Sniffing the Rigol's internal I2C bus
conte_vlad:
great :)
I ask: what did not worked on 64 version? rigup or else ultra sigma that send serials?
trunc71:
I cannot say what exactly didn't work on 64-bit. Rigup has created the keys and I tried to send them with ultra sigma and later with Telnet. In both cases I got no response from the DS2072A and the trial licenses were still active. I also tried the update tool which has been programmed by madcrow when I remember correctly. I this case I saw the congratulation screen of the update tool but when I checked the installed licenses I saw the trial ones, only.
On 32-bit I tried the manual procedure first and it worked. Interestingly, the keys created by rigup are exactly the same on both windows versions. It must be another problem, maybe something is wrong with the bus communication. I don't know.
conte_vlad:
thanks for answer :)
it seems rigup, as you said, works same as the keys are same, may be some comunication problems with 64 version. I will do some test, I am afraid to open the unit :-// but I will do

Probably the 64-bit windows version. IIRC the used crypto library had some 32 vs 64-bit issues (on linux as well). So if the windows binary has not been compiled with the correct flags that would indeed cause a mismatch between generated keys on 32-bit vs 64-bit platform.
So when in doubt using a 32-bit VM is a good workaround as already noted.
trunc71:
If that is really the case then I'd expect different keys on both systems. But they are identical what makes perfect sense to me. I have also created the keys with different rigup versions. Also identical. Therefore, when finally transmitting the key to the DOS, the unit cannot know on which system the key was created. But on 64-bit W7 I got no response at all from the DOS whereas on 32-bit I saw the progress bar etc. immediately. I may be completely wrong but at the moment I doubt that the issue has to do with the key calculation.
