This works from the CLI:
Code: [Select]
:\utils\chdkptp-r795>chdkptp -c -i
connected: Canon IXUS 185 , max packet size 512
con> list
*1:Canon IXUS 185  b=bus-0 d=\\.\libusb0-0002--0x04a9-0x32d4 v=0x4a9 p=0x32d4 s=C80A08B1BE404D9CA055C3402EBD7843
con> reconnect

Thanks. I think whatever this is, it's unlikely to be a bug in the ixus 185 CHDK port, since connect/disconnect doesn't really involve much CHDK code.

Can you check following:
In Miscellaneous stuff -> Debug parameters
set Debug data display [Params], Propcase/ParamsData page [ 0]
After exiting CHDK menu, you should see the camera name somewhere in the list (Something like Canon IXUS 185). Which number is displayed in front of that row?

edit: It should be 3. Are there any spaces after the camera name?

Noted, still todo.

Can you run the llibtst script after you made a photo with the camera, and upload llibtst.log?

Thank you.
I don't know whether that trailing space has the potential of causing trouble, seems a minor issue to me.

The llibtst issue is bigger: the camera's stat structure has changed and it is causing some (1 word) corruption in the CHDK RAM area stack. This will need to be dealt with.

edit:
The stat struct change seems to be tied to DryOS r59 (checked sx430, sx730, m100), but more verification is needed.

edit2:
Checked almost all r58 cams, all have the old stat struct.
CAM_DRYOS_2_3_R59 is due.

edit3:
For some (to me) unknown reason, gcc allocates extra space for stack vars in our stat() implementation. As a result, the firmware stat function had no chance to corrupt anything.

More testing, only non-PASS shown.
38. ?    Manual Flash Only in Video - not sure how to test
39. N/A  Hotshoe override
42. N/A  Override JPEG Quality
44. TODO? Subject Distance Bracketing -/+ 10m
51. ?    Custom Auto ISO IS factor does not seem to affect auto ISO
More results in a couple of days.

Attached is a new test build.
Changes:
- fix for the stat() issue, llibtst should now work
- enabled jpeg quality override
- enabled subject distance override in AF (that is, without AF lock or MF lock)
- added the missing mode to mode list

So, to re-test:
- llibtst.lua
- is JPEG quality override effective?
- does subject distance override work when selected in CHDK menu
- mftest.lua

IS factor is only effective on cameras with image stabilizer.

Thanks for these. I added the test build's changes to svn.
mftest: the log says passed, the screenshot says failed  :blink:
52: That might be a glitch in CHDK. Try overriding SD to something and then enable the Inf setting.
