Were to upload crash log?

[Lucagw]

I would like to ask where i can upload the log for a crash ending with error 70 in my 600d. I was using mlv  module and various setting i.e. fps override. If i go to bug report i am redirected and cannot upload photos.
Thank you.

What build are you using?

[Lucagw]

Experimental lua.fix 2020.
Also find how to log in heptapod and upload files.

I think this is yours: https://foss.heptapod.net/magic-lantern/magic-lantern/-/issues/2978

I don't think anyone uses that bug tracker anymore.

The image is a good start, but there's not enough information to attempt to reproduce the problem.  I don't have a 600d and mlv problems won't reproduce in qemu, so I can't really help.

[Lucagw]

yes, is mine.
this is crash00.log

hope this can interest someone, there is also another file log00.log with the same timestamp that i cannot open.

Does this crash always happen if you perform the same sequence of actions?

You can upload the logfile without opening it.  It is just a text file so I don't know why you can't open it.

[Lucagw]

Opened in a windows pc (was unable to open in Buster, strange, it tell me it's codified with a not compatible format)
it's quite long , will upload in opened bug in heptapod.
I think it's a problem of writing speed on sd maybe. I'm using a Lexar 128 gb c10 3 1066.
Not repeated yet the same sequence of actions.
Started recording, The recording was stopping after 3 sec then i was pressing LV button again, stopped after 3 sec, again LV button and so on for several times until crashed.
Maybe in the log is more detailed...

[Walter Schulz]

1066x is for proprietary overclocking protocol. 600D does not support this.
Canon implemented a very slow UHS-I mode in Digic 4 cams (like your 600D). Cam can do 25 MByte/s (theoretical bandwidth).

[Lucagw]

I think will be useful for me reading the post aboud cards, i remember to have seen something in the forum...
All cards i have are micro sd except an old 1 gb sd card.

[names_are_hard]

If it only crashed once and it's not repeatable, probably nobody is going to investigate this.  Thanks for uploading the logs, now if somebody wants to look at it they can.

The core problem here is that you're trying to record in a mode that requires more speed than your card / cam can provide.  You'll need to use a better card, as Walter suggests, or record in a lower resolution mode.

[Walter Schulz]

A better card would do nothing. Cam limit is 25 MByte/s no matter what.

[Lucagw]

I finish now to read posts about crds and supported video res for different eos series cam. It appears clear that 600d has limits and 720p is the max this cam can afford.
I recorded clearly with an unsupported mode, so the cam crashed.
Thanks to all for the help.

[Walter Schulz]

Invalid conclusion.
Buffer overrun should just terminate recording and not cause crashes.
720p is out of the question for continuous raw recording.
540p is more like it.

[names_are_hard]

Walter - my mistake, I thought you were saying this card was UHS-II and UHS-I fallback was making it even slower than the normal slowness.

While it's true it shouldn't crash, it looks very likely the crash is related to exhausting something due to not being able to keep up.  An intermittent crash when trying to do something the camera isn't capable of?  Very low priority to investigate.

[Lucagw]

I agree, just from my newbye point of view was something that wort to mention.
I will continue to investigate and learn functions of the  experimental-lua-fix.
Also interested in learning how to set up an environement for compiling for my 600d.
I am interested in astro.mo module, but will write in the right thread.
Nice to see such activity in ML project... wonderful!
