I will try the new encoder today when I get home for the SD780.  I'll just use a program that turns on a LED to be safe.

Interesting, maybe every camera requires different numbers now.  You can find the diskboot loading code quite easily by looking for the string "not executable\n"

For ixus100_sd780:

dword_FFB1C514  DCD 5, 3, 6, 1, 2, 7, 0, 4 ; DATA XREF: ROM:off_FF99FF54 - as for SX200  :o

I'll try it again and see.  Maybe I did something dumb.

Here's a udumper encoded with the new settings.

I would be interested if it works on
- IXUS 110/SD960 http://chdk.setepontos.com/index.php/topic,3585.15.html


Unfortunately no luck so far on SD960.

I tried to create a dump of my SX20 using udumper, but it doesn't work. This are my results:

  • DryOS - Camera starts as usual and displays card locked message
  • New DryOS - Camera doesn't start, only 0's in empty.dum
  • New version by reyalp - same as with "New DryOS"

ixus200/SD980 appears to use a different value { 2,5,0,4,6,1,3,7 }

If each new model uses a different set of values, I probably need to re-think the dancingbits change.

Here's a udumper encoded with the new new new values ;)

Well I compiled my sd780 build with 53612704 and funny thing... 

It did not start up but it also did not crash my camera.  After removing the card and pressing play it would boot normally.  When I build the image with a dancing that is not 53612704 it does not boot (as I would expect) but it crashes the camera to the point where I need to remove the battery. 

Soooo my thoughts are that my build simply isn't setting some power bytes that seem important in the newer cameras.  So I'll look into that but for now I think we can say that it's kinda confirmed that these are the correct numbers for it.

Your CHDK port boots with "firm update" right ? So if you set "NEED_ENCODED_DISKBOOT=2" in your platform/<camera>/sub/<version>/makefile.inc you should get a working diskboot of your port when you "make clean fir"

Note that if you haven't got to the point of disabling the canon diskboot code, you'll get a boot loop.
