A little update: the patch above may actually work after all... yesterday while cleaning the MMC card I used for this, I found that there was something in the log from 3 days later.

I had experimented with SSAPI::LcdBrightnessMenuIn. Nothing happened when calling it in PLAY or REC mode, but when in REC mode MENU, camera crashed if it was called twice in a row. It (on a570 100e) sets RAM 0xc614 = 2 (normally 0) when in REC MENU. The crash caused an assert that ended up in the log file.

I ported the Debug log stuff from fudgey and , or at least tried. However I don't get any output to stdout.txt. What sort of output should I be seeing there and when? I do get that one note from platform/main.c console_init() to chdklog.txt, but that's CHDK writing.

The firmware functions in my camera were identical to those in ixus40, memory addresses aside of course.

edit: the changes to trunk 592 attached, I tried to paste them to the message but the forum gives funky errors.

I've added console log code from fudgey & chr to my SD900 port and it worked!

looks like iosInit is the same (ROM:FF811A0C).
Code: [Select]
_iosInit(0x14, 0x32, "/null");
i'm not shure i found correct address of TTY_DRV_NUM yet:
Code: [Select]
int *TTY_DRV_NUM = (int*)0x00011a44;
Camera crashed after i enabled params show in chdk debug menu, result:

stout.txt

I would like to divert /_term to a file.  Where can get the experimental branch you speak of?  I looked in the svn and that experimental branch doesn't have /_term anywhere in it.

Anyone else know?

FYI I diverted /_term to a file in my experimental branch and I also got the console to work... more or less. I couldn't easily put stuff into it so I decided to execute the functions it's got directly instead. It's perfectly possible to do that, even without the shell. It's not extremely useful, though, but it works.

On my A530 toy board (just the mobo, the screen and the i/o stuff with the SD and buttons) there is a missing header, but the connectors are there. There are no labels or anything, which made me think that it could possibly be some debugging/development stuff. One day, when I will have some free time, I'll hook it up to the scope and see if i can 'light' them up by writing stuff in the memory, similar to the LED blinking.
