Hi, i using firmware a810-100e-1.3.0-3451-full, PropertyCase for my camera is propset5, so "8" is:

Code: [Select]

AiAF Mode (1=Flexizone, 2=FaceAIAF or Tracking AF)
I alway got "crash"(shut down) at "shoot_half" after "set_prop(8,1)"

Here is my code:

Code: [Select]

--[[
@title Change AiAF Mode
--]]

sleep(500)
af = get_prop(8)
if af ~= 1 then set_prop(8,1) end

press("shoot_half") --alway crash here
repeat sleep(50) until get_shooting() == true

How to resolve this problem?

Thanks.

P/s: I had tested in Stable 1.2.0

I tried this on my same generation a3400 (in P mode), it is working for me. AF mode changes and I get no crash on (half)shoot.
Can you make a romlog ("miscellaneous stuff" -> "debug parameters" -> "save rom crash log") and attach it here?

That's ugly. Memory belonging to the Canon firmware gets corrupted somehow.
Can you reproduce the crash when:
- you change the AF setting in the Canon menu by hand and run a script (without set_prop, just half-shoot)
- you change a different property with set_prop (choose something safe, like compression or image size) within your script

Here's what you require, it's working fine on my camera, no crash:

Code: [Select]

--[[
@title Flash off
--]]
sleep(500)
af = get_prop(143)
if af ~= 2 then set_prop(143,2) end

press("shoot_half") 
repeat sleep(50) until get_shooting() == true

Code: [Select]

--[[
@title shoot_half only
--]]
press("shoot_half")
repeat sleep(50) until get_shooting() == true

Only crash after set_prop(8,1).

set_prop(8,2) is fine, no crash but like what i'm seeing, it's still in center mode(1) not FaceAIAF or Tracking AF(2)

Some things you could try:
1) Try compiling CHDK for yourself. If you're using Windows, there's a GUI utility to make that easy: http://chdk.setepontos.com/index.php?topic=845.0 Changing the compiler (GCC) version may make a difference.
2) You can try calling event procedures to set that property (enable native calls in the misc menu):

Code: [Select]

call_event_proc("SS.Create") -- this is only needed once per session
call_event_proc("PT_SetPropertyCaseInt",8,1,4) -- 8=propcase, 1=value, 4=value size in bytes

3) If neither of the above helps, an attempt could be made to make a CHDK build for the camera which doesn't use exmem - if the available RAM is too small, perhaps it could be made a bit larger by reducing the UI memory allocation size (that requires a small camera-specific CHDK modification) + enabling ARAM.

All suggestions above are workarounds: the crash you're experiencing should not be happening.

I borrow another A810, insert same sdcard, run script and it's working FINE

Is that my camera error? Do you have any suggest about this? Should I return my camera?

First check very carefully whether any canon firmware settings are different.
