Canon 5D Mark IV

[names_are_hard]

I have a question guys, do you still work on the MK IV, how is it going?

There are no current devs who own a 5D4 and nobody is working on it.  The cause of the current show stopping bug is unknown and hard to diagnose without access to a physical cam.  Once it is resolved progress to the same level as the early 200D port could be fast enough, progress beyond that will be slower.

There will be no progress on 5D4 until we get the combination of dev + cam.

I see. Thank you for the respond, if there is something new going on please write, it's so interesting to me.
Thank you all guys who made Magic Lantern happen, it's really a magic. If it's meant there will be a release for the 5D IV, if not thank you for trying. I really appreciate your work, you are awesome.
Thank you all of you, wish you happy holidays and i hope this year to be better than the previous for all of you!

Hi - somehow I missed this message.  If you're still interested, we have a testable build (with very limited features) for 5D4, but it crashes early on.  Probably, you will want to get UART access to your cam (not hard for this model) in order to debug.  No active devs have access to a 5D4 with UART.

It should look like this, under the thumb grip:

Some cams have the socket soldered, some don't.  We have Gerber files for ordering a flexible PCB to connect to the socket.  We know the socket part if yours doesn't have it and you want to add it.  Otherwise, you can use whatever probes work for you to contact the right pin.  You only need one pin connected to get debug output.

I have a 5D4 also and would be interested in helping. What exactly is the issue and what do you need? Would be happy to meet up with a dev if there is one in my area (NC) and they can promise not to brick it 

Sad to see how slow development has gotten on ML, I loved this software on my t3i and my 6D.

We don't know the exact issue.  We know it crashes during early boot.  We don't have good logs.  If you're happy messing about with a serial port and working out how to connect it as described in my prior post, I can talk you through the details.

There are approximately three devs.  I don't believe any are in NC
