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

Quick factsEdit

  • Firmware versions 1.0.5 and 1.0.8 and 1.1.1 available.
  • Runs VxWorks
  • ARM946E-S
  • 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

Possible extra functionalityEdit

  • Movie mode
  • 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
