This page seems to be concerned with a special way of dumping your firmware. For an overview of the ways to dump firmwares see Porting_the_CHDK#Q._How_can_I_get_a_firmware_dump.3F This page describes how to dump the firmware with the help of the serial IR sensor. I hope it contains useful informations for those, who has already built their serial IR sensor device but received nothing via serial port or only corrupted piece of the firmware. The solution could be: set the correct DEL value in the main.c file. Well, this page is still under edit. --Titan_G9 15:57, 19 January 2008 (UTC)
