Could you also try with TTsource and the files I posted?

OK!  So, this TTsource program.  It's pretty terrible.  I can't get it to allow me to load data of any kind under any circumstance.  The program is talking to the generator as I can set the frequency.  But that's it.  Any clues to help?

http://rdg.cc/files/hantek/hdg2002B-1.0.1.1.tar.gz

By the way, I didn't remove my serial from the system.inf, it was set to 'undefined' from the factory.

i just restored it on my dev board, it looks really like early dev version. Not only debug infos available, but as well still some undefined things (like your SN or lib version or executable build date/version). One can use all that information to understand all the executables and libs much better, most function names from current firmware can be restored now using your dump. Thx!

Would you be interested in my v1.0.0.1 or do you prefer to wait for someone to post a v1.0.0.2?

Sure, if you could post your version I could try it out. Still no response from Hantek. Thanks!

there is a lot of file which need to be then updated, i've created html report (based on your and fremen67 dumps).

I'm wondering how they loading the /lib/firmware/htg1000.bit on your unit, sure, it might work via lib as well,
but on current hardware there is extra executable (/dso/cfg_fpga) started from /etc/init.d/rcS/ to load the /lib/firmware/htg1000.bit. What even more interessting, there is no CAL data on your unit.

Note: i named your fw HTG-1.00.1(131107.0) , because this is the /afg_bin time stamp

Note: in report, red - different binary, blue - missing on the other side.

Yes, this is not very intuitive.
First you have to synchronize TTsource with the HDG: Initial->Real Time->Read Operation
You select "Arb" function and then you import the .hwf file: File->Import Data (The import menu won't be active until you select Arb function)
The parameters of the imported file may not be correctly displayed: only samples and divider will be correct, frequency may not. For example the imported 10Mhz Sine file will show as beeing 1000 Hertz ...
Then you click on the Write button and eventually enable the channel if not already... that's it!

Well done! Did you use IDA Pro?
