Dumping PowerShot D10?
« on: 28 / April / 2009, 18:34:57 »

I have a brand new D10. I tried to dump firmware using udumper, but it doesn't work (the camera won't do anything... as it should) but when I power off the device, I find that the empty.dum remains... empty :-(

Any ideas?

Have you tried cardtricks with the "NewDryOS" button option?

Also can you post the three screens output from using the ver.req file

I tried NewDryOS and DryOS... [manually, because I don't have Windows... I've read the source, and unzipped the files] also tried some other files found on this forum, without success.

I'll be glad to try to blink the leds [I have some knowledge in electronics and programming], but I cannot find the source of the blinker.

By the way, I find it difficult to find any ressource for this project... why not add all the published sources to the svn?

Hi Guys
In the SX200is we are having the same kind of problems.  More people there and I suspect the OS is the same...  Come join us in the SX200is discussions, as I think we are working towards the same NEW release of Canon's DIXIG4 OS...

I managed to blink the D10 firmware out starting at 0xFF810000. I used the blinker java version provided by syrius for the SD1200 IS: http://chdk.setepontos.com/index.php/topic,3547.msg39712.html#msg39712

Followed the instructions in README.TXT and also i made the following changes:

changed to the P-ID of the D10:

Code: [Select]
header change your key here (31BC is for D10)
HDR 0x000031BC 0x02230000 0x01000000 0x00000000 0x00000001

only made two changes:

Code: [Select]
#define DELAY_COUNT  1265
couldn't blink it any faster than 1200bps. Maybe it's the diode i got from an old mouse. you can try faster speeds. this took about 12hours to blink.
Change the start of rom addess to the on of the D10:

Code: [Select]
unsigned int startOfRom  = 0xFF810000;
Use this one instead:

Code: [Select]
@rem you have to edit the line that says @copy ps.fi2 g:\.
@rem change g:\. to the drive letter of your SD-Card
@rem you also have to edit the setvariables.bat
@rem also, you need to edit my.map in fi2envdec folder
@call setvariables.bat
@del *.o
@del main
@arm-elf-gcc -fno-builtin -O2 -Ilib -nostdinc -c entry.s
@arm-elf-gcc -fno-builtin -O2 -Ilib -c lib/crc16.c
@arm-elf-gcc -fno-builtin -O1 -Ilib -c main.c
@arm-elf-gcc -fno-builtin -O2 -Ilib -nostdlib -Wl,-N,-Ttext,1900,-Map,main.map -o main.exec entry.o main.o crc16.o -lc -lgcc
@arm-elf-objcopy -O binary main.exec main
@arm-elf-objdump -d main.exec > main.dump
@zero | dd bs=1k count=100 >>main
@copy main fi2envdec\diskboot.bin
@cd fi2envdec
@call pack.bat
@rem copy firmware upload file to SD-Card (change g: to your drive letter!!!)
@copy ps.fi2 g:\.
@cd ..

also edit fw/SetVariables.bat to your own scenario.

I did it using an old diode i got from an antique mouse which i taped directly to the AF LED; i also covered it with a piece of tin foil, which seemed to help better the poor reception. I used a 10kohm resistor; all mounted to a serial port (schematic included in the sirius' package). As i said, i couldn't blink any faster than 1200bps. The java program works well and the first minute of blinking is very good to check the acuracy of the capture: all the lines that appear should be exactly alike.
I hope anyone will pick this up and start the port, as i'm not a great programmer.

Download the firmware here:

Hello & welcome, elxarro !

I managed to blink the D10 firmware out...
Great !

I added your dump to the CHDKdumps2 repository... http://chdk.setepontos.com/index.php/topic,288.msg41607.html#msg41607
