SX110IS - howto start porting

I have been monitoring the development of CHDK for SX110 and am happy that beta code is now available for testing. When I pressed FUNC SET + DISP, I see on my SX110, Firmware Ver. 1.0.0.0 which is not listed as 1.00b for beta in the CHDK Wiki page. Why? How do I get version b so that it is compatible with the beta code?

You have to use ver.req

Quote from Wiki:
In PLAY mode (without ver.req) press FUNCSET and DISP simultaneously:

Firmware Ver. 1.0.0.0

[ OK ]

Fixed capt_seq.c. Really forgot to call shooting_expo_param_override() :o. Shame on me!
Shooting overrides should work now but didn't test this exhaustive.
capt_seq.c (for devs) and diskboot.bin (for others -- it's in the zip) are attached.

Suggest that we release a comprehensive update to the autobuild server after major changes only.

Cheers.

Rear Curtain flash sync = works!
Shutter Override = works!
Aperture Override = works!
ISO override = works!

Great work chdkj!

updated bugs@wiki

yeah it works 😀

nice work!!!

Quick note - setting OSD all sensors display to 'on' crashes the camera.

for real??
somehow it does not work for me... i downloaded the "sx110is-100b-0.9.8-749-full.zip" from the autobildserver... and replaced the files on my SD-Card with these.
and it still does not work..

Yep, all overrides work! Nice. I used the latest build attached to chdkj's post.
Please note that autobuild isn't as up-to-date as the very latest posts in this forum. It only updates if it is updated 😀

getting software to read these CRW files

try activating 'DNG Extension', that should help software identify it as DNG ...

Yeah - I gave that a shot first thing. No dice w/ every program I could find.

Thanks anyway though! I only hope that the "DNG format" option is on someone's shortlist.

the one posted by chdkj is not full, it only contains diskboot.bin.

I downloaded the 9.8 full version posted on the autobuild server, and i am unable to use the overrides.

=update=
I copied the diskboot.bin file posted by chdkj in my sd card. And now my overrides are working.

thanks to all the developers

I just hope sx110 will have optical zoom in videos soon.

overwrite diskboot.bin

for some reason it only works with an auto-boot
if i use the firmware update method, the overrides do not work

anyhow: nice work

Yes, it is.
Yarvieh works really hard to get a proper color matrix for RAW develop process.

Maybe, I did something wrong, but overrides do work even with fw update method. It's the same binary...

Camera crashes if "Battery Temperature" should be displayed in OSD.

Activating "show battery temperature" or "show all" in OSD and switch to
record mode brings the camera to stop (think so).

OSD --> get_battery_temp() --> _GetBatteryTemperature()
GetBatteryTemperature is correctly declared in stubs_entry.S and the
corresponding function in fw dump seems to be "normal" (like in SX10 or
SX110).

If I change get_battery_temp() to avoid _GetBatteryTemperature() and to
return immediately with a constant (return 123) then 123 will be displayed
and everything is fine.

I don't think that Battery Temperature Support is broken in SX110. But who knows.
No clue...

@obihoernchen, regarding to the list of problems and the last version of CHDK for sx110:
- I think problems no. 8+9 are solved. I didn't encounter problems with zoom wheel or shutter button anymore.
- No. 5 (rear curtain flash sync) seems to be solvedhttps://chdk.setepontos.com/d/2838/170
- No. 6 (print-key=<ALT> and auto-iso-shift) seems to be solved. Auto-ISO-shift works for me. Hyst has originally post this error (https://chdk.setepontos.com/d/2838/110.

chdkj

Strange.
Did exchange address of GetBatteryTemperature with the address of GetCCDTemperature and camera keeps alive. That's not really unexpected. Seems that GetBatteryTemperature is broken.

might be 😀
but maybe I am doing something wrong.

as far as i understood: the FW-Update method goes like this:
everything is copied to the card (diskboot + fi2)
UNlock your card. (when you power up the camera it won't load CHDK.)
in play mode: menu -> last option (firmware update).
now chdk is loaded and overrides do not work 🙁

greetings

EDIT: if i LOCK the card, CHDK is loaded automaticly, and the overrides work.

Yarvieh

Both the diskboot and the fi2 contain the same chdk code one is used with the locked mode the other by the firmware upgrade. chdkj posted a new diskboot but not a new fi2 hence the new and fixed code will run with the locked method but when you use the firmware upgrade the old and unfixed version will be loaded.

lucmovel

Just out of curiosity, would some explain to me why anyone would prefer the more involved "firmware upgrade" method instead of booting straight into CHDK? I really can't see the point.

Yarvieh

Especially when developing the locked mode is *really* annoying unless you modify the card reader on the pc. Another good reason for using the firmware method is that you do no want to run chdk all the time.

Inferno

diskboot.bin has a new CHDK and FI2 is an old bin without override support thats why it doesn't work.
