New issue 32 by kay...@gmail.com: Camera locks up randomly during use.
http://code.google.com/p/400plus/issues/detail?id=32
I use my camera for my line of work every week, once a week.
The camera acts weird in a few different ways.
I've never had a problem with the older versions as it was only small
changes such as ISO3200 and spot metering.
However I suspect due to the mass amount of code added and even a fully
implemented menu in the camera, the camera will behave unexpectedly.
The camera locks up during use. Here and there at random times.
I've experienced it locking up during shooting, or playback.
Forms of locking up that I've experienced are:
1. In playback mode, the left right buttons do not work, I can go next
photo with the index finger wheel and select items on the screen with it.
2. Camera completely locks up, will not focus, take a picture, no buttons
respond.
3. Camera focuses, buttons work, but will not take a shot.
All of the bus I've experienced were solved by a quick battery eject and
reinsert.

I cannot seem to reproduce the problems, please try to find something in
common or a way we can reproduce it.
Just a wild guess based on you description:
The first and may be the third problems are probably caused by entering
custom menu (400plus,shortcuts) and then interrupting it somehow (i.e. not
leaving the menu). Try not to leave the menu with focus/shot button or by
any other means of interrupting it, at least until we have a better way of
handling the menus.

I know random locks-up are hard to reproduce (precisely due to their random
nature), but unless I can reproduce a problem, there is little I can do to
solve it, sorry.

I understand that I have no precise ways to reproduce it.
I've encountered not one, but a couple lock ups during last night when
working.
As I'm working, I can't exactly pay attention to the problem, and it's all
in the dark as well.
I can tell you, I'm not using the 400plus menu at all.
The most I use is change to ISO3200, which is why I request to bring back
the disable the SC menu and change the DP back to an ISO button.
All I do is take pictures, press the playback button and show people the
image taken.
When I stand aside to review the pictures and when deleting some, I notice
that the left and right buttons are no longer working and there for it's a
form of a lock up.
The left and right buttons locking up is the one I've experienced the most.
Try and do what I do.
Take pics, review them, press shutter to turn off screen, and repeat for a
few pictures.
Then review the pictures and delete them.
That's the best I can do, for steps to reproduce the problem.

Ok, let's try some guesswork... could it be that you accidentally press
both the shutter and one of the cursor buttons at the same time? From your
description of your workflow, looks like you quickly change from review
mode to shot mode back and forth.
[Not trying to blame you, this is a bug nevertheless, just wanting to
isolate the cause.]

Comment #5 on issue 32 by kay...@gmail.com: Camera locks up randomly during

http://code.google.com/p/400plus/issues/detail?id=32
No, I don't push the shutter and one of the cursors at the same time.
I push the shutter only when I need to exit playback mode and back into
shooting mode, or after viewing the image.
Yeah, I'm a club photographer, so I take photos, and review them quickly,
then exit playback mode.
Then once in a while I would stand aside and go back a few pictures and
delete the bad ones, and like I said the camera would lock up once in a
while.
Gets frustrating, but since I have a battery grip, doing a quick battery
pull is no problem.

Our code intercepts the cursor buttons when the user has his face on the
camera (for both the "ISO in viewfinder" and the "nose affair" features);
but we know that the face sensor does not work when the display has been
turned off (issue reported by this same user, by the way). If our code
mistakenly interprets that the user has his face on the camera, then the
LEFT and RIGHT buttons would do nothing at all.
Just more guessing... I'll do more tests as soon as possible.

I have been bashing the camera for a good amount of time, trying to
reproduce this, but I couldn't; I tried to hit all the paths and buttons
that I could think of, to no avail...
I am not saying that this bug does not exist, but until we find a sequence
to reproduce the issue, I am afraid that I cannot do much more about it;
sorry.

I made some HDR shots this evening, with HandWave Script configured to
activate Ext. AEB with 5 shots. I've used the camera in this setup for
about half an hour and did not get any lockups... Still I reviewed the
taken photos with the Play button.
This weekend I'll make extreme use of the camera, hopefully I'll get some
results.

Hmm. I don't have another XTi to test this on. Maybe it's my camera only?
I can make a video of the problem happening.
I'll see if I can record what I'm doing and we'll see if it happens.
I'll post a link here when I have a video.
Don't worry. I understand that you would need to have replicated the
problem to troubleshoot what's going on exactly.

I have the video! I was able to replicate it. I do have an idea however.
It MAY have something with the idle time that is going on in between taking
photos.
HOWEVER, I'm only able to replicate it with my 580EXII attached, as my work
requires a flash.
I have my auto shut off at 30 seconds, and my image view time at 8 seconds.
It may be a combination of the two wait times over a few shots, and then
when I delete something I find out that the buttons are locked up.
Will link you to the video download as soon as it's uploaded.

I tried to configure my camera as similar to yours as possible, and then
repeated the same sequence of buttons you show on your videos; but after
lots of attempts, I still could not lock my camera. I do now own a flash,
so if you have determined that it only happens when you attach one, I will
probably never be able to reproduce it here.
Let's try plan B: I can send you special versions of AUTOEXEC.BIN, then you
test them and report back. It is going to be slow and tedious, but unless
you are willing to send me a flash, I do not see what else we can do.
Attached to this comments there are two files; please rename them to
AUTOEXEC.BIN, and try if you can reproduce the bug with each of them. Many
thanks.

Hold on, I actually remember that the camera has locked up on me WITHOUT an
external flash attached.
I was actually on the bus headed home, so I would review my photos to cut
down the workflow afterwards.
The camera has locked up in the same way before, just viewing photos.

http://code.google.com/p/400plus/issues/detail?id=32
I found a way to reproduce something similar to what you show in the
Videos...
I played with some new flags and found FaceStatus flag which shows what
reads Face Sensor...
so while I played with that flag I was able to reproduce this problem.
1. Camera in normal display (the main white screen)
2. put your finger on the face sensor ... so the display turns off
3. press play button while holding your finger on face sensor
4. photos preview shows up and left/right btns not working ... only the
dial...
so if that turns to be your problem it could be a broken face sensor (or
somehow the external flash is breaking its function)
it turns to be the same if you activate MENU instead the preview (PLAY)
with finger on the sensor. checked w/o the CF card to see how is working
the OFW and its working normally.

Precisely, the attached AUTOEXEC.BIN.2 file has all the face sensor logic
disabled; "ISO in viewfinder" and "the nose affair" will not work with that
version, but buttons will work normally in any dialog, even if we have a
bug in that path. I am waiting for user feedback, to confirm whether the
problem is there or somewhere else.

Mine just locked up while doing a timelapse with the intervalometer.
It was on Av mode, 2 sec intervals, manual focus.
The blue LED was blinking as it would normally do during a timelapse
however no button would respond and I had to take the battery out.
The screen was displaying the standard screen that shows you ISO/shutter
speed/etc

I experienced the "camera freeze" while in the 400plus "Settings menu"
adjusting values with the Av button. It occurred soon after I adjusted an
Intervalometer setting and then pressed the SET button to save my
settings. There does not seem to be any rhyme or reason for why this
happens yet... I tried over a dozen more times to repeat the problem and
could not reproduce it again. I will continue to try to determine a reason
for this.
The "camera freeze" required removal of the battery to continue. The
version was Release "20110425-0".

So far, there hasn't been any lock ups! So kudos! :)
I've just kept shooting and shooting during work, and no problems with
locking up!
HOWEVER, there is one thing.
Every now and then after taking a photo, (I have my review time set to 8 to
show the people right after), I accidently hit any button that brings the
camera out from review mode back into shooting mode.
So when I show the people, they say there's nothing on the screen, that's
how I know a button was pressed. (Most likely the shutter was half pressed)
So when they say there's nothing, I go and push the playback button, but
nothing occurs for a couple of seconds.
Usually I just battery pull, and reinsert and playback the image. (Which
works)
However, I've noticed that if I wait a few seconds and try the playback
again, (after the people say there's nothing on the screen, and the
playback button doesn't work) the playback button works fine.
It seems though it's like a delay.
As most times, taking an image then pressing the playback button right
after the camera plays back the image.
I hope you understand what I'm trying to describe.

Could you please confirm this is the sequence you are describing:
* Camera set to 8s review time.
* Take a photo.
* Wait for image to appear on display.
* Half-press shutter button (image disappears).
* Press PLAY immediately.
* Image is not displayed.
* Camera set to 8s review time.
* Take a photo.
* Wait for image to appear on display.
* Half-press shutter button (image disappears).
* Wait a few seconds and press PLAY.
* Image is displayed.
Many thanks.

Yes. Exactly like that.
The second sequence is what works most of the time, however, from time to
time, I've experienced the first sequence.
When I experience the first sequence, I just quickly do a battery pull to
speed things up.
But there has been a few times where I just waited the first sequence out,
and then pressed PLAY again, and it works.

Nope. All I can tell you is that after I take a picture, I would
accidentally hit a button (not necessarily the shutter button), and the
image disappears.
It seems to be a periodic thing that happens.
Not so sure when or how. It just happens.

The only time it seems to happen to me now is when my battery or gripped
batteries are getting low - even when the camera battery power indicator
shows they are not yet fully exhausted. I get a lockup or freeze (whatever
you want to call it) which power-off by itself does not fix (requires
pulling the battery or batteries). I do not believe this has anything to do
with 400plus.

http://code.google.com/p/400plus/issues/detail?id=32
i got the same problem with empty batteries on the grip, but i think this
is because the batteries are not reporting the current level (via it's chip)
instead the camera tries to measure the charge via the voltage of the
battery (may be)
so i do not think this is a problem we can fix in the firmware... may be
the original firmware will hang too, but when the camera restarts it (the
original fw) will manage to shut down the mirror and turn off the camera.
in our hack we hold the starting of the firmware with about 1.5 sec. so it
has no chance to shutdown the camera... the power is too low after 1.5 secs.
may be after we find a solution for issue 92, we can do the battery level
check at the init routine and shutdown the camera if it's not good. this
could fix this problem.

hi...been reading the thread and have experienced exactly same problems of
intermittent locking up, including not being able to turn camera off
without pulling battery pack out to reset, this has only ocured when a
bg-e3 canon battery grip is attached, never when the normal battery is
fitted, to test the problem i swapped grip to my other 400d and it did
exactly the same, first camera has an 16gb card with 20130414-00 bin and
second camera using same bin with a 2gb cf card.... the problem does not
occur on either camera when using 20120415-17 bin with grip or standard
battery, an old version that i have found really stable and has never given
me any problems...hope this is of some help
