The romlog is always the same except for date. Crash only occurs if sync enabled.
Upside camera blanks screen and waits for switch release,does not crash.Pointing at mirror, crashes nearly every time except when I cover face with a glove !
It is definitely face detection.
Maybe waiting for switch release interrupts face detection at a critical phase ?
So the most obvious conclusion is that an upside down camera does not recognize faces?
If you point the cameras such that there are no faces in the field of view do they ever crash when shooting?
Adding a "yield" to the sync hard coded loop might cause the problem to go away, at the expense of "sync" precision.
All this also leaves one wondering why the face detection is crashing if you have in fact disabled it in the Canon menus?
QuoteAdding a "yield" to the sync hard coded loop might cause the problem to go away, at the expense of "sync" precision.Well, it would prove the theory but not really a solution.
Maybe switch-release detection should be done at the last possible moment ?
One possability, based on srsa_4c's most recent post, would be to drop the priority of the CaptSeqTask by one, to let the face tracking interrupt if necessary. This would likely impact sync quality but much less than crashing affects sync quality There could also be other nasty side effects.
The remote hook appears to be in an unusual place to me in this port (directly in capt_seq, rather than later in the called functions), so perhaps that's related.
Well,well, a search for "chdk chaseframe" finds some interesting hits :-
I wonder how many other cameras have this problem ? I will ask some friends to test.
New user here, excited to try ptp with multiple cameras.I tested two G1x (101a and 100e) with usb switch in sync mode and found it was not very reliable, crashing fairly often.The romlog file is attached.I am surprised that no one has reported this problem.Do you know if there is any way of fixing it ?Thanks.
