Curious why the DP831 power supply wasn't worked on here.  Are the keys actually implemented differently?
Twingy:
Downloaded the 64MB image from MSO1074Z using Olimex JTAG USB-OCD-H.  Generated the license file using rigup scan, serial number is correct from JTAG image, other licenses including tea key look valid.  Attempted to generate a triggers key (CSAR=0x1C001) with from license file using rigup license.  Invalid license! for the generated key.  Tried 0x1C002, invalid license as well.  Tried the updated rigup source from loaderr and generates the same keys, nothing different.  Firmware is 00.04.03.SP2 BOARD 2.1.4.  Any help is appreciated.
Twingy:
Another short update.  I changed the adapter_khz from 400 khz to 3000 (3 MHz) but the transfer speed off the mso1074 still appears to be limited to 25kB/sec, for ~45 min transfer period.  I performed all of the same steps using this new .bin image file and get same results, so I'm fairly certain the bin file is valid.

Additional Notes: On my mso1074z the jtag male header is missing.  Rather than try to solder on the header by removing the board/voiding the warranty etc, I used a male header and light force so as to avoid modifying the hardware in any way.  I also use rubber gloves to avoid getting finger prints all over the internals.

For the 831 you just generate keys for 832, put your serial and go.. Worked fine on mine 831... I also made changes on one of the member DP832 python calibration script to work with DP831 and DM3068..

Sweet.  Good to know.  I didn't see that actually stated anywhere before.  Thanks!
