Sniffing the Rigol's internal I2C bus
poida_pie:
What chances are there to patch a firmware so that it outputs the key and serial when you send it
"*IDN?". That would be good.

Generated from the serial number perhaps?

I think so, but only Rigol knows the algorithm.

Does http://www.rigol.com/account/user.php?act=license have anything to do with this?

The keys in these dumps are different, so it seems highly probable that every unit has its own keys. Consequently, it won't be possible to use the new keygen without extracting keys from the scope's memory (either flash or DRAM).

I expected that, it proves why it didn't work with mine
btw, sorry if this was explained already, but the 300 MHz (untested) option doesn't seem to work
does it mean that it's not implemented with an option?
somehow 12 MHz JTAG speed feels like the 5 MHz in the how-to, 8 MHz seem faster than 12 (and 5)

Got TIAO JTAG adapter now. I hope I have time to dump at weekend. One more week 42 dump in making :)
42, 42, 42, something is hidden here ...

Hi, using a site like this, is it possible to disable 500uV mode? I didn't know about the uncalibrated offset.
