Perhaps you mean DG4062 with v01.10?  There is no v01.12 for DG4000 series yet.

Glad you got it

Yeah, I got a license OFFICIAL for my MSO1074z  ;) !

I used Olimex adapter https://www.olimex.com/Products/ARM/JTAG/ARM-USB-TINY/ , but it is not connected to the scope port :( I do not know why, probably there is a problem with the drivers Windows 7 and Linux (Ubuntu x64).

I asked at the local forum another adapter from a friend. It was a cheap Chinese Segger J-link adapter for $ 20 :)
Next I used https://www.segger.com/jlink-software.html?step=1&file=JLink_496d to communicate with the "segger" adapter.



To dump commands are used Halt "h" and "savebin" commands. I also increased the speed of the bus to 6MHz ("speed 6000" command). The 64 MB memory dump copied 8 minutes.

Then I used rigup 0.4.1 under Debian Linux i386, but I changed the Makefile "LDFLAGS: = -O2 -Wl, - gc-sections c" as written here on the forum.

Rigup generated correct keys for my scope :)

Thank you  ALL !!!

Here's part of the source code in riglol.c (source code can be downloaded at the bottom of http://riglol.3owl.com)

I don't know who wrote/maintains this code, but I found a small bug that I want to report.
There is a line which may or may not function as desired depending on the compiler.
Here is my simple fix:
