Sniffing the Rigol's internal I2C bus

--- Quote from: PeterK13 on December 06, 2013, 08:07:59 am ---Well, the firmware also shows these strings:
CAN
LIN
USB
So, how can somebody enable CAN / LIN / USB protocol analyzer at a DS2072??

The USB may be only for trigger selection, not protocol decoding.
As for LIN, that's not available on either the 4000 or 6000-series, so I doubt that's available in any way.

00.02.01.00.03...

The .GEL firmware name is also exactly the same for both the DS2000 and DS2000A series: DS2000Update.GEL
So maybe the DS2000 series can also be updated with the DS2000A firmware.

DS2072A
DS2102A
DS2202A
DS2302A
MSO2072A
MSO2102A
MSO2202A
MSO2302A
MSO2072
MSO2102
MSO2202
MSO2302

From the .GEL file it looks like Rigol has plans to also release a MSO2000/MS2000A series with built-in logic analyzer.
So far they only make MSO4000 and DS1000D series with built-in logic analyzers.

Is anyone going to risk the upgrade firmware on your DS2000 from DS2000A? ;)

Probably not before the DS2000A firmware has been hacked.

Since even their dealers/service personnel might mistakenly use the wrong FW file at some point, I would hope Rigol has given some thought to handling this possibility gracefully:
i.e. A-version FW won't load - OR - A-version FW is compatible - OR - A-version FW is not compatible but an older non-A version can just be boot-loaded over it...
- but perhaps I'm giving them too much credit ;)
I'd give it a try - but am in the middle of a job and can't run even the small risk of down time on the DSO right now. Perhaps in another week or so.
Meanwhile, I'll email Drieg and see if he knows the answer.
