Hello! First of all, thanks for the amazing effort you devs have put into this firmware! I'm highly grateful for it as I only have a Canon 6D and I suddenly was enabled to create nice things with it.
However, I recently purchased DJI RSC 2 gimbal and its software kind of interferes with ML firmware and I cannot turn on MLV Raw without my screen in LiveView video mode freezing. When I turn back to photo mode LiveView, it gives me an error and asks me to turn off camera. After I turn on again, the screen in video mode apparently works normal. But I am getting this error everytime I turn on both camera and gimbal. Is there something to be done? I know it's kind of a particular problem not all users have, but I hope maybe there is a fast solution to it:)

The crash looks like this:
ASSERT: fInitialize == TRUE
at ./System/PostPostman/PostPostman.c:438, Epp:4886c
lv:0 mode:3

I have an RSC 2 and a 5D3 and I can confirm your experience.

However, after fiddling around, I found out that this boot-up sequence works for me:

  • Start with both cam and gimbal OFF, not connected
  • Connect camera to gimbal via USB cable
  • Turn gimbal ON
  • Make sure camera mode dial is on photo
  • Turn on camera
  • Check for gimbal LCD to report that the camera has been connected
  • Allow for SD overclock to be all set (if you have it enabled in your build: wait at least a couple of secs)
  • Finally, switch camera from photo to video
As I said this works for me, both in Framing and Real-time Preview. Hope it works also on 6D.

#5D3. I also can't record like without connecting the camera to the gimbal (DJI Ronin-S). I have to turn off sound completely and freeze LiveView. It would work though you can't see what is focused.
