I made two 4MiB mem dumps for the A1000 just as I did with the G7 yesterday.

Edit: Did the same for IXUS 95. Will stop here though as you didn't say yet if it's useful.

Koshy had a little ELPH which wasn't white as snow but everywhere that Koshy went the ELPH was sure to go. (actually an SD, but that detail ruins the rhyme...)

Please do a quick test, replace :
int vid_get_palette_type() { return 4; }
by
int vid_get_palette_type() { return 2; }
Done. A bit more legible.

g7 100i:
Code: [Select]
void *vid_get_bitmap_active_buffer()
{
    return (void*)(*(int*)0x6ae8); //Found @ 0xff966264 - Two refs to "BmpDDev"
}
Compared to a410, the fw routine @ff966264 looks the same as its a410 equivalent.

About the RAM dumps: I expected a buffer flip between the "before menu" / "after menu" states but both cases use the 1st buffer... Perhaps entering the Canon menu triggers it, I can't predict.

I made a few more entering the Canon menu...

It didn't become clear if you have the A410 to compare. So... A410 works fine, screencap attached.

@koshy

You should be able to determine which frame buffer is active by using chdkptp: if the overlay is correct, it's the first buffer. This method is obviously for ports that do not report the current bitmap buffer. In your latest g7 samples, "inside canon menu" has the 1st buffer active, the rest is 2nd (address is @ 0x6ae8).
I don't need more memdumps at the moment.

I have that cam, I was the one who added the support routines, so I assumed I tested it back then ;)

Patch for ixus95_sd1200 v2.
Previous patches did not include void *vid_get_bitmap_active_buffer().

patch for sx100is.
Port was rewritten using code_gen, please do a full test as done for a2100.
Thanks.

Thank you. I couldn't get it to compile after applying the patch to the trunk though.

Code: [Select]
ERR-SX100IS-100C.TXT
gmake.exe[1]: *** No rule to make target `filewrite.c', needed by `stubs_auto.S'.  Stop.
gmake: *** [all-recursive] Error 1

Can you post a built version for me? FW 100C
