Something interesting, both the SX40HS and the SX50HS share the same sensor, but in platform_camera.h I found a different values for CAM_RAW_ROWS.

// SX50HS:
// Sensor size, DNG image size & cropping
#define CAM_RAW_ROWPIX 4176 // Found @0xff1ae73c
#define CAM_RAW_ROWS 3062 // Found @0xff1ae748

// SX40HS:
// Sensor size, DNG image size & cropping
#define CAM_RAW_ROWPIX 4176 // Found @0xff18e050
#define CAM_RAW_ROWS 3060 // Found @0xff18e05c

Hi Dave,
I was sent to this discussion as it relates to Stick... I have used it to load CHDK using my Mac onto a 32GB SD card with no problems. I have a 128GB SDXC card from Lexar Professional, and Stick doesn't see a card available when it is in the drive. I assume that the 128GB isn't supported by Stick. Is there a way to get it set up to process that size of card?

Thanks
Colin.

While on shooting mode I notice that the Canon menu overlaps chdk's menu.
I use the user menu and I don't notice this much there, but yesterday
I went back to the full chdk menu and could not even read
well some on the menu options, especially on the right part of the screen.
I don't remember this happening before, but then again, I've been using the user menu for a while now.

@londonroadhog

apologies Coln - only just seen your post. STICK can deal with 128GB cards if you edit the stick.properties file (with any text editor) and add/amend the line
maxsize=130000
If you make it 128000 it still might not work, some 128Gb cards are actually slightly bigger.

Some users have reported problems with some card readers - I'm investigating.

Can you post an image showing the problem.

Hi Phil, here is the image.
Notice how the flash icon... on the right, makes it hard to read the menu.

Strange - I've not had that problem, and I can't reproduce it.

What mode do you have the camera in, and what are the Canon menu settings?

It's not likely that much can be done about it - other than to avoid the mode/setting that causes the problem.

It looks like the problem occurs when a TV Ev step value of 10 or slower is used.
It might have something to do with the screen's refresh rate when using a slow TV value.
