I can only agree. I even sometimes have problems understanding him in his nativ language. Offtopic off ...

Sometimes I used the M100 with a 4m selfie stick via Bluetooh. The problem is that the camera emits a sound when focusing, although all sounds are switched off in the Canon menu. Is there a way to prevent this with CHDK?

Interesting. I noticed the same forcing rec mode over wifi (https://chdk.setepontos.com/index.php?topic=14294.msg145499#msg145499). Similarly reported with the official app in https://www.dpreview.com/forums/post/60937949

Maybe a Canon feature to prevent creep shots.

It doesn't seem to be directly described in the manuals, but some of them say the the camera will make a sound, with no mention of turning it off.

I don't know of a way to disable this offhand, but it seems likely it would be possible by poking a variable somewhere.

Although the shutter is much louder. The noise is annoying when you want to photograph animals.

I've tried rawopint.lua and MDFB2013.lua. Works very well on the usual.
I have a problem with the M100 and rawopint. So far I've only used the EFM 15-45 for this. There are no problems with that.

With the EFS 55-250 or a manual lens, the camera goes out on the second shot. After the crash, the camera's mechanical shutter is closed. This doesn't happen with a normal interval script.

I created a ROMLOG. There was also a GK.log that I haven't noticed before.

It's not crashing here, but there's a raw hook related fix in my source - perhaps that's why. I'll attempt to post updated source in a few days - will have to check trunk changes first.
In the meantime, if you still have the source snapshot, replace following in replaced.c
Code: [Select]
void __attribute__((naked,noinline,aligned(4))) hook_E004E928()
{
    asm volatile (
    "bl         capt_seq_hook_raw_here\n" // +
    "bl         clear_current_raw_addr\n" // +
    "mov        r0, r4\n"
    "bl         sub_e004c680\n"
    "mov        r0, r4\n"
    "ldr        pc, =0xE004E931\n"  // -> back to ROM
    );
}

void plant_hacks_for_e0040000(unsigned addr)
{
    place_fw_patch_t2_64b(hook_E004B840, addr+0xB840);
    place_fw_patch_t2_64b(hook_E0045B18, addr+0x5B18);
    place_fw_patch_t2_64b(hook_E004E6A8, addr+0xE6A8);
    place_fw_patch_t2_64b(hook_E004E750, addr+0xE750);
    place_fw_patch_t2_64b(hook_E004E820, addr+0xE820);
    place_fw_patch_t2_64b(hook_E004E928, addr+0xE928);
}
with this
Code: [Select]
void __attribute__((naked,noinline,aligned(4))) hook_E004E95C()
{
    asm volatile (
    "bl         capt_seq_hook_raw_here\n" // +
    "bl         clear_current_raw_addr\n" // +
    "ldr.w      r0, [r7, #0x184]\n"
    "cbz        r0, loc_e004e96a\n"
    "movs       r2, #1\n"
    "movs       r1, #0\n"
    "ldr        pc, =0xe004e965\n"  // -> back to ROM
    "loc_e004e96a:\n"
    "ldr        pc, =0xe004e96b\n"  // -> back to ROM
    );
}

void plant_hacks_for_e0040000(unsigned addr)
{
    place_fw_patch_t2_64b(hook_E004B840, addr+0xB840);
    place_fw_patch_t2_64b(hook_E0045B18, addr+0x5B18);
    place_fw_patch_t2_64b(hook_E004E6A8, addr+0xE6A8);
    place_fw_patch_t2_64b(hook_E004E750, addr+0xE750);
    place_fw_patch_t2_64b(hook_E004E820, addr+0xE820);
    place_fw_patch_t2_64b(hook_E004E95C, addr+0xE95C);
    *(unsigned short*)(addr+0xE95A) = 0xbf00; // nop (benign 16-bit instruction, added to replace 1st half of destroyed 32-bit instruction)
}

I mean I did everything right. But the crash remains.
However, I'm on trunk 5616. Would I have had to update that too?

No rush. I am waiting for the update.

In that case, can you detail the script and camera settings? Use a manual lens (= no electric contacts) as I don't have the 55-250.

No, that source is not compatible with current trunk.

After your changes, the cam now also crashes with the EFM 15-45.
Script is just rawopint 0.25 with default Params
