Sniffing the Rigol's internal I2C bus
Neuro:
Yesterday I succesfully hacked my Rigol MSO1074Z.
Thanks to the modification of the procedure now there is no need to use two OS (Windows and Linux).
Debugger, that was used, is Jet-Link Pro.
Details are here:

yes, if anyone knows if one can downgrade the bootlader via JTAG.. I have a DG4062 with the same problem..

My dsa-815tg came with FW 01.09.
Model : DSA815Serial Number : DSA8A144xxxx
Version of Main Board : 00.04
Version of Radio Frequency Board FPGA : 00.05
Version of Digital Board FPGA : 00.04
Version of Firmware : 00.01.09
Version of Boot : 00.01.02
I tried to downgrade to FW 00.01.08.03 and then install all keys...all keys accepted.
then back to 00.01.09 and all keys dissapear!
installing official key for TG restores normal operation.
Is there any other way to upgrade and keep the keys??? It's strange because I have boot 00.01.02.
Did I do something wrong???Maybe trying to downgrade to 01.06 and repeat all???
please info..tnx

Just tried to dowgrade DSA-815TG from present 01.08. to 01.06 and all licenses still active....then upgrade to newest 01.14 and all options dissapear again! BOOT 01.02 AND LICENSES DISSAPEAR WITH UPGRADE FW TO 01.09 OR HIGHER!
Downgraded to 01.08 and install all licenses again.
Stucked with FW01.08 for now :( .
agronaught:
So am I right in what I've read that one of the 'new' dsa-815's will lose the presumably unpurchasable 10Hz RBW bandwidth when the trial timers expire ?
I just took delivery of a new unit and I'm not all that keen on opening it up immediately. If the 10Hz RBW breaks than I see no alternative but to bridge the pins on the fram.

TheSteve:
New units don't have 10 Hz RBW anyway. While the option exists it isn't official and doesn't exist according to Rigol. Unless your unit is special 100 Hz will be the minimum RBW.
