Hallo,

the camera was broken and so i will built a astrocam with CHDK long expose time.

I have removed the objektiv, also the lense for focus, shutter
I have also removed the flasher .

The Objektive Servo is working without the Objektive so that the Impulses from the Servo is korrekt.
The Focus is also working but without the Lense

So the Camera is also ready to work on my teleskop but one Problem ist difficult .

The POST Routine bring the Objektiv Error E18

When i have a good lock then can i remove a Label from the Led-indikator of Objektiv move, than works.


How i can change the post routine with CHDK or in the original Firmware.

Best Greetings Wolfgang

You need to find where in the original firmware that error is generated. From there, you can hopefully modify CHDK to skip it or ignore the result.

If you aren't good with arm disassembly, this will be a challenge :)

It's possible that someone here has already traced some of that code, but I don't recall seeing any mention of it.
