All the things in the stubs_min.S are addresses.

Hey! I got keyboard works!

Now i can walk in the CHDK menu. 😀

neszt

Now, the SD_READONLY flag is ok, and i can take pictures.

The CHDK menu flickers, and sometimes it's not coming up, and sometimes it is not centered vertically.

Excellent.

It is normal for the menu to get overwritten when the canon screen updates. Pressing up or down should make most of it redraw.

RaduP

Does the menu change the position sometimes?

Thanks. 😀 Is it normal, when i press the menu button both the chdk and the canon menu comes up?

Yes, vertically it is sometimes centered, somtimes at lower position. I need to see a normal chdk now, i look forward youtube videos..

RaduP

No need to forward me the videos, I know what the problem is, I had it too.
Your bitmap buffer length is too small, there are actually two buffers. So you need to make the buffer length bigger. vid_get_bitmap_buffer_height should return more than it does. In my case, it is 30 more.

Regarding your canon and chdk menus coming up at the same time, check your keysmask.

Well, well, both the flickering and the keymasks fixed.

Thanx for patient, and lots of help!

I was wondering, does your screen update properly with the chdk menu on? For example, if you go from a big menu into a small menu, is the big menu still showing partially?

Most of the time the big menu still showing partially. When i enter to a sub-menu, with few items in it, the main menu remaining part still visible. However, as i told before, i never used CHDK, so i don't know, if this is the intended work. Sometimes, the big menu disappears, and only the small menu visible.

What Reyalp says, is annoying that the menu is overwritten when the canon screen updates. It disappears after 5-7 seconds when not moving. Moving up or down it appears quickly.

RaduP

Just as I thought.

It worked for me also! However, now the big menu is not showing when i enter to a small menu, but the canon screen update is more often.. I must push cursor buttons to see the menu after pressing the set (to back from submenu)

RaduP

Yes, that's the normal behaviour I think. But it's better than having the CHDK menu displayed when inactive, even in shoot mode..

I have problems with ARM assembly.

Error: bad expression -- `adreq R0,=0xFF86E8C0'

Original dissasembly:

ADREQ R0, aMounter_c ; "Mounter.c"

RaduP

Replace with ldreq
Both adr and ldr are macros, not real instructions. They do more or less the same thing, but differently.

Ok, thx. I downloaded your vip source again, but i see your sub boot.c is very old, this mounter function is still the original sx10. If you update, you can save a lots of questions. 😀

When using IDA, you should disable generating macros...

[tt]options -> general -> analysis -> processor specific analysis options[/tt] > uncheck 'enable macros'.

Sure, here is an updated version, I also modified the propset2.h , you might find it useful (assuming your camera uses the same props as mine).
