Bad news.

Yesterday my cam got a E18 "Lens error, restart camera" without any reason!

I did not drop the cam nor did I play with DISKBOOT. It simply refused to work. Looking closly I noticed, the Lens is not correct mounted: The outer "Gummidichtung" (english?!) is not well fitting and maybe caused the blocking.

Today it operates as nothing happened, but vers.req show an "E18" with timestamp in the log.

So tomorrow I'm going to return the cam.

When using a diskboot.bin larger than 30.953.664 Bytes the cam(a590) doesnt even power up

First: omg you got the camera firmware to run in qemu? That is front page material, sir.

Tx for the flowers

I'm going to post details on using qemu-arm in an extra thread for ppl not having IDA. Still sorting stuff and copy'n'pasting stuff from bash_history.

That is great news chr!

I've just returned from vacation (that's "holiday" to my friends across the pond

) with my new SD890 (IXUS 970), and though I had a wonderful time, I hope before my next trip I can have CHDK running on it

To that end: once you have a chance to write up how you got the LED-blinker to load, I'll give it a go on my ixus 970 as well.

I've tried the documented dumping methods briefly before leaving on my trip, but ran out of time when the camera wasn't reacting to diskboot.bin the way I had hoped...

Keep us up to date, thanks

This progress is good. I guess you guys have well and truely answered my original post. The idea of using an alternative to IDA is worthwhile as it eliminates the need obtain a non-free/or other version of IDA.
