Try to upgrade to publically available v1.10 version.
It is updated to that version (downloaded the upgrade and did it on last week).
Has anybody had success on K-m? I don't really have time to try 999 versions of MODSET.XXX ...

Please, look carefully on method proposed by K200D owner. He used bat file to make all files and copy them at once. So, only one check is needed.

Disassembling progress
I also have good news as it looks like we will be able to use legal IDA 4.9 Freeware for research. I managed to make Fujitsu processor module that sucessfully runs with free IDA version. It was considered impossible without touching IDA (and this is illegal, as we know). But I won't distribute it on my site until we will be able to write such module from scratch to be absolutely clear here :-) It is quite poor at the moment. But if anyone want to participate in disassembling you can PM me (I'll ask few questions first).
Try to use IDA Free 4.9 first with Windows executables (like Camera_Control_V2.dll), as it is about 20x time easear :-).
Remember to find modern signatures for IDA. And try to read some books, af far as I know best one - Amazon.com: The IDA Pro Book: The Unofficial Guide to the World's Most Popular Disassembler (9781593271787): Chris Eagle: Books.


As for C/C++ guys - we need two things :
1) Make refactoring of existing DFR disassembler we have on my site. COde is not that bad, but quite a mess.
2) Modify interface and add it to Biew (and, later, possibly Neo Hex Ultimate).
3) Make software to find fonts and bitmaps.

Om not yet certain of this, but i feel like i should write it down somewhere.
Looks like enabling debug and scripting, even after i've disabled them, disabled guide display (showing shooting mode when changing them or powering on on main LCD).
I could enable it in menu, but i left it disabled.

If you look at last assembler strings on my screenshot you could see:

QuoteQuote:
ldi:32 #Get_File_Extension, r12
call @r12
This is typical FR far function call.
Unfortunately current FR module can't move analisis to this address and don't add proper xref.
If anyone here know C quite well and is not afraid to work with command-line BC++ compiler (you can download one free from Embarcadero site, btw), you are welcome.
Of course, it'll require you to learn some IDA functions :-)

Autorun present and executed : Guide display self turn off in setup menu.
Removing autorun or disabling it in debug menu allow you to set guide menu back on.

You can find here a zip file with all possible file names to enter into debug menu.

Be sure to use FAT32 on your SD card (FAT16 allow only 512 files on root).

Once in debug menu use 'DSP ROM SAVE to FILE' .
On SD card root you now have a KBxxxDSP.BIN with xxx the right number for your firmware.

I've tried it with my K200D (first with Polish language set, then with English), but nothing more than displaying VER: 1.00 happened. I saw no debug menu at all.

Steps I took:
1) format SD card with FAT32 filesystem
2) unzip provided file to the root directory of SD card
3) turn on K200D with MENU button pressed

Does anybody reported similar impossibility to enter debug menu in K200D?

Look at earlear posts in this thread.
MEMSET works on K200D with v1.00.00.03 firmware, as I have dumps of this firmware done using MODSET.445.
If you have AUTORUN.445 in same card, MODSET won't work.


BTW. We managed to get help from a guy who did similar project in private with
K100D. He also made some improvements to FR module. I'll check it and make new working module soon.

Progress report

I managed to make new FR module using source provided by one very expirienced guy. :-) Now it can analize such jump as described above.
And also add xrefs. Can also make some local variables.

He also provided some very useful information for dumping additional debug information.

This is how it looks now.

Special request

If you have already enabled DEBUG MODE.
Please make SYSPARAM.TXT file on SD card root.
Put [STOREAE] 1@ inside.
Send me resulting dump file, please.
The more guys will send files, the better.

Привет всем,

I haven't been following this thread for a few days and now I am simply amazed looking at the progress, you guys have made here!

Tomorrow morning I will need to spend some time thoroughly reading all this thread.

I am C++ developer, no embedded device programming experience though and assembler programming days are over for me many many years ago. Anyway, currently I am not too busy, so I could try to help for this project...
