Hello ppl!
I think it's time to put sd1100 into the trunk. I just merged the latest stuff and made another release:
SD1100/ixus 80 porting .... A patch is attached there. I hope, this build is as stable as the previous. There was no crash report since then.
However, it's still missing the move_rec and sdhc_largedisk support. I hacked that but it still freezes in PLAY mode. It is in the patch but disabled in the build chain.
The greatest problem is, that the diskboot.bin file must be encoded to be bootable. So no hacker can contribute unless running qemu/gdb ... and it can't go to the automated build thing, too.
(Reminder to that prob:
Problems dumping the SD1100IS/IXUS80IS |
Emulating Digicam with QEMU ... udumper2008)
So I wrote this little tool (included in patch):
/*
* make an image bootable for latest cams
* (c) 2008 chr
*
* GPL v3+
*
* Why make things easy if complex sells better?
*/

Note: it's already reverted. Must not run 15 times
TODO: include this somehow into the build chain.
