Porting CHDK[edit | edit source]

  • Porting for the SD850 with fw version 1.00C is done, the sources are available from the CHDK SVN server, binary packages are available from the DL page
  • SD850 porting thread: forum link.
  • On 7th and 9th March 2008, respectively, Fingalo (aka Christer den Mästare) and Microfunguy (aka David the Stereoguru) added the cam to their regular builds. A couple of days later Fingalo very kindly adapted the port to the then current official CHDK sources at tools.assembla.com and added it to the source trunk in revision 322, thus formally ending the porting phase.
