Thanks for the source code, I compiled it and it works ;)

I haven't found any bug, raw pictures are good, and all the menus seems working correctly.
I don't have much time nor much experience, but I'd like to contribute. Now I'm just looking at the source code to try understanding how it works.

When making chdk load automatically you need to press 2x fast on/off button or replay button. Either way, camera starts in playback mode.

Dof calculator ...i always get S/R1/R2: inf/inf/inf

I'm using DNG for Powershot with EXIFTool. I end up with a .DNG file I can edit with Photoshop.

Hi, I've installed the firmware. The thing is thar I tries to make the firmware bootable but after locking the SD card it doesn't get on (if I retire the SD or unlock the SD it works as usual with the official firmware).

Could anybody help me?

hucht, the firmware is in beta...You have a problem that we know, and we are working to resolve!
...if you want help us, download also the source!

p.s. read old post...

Last Update:

- Dof calculator solved!  :D

I know is it few...but I' don't have time (and help)  :(

for denvelopers:

The problem was GetFocusLensSubjectDistance bad address, update stubs_entry_2.s...

but I'm confused... :blink:

well, i have found correct address: 0xFFE43B08

and see that function GetCurrentTargetDistance is:

STR     LR, [SP,#-4]!
BL      sub_FFE43B08   <-- call to GetFocusLensSubjectDistance
MOV     R0, R0,LSL#16
MOV     R0, R0,LSR#16
LDR     PC, [SP],#4


mhhhh....what are the difference by GetFocusLensSubjectDistance and GetCurrentTargetDistance??
I think GetCurrentTargetDistance call only GetFocusLensSubjectDistance! is it true?!

I had verified also with other firmware (ex. a610) and is the same!  :blink:

i test in debug and for my cam GetCurrentTargetDistance result = GetFocusLensSubjectDistance result!

hi guys!

I have solved the problem of the SD card (1GB kingston). I formated it with 64kb as allocated unit size and it works (I hope it would helps to anybody). Also I have a question... Is there any script for have a screenshot of the camara's screen?

ahaha...good work!

i thought that boot problem was another bug!  :haha

it's enough read FAQ:

Quote
Note2: 4 GB cards can support the autoload feature if they are formated in FAT16 manually. To format SD-card in Windows command line just type 'format X: /fs:fat' (where X: - a drive letter of mounted SD-card). But be aware that the formatting of 4 GB cards in FAT16 leads to non-standard 64K cluster size. The correct support of such cluster size is not guaranteed.

thank hucht!

for the LCD screenshot...i don't know, i'm sorry!

why have you need this features?!
