My camera freezes almost every time when I use ND filter.
This is somewhat unusual as the ND filter position is simply set on all cameras by poking a value into the correct propset value. Seems somewhat unusual that the sx240 would work differently.
First I thought that was RAM problem, but I turned off every special or advanced options in CHDK's and original cameras menu, but no changes.
That doesn't really free up any RAM but it was a good idea.
Tried to reinstall the CHDK, but the same result. And CHDK firmware version, that I use, is compatible to my camera firmware.
So tell us a bit more about what you were doing? Are you trying to control the ND filter with a script or from the CHDK menu? Does it hang if you set it to In and to Out ? When you say hang, does that mean the camera shuts down after a while or just locks up a sits there. If it shuts down (crashes) then a ROM crash log from the CHDK Debug menu might give us some clues if you post it here.
Update: is your problem related to your other post @
