Better dumper, should work on FFC00000 or FF810000 cams (note, only FF810000 tested)
Code: [Select]
dim f,a,v,startadr=0,romsize

private sub Initialize()
UI.CreatePublic()
a=LCDMsg_Create()
LCDMsg_SetStr(a,"Running")
System.Create()

if memcmp(0xFFC00004,"gaonisoy",8) = 0 then
startadr = 0xFFC00000
LCDMsg_SetStr(a,"FFC00000")
else
if memcmp(0xFF810004,"gaonisoy",8) = 0 then
startadr = 0xFF810000
LCDMsg_SetStr(a,"FF810000")
else
LCDMsg_SetStr(a,"start not found!")
Wait(1000)
end if
end if

if startadr <> 0 then
romsize = 0xFFFFFFFC - startadr
f=Fopen_Fut("A/PRIMARY.BIN","w")
Fwrite_Fut(startadr,romsize,1,f)
Fclose_Fut(f)
LCDMsg_SetStr(a,"done")
end if
end sub
We've really been doing this **** the hard way, lol  :o

edit:
reversed address checks, since FF810000 might not be in ROM on an FFC00000 cam.

The hello world code in the pdf doesn't seem to work though.
After I started the camera with play button and pressed SET button, nothing happened. If I keep pressing the SET, it starts to display a clock.
I used WinHex to verify the SCRIPT signature and it's there.

you have "for DC_scriptdisk" in script.req ?

You are sure the SCRIPT string is at offset 496 ?

You should only have to click set, and the message shows up in the upper left, in black. If you have no pictures (or that corner of the pic you are viewing is black) you might not see it.

edit:
Of course, it's possible canon closed this off too :)

Yes. I tried it with and without EOL.

The string is at 0x1F0 so it should be offset 496.

The dumper doesn't work either...
I don't think they removed the interpreter from the OS. Probably just changed the way to activate it.

edit: or it may be that I was doing it wrong.... wait for someone else to confirm this

Do you have an older camera you can try it on, to make sure the disk is prepared correctly ?

BTW, the disk probably has to be FAT16

Unfortunately no...
But is it possible that you make a disk image?

Oh my card is FAT32 and its size is 8GB.

You should be able to make a single FAT16 partition on it, but first let me check whether this is actually required.

edit:
Nope, seems to work fine on FAT32.

I can't get it working on an IXUS 130 (SD 1400IS) either. Shame, it would have been very nice...

Great news guys! I use first reyalp's dump script on A3100 and it works! But start adress is not 0xFFC00000, it's 0xFF810000
Here this dump (24 969 204 bytes, A3100 ver. 1.00B P-ID: 31F1):
DUMP_FF810000_A3100_1.00B.BIN - 23.81MB

upd: I tried to light LED's on sx210 with this simple script:
Code: [Select]
dim f,b

private sub Initialize()
System.Create()
Driver.Create()
for b=0 to 10
LEDDrive ( b , 0 )
next
end sub

private sub Terminate()
end subbut it doesn't want to start on sx210 (it works on other cameras) :(

Can someone try to run this on sd1400/sd1300/sd3500/sd4000. If it works - there the problem in camera, if not, I suppose that Canon made some "fixes" to script running system.
