G9 and 16GB SDHC dual partition boot problem

Hi,

anybody working with a G9 and the dual partition boot option? On my Camera (FW version H) I'm able to manually load CHDK from a FAT32 16GB SDHC card and from a FAT16 4GB card even the automatic loading works. However, if I partition the 16GB card as advised (sdb1 16M, sdb2 ~16G), CHDK loads on camera startup but it seems not to switch to the big (2nd primary) partition. The message on the display is MEMORY CARD FULL. If I use "Switch partitions" from the CHDK menu is says "there is only one partition".
Any suggetions?

Nothing so far?
Did anybody try two partitions on a G9 recently?
How could I find out whats going wrong?
I tried it on a smaller (4G) card with two FAT16 partitions. Same result. Is there any log or so I could check?

Second partition must be also 'primary' (not 'extended').

It is. (Under Linux sdx2. AFAIK it would be sdx5 or higher if in extended partition)

@wobbegong: some questions:
- Firmware version of your G9?
- time between camera startup (in playback mode) and blue LED blinking?

Firmware GM1.00H

When the camera is switched on in playback mode it takes less than a second for the blue LED to be switched on shortly and off again and then ~2 sec before the blue LED blinks and the CHDK startup screen is visible.

Well, RAW shooting and variable bitrate in video works?
If yes, try test version (attached to this post).
Please also test how other  bug is fixed - in old CHDK version G9 exits from "C" shooting mode, if <alt> mode is active.

the test version did the trick :-)
RAW works, variable bitrate seems to work (I can see the bitrate beeing calculated while shooting. How do I check if the resulting AVI is variable bitrate?)
Camera stays in "C" after <alt>

AND ... switching of partitions works like a charm!!

The Camera FW is still 1.00H. CHDK seem to be made for 1.00I. Do you know of issues from that?

Not sure if that's what you mean, but under Windows you can use codec info tools like http://www.headbands.com/gspot/ or  http://mediainfo.sourceforge.net

CHDK for 1.00H is just copy of CHDK for 1.00I.
