As soon as someone gets a dump of the firmware on the device of a DS2000A scope, it is very likely that the keygen will be modified to accommodate the newer model. Just take the time and read this entire thread. It will take a while, yes. You will learn many things if you don't rush it. --- End quote --- Rigol DS2072A - check FTDI JTAG thingy - check Now if anyone could get me short instructions which SW and commands i should use. Since i am not sure what exactly gets URJtag or gdb to create the dump you guys need. --- End quote --- Try to PM cybernet and ask for instructions. |

use the gdb bfin proxy from bfin uclinux when u have patched it up (see DG4000 thread, first few posts) - its the same pinout. start with something like: --- Code: ---./bfin-gdbproxy --debug bfin --frequency=6000000 --- End code --- (lower frequency might be needed, i kept it very short in terms of cablelength to get 6mhz) then use the bfin-gdb - connect to remote target (e.g. target remote localhost:2000) and u should be able to do what u want. stuff thats needed: one dump when its sitting in the bootloader (as the booted application image overwrites stuff in RAM) and one dump when its booted up - it helps if u do that dump once u entered a easy to find license key ala "AAAAAAAAAAA..." check http://www.analog.com/static/imported-files/processor_manuals/ADSP-BF52x_hwr_rev1.2.pdf page 115&116 - memory map, and dump everything thats listed there with gdb dump ... as binary. |

[...] Manual: Make sure System -> Startup is Default. Set the clock to 2099, 31 Dec, and 23:58 hour. Wait a few minutes for the clock to rollover past 00:00 (you can see it in the normal screen at the bottom right), Put the clock back to the correct date and time. Reboot Wait at least 30 minutes for warm-up, then do a self-calibration. After the scope is finished, it will reboot once. Make sure System -> Startup is Default. Then you just have to wait for awhile. The options will come back sometime when you boot up between ~3 to 60 hours later. --- End quote --- This procedure didn't worked for my DS2202_A_. However, I noticed it lost somehow its calibration when the date rolled over. But the trial licences are not reset. So maybe I made a fault? However, it would be nice, if a non-A-owner will remove his keys and try this procedure with the newest firmware (which is for both scopes, "a" and "non-a") to check if it still works. Because smashing the trial minutes only to check that the trick will not work for "a"-scopes is a waste... |

Also, have you waited ~3 days? --- Quote from: tirulerbach on December 19, 2013, 06:32:24 pm ---Because smashing the trial minutes only to check that the trick will not work for "a"-scopes is a waste... --- End quote --- It would be silly to do it at all until the trial minutes are finished - and you want more trial minutes. Then nothing is lost/wasted either way. |
