Hi asm,

The CHDK menu is white-black-gray in record mode. Is this bug or feature?
Did you check malloc() and strcat() ? I have some problem with these functions. 

Thanks,
Alex.

Hi Alvm,

I did'nt choose a good palete I think, you can change it in the config menu,

I also think these two function works, malloc is used quite a lot through the code, where do you have problems?

ISO override and Flash crashing in new cams (sd4000 and sx210 for now)

Diging into that I'm trying to isolate the issue in the sx210 it crashes at FF972E14 when its called from

capt_seq_task() -> sub_FF87E4E8_my() -> in loc_FF87E678 -> "BL      sub_FF972E14\n"

This sub is called for flash stuff

Did you base your SX210 code on some of my SD980 code? If so, that would explain the problems with the flash and ISO overrides. I was never able to get them to work properly, although they didn't crash the camera. I think the problem with the ISO override is that the camera doesn't use the exposure you set, instead it underexposes the pictures by quite a bit in order to get more DR out of them. So it might play with the ISO internally a bit.
The flash was never a priority of mine, so I didn't work too hard at it.

I based my code mainly in sx200 , some of your sd980 and some shared discoveries with pixeldoc's ixus300

Iso overrides seems to work in sx210 as far as I tested, just crashed with the flash enabled

I'm testing it in manual mode, and I also think is something related to exposure

More on flash and Iso override crash

capt_seq_task() -> sub_FF87E4E8_my() -> in loc_FF87E678 -> "BL      sub_FF972E14\n" ->

In this last function seams to crash when calling sub_FF8DC748__MainFlash.c__0

and this sub FF8DC748 seams to be some property works like:

FF8DC7A8  -> 0x108 ->  PROPCASE_TV                       264  //ASM1989 looks like
FF8DC7D0 -> 0x17 ->PROPCASE_AV                        23
FF8DC7F4 -> 0x4F -> PROPCASE_DELTA_SV                  79
FF8DC818 -> 0x51  -> Propcase 81 ?? what for looks 0 allways??
FF8DC83C  ->0x50  -> Propcase 80 ?? what for looks 0 allways??
FF8DC860 -> 0x4D  -> Propcase 77 ?? what for looks 0 allways??
FF8DC884 -> 0x79  -> PROPCASE_FLASH_ADJUST_MODE          121  //ASM1989  dont know allways 1 ??
FF8DC8EC -> 0x8D  -> PROPCASE_FLASH_MANUAL_OUTPUT    141       //ASM1989 looks like moves from 0 to 2

loc_FF8DC924......

FF8DC93C  (*)-> 0x40  -> PROPCASE_FLASH_SYNC_CURTAIN         64     //ASM1989  dont know allways 0 ??   anyway sx210 dosnt seam to have one

FF8DC960 -> 0x130  -> Propcase 304 ?? what for looks 0 allways??

->CRASH somewhere bellow this at FF8DC9B0

loc_FF8DC9D.......
 
FF8DCA0C (*) -> 0x130 -> Propcase 304 ?? what for looks 0 allways??

(*) Other function _sub_FF891554__PropertyCase.c__496, the other without (*) call to sub_FF891600__PropertyCase.c__0

Any clue from someone?

diging into unknown propcases:

0x51  -> Propcase 81
its called also from:

@asm1989

Thank you, will be installing today.  There seemed to be some site maintenance that prevented me from participating earlier.

Thank you very much

@asm1989

malloc() is OK, but strcat() has wrong address 0xff813f5c. The address which I've found is 0xff8aec20. Could you fix it, please?

stubs_entry.S from sx210-ixus1000asm1989trunk958

NSTUB(strcat, 0xff813f5c)
.....
NSTUB(strncpy, 0xff813f5c)

Thanks alvm, you are right, confirmed with sx200 too

Version 1.2.4 OUT

Dont know yet what it fixes, but thanks to alvm the function strcat was autodetected incorrectly
