Debug mode can be succesfully enabled on Samsung GX-1S with firmware 1.02.
Unfortunately, there is no debug menu like on newer cameras.
The same procedure will probably work on all *ist and GX1 cameras.

Only the MODSET and AUTORUN extensions may differ.

 

1. Format SD card in camera (I tested 16MB and 128MB)
2. Create file MODSET.TXT in root of SD with desired testmode (only one option at time)
3. Insert SD card in camera - DON'T CLOSE SD CARD DOORS!

4. Turn On camera and wait few seconds

 

modset filename: MODSET.TXT

scripting filename: AUTORUN.375

 

Works only in [DEBUG_MODE DIS]:

[AF_PINT_DISP]

[DSP_ROM_STORE]

[CPU_ROM_STORE]

[EEPROM_STORE]

[EEPROM_LOAD]

[LENS_COMUNICATION_CHECK]

[RELEASE_AGING]

[SWITCH_TEST]

[PRODUCT_NUMBER_DISP]

 

Enable/disable scripting

[SCRIPT_EN_MODE DIS]

[SCRIPT_EN_MODE EN]

 

Enable/disable camera operation with SD card doors opened - usefull for testing:
 [CFDOOR_OPEN DIS]
[CFDOOR_OPEN EN]

 

Enable/disable debug mode

[DEBUG_MODE DIS]

[DEBUG_MODE EN]

 

 

Works only in [DEBUG_MODE EN]:

[DEBUG_DSC_DISP_OSTIME_INFO] - displays internal camera clock. [DEBUG_DSC_DISP_DSP_STATE_INFO] - dsp info, you should take a picture. [DEBUG_DSC_DISP_VENDOR_INFO] - same as DSP_STATE_INFO?

[DEBUG_DSC_DISP_BVAD_INFO]  - same as DSP_STATE_INFO?

[DEBUG_DSC_DISP_DEBUG_INFO] - some debug numbers [DEBUG_DSC_DISP_BATT_INFO] - same as DSP_STATE_INFO?

[DEBUG_DSC_DISP_BVD_INFO] - some hex-values - probably exposition. [DEBUG_DSC_DISP_LVDDASH_INFO] - some numbers like DSP_STATE_INFO .[DEBUG_DSC_DISP_LV_INFO] - looks like DISP_BVD_INFO, but different numbers .[DEBUG_DSC_DISP_STROBE_INFO] - info about flash state [DEBUG_DSC_DISP_LENS_INFO] - same as DSP_STATE_INFO?

[DEBUG_DSC_DISP_CPU_STATE_INFO] - displays mode state, af state, exposure state, temperature and sw at bottom means pressed button code.

Some information update
 
Latest Softune (with MB91680 support)

CPU definitions file have some info about MB91680 interrupts.
 
REALOS related stuff :-)
 
Last file has tools and good manuals on RealOS functions.
First one has libraries on sources of kernel functions (works with Softune).
It looks that DSLRs use RealOS, as they heavy use 0x40 and 0x41 interrupts.
In early Pentax DSLRs "Softune REALOS/FR.." string was present.
 
If you have good Japanese knowledge, contact me, please!

I really hope to get MB91680 manuals :-)

Cvetan Ivanov is joining our small team!
 
Welcome aboard, Cvetan!
I am sure you'll help us to get tail wind :-)
 
Some info from Cvetan about MODSET files for K10D/GX10 v1.20-v1.30 firmware.
 
Use MODSET.TXT and leave card door open.

AUTORUN.xxx working script
%A = 1000
WHILE %A < 1004
{
PRINT "Hex value %x" %A
%A += 1
}
PAUSE
%B = 50
PRINT "B=%d" %B
PAUSE
EXIT

 

As you can see, it uses integer variables, loop and printing of values.
