DG4000 - a firmware investigation

[TooOldForThis]

I tried this "Piranha(DSP)Update_00.01.09.zip" update without luck.

EV,
   You have to rename the file to  "DG4000Update.GEL"   The bootloader only looks for "DG4000Update.GEL" on the USB stick.

The new bootloader loaded in a few minutes.  The new application file took at least 10 minutes to load.  For both files, the DG4000 rebooted  itself after it was done loading the new GEL file.  Don't chicken out part way through the load process.

The problem is that I can not load the new bootloader. I tried it again and waited 15 minutes but no luck. Only Mod, Utility and Store buttons are lit. Nothing else happens.

The USB stick is 1 Gb Kingston and it works with the generator.

Here is the system information now:

Software 00.01.08
FPGA 00.01.09
Hardware 01.01
Keyboard 04.01

Did you rename the DG4000Update_Bootloader.GEL to DG4000Update.GEL?

Did you rename the DG4000Update_Bootloader.GEL to DG4000Update.GEL?

Thanks PA0PBZ!
I did not realise that also the bootloader file had to be renamed. 

The system information is now:

Software 00.01.09
FPGA 00.01.09
Hardware 01.01
Keyboard 06.01

Don't worry, I only got the idea after reading your post for the third time

Is the calibration still OK after the 1.09 upgrade?
If the calibration is back to defaults, your amplitude and offsets are way out.


I'm asking because if you upgrade the firmware on a DG1022, your calibration is lost, and loads factory defaults. I had this with my DG1022.

Just be aware that upgrading software on RIGOL generators it might loose your calibration!

If the calibration will be lost, I have lost it already two times before this update. This was third FW update for my DG4162. There is only manual calbration which is behind password.

http://bayfiles.net/file/1lrDi/0Wrw06/bfin_rigol_cybernet.rar (for IDA 6.1)

bfin module is (c) Andreas Schuler, rigol ldr contains some of my mods to also read GEL files right away.
PM me if u need the IDA DB with my initial reversing of the .GEN files.

maybe its worth checking new vs old bootloader to prevent rigol from preventing u to downgrade.
the old BL is fully reversed if somebody has questions about it.

unfortunately not much time for rigol stuff lately, but i see its in good hands ;-)

Click the Premium Download button...

[cybernet]

i would expect that ppl who can make use of my shared files are able to download them without infecting their computer with adware - if not, then i suppose it acts as a gatekeeper ;-)

[PA0PBZ]

Therefore my personal opinion is that this isn't necessarily a favorable file download service for us to use.

Ted,
I totally agree with you, I just hate these sites tricking you into clicking something that you wouldn't if you knew, like this example or the ones with download buttons all over the place giving you a hard time to find the correct one, or those like a maze just telling you that the file is gone after you have been served ads for like 5 minutes.
But then again, there's something about the given horse etc... so if cybernet decided to use that site I'll thankfully download the file and curse silently

I did PM but:

pm deactivated, use the search function ...

So not sure if it ever got there.
I'm interested in what you have, because I can always reinvent the wheel if I ever have enough time...

Thanks! And while you are at it, the IDA rigol loader file you uploaded is a .obj, not a .ldw

Got it, thanks!

Hi,

I have read most of the thread and it appears that the latest 4062 is no longer hackable (as apparently it comes with a version of the firmware that can't be hacked yet.)

Is this still true?  Is there perhaps a more complicated route, but still hack 4062 to go up to ~200Mhz?  I was planning to purchase a 4062 and this is a key factor to consider.

Thanks.

Hi Cyber,

If you have an IDA file for the old BL I'd be more than happy to have a look. The new FW is a dead end, they removed the part that reads the license file and I'm not feeling like putting that back in. So the best route to take is to convince the new BL to accept older FW, but even disassembled the BF code is hard to read. So if I can understand the old one I could probably make something up to fool the new one.

[cybernet]

see pm dont want to give rigol ideas

[fact]

Cyber,

My DG4062 also suffers from a too recent firmware to hack and I'd like to take a peek at your investigations regarding the previous version of the bootloader. Wonder if you could spare me a copy of your work.

[fact]

Any progress yet?

Hi, any one know, that dg4100 with:
Software 00.01.07
Hardware 01.03
It can be hacked?

Thanks, Robert

Hi, any progress made on this?  Thanks.

Well, just ordered a DG4062 from Tequipment today.  Hoping the ones in stock have a 01.08 or lower.  If not, I think 60Mhz will satisfy what I need.
