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:
give somehow different recipes to obtain it

Code: [Select]

At some point I see

Code: [Select]
ff1cab44:   ebfdef3c    bl  loc_ff14683c
ff1cab48:   e59d0044    ldr r0, [sp, #68]   ; 0x44

ff1cab58:   ea00000c    b   loc_ff1cab90
[b]ff1cab5c[/b]:   00004e20    andeq   r4, r0, r0, lsr #28
ff1cab60:   ff1c9dd0            ; <UNDEFINED> instruction: 0xff1c9dd0
ff1cab64:   ff1c9df0            ; <UNDEFINED> instruction: 0xff1c9df0
ff1cab68:   ff1c9e04            ; <UNDEFINED> instruction: 0xff1c9e04
ff1cab6c:   ff1c9e24            ; <UNDEFINED> instruction: 0xff1c9e24

ff1cab74:   ff1c9e58            ; <UNDEFINED> instruction: 0xff1c9e58

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?
