Sniffing the Rigol's internal I2C bus

neslekkim:
Read the url I posted right above your question, everything is written there..
you only need the hacked firmware to get the keys out, save them, and use rigup to create the license.
You can choose to revert to latest official firmware, no need to keep the hacked in the scope.

GlassFET:
That's wonderful. Thanks to all.

I just need to understand which method is better, and figure out which firmware is which etc. I guess I'll try and slug through the whole thread.

In the interest of future n00bs, please do. Write a summary of the installation procedure that is easy to follow for others I mean. Otherwise you are just another "me too" never to be heard of again after they fixed stuff for themselves. :P See enough of that shit in other threads already. ;) Notably the Flir E4 thread.

That was exactly what I was trying to avoid -- I am not by any means new to forums. I've been using them for almost ten years and I know the etiquette. However, I also know what constitutes a good, well-organized thread -- and this is far from it. I understand that the easier it is, the more Rigol will try and stomp it out, but that will never fully happen. As long as you can update firmware, the hacks we have now will never be undone.

Plus, if I do make a video and instructions, I will re-host all the files myself, and post it elsewhere so it doesn't get fully associated. As soon as I have a walkthrough video done I will let interested parties know.

I've done this Hack on my DS2072A-S, so if it works with this one, it will also work with any other 2xxx.
Here is, what you have to do:

1) Download https://mega.co.nz/#!MdcEWTgL!0EEmSr-Q6TxaFSsyEmjhRrgqDvFCoXg9K49BalL5Uxc
2) Install this firmware during bootup - check Rigol's guide on how to do that
3) Connect the scope to a PC using USB.
4) Install and start "Rigol Ultra Sigma", right click on your scope, open "SCPI Control Panel" and "Send&Read" string "*IDN?"
5) Copy string from comma after serial # of your DS2xxxA to the end ("02008400...").
6) Open HEX editor, create a new file and paste string as HEX (not ASCII).
7) Copy serial # of your DS2xxxA.
8) Append serial # as ASCII to the data in HEX editor.
9) Append "00" as HEX.
10) Save file as "keyfile.bin" to folder with "rigup" (https://mega.co.nz/#!qAkUkTZB!XG12bUKhIz4CmQt6DbBnGRMvEe5AvUjEaBxi4R03tw8).
11) Open command line and navigate to folder with "rigup".
12) Execute "rigup scan keyfile.bin" and get some keys:

RC5KEY1:        88359067012Exxxxxxxxxxxxxxxxxxx
RC5KEY2:        3D44CD4EC48Fxxxxxxxxxxxxxxxxxxx
XXTEAKEY:       95F6CC12864Axxxxxxxxxxxxxxxxxxx
PUBKEY:         006CE7F7xxxxxxxx
PRIVKEY:        008ABBC4xxxxxxxx
SERIAL:         DS2D154xxxxxx

13) Copy them to another text file "keyfile.txt" in "rigup" folder.
14) Execute "rigup license keyfile.txt NSxx", where:

NSEH (0x1C087) - All options
NSER (0x1C08F) - 100 MHz + all options
NSEQ (0x1C097) - 200 MHz + all options
NS8H (0x1C0C7) - 300 MHz + all options

15) Copy license key.
16) In "Rigol Ultra Sigma" -> "SCPI Control Panel"" -> "Send&Read" ":SYSTem:OPTion:INSTall YOURLICENSEKEYWITHOUTDASHES".

This is Variant b.
Thx Fagear for the instructions and of course big thanks to zombie28 and tirulerbach, who made this hack possible!

--- Quote from: Wall-E on January 21, 2014, 11:35:25 pm ---It's now Firmware version  00.01.09 for the DP800 Series including the DP832 (non A).  And I understand that it's not good news with all options lost, and no way to go back to FW 06, or 08.

Note: This Firmware has been provided to DP832 (non A) users by Rigol for those that had requested a FW Update for their units.

Ref.  RIGOL DP832 Power Supply - firmware upgrade, « Reply #36 on: Yesterday at 03:38:23 AM »   Although I don't think Rigol supplied this particular person his FW 09.

In the post you reference, Sebastian states "the Riglol Keys don't work" --- which is no different from 01.08 where they didn't work either (and why people downgraded to 01.06 to install the keys and then upgraded to 01.08). 

How exactly are you concluding "all options lost"?

--- End quote ---

The trick with getting the options in 1.06 and then upgrading to 1.08 never worked for me. If I would install all the options in 1.06 and upgrade to 1.08 everything would be lost, not just the trigger option as other people here report for there units. If I would then go back to 1.06 the options would be there again without entering the codes again.
FW1.09 is essentially the same as 1.08, none of the bugs are fixed, the only difference is that you can not flash older versions anymore because of the new bootloader,

--- End quote ---


Same thing happened to me, I stupidly did the 1.09 upgrade also :palm:
Had it all calibrated in 1.06, but found the bugs too annoying.
Bu**er :scared:
Maybe one day some brlliant person will find a way around this??
