Sniffing the Rigol's internal I2C bus

Keeping trying to update.  I had it not work, blink for just a few seconds then go solid on, but stay on the old version.  I kept at it and finally it blinked for 3-4 minutes or so and worked.

alank2:
cybernet do you still have the CH1 200M bandwidth limit?  I can get to the 1ns timebase, but no 200M...

The bit in DSBA was accepted by the older firmware too, it would be nice to figure out what it does.  I find it interesting that they stepped around this bit, so there must be some significance to it.

I have a DS2072 hardware 1 and can't do the update to http://www.filedropper.com/ds2302rilol and therefore no CAN.
The update procedures seems to run like it should, and then, when the scope reboots, everything is just like before. The software version did not move from 01.01.00.00.02.
I have a DS2A0000000001 serial, could that be an issue?

Did you rename the DS2302_RILOL.GEL file to DS2000Update.GEL first? That's the only way you can load it.

But there seems to be no reason to install this custom firmware anymore after Cybernet's latest posts here with new key options for 300 MHz, CAN etc..
Just download the official firmware 00.02.01.00.03 uploaded here instead.
Then un-rar DS2000Update.GEL and load it.
After updating apply a key generated with DSAR DSHH to enable all options.

iNoxxam:
Thanks,
I finally managed to get all the options by:
- Updating to 02.01 with the official .GEL (several times, to get it working)
- Installing the key generated with DSAR
- Installing the key generated with DSEA (for CAN)
- Installing the key generated with DSCA (for 300MHz)

My S/N is still DS2A0000000001 though. If someone finds out how to fix it I'll be interested into that.

It is now full option thanks to you... Thanks a lot!

--- Code: ---0x1C080    - DSEA - PROTOCOL ANALYSIS - CAN
0x1C040    - DSCA - BANDWIDTH - 300M Bandwidth (takes a reboot to show up in System Info)
0x1C020    - DSBA - (installs option, but i dont see it ?)
0x1C010    - DSAS - BANDWIDTH - 200M Bandwidth
<known codes still work - see elsewhere>

enable 0x1C0E7 -> all but 100/200M bandwidth-> DSHH
--- End code ---

i wonder if 0x1C020 is the 50Ohm option, which my hw probably doesnt support.

UPDATE: despite being DS2302 model, bw limit option is only NONE,20M,100M - somebody better confirm that NONE = 300M ;-)

Are LIN and USB protocol analyzers enabled too like mentioned below? Or maybe they aren't actully implemented in the firmware yet, but they have just reserved key options for it?.

--- 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??
