oliv3r:
Very interesting, with an A40i, it must be running Linux.

Funny how they jump from supplier to supplier (rockchip for the new DSO etc). I bet software engineering effort is 'free' right? :) having a software platform would help a lot.

But WHY this horrible keypad? Why not the standard 3x3 layout? Am I missing something that is 'normal and common' in EE circles?

Next, we need some firmware dumps so we can hack it!

coromonadalix:
loll  i hate this kind of keypad, i have the impression of using an old  "wheel dial" telephone  loll

Seems well built

KrzysztofB:
After using it for a while I can tall you, circular layout is least annoying part of user interface.
The same goes for DG2102 generator.
Hardware wise devices feel ok, but UI... dear lord, I'm trying hard, but it's so non intuitive that just hurts my brain.

hve:
There is some firmware available:
https://www.rigol.eu/Public/Uploads/uploadfile/files/20230321/20230321002306_6418886a99c29.zip

Its a rar archive, extract using:


--- Code: ---unrar x 20230321002306_6418886a99c29.zip
--- End code ---

then there's a GEL file, extract using:


--- Code: ---tar xvf DP900_DP2000_Update.GEL

-rw-r--r-- adil/root       108 2023-02-08 13:52 checksum.txt

--- End code ---

then there's a cpio archive:


--- Code: ---cpio -i <tina-r40-m2ultra.swu

-rw-r--r-- 1 henk henk 14680064 Apr 12 22:04 rootfs


--- End code ---

Then there's a squashfs filesystem:


--- Code: ---file rootfs
rootfs: Squashfs filesystem, little endian, version 4.0, xz compressed, 14674551 bytes, 1446 inodes, blocksize: 262144 bytes, created: Wed Feb  8 12:49:37 2023
--- End code ---

So we have a sunix linux system running on your PSU unit together with an FPGA.

hve:
Could not help myself:


--- Code: ---unsquashfs -l rootfs > lst.h
--- End code ---
