Is this the JTAG that would work? I just got my 2072A and would just love to open it and play

Yes, that's the one.  In the JTAG connection diagram posted a little while back I used the second setup (pull-ups on TRST and SRST lines -- don't connect these to the programmer at all), but either way should work for you.

Good luck!

Excellent! I'm going to pick one up as well. (2-4 week delivery time sucks)

I assume I should restore factory firmware before doing the dump?

short question, didn't follow the thread for a while: why do you need to downgrade? Don't the keys work for V. 01.08.00 anymore?
Kind regards

Hi,

Got my DSA 815-TG yesterday :)

I'm very happy with it, I upgrade it to the latest firmware version without problem and apply the options with the magic keygen without problems, now I leave it on to "clean" the trial versions, I suppose they will expire and disappear, it will be verified tomorrow.

First make an upgrade, then make the dump...

I might take a dump before or after the upgrade, just depends on the time of day.
But if you want to know if you should dump before or after, I would say during - get it started then go take a dump.

Hey All,

I am ready to pull the trigger on a DS2102A. Has anyone confirmed that the innards of the 2072A to the 2202A are identical? Would I be able to view 200MHz signals without issue with the 2102A - assuming the appropriate "patches" have been applied? I would be more than willing to dump the memory to help the cause.


Cheers!
