel-Economical-Oscilloscope-with-Signal-Source(AWG)-p-1765904.html?cur_warehouse=CN&rmmds=search

Is this a clue to what happens to the DSO2xxx next, as no new software release for ages!
Pity as I still think it is great little scope for the monies if is was not for all the bugs.
Buy a spare now before they are all gone!

Algoma · « **Reply #569 on:** July 09, 2021, 01:01:33 pm »

BangGood "Flash Sale" on the DSO2D10. The price they're showing to me is the same price as it was before. All they did was raise the "Normal price" to show a bigger discount. Still a better price than most other places. Likely flushing out old stock, now that there are other competitive options at the entry level of this scrap pile. If Hantek can just fix their firmware a bit more, they've got a chance to float theirs back to the top.

imk · « **Reply #570 on:** July 11, 2021, 10:37:49 am »

Hello David,
I have installed 0603 then 0705 updates and this DSO2D10 seems pretty stable with your LockUpMonitor as in two day has only rebooted once, many thanks :-)
So my next DSO2D10 adventure is going to be the overclock, so could you let me know please what OC you are happy with, with respect to best performance/reliability please.
As no point me repeating all the good testing you have done and me locking scope up and having to Platform Tool It etc
Thanks Ian

imk, and in the mode of automatic measurements was checked? Everything is stable for me, except for this mode, and the instability is given by a horizontal scan. If you use only vertical, then there are no freezes.

Piton,
That is about what i am finding with present updates, originally vertical changes would cause lockups.
Now i am finding that only changes to sec/div horizonal timebase changes seem to cause lockups.
However i think running scope in high Mem Depth may also still cause issues.
We are making progress, let us hope Hantek are watching and will release new fix all bugs upk soon :-)

Read the FAQ.
That file just copies the file to the USB, it's not for restoring purposes but for sending it to me in the case your fw version is not in the list.
For backup purposes just use backup builder.

DavidAlfa · « **Reply #574 on:** July 16, 2021, 07:28:45 pm »

New version 20210714 seems to solve the usb issues caused by updates >20210416.
Also menu calibration is different, like old versions that only had "Calibrate" button.
