Hacking the HDO1k/HDO4k Rigol 12 bit scope

[skander36]

I have also take into account a mecanical or soldering problem but moving/pushing/acting in mechanical way does not make a difference neither when it was not working nor when it is working.
LE. I didn't have skipping problems with that knob. Push has always worked. Just increment/decrement was not active.

Apart HW code all the rest is the same, if you have not messed up something in the scope file system you probably have a defective knob's encoder.

I just spotted a FW .GEL file in the scope filesystem (HDO4000Update.GEL) :

dunno if this come with the instrument or it was downloaded by the scope first time it went online.

Looking at FPGA bin filenames and  readme.txt content it seems my scope mount an XC7A100T FPGA model.

I wasn't try to modify something without not knowing what I'm doing

I'm not saying you were messing intentionally something, but if you "operated" the file system in any way there is always the possibility of an unwanted / undetected "accident".

Dunno if there is an hidden menu with a real "reset to factory" function that clears the most as for android smartphones, the default button only affects operating parameters.

Anyhow, is your flex knob 1 working now ?

[skander36]

Yes my knob function flawless now. I am not able to reproduce previous malfunction ...

Yes, press "vol down" + "power" to go into recovery mode...     I wonder if there is something like that here...

Silly question : what action cured the malfunction ?

It would make sense considering what happens with Android APP data cache mechanisms, maybe a function added to the equivalent of MSO5K secret menu.

Can you send me all those files so I can add it to the firmware repo? thanks!

(I think the update file will contain everything else, but the 'build_gel.sh' script also looks _very_ interesting to me

I looked for the "vol down" button but I couldn't find it.

Absolutely nothing. When I checked, it works.

Check PM.

I just played a little bit with DSO FAN, a microphone and a audio spectrum analyzer in order to obtain FAN speed regulation curve, see attached image.

It's clear that PWM duty setting is treated before to be applied to actual HW peripheral, Zero duty  is not Zero RPM so at least we have an offset applied :

Rigol.eu has just published on its support page a new firmware upgrade for DHO4000 (00.02.04), dunno if this could help our hacking experts

Interesting that there's insufficient space on the FPGA to fit the Bode Plot application so that is an independent bitstream. How long does it take to switch mode?

No, just GEL file, also had to update my 7zip version to get the .rar to open.
I'll send them an email see if they say anything. Might be on the CN site as well (but hard to access).

edit: still no response to the email.

No release note and no FW package for DHO1000 ... 4K gets second FW upgrade, 1K gets nothing at all 

[black_cat]

This firmware can be used for hdo1000

[markone]

This firmware can be used for hdo1000

I ventured in the process, my scope (HDO1074) does not accept it, I got to point the GEL file but the system does not proceed.

[markone]

I wonder if any owners of the HDO4K scopes are following this forum, if positive I would be glad to know what bugs were fixed by the 2 published FW upgrades.

[Martin72]

Normally the fw upgrades are coming with upgrade instructions and release notes (download and see last MSO5000 firmware).
Very unprofessional behaviour from rigol.
I wouldn´t upgrade the scope when I don´t know what have been changed.

I agree if your current FW is working in a decent way, otherwise you do not have a lot to lose.

Current HDO1K firmware is at best an alpha version, I do not know how HDO4K's models are performing right now after 2 FW upgrades reason why I asked about that in my previous post.

But it seems that here no one ventured to buy a 4K model, but I can understand it   

Maybe COVID 19 is really hitting hard China as west world is telling every day.

User @dschiedsch has an HDO4K. Maybe he has test the new Fw. version.
