Oh well ok, i thought it would be more complex since maybe Canon doesn't want us to downgrade.

Thanks, I'll try it.

Hi guys,

I was really happy with ML on my 7D. But unfortunatly I gave it to a CPS partner to check the AF with my 70-200 on the 7D. Now I have the 2.0.5 firmware running and therefore no ML possible.

Is it possible to downgrade to 2.0.3(with Linux)? I found something online but it requires Windows, but I have no Windows avaible until next week.

Any hints? Thanks

Any news when the dottune module will be avaible for the 7d?

[edit] nevermind, was able to use the dot_tune.mo from the 5d3 nightly build awesome work, thanks

I tested the card with ChkFlsh under Windows and with Linux, i wrote random data at it with dd if=/dev/random of=/dev/sdd1 bs=1k and vice versa tested for reading with dd if=/dev/sdd1 of=/dev/null bs=1k.

No errors occured with the Windows nor with the Linux version. So i would i say, the card is fine.

Thanks for your reply, I'm aware of the causes that might lead to corrupted data. I just wanted to ask here, if maybe this behavior is know and if this was really was triggerd by magiclantern, if there would be a chance to get a log or so.

But, regarding all facts, it might really just have been corrupted data. So i'll install ML again and be happy

thanks

Thanks for your reply.

Well it could be the card, but i don't believe so. The card isn't the cheapest one(Kingston 600x), sure not a fake nor is it very old(2 months) and hasn't many read/write cycles.
So, of course it could be, that the card is broken, but i will figure this out with a bunch of tests.

[edit] ran some tests with linux and windows on the card. No errors, everything fine 

Hi guys,

I used ML Alpha 2 on my 7D a lot lately and really loved it. But today i ran into some trouble.

I was taking pics as usual, camera went in standby and then it happend. I couldn't power the camera on again.

So here is what i did:

-) Remove the battery(both of them[battery grip]) and waited
-) Removed the batterygrip and tried with one battery
-) made sure the battery was fully charged
-) removed the buffer battery for about 20 minutes
-) removed my primary CF card(with magic lantern in it) for 20 minutes
-) changed the lens

None of the above worked, i couldn't turn the camera on again. No red light when putting the card or battery in, just no reaction

So, what got my camera back to life?

-) Removed the magic lantern CF card,
-) removed the batteries for 5 minutes
-) inserted a fresh formatted card

Camera booting again, everything fine

But: i wanted to read out the images of the (corrupted) card on my PC. Windows told me, that the card has to get formatted. Linux(Arch) told me, the card contains a bad superblock.

So I'm here right now, rescuing the data from the card. This whole thing caused me no real damage, but it would be a pain in the ass, if I really would need my camera and this would happen again.

Long story short: Still in love with magiclantern BUT: how did this happen? Is there a way I can get a log file or something I could send the developers? How can I avoid such failure?

Thanks and keep up the great work
