Sniffing the Rigol's internal I2C bus

<< < (780/899) > >>

H.O:
I agree, why is there a need for a PC software key when you must have a scope with the PA option enabled connected to the PC in order to actually use the software?

Anyway, have you tried generating a key (for the PC) with somethig like AAJA or BAJA?

I'm getting ready to do the U1105 Pin 7&8 hack on my DSA815-TG and while it's open I'd like to dump memory to look at things like has the serial changed? or would the same hacks that got the MSO1000's going work on the DSA815 with the 1.04 boot loader

Does anyone know which JTAG header I need to plug into and what I need to dump memory wise?

You do not have to do a memory dump to see the current Serial Number.  Simply go to DSA System Info and compare the S/N here to the Rear Panel S/N Label.  They should be the same.
JTAG Connections:  Once you remove the DSA815's Rear Plastic Cover you will see the two connectors.  You will NOT have to remove the metal shield, just the rear plastic cover!  The upper connector is the 8 Pin 'SPI' Interface for VREF, and the lower connector is the 14 Pin (Blackfin) 'JTAG' Interface.
Do NOT connect Pin 7 (3.3 VDC) of the 'SPI' (8 Pin) Connector to Pin 1 of the (14 Pin) 'JTAG' connector.  It won't hurt anything, except the DSA815 will not initialize and Power up.
Reference this -> https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg522376/#msg522376  for the Pin-out details.
Note: You may be able to use this application here ->  http://peter.dreisiebner.at/rigol-bildschirmkopie-lan/  without needing to go to the trouble of doing a JTAG Memory Dump.

I meant Private Key not serial number, sorry about that.

Thanks for the rest.  not sure how I missed the JTAG Header info in that thread
I think I also saw the range to dump in it and that it could be dump via SCPI

Were you ever able to dump the memory via JTAG?

SCPI READ seems to not be implemented on my DSA815, or I am doing something wrong.
