EOS M3 porting [M3] [EOS_M3]

I'm not familiar with that script, so I can only give a generic answer.
If you shoot right after focus/exposure has settled, the overrides may work. The longer you wait after half pressing, the more likely that the firmware overrides the CHDK override. The issue happens when
- focusing is set to manual
- auto focus doesn't find focus
- "there's no lens", meaning any manual lens that doesn't communicate with the body

I try to find out, what rawopint is doing on MF.

But, rawopint doesnâ€™t work at all with m3-101a-1.5.0-4781. The exposure did not changes
I got the error in log file

sv 411 != cam 480

I had this problem in the past (Reply #259 ) and I thougt is was fixed in platform_camera.h?
With Antâ€™s version m3-101a-1.5.0-35 rawopint works fine.

Update:
Also the black_level is wrong in m3-101a-1.5.0-4781
m3-101a-1.5.0-4781 => black_level=511
m3-101a-1.5.0-35 => black_level=2047

There was no commits for M3 in main repository this year...

The last real update to the M3 platform in the official CHDK source was on Dec 4. AFAIK, no patches for this port have been submitted since.

Edit:

We only make changes if the person doing the port posts a patch.

Maybe I'll try to generate patches for M3 this weekend.

Here's a patch for I think is simple_movie_status. It should be 1 while recording or finishing video, zero otherwise.

Checked - it works. Can be added to main repository.

Thanks for update. No Errors in rawopint and black level is OK.

The issue happens when
- focusing is set to manual
- auto focus doesn't find focus
- "there's no lens", meaning any manual lens that doesn't communicate with the body

I made just 3 short runs with rawopint (around 3*14 pictures)
1) Fast Mode, Auto Focus
2) Fast Mode, Manual Focus
3) Continuous Mode, Manual Focus
I have the camera held on a bright spot (for two shots). Then I kept the camera in a shadow. The exposure follows as I expected. So, there is no different between Auto and MF.

If you shoot right after focus/exposure has settled, the overrides may work. The longer you wait after half pressing, the more likely that the firmware overrides the CHDK override.

I'm not sure how the timing in the script is. Maybe override takes place shortly before the shoot.

Hi,
Disclaimer: fairly new to this. I was wondering when there would be an "official" CHDK zip file download available in http://chdk.wikia.com/wiki/M3 ?
I see there are already some available in this porting thread but was just curious when it would become available within M3's CHDK section.
Two years ago I used an SD880 IS running an intervalometer script for aerial photography on a high altitude balloon. Here are some shots from that flight at 115,000 feet: https://m.imgur.com/a/FxoIM
In about two months I'll be launching another high altitude balloon for a STEM program I'm coordinating for a local children's science museum. This time I've upgraded to an M3 after reading that it can run CHDK.
I'm good at following directions with videos and how to articles, but the how-to on the M3 is littered throughout this thread leaving me a little confused.
This weekend I'll be checking my firmware version and proceeding from there. Can someone guide me to the latest CHDK download that successfully runs on the M3?
Is the latest one under reply #230 of this thread?
Any help is greatly appreciated?

Ant

aparis1983Is the latest one under reply #230 of this thread?

Yes. Link to the latest build always can be found in the first post.

So, I was able to "downgrade my firmware" to 1.0.1 however, when I start the camera in playback mode I don't see a "firmware update" option as you would if I were to install CHDK on another camera. Any suggestions?

Ant

Not sure if this is implemented...
If I run rawopint with display completely off (set_lcd_display) the cam crashes. ROM log attached.
The backlight off (set_backlight) setting works on my M3.

This was not tested before. Will be fixed later...

I've been having some stability issues running CHDK on my m3. It doesn't happen every time I turn on the camera but enough to be frustrating at times. The menus flicker and sometimes the menu will toggle up and down constantly.
Here's a video of the menu:

Try to rotate jogdial and disable electronic level.
