General Development / ARM Toolchain
July 03, 2012, 02:36:55 PM
I've built the toolchain, had to use -mlong-calls in Makefile.inc, but I got ML compiled.

In platforms/, there is a folder 50D.109. Does this mean I need firmware 1.0.9 on my 50D? I currently have 1.0.8 and the ML release from December.

This is a continuation of my post on vimeo as this would seem the more appropriate place for discussion. I tried to join the mailing list but there does not seem to be an option to do so; is that because we should be using this forum?

Anyway, I'm currently working on a PhD research project, and I wish to either detect the start/finish of video recording (preferably), or be able to trigger video recording via an external signal.

a1ex suggested I use a half shutter press to start recording via the remote port, but I couldn't find this option on my 50D. digging through the ML source code I found:
    #ifndef CONFIG_50D
    {
        .name = "Movie REC key",
        .priv = &movie_rec_key,
        .display = movie_rec_key_print,
        #ifdef CONFIG_5D2
        .select = menu_binary_toggle,
        #else
        .select = menu_ternary_toggle,
        #endif
        .help = "Change the button used for recording. Hint: wired remote."
    },
    #endif


so it looks like 50D does not support this feature.

An ideal case would be to somehow trigger the flash signal in the hotshoe when recording starts/finishes, has anyone managed to get ML to control the hot shoe signals? I guess this would involve some digging into the firmware..

I would appreciate any help that can be offered on this matter!

thanks!
