Here is a log file from the May 6 build session.

https://www.dropbox.com/s/khu85t3qxr1asa7/dm-0000.log?dl=0

Using this build of ML, the camera still freezes after formatting the CF card. However, this time, only the red LED stays lit. The blue LED is not lit and does not flash.


EDITED TO ADD: The above behavior is what should be reflected in the log file.  Just tried this again (turn camera on, take a photo, format card). First time it worked. Card formatted, camera restarted and did not lock up. Tried it a third time-- camera locked up with both red and blue LED solid. Fourth try and camera locked up with no blue LED/solid Red LED.

It seems that if the startup log process is still happening, it locks with only the red LED. If I wait for the startup log process to be done (blue stops blinking) I lock up with both LEDs solid. Not sure how/why it didn't lock up that one time.

Added a change to startup-log in order to check this hypothesis again. Can you try?

Sure, but where to do I find the new files? I only see the original May 2 version for the 50D.

The shutdown process appears to run normally, as far as I can understand from it. The display appears to turn off, but the blue LED keeps blinking, according to the log. Is this what you are seeing?

Almost. After formatting the card, the camera attempts to restart. The display does turn off. At that point both the blue and red LEDs are solid (no blinking). Camera is completely unresponsive. "Off" switch does nothing. Battery must be removed and re-inserted.

Removing the battery shuts off camera (obviously). Re-inserting battery allows camera to start up normally.

This is all the "standard" freeze on format behavior I have experienced with all "nightly builds" I have tried.

I'm not sure if we can catch Canon's debug messages during this lock-up, but let's try. You can use this build:

https://builds.magiclantern.fm/jenkins/job/startup-log/

It logs everything that happens in the first 30 seconds (while the LED blinks), then it saves a log file. If you can catch such a log, that covers the card formatting process and the lock-up, please upload it.

Whether the lock-up can be caught by this logging code or not, depends on whether DryOS is still alive after the crash (which I don't know yet).

These logs would also help me emulate the 50D in QEMU, btw.


Here's the log file.

https://www.dropbox.com/s/6abu1k1h4zolgfy/dm-0000.log.zip?dl=0

It's zipped and in DropBox. Can't see how to attach other than an image to a post in this forum.



edited to add: As expected the logging version also locks up the 50D after formatting a card. However, it also adds another issue. After the battery is removed, the camera will no longer start up from that card (removing and re-inserting the same card does not help). I need to insert a different CF card (which happens to be non-ML) and start up. After I shut down and re-insert the ML card, it will start up again.

Back again...

Perhaps I didn't ask the right question. I uninstalled the ML version from my camera. I then downloaded and installed the June 16, 2016 (#403) version, which I thought was supposed to fix the crash on format problem. It did not.

Can someone let me know which version of ML I can install that will not lock up the camera when formatting the SD card?

Thanks.

Thank you. I'll give it a try.

edited - Now I see. The versions are listed down the side on that page. Based on the earlier post, I see that I need version 403 or earlier (not 409 and I originally typed).

I'm curious. If 403 (June 13, 2016) is the last build that doesn't freeze the camera on formatting, then the problem has existed for almost a year. Looks like there have been several updates since then. Is this a problem that can't be fixed? Does everyone using a more recent build simply remove the battery after they format?

The current "nightly" build still hangs my 50D when formatting the SD card. Requires the battery be pulled to turn off/restart camera. I know this is an old issue.

There used to be an older "stable" build that did not have this problem. However, I only see the nightly available on the download page.

An earlier post on this board made a reference to build 409 or earlier... looking at the available downloads, there it no "409" or similar. The naming conventions are all date based.

Where can I get the older version without the problem?
OR
Is there a workaround/solution for the crash on format issue? (Or does everyone simply remove their battery when formatting?)

Thanks.

EDITED: Arrgg... just read the last few posts. (After finding nothing in google and forum searched).

I am also having the freeze on card format in camera. Using the Aug 24 nightly build. Have reverted to an earlier version for now.
