Sniffing the Rigol's internal I2C bus

[alank2]

I find this report of 2302 to be quite odd, but looking at the firmware does show a place where it says DS2072 and then has 07, then 10, then 20, then 30.  If you can assume that the 4 two byte sequences replace the 07 in the DS2072 then it is possible that this version of firmware which has been out for awhile does actually support a DS2302.  The question is how to enable it.  Could it be that some bits in the 3rd group are also additional option bits like what was found with the 3rd group for the ds1000z?

Could the firmware on niffler's have the same version, but actually be different than the firmware version we have all upgraded to?  He said he did not have to upgrade it...

I have been told (no I will not tell you who, but it is a very reliable source) that the DS2072 can be enhanced to 50 Ohm termination, 300 Mhz AND also to CAN protocol.....
Though I do not know if this is possible just by entering a code or by writing new stuff through the JTAG into it but I doubt the latter.

You mean the DS2072A right ?. The DS2072 (HW version 1.0) does not have a 50ohm termination build in  ...

Probably just a firmware update from Rigol once the DS2000A becomes available (same firmware)

[apelly]

My 2072A should get here on Tuesday. Monday is a holiday here.

What do you want me to do with it? Aside from pics & firmware version obviously.

(Try to) Hack it! Use the keygen provided on this forum and see if you can successfully turn it into a 200MHz scope with 56MPts memory and all the bells and whistles

Has anyone else besides niffler tried a DSAZ key on a hardware 1.0.2.0.0 version to see if it also shows DS2302?

[davidefa]

I think that several of us tried DSAZ.
I have same system info as niffler and AndreaEl ( only 'manufacturing week' is different, week=27 ).
Now my scope is DS2202 ( sticker still DS2072 ;-)

[davidefa]

Serial of apelly starts with DS2D ( DS2072A ). Our starts with DS2A ( DS2072 )

How do you get the extended system information? I read it somewhere but I can't find it now.

From Marmad's post on another thread:

"Go to the Trigger menu and set Edge trigger.
While keeping the Trigger menu open, you are going to use the 6th and 7th right-side menu buttons as follows:
Press the [Menu7][Menu6][Menu7][Utility] buttons one after another quickly.
Then check additional info under System -> System Info."

Aha. 

[engr_rf]

Is it possible to get extended system information on the DSA815?

[olsenn]

For god sakes man, can it be hacked?!! Haha, my mouth is watering thinking about this damn scope.

[van-c]

Yeah, my sentiments exactly.  In fact, I have an order in for a DS2072 due to ship in a week that I'm trying to decide whether to postpone and wait for the DS2072A.   But once current DS2000 shipments are made, there may no longer be any of the original models. And with the total lack of test results on the "A" models, I'm not willing to take the gamble.

[apelly]

At first glance, my new DP832 and DS2072A appear to be immune to the key generators in this thread.

Could have been a typo. Will fool around some more tomorrow.

Hi,
I used the keygen to upgrade my DS2072 to a full option DS2022 model, and this works great. Thank you lots guys!
But it also did reset my Serial Number to DS2A000000001. Is there a way to reprogram the original serial (which I know) without actually opening the device and reprogramming the EEPROM directly?

What version of the FW had you before the install of the key? Before install key is better install latest FW for not delete the serial #.

I had 00.01.01.00.02, the latest available version. I did the upgrade, then installed keys, and then it did not boot up anymore. So I had to do the upgrade again, and then I had DS2A000000001 serial. I installed the keys again with this serial and everything works OK, but it could be much better if I could recover the original serial, in case Rigol checks that in future upgrades.

May I ask a silly question?

Is HW 2.0 version hackable (DS2072A)?

I am going to buy Rigol, but don't know which version works with hack...

Sorry I am messing in the thread a little bit but most of people forgot to write their HW number.

Looks like there are earlier version HW 2 and newer... Am I correct? Which HW revisions are hackable?

There are:

DSDS2XX2 ----- HW 1.0 ----- Hackable with latest FW No sell new
DSDS2XX2 ----- HW 2.0 ----- Hackable with latest FW (I have this one) Can buy NEW

DSDS2XX2A ----- HW 2.0 ----- NOT HACKABLE ----- Can buy NEW ----- See Reply #1275

If someone can confirm this, I'm not sure about DSDS2XX2A, no much people have this. in future maybe can be possible hack this one!!

[bobn4burton]

So I just ordered a DS2072 and am hoping to do the mod to DS2202.  I got a good deal on a refurb unit!  I will admit that I haven't read this whole thread yet...just scanned over parts of it.

I am wondering if there is a good place that compiles all the needed info into a step by step procedure?  I have looked at this:

http://freneticrapport.blogspot.com/2013/07/raspberry-pi-rigol-ds2072-200mhz.html

Is there a better or more current place to step me through the process?  Maybe even a page/post in this thread I should look at?  Or another web link?

I am a newbie to all this...
Thanks in advance!!

If he couldn't get it to work on his DP832 either then I'm guessing he is just using the keygen incorrectly. Not necessarily, but likely. We'll see as more DS2000A units arrive.
