Here is Chronos 1.4 Software V0.3.2-RC2. Do not use this software version if you are capturing something that is not easily replicated.
+----------------------------------+
++ ++
| Chronos V0.3.2-RC2 Changelog |
++ ++
+----------------------------------+
Notable Changes:
- Automatic ADC calibration during black calibration, which should reduce column banding across a wider temperature range.
- Add a storage tab to the util menu to view, eject and format the attached storage devices.
- Speed boost at most resolutions, with a top speed of 1069fps at 1280x1024, and 40420fps at 320x96.
- Configurable automated power-on and off depending on the AC adaptor status.
- Option to disable the ring buffer when in segmented recording mode.
Minutiae:
- Factory black calibration is now user accessible from the Factory tab of the util window.
- The software update button has been moved to the storage tab of the util window.
- Shipping mode to disable power-on by battery until an AC adaptor is attached.
- Add a watchdog to reboot the camera in case of a power-on boot failure.
- Display descriptive error strings instead of number on failure.
Minutiae (relative to RC1):
- End of recording from lack of free space generates a warning dialog.
- Revert to a valid resolution when focus is lost while editing the H/V resolution widgets.
Fixed Bugs:
- Gated burst record mode may lock up after several trigger edges.
- Gated burst record mode unreliable when trigger debounce is enabled
- Memory leak in the M3 video coprocessors which could lead to a crash after lots of H.264 encoding.
- Ignore video which was recorded during zero-time black calibration (which happens after changing resolution).
- Stuttering issue on the playback window on new production LCD modules.
- Fixed deadlock in camera when restoring user settings from external media.
Fixed Bugs (relative to RC1):
- Corrupted overlay text at narrow resolutions.
- Video stream would remain in playback when starting recording via auto-record.
- Opening and closing the white balance menu can lead to an unexpected change of the custom preset.
- Bug in calculating the trigger delay on boot (segmented mode only).
- Ensure a minimum of 0.25 bits/pixel when encoding h.264 video.
- Crash can occur when saving extremely short videos.
- Lag when focus peaking or zebra stripes (focus and exposure aids) are enabled
- On the save file settings window, the bitrate as listed above the resolution may be lower than the actual bitrate, if Saved File Framerate is lower than 60fps
Fixed since V0.3.2-beta-6:
- Changes to focus aid or exposure aid (zebra stripes) would have no effect until resolution is changed.
- Changes to exposure may be overwritten during black calibration.
- Bad image quality at 336x120 resolution
- Util window, storage tab - bottom of text cut off if device has multiple partitions
- Factory black cal (black cal all resolutions) would get overridden by old user black cal, if a user had done their own black cal, even before.
Known bugs still in V0.3.2-RC2:
- Video system may crash after about 200-300 saves, on average. (bug present in RC1 and RC2)
Updating Your Camera
====================
- Extract the `.zip` file into the root directory of a FAT32 formatted USB drive.
- Turn on your camera and insert the USB drive into the USB/eSATA combo port, not the one labeled 'OTG'.
- From the main window, tap the `Util` button to open the utility window.
- As a precaution, tap the `Backup Calibration Data` button on the utility window before starting the update.
- When the backup is completed, a pop-up window will be displayed.
- Tap the `Done` button to close the pop-up window.
- From the utility window, tap the `Apply Software Update` button to begin the software update.
- A warning message will be displayed, tap the `Yes` button to confirm and begin the update.
- If a pop-up that says 'No software update found' is displayed, even when a USB stick containing the update in the correct location is connected, reboot the camera and try again.
- During the update, the screen will go blank and an `Applying Update` message will be displayed.
- After approximately 60 seconds, the update will be complete and the camera will restart.

Great News!
Do we have to factory calibrate after applying this update or just use it as is? Will test this weekend. Thank you!

No, it's not necessary to factory calibrate after the update. That feature really just does black cal for all of the standard resolutions.

Ok did some testing...
Everything works as expected with what seems improved column noise pattern reduction after calibration. It still requires camera warming up to get to a point where the calibration works pretty well, that is about 26 minutes warm up.
Fan goes faster when using AC power vs the battery, that is to be expected.
1 Bug Found: when using HDMI monitoring, you activate the focus asist function (peaking) on the camera and it slows to a crawl then image locks up and no motion is attained. Only fix is unplug the HDMI cable and things return to normal. Camera refreshes signal and regular operation resumes.
It seems the cpu is overwhelmed when peaking is activated and HDMI is operating. Tried with a field monitor and an LCD viewfinder both showed the same problem,
Great job on the nice features like improved fps and storage info + format options, much appreciated! :D

Hi all
I upgraded to this latest release as well and have experienced the same freezing/lack of response issue. In my case though I was messing around with a new lens which was heavy. I did not have an external monitor connected however the screen was rubbing against me as I messed around with the back focus adjustment. I didn't spot a pattern to it but it was doing it regularly. I tried one short recording whilst it was stuttering and that seemed to record ok. I have gone back to the beta in the mean time.
-
Also had this freezing / lag issue.
Essentially slows the display to a crawl and makes it near unresponsive. No set pattern but focus peaking don't help!
No monitor involved either.
-
I tried a few things and I'm not having any stuttering or freezing issues on the new firmware. HDMI out works, focus peaking is not a problem. I'm letting the camera warm up a bit more now to see if I'm affected as well but so far it doesn't appear so.
Edit: I decided to test the "Restore Default Settings" option and it just displayed the shutting down screen for 20 minutes without progress. I had to do a hard reset, but it seems to work fine again. Probably not related and a non-issue for me as I'm not intending to revert to factory settings often.
-
Thanks for the feedback, guys. We've been able to reproduce both the focus peaking lag and the issue with reverting settings and are working on fixes.
About reverting settings - it's actually OK to shut down the camera right when the shutting down screen is displayed - no need to wait.
-
Thanks so much, looking forward to the peaking patch, I miss the feature big-time since my monitor peaking is not as accurate as the one you guys have been able top include in-camera!

Found another small problem.
In Firmware 0.3.1 the first frame of RAW DNGs was completely white and now Frame #1 is still full white and now new bug Frame #2 is the last frame of the recorded area instead of the second frame in the sequence as it should be. This is happening for all saved sequences. It is a minor inconvenience as I have to delete both 1,2 from the sequence before processing.
I did notice saving is much faster on SD cards for some reason on 0.3.2 RC1, I am getting 4.5-4.8fps instead of 3.8 as a maximum before. Very welcome change! ;D
-
Thanks for finding the bug.
I just tried to reproduce it on my camera, and it actually happened with all the save formats that I tried, not just DNG. Also, the frame was copied from whichever frame is currently visible, not necessarily from the end of the selected region.
-
Interesting, thanks for the testing the camera is getting better every day!

For anyone who wants to downgrade from software v0.3.2 down to v0.3.1, please use this package: http://forum.krontech.ca/index.php?action=dlattach;topic=460.0;attach=575

The new 40420fps setting worked great! It seems to break the text overlay though. Not really a big deal as the text overlay covers about 1/3 of the image...
-
Another small bug:
In the Util Menu, sometimes "clicking" the tabs does not change to them but only highlights them.
See the following image of an example:
"About" is selected but the "Kickstarter" Tab still displayed.
Also the issue I accidentally reported in the wrong thread:
I just noticed a significant lag on the screen update if the overexposure-warning stripes are shown. It appears to drop down to single digit FPS and takes a few seconds to recover even after the bright spot is gone. I noticed this after the screen upgrade, but they can't possibly be related. I have not tried yet if recording is somehow affected.
If needed i can provide a video of the "slowdown" happening.

Thanks, I've added this to the list of known issues as "Lag when focus peaking or zebra stripes (focus and exposure aids) are enabled"

Do you know if this only started when the screen was upgraded?

Sadly I don't know for sure, but I don't remember similar issues with the old one.
If needed I could put the old screen back and test it to be certain.

I have the above mentioned lagging/stuttering issue as well as no video when using high gain at the max framerate. It's not a combination I am likely to use but I was checking it out of curiosity. I'll see if it is repeatable when I get some time.
Otherwise it looks and works great!
-
V0.3.2-RC2 has been added to the OP, along with the changes since V0.3.2-RC1.
-
I can confirm the lag issue is gone now. The "Tab is only highlighted and not selected" issues might have gotten a bit worse, but it's hard to tell. I have an estimated "errorrate" of about 1 in 4. This is close to the point where it gets annoying. I did not put the old screen back jet to test the source of the issue though.

According to foobar, we may need to update calibration data for the new LCD panel to fix this:
The response of the touch screen may not be in perfect alignment with the LCD display. Normally this would be fixed using calibration software to align the touch inputs with the underlying LCD. On the old panel, the geometry was close enough that we have never really needed to perform that step, we may need to update the tslib calibration data for the new panel.

That makes sense but would imply all of your 2.1 cameras had the same "issue" ?! Let me know if I can help in any way.

I used the latest beta RC2 and the lag on peaking with an external monitor is gone but now the camera hangs on displaying video at random junctures. The interface somewhat works but the exposure bar and live feed are gone or frozen. Only fix is getting the camera to shut down and start back up. Happened about 7 times in a 4hr period. No idea what is causing it, I tried with and without HDMI plugged in and behaved the same way.
The frame selector bar on play tries to adjust but it's pegged at 0 and frame 2 even when you try to scroll higher or lower. No image is displayed either.

Is the full version of 0.3.2 any better? http://forum.krontech.ca/index.php?topic=505.0

Will try and report back, was not aware of it sorry!
