Canon hasn't added any protection measures.  We can already run code on Digic 6, 7 and 8 cameras.  I don't know where this idea is coming from.

I used the wrong word. I should have said that Canon changed to newer CPU architecture that are more complex to reverse engineer. But by switching to newer ARM processor does in fact requires modder to redo almost everything from scratch.
Sorry, but I was a little bit confusing when I wrote the post above.

@KenSoftTH,

Not every man on this forum can earn "serious amount of bucks" and invest it on the camera. Which camera, by the way? There are quite a lot of good Canon cameras that can shoot raw, using ML, in highest quality previously available when using profi cinema cameras only. And these Canon cameras cost much, much less than those profi cinema cameras - I mean, Arri Alexa, Red (any), etc. There are cheap SD, CF cards (comparing to the profi cards or whatever), cheap lenses anyone can get great videos with. You can make almost any kind of image using raw from these Canon cameras, and this, may I call it, ML RAW SYSTEM costs much, much less money than any of those professional cinema raw systems. OK, this is all just my POV, but anyone already can make documentaries using ML raw. Using their own cameras, not the rented ones. And I want to thank all programmers that are working on this great project that, undoubtedly, has great future. I'm from Russia, for instance, and we have hard times by now (economical crisis, dictatorship, etc), but even now (!) I can afford myself shooting ML raw in highest possible quality, and I'm going to further evolve my raw system, because, again, I CAN afford it myself without investing tens of thousands of bucks into it. Just as I can afford myself to record sound (music) on tape from the mikes - and again, without those great investments. I can get great professionally looking picture for some hundreds of bucks with the camera that costed me... um... $200 with lens (!). Of course, there are BMCC, BMPCC, etc, but, to my mind, ML raw is better and even more cheap. ML is free of charge, by the way, isn't it great?

Go re-read my post. I know that not everyone has serious buck to afford those camera. I said that anyone who has the knowledge in ARM microprocessor or VLSI will earn serious buck and won't spend their time doing the hacking unless they are passion about it. You guy are expecting to do 4K, 6K or whatever, but there are many contraint in both hardware and software that developer need to overcome and many time it's just better off buying the camera that has that feature in the first place instead as it would be more stable in most cases. I'm not saying that it's impossible to do it, but it does require more brain power than ever before as Canon implement more and more lockdown on its firmware.

Just come here to post final update. I bought the Canon 90D and I'm not going to work on this anymore.

Seriously guys, anyone who have knowledge on this field can earn serious amount of bucks and it doesn't worth their hassle working on the custom firmware for free. They're better off spending their money on the camera that does the work in the first place.

Like others said, it just not worth it.

Hi,

I'm working on 7D2 port, but since it's the same CPU, can someone guide me the way to extract raw frame from video mode? I got hello world working a few months ago but don't have any idea how to continue. Please guide me a little if possible.

Thanks!

@a1ex,

I did some test regarding the buffering of 7D Mark II. I went out to shoot the timelapse and noticed that if I set resolution to mRAW (4104 x 2736) with 6fps burst rate, then I can shoot until my 32gb 90MB/s SD card filled. I noticed that in the mRAW file, there is L-Fine JPEG attached (full sensor resolution) and total file size for each mRAW frame was 16.3MB at ISO 100 and seems like the card is the bottleneck. If we managed to port magic lantern onto this camera, can we turn off JPEG preview, reduced bit depth to 10 bit, recording to CF and hope for 4K 24fps video? or the sensor readout rate will be the next bottleneck? Just wanna know from your experience and what to expect.

OK, I will do that after the long holiday here in Thailand. I think it's 512MB for each CPU because it has similar buffer size to 80D (why they would put half memory on higher end camera) and taking sequence of continuous shot reveals half of JPEG processing log compared to number of images, that means other half is processed by another CPU?

It only dump the first one second, which is useless. File size seems to be limited to 2048KB, which only contain interrupts and boot sequence.

Update: Seems like 4 log commands reveals 6 file, 4 is almost empty and 2 are fill with goodies

After playing around, I noticed that video seems to not output any log (the log above is for still photo) and the log start to have something when you fill the buffer during continuous shot. This make me believe that I'm currently thinking that the log seems to be from the secondary processor.
