I was exploring some bmp vram stuff in the firmware when I came across the vram structure for the bmp vram.

I printed part of the structure with bmp_printf, you can see it here:


0xF39C is the pointer to the structure. I know this is a vram structure, because off_0x0 (FFA2520C) is a spot in rom which says "Vram Instance".

Also, if you remember that my previous finding for the vram buffer location was 0x589242, the pointer here is very close to this spot. It appears that the vram buffer starts at 0x589200, if you notice the data that says "22442244 22442244" etc, this looks a lot like bmp color information. But, if I set the bmp buffer to be located at 0x589200 in bmp.h, then the text offset is wrong on the screen (the X offset).

Odd.. Also Alex pointed out that I may be printing the fonts as twice their size since 8 bits is one pixel in modern dryos dslrs (where the color palette is 8-bit), but 8 bits is 2 pixels in the 5dc (since there are only 4 bits of colors).

I'm excited to see what this camera can do :) Here's a (not so organized) list of things I've discovered recently:
- setting ISO property above ISO3200 does not seem to have any effect, so ISO caps out a 3200.
- inbetween ISO values like iso2500 don't seem to work, it just sets it to ISO3200.
- the properties seem to work the same as in magic lantern dryos cameras, I used the values for the ISO property from lens.h of magic lantern to test the ISO stuff.
- I discovered that the maximum size for an autoexec.bin seems to be about 2mb, anything higher causes the camera to crash in play mode. This means 5dplus has plenty of room to grow for the future.
Do you know is it possible to get the shuttle count?
