I can also confirm diskboot working now. With zebra, the green AF indicator boxes prevent zebra from being drawn below them (zebra stops maybe 20 rows above them), and the draw over modes are not functional.
Low memory mode means zebra won't restore anything.

DNG output still looks funny, the green channel seems to be completely missing

Everything else seems to be working pretty well now. If anyone wants me to test something specific just tell me  :)
Maybe the bayer pattern is wrong. Here's a build with "Red  Green  Green  Blue" instead of  "Green  Blue  Red  Green"

Note that the color matrix appears to copied from sd990, so it the calibration will probably be a bit off.

Thanks, that's much better  8)

After fiddling around a bit with dng4ps2 and the Adobe dng validator, I came up with these additional changes:

Code: [Select]
#define  CAM_COLORMATRIX1                             \
    1484685, 1000000, -530958, 1000000, -208054, 1000000, \
    143142, 1000000, 793552, 1000000, 83907, 1000000, \
    146290, 1000000, -44679, 1000000, 430414, 1000000

#define  CAM_ACTIVE_AREA_X1 8
#define  CAM_ACTIVE_AREA_Y1 12
#define  CAM_ACTIVE_AREA_X2 3692
#define  CAM_ACTIVE_AREA_Y2 2772

The colors are still a bit off compared to the corresponding jpeg, but at least somewhat usable.

Hello,
Nice build, zoom steps are good plus zebra seems much improved- just the ticket.
Beta to Autobuild?

Not sure if this is an issue, but bracketing doesn't work if you set the camera in custom timer mode (worked with this - http://chdk.setepontos.com/index.php/topic,4324.msg52457.html#msg52457 build). Of course, it's not really a problem, since we have scripts, but sometimes it would be just a bit easier to do this with custom timer.

Also, "native" video zoom doesn't work, although works ok with scripts.

Otherwise great work, thanks to everyone who's helping with builds :)

I can confirm this- and doing the equivalent in SDM will run the bracketing sequence properly.

Replying to post this post http://chdk.setepontos.com/index.php/topic,4348.960.html in the sx20 thread, since it really doesn't belong there.

The CHDK folder can be in either partition.
CHDK will only use the folder on the same partition the rest of the camera sees. In a bootable dual partition setup, this means your CHDK folder must be on the large partition. Only diskboot.bin on the small partition is used.
Quote
I used SDMInste to set up my 16Gb so that both partitions are ~8G, so that if I set the switch on the card to 'Lock', I load chdk, and if I unlock it, it doesn't, and there's still enough space on the primary partition for the camera to store images in it when not running chdk.
Are you saying that CHDK successfully autoboots from a FAT32 partition if you have the lock engaged ? If this is true, then you don't need to partition at all. If it isn't true, there's something wrong with your description.

The normal way to have the camera see the large partition without CHDK is to swap them so the large one is first. You can normally swap back by manually loading CHDK, but AFAIK that is not available on sx20 (someone might want to try the my canon basic manual loading method...)
Hello,
I would like to try this as my Ixus 95 does not support using two partitions and the SDM intstaller method, among others, does not work, sadly.
I have already posted that my Ixus 95 will reboot using your Canon Basic method. What I now need help with is how to use it in order to mimic the two partition boot method- one very small fat1n and one large fat32 partition for autoboot plus max use of space.
The ixus95 does not have multipartition support implemented yet. Since diskboot now works, there's no reason to expect that multipartition won't work on this camera when someone gets around to implementing it.

The canon basic method doesn't let you autoboot. It is potentially an alternative to the "firm update" method, but "firm update" already works on ixus95 so it wouldn't be an improvement.
