Sniffing the Rigol's internal I2C bus

any idea what is happening/what I'm doing wrong?

The guide I wrote on page 208 of this thread is pretty much a direct copypaste of what I did, the only difference being that I've obscured my serial numbers. Check the screen of the scope after you enter the :syst:opt:inst and look for a progress bar. If you don't get one, maybe try and restart the scope… Of course you could just enter the license manually on the scope screen if the :system:option:install doesn't work.

DS2000A Firmware update 00.03.00 is available.

I did.. I just used info from Arkku's guide since it omits installing viva? drivers (I am on linux at the moment) and fiddling with a text editor.

The scope says 'license is unavailable!' (no progress bar) when using the onscreen editor as well.. restarting doesn't change anything.. I suspect something is wrong with the generated key.. Why, I don't know... I will see if I can find a windows box and try the precompiled version of rigup (does anyone know if the 02 version generates the same keys as 01?), because when I compiled it, I got some warnings about uninitialized variables.. otherwise something probably goes wrong when applying the ruby script..

I think I've come across some sort of tamper-counter, because now the scope has stopped responding to any license I throw at it, both over LAN and in the user interface (no 'license is unavailable' message anymore, no reaction whatsoever).. power off, etc, doesn't help..
another discovery is that the windows exe from the gotroot.ca rigup02.rar archive does *not* produce the same licenses as the home-built one from rigup-0.1.zip (built just by issuing 'make'), i.e. the two versions produce different output when doing e.g. 'rigup license scopekeys.txt NS8H'.
They do produce the same licenses when invoked using 'rigup ds2072a scope.bin', however..

There are multiple solutions to a valid license so it isn't necessarily a big deal that you get two different outputs.
