Full-resolution silent pictures (silent.mo)

Ok, I think I have figured out how to read the two first addrs. Well, I have some doubts with capture_err_time_addr, because the instructions here:
https://www.magiclantern.fm/forum/index.php?topic=12523.msg171606#msg171606
and
https://www.magiclantern.fm/forum/index.php?topic=12523.msg170756#msg170756
give somehow different recipes to obtain it

So, in summary, bulb_end_addr = 000760e8 + #20 (dec) = 00760FC and  capture_err_time_addr = 0xFF1C550C ? (line ff1c56bc:   e51f41b8    ldr r4, [pc, #-440] or is it 0xFF1CAB5C? (line: 00004e20    andeq   r4, r0, r0, lsr #28)

Code: [Select]

if (is_camera("6D",  "1.1.6"))
    {
        bulb_end_addr = 0x760FC // or 0x760F8 ??;
        capture_err_time_addr = 0xFF1C550C; // or 0xFF1CAB5C ???
        frsp_tv_addr = ???; // cameras with SHOOTMODE_BULB need fake SHUTTER_BULB
}

What I don't know is how to get the frsp_tv_addr. There is a script from Greg, but I really don't know what to do with it. How do I compile it? Or is there any way to look for it directly in the BIN file like for the other two addrs?

Hello friends.

I see that only the 1100D does not support the silent shooting function.
What is the reason that this particular mod doesn't support it? It is strange when it is available in all other cases. Maybe it just requires re-compiling the code for this model.
I want to use it in astronomy, and the mechanical shot makes the telescope vibrate a bit. So I would like to avoid that.
I have this camera. so i can do the tests. I am also a programmer of embedded systems and firmware, and other software products. so i can help you with that.
But I would like to understand the state of affairs and what it is connected with.

Thank you.

p.s. Sorry if I asked something wrong or out of order.

Builds for me for 1100D, but I'm using a different repo and you can't use modules from it.  Probably you could build from whatever repo you're using.

You could also lock the mirror up before shooting, it's a standard Canon setting.  Should be in Custom Function 8.

No MLU for xxxxD.

I got the claim from here - I don't have 1100D to check: https://www.dpreview.com/forums/post/38311112

I see that only the 1100D does not support the silent shooting function.

Are you using Nightly build?

It seems 1100D nightly build doesn't include silent.mo, but "lua_fix" branch does have silent.mo for 1100D, have you tried a build from that branch?

So I took it from the Nightly build.

Okay, I got you. I'll try to get it another way.

I will also check the recommendations regarding lock the mirror.
