Problem with Powershot A490

Hi all, I have a problem with a powershot 490. I installed CHDK on my camera (A490-100d). When shooting photos using various scripts, the photo is not saved because the camera is turned off during the save. No script worked. How can I fix? I was looking for a script to handle the shutter. Thanks in advance

First, make sure you are using the correct CHDK version for your camera (is it 1.00d?).
If it's correct, then make a romlog and upload it here.
CHDK menu -> Miscellaneous stuff -> Debug parameters -> Save ROM crash log
Maybe someone else has a better idea about what could be wrong.

Do you have RAW enabled ?

Hello, yes, I checked via camera version and I get 100 d. Now I copy the romlog

Yes, raw is active, and sometimes be saved but at a poor resolution. But the jpeg is not saved and the camera turns off when saving.

Maybe the bug is here:
Code: [Select]
"MOV R5, R0 \n"                           
"BL     capt_seq_hook_raw_here\n" // +"BL sub_FFC5BFCC \n"                     
"BL sub_FFC5C014 \n"                     
A modified version attached.

EDIT
File deleted, patch submitted

Ok, I downloaded it and it works. I put it in auto mode and some script work. Thanks for correcting the bug.  : :)
