40Dedit

From CHDK Wiki

Currently, there is no version available for download, it is far from usable yet.

[edit] Quick facts

• Firmware versions 1.0.5 and 1.0.8 and 1.11 available
• Runs VxWorks
• http://www.arm.com/products/CPUs/ARM946E-S.html
• 256MB memory
• Uses AUTOEXEC.BIN instead of DISKBOOT.BIN
  • Needs to be enabled in NVRAM
  • Requires an EOS_DEVELOP disklabel and BOOTDISK 'signature'
  • Can boot from FAT32
  • File format unknown, possibly needs a header but unlikely (probably a plain binary)
  • Runs from 0x800000

[edit] Possible extra functionality

• Movie mode
  • Already somewhat working, see this movie. If it's not clear enough, this one or this one (both are the same) should convince you.
• Live view contrast AF
  • Might already be present in the firmware but that's just a guess based on some strings.
• AF microadjustment
  • Some strings present but functionality likely not implemented.
• Total shot counter
• Scripts
• motion detection
• .....hhhhhhh?
