Sniffing the Rigol's internal I2C bus
elscode:
I have got the brand new version of dsa815. Downgrade to previous firmware version is not possible. Image is considered as invalid and upgrade process aborted :-//
radiogeek97:
if this is actually the case what is the last version of the FW where the "upgrades" will work? The other question i have and i am a total newbie: If i got an 815 with the latest "locked" FW how would that work with the old software licenses for accessories ect, for example the rigol SWR brige kit comes with the hardware and a software key for $600 usd if rigol eliminated the "home upgrade" process by another FW revision wouldnt they have to change all the old legacy software license keys? IF not wouldnt the same KEYGEN software work? what if i got a brand new up to date dsa815 from rigol and bought a new rigol VSWR bridge/and software license off ebay would the old software license be incompattible? JUst a few random newbie thoughts

It seems that all the messing around with holo-stickers and JTAG may no longer be necessary...
Check out this thread https://www.eevblog.com/forum/testgear/rigol-mso2000-series-hacking/180/ where PeDre has shown that a memory dump can be done using a simple SCPI command over the USB or LAN ports using a free download utility. That memory dump can then be applied to Rigup in the usual way. This has been successfully done by at least 3 people so far.

Has anybody purchased a rigol dsa815 with the latest FW and have been Abel to use the rigol key gen utility to upgrade their device successfully ?

As myself and another stated on page 236, no, it does not work.
