In my firmware 1.00B the "DRYOS version 2.3, release #0023" can be found in the ROM area.
[edit] For Developers
[edit] LED memory addresses
To run the blinker you must have "bootable" SD card with "diskboot.bin"
#define LED_AF 0xc02200C0 // AutoFocus #define LED_BLUE 0xc02200C4 // next to the printer #define LED_RED 0xc02200C8 // next to the play button, rather orange #define LED_GRN 0xc02200CF // in the same position as above, but in green #define LED_PWR 0xc02200D0 // green power on top of the camera
[edit] Dumping the firmware
An almost ready made dumping version (camera, PC), is available you can find here: blinker_sx100.zip
It could be very good to know if all the 1.00B versions are the same and what is the difference among versions.
