hm, ASM is too complicated for me :D i guess i have to depend on the real gurus like you :)
anyways, i used your supplied address to compile a version for the s3is, maybe someone (barney?:D) can test it.

extern char* camera_jpeg_count_str;
and in every platform/xxx/sub/yyy/stubs_min.S:
DEF(camera_jpeg_count_str, variable address).

There is the error here. If you look to other variables, which use similar way of declaration, you will see that they do not have any (*) in their types.
You declared camera_jpeg_count_str as char*. It's the same as the variable on a target address contains a pointer to a char. So, you just declared the variable of char** type and assigned the address to it.
I suspect that the correct declaration is 'char[]'.

Kudos to you :)
i think i still want to use lib.c, as it only requires to change one file instead of two. next step would be to understand asm a little better and then add the addresses for the other firmwares. loading them into IDA properly will take hours alone :D
so if you have IDA, time, knowledge of asm and want to see YOUR camera having this nifty feature, tell me your address, you readers of the chdk forum ;)

edit: well, not your address as in where you live, but the address of the string the canon-remaining-pictures-value resides in ;)

You are right. So, my new vote in this poll: "I used the code off of GrAnd's branch but my edits are causing errors!" ;)

don't tease the gods, test the builds ;)

(please :D)

ewavr i suspect these are the addresses, right?
will wait for barney to verify that my code works, then i will implement those new adresses to the lib.c's. way to go :)

btw will this function have any (noticable) effect on energydrainage? i mean, i'm polling freediskspace at a rate of 1/30s (wild guess here) does that mean theres i/o being executed?

Of course.

I think that good OS keep free clusters count in RAM.

don't tease the gods, test the builds

tested:  * chdk_a620_raw_size.rar (196.63 KB - downloaded 1 times.)

replay mode: shows "1426M" (non <alt> mode)
shoot mode:  shows "120"     (non <alt> mode)

<alt> mode not tested, no usefull script loaded

JPEG setting: max resolution - lowest compression

that boils down to 1426/120 = almost 11.9 M for a JPEG/RAW pair.

suggestions for improvement: show only when raw actually activated

result: success  :)

P.S. What was actually changed in this build ? gui_bat.c, or lib.c too ?
