It worked perfectly!!!

now i need to learn how to do it myself so i don't have to ask everytime a new version comes out  :)

Thank you so much to everyone for making such a wonderful software!   your all great.

(or can the patch - by bernd R (Thanks again) -  that i have been able to succesfully test be added to the main CHDK build?


Have you tried loading some scripts with it? For me, the Intervalometer script doesnt work.

So that means we are back to the drawing board since it is worst now than before because it would only crash the camera on startup and now it crash when loading a script.

i agree wowsers....the scripts should work for sure!

i wonder why a command to wait for an extra second on startup would affect the script ability though?

hopefully our programmers will be checkin the thread soon :)

I took a look at the code for the SX20 firmware 1.02d and looked at the firmware dump.

I think you might have a problem in boot.c when setting up the links to the taskHook function.
The address 0x1934 does not appear anywhere in the firmware that I can see; but both 0x1938 and 0x193C do. In the SX30 port I had to set 0x1938 and 0x193C to point to the taskHook function to get it to work correctly.
Perhaps the task initialisation is not being done properly.

The 0x1938 hook appears to be used when you start in record mode (by holding down the power button for ~1.5 secs). On the SX30 I had to add the 0x193C hook so that when starting in playback mode it starts up correctly (when you do a quick press of the power button).

Take a look at the current SX30 boot.c code to see how I have done it.

Hope this helps,
Phil.

unfortunatly i am not a programmer and don't know what i am looking at....sorry

also, i downloaded chdk shell - and it doesn't have the sx20 listed in the latest trunk.  why is that?

edit - the sx20 shows in trunk 1050 using chdk shell, but not in 1066 or 67
same with sx30 (just noticing, even though i don't have that camera)

I can try and make the change I think is needed and build a test version if you want to test it (I can email it to the address in your profile). I'll need to know what firmware version you have.

I don't use this so I don't know what is wrong. I do recall reading a post recently about something being broken in the makefile.
