PendingEdit

Ixus220HS/Elph300HS, darkframe control which doesn't seem to work correctly for some reason http://chdk.setepontos.com/index.php?topic=6341.msg82664#msg82664

VxWorks cameras may need CAM_STARTUP_CRASH_FILE_OPEN_FIX too, like the A570IS http://chdk.setepontos.com/index.php?topic=6231.msg87699#msg87699

Cameras that may crash while recording a movie:

Mode switch issue found on some SX series cameras, and a possible remedy: http://chdk.setepontos.com/index.php?topic=5691.msg91269#msg91269

Obscure issue with scripted keypresses in the Canon menu on Digic 4 and higher (only reported on the S90, but probably affects more cameras). Might be related to the functions and fw variables used in vid_bitmap_refresh() implementations. http://chdk.setepontos.com/index.php?topic=8613.msg91483#msg91483

Might be worth it to review subject distance override restrictions on some cameras after changeset 2426, see also changeset 1453

Cameras where AF scan in video is problematic (not full list)

  • Ixus30/SD200, Ixus40/SD300: MakeAFScan() not found
  • A410 (@all res.)
reason (when 640x480 recording):
UsageError!! WBInteg.c WB&AE:SUPER_WIDE -> AE:WIDE_DRAFT
ASSERT!! WBInteg.c Line 869


Ixus95/SD1200, partition support may not work: http://forum.chdk-treff.de/viewtopic.php?f=1&t=3042

S90, looks like the ISO override fix in capt_seq.c is working, perhaps it should be added to the official source. http://chdk.setepontos.com/index.php?topic=8801.msg97159#msg97159

Various cameras have issues with open() or fopen() calls during video recording: http://chdk.setepontos.com/index.php?topic=9986.0

Edge overlay doesn't work well on cameras where the liveview buffers get overwritten during shooting: http://chdk.setepontos.com/index.php?topic=9535.0

CHDK crashes camera when it's started in "clock mode". All cameras seem to be affected: http://chdk.setepontos.com/index.php?topic=10162.0

SX510, using zebra (and/or histogram) sometimes results in memory corruption which leads to crash. The crash always seems to be connected to malloc(), memory used internally by malloc() is among the corrupted areas. Compiling with a different toolchain doesn't make a difference. http://chdk.setepontos.com/index.php?topic=10984.msg112160#msg112160

Further research or actual implementation needed:

DoneEdit

A460, fast liveview buffer: http://chdk.setepontos.com/index.php?topic=8104.msg85367#msg85367

Possible explanation for the "ISO 100 gets recorded into DNG Exif" issue: http://chdk.setepontos.com/index.php?topic=265.msg92075#msg92075

A470, on/off button as replacement for "disp" in ALT mode: http://chdk.setepontos.com/index.php?topic=3368.msg80636#msg80636

How to make CHDK's PTP implementation work on the first DIGIC II cameras http://chdk.setepontos.com/index.php?topic=8600.msg90081#msg90081

Possible workaround for the potential (data) cache vs. modules issue on the S1IS: http://chdk.setepontos.com/index.php?topic=2509.msg91751#msg91751 cache control has been found, appears to work (or at least does not cause crashes).

Ixus105/SD1300, loading CHDK makes USB communication impossible (at least on 1.00d): http://chdk.setepontos.com/index.php?topic=9367.0 , there's also a minor source fix pending

Ixus70/SD1000, saving DNG may fail (?) http://chdk.setepontos.com/index.php?topic=9613.0, probably solved by this commit, see http://chdk.setepontos.com/index.php?topic=10257.msg102210#msg102210

A590IS, to not crash trying SD override http://chdk.setepontos.com/index.php?topic=8263.msg88770#msg88770

SX230HS, crashes while recording a movie when CHDK OSD is visible 101c 100c, weird tearing [1] Appears to be solved by https://trac.assembla.com/chdk/changeset/3111/

A4000, JPEGs tend to get corrupted when using the 'default' EXMEM configuration (aka. autobuild versions): http://chdk.setepontos.com/index.php?topic=9443.msg102326#msg102326 and before... . According to rkomar's report, there's plenty of free RAM without using EXMEM. Hopefully solved by https://trac.assembla.com/chdk/changeset/3185/ and https://trac.assembla.com/chdk/changeset/3186/
