SX100IS 1.00b workaround.    In summary it seems that some with SX100 firmware 1.00b are having issues and some are not.        I am in the category of those who are experiencing some problems, however, I am able to get everything working with a little workaround.


This is the startup process I have to use:  (When I press the on/off button it takes me to view picture mode instead of take a photograph mode)  I then press the shutter release which takes me to take a picture mode.  Next I have to make sure to switch the rotary selector on top to M full manual mode.  Then I press the view photo button twice, the first time takes me to view the last picture, and the second time returns me to take a photo in full manual mode.  Now the rotary selector on the back functions as it should.

VER.REQ version display process:

I'm getting the same Blue LED of Death when booting. Rotating the dial does nothing though. Any ideas?

EDIT: Ok, I've gotten 100c to work using a 2gig card, so the problem is related to the 4gig.

Hi,

I'm both yesterday SX100IS and i'm trying to install a CHDK onto this camera.

My firmware is 1.00b :( and so far i have no success in applying a CHDK. I try one from http://grandag.nm.ru/hdk/autobuild/download.htm and also from http://mighty-hoernsche.de/chdk/ .

When I started in a play mode there a red message box that says it there a new CHDK, but in menus all options are disabled. If I try to enter Shooting mode there a blue led just blinks...camera  not responding.

Is somewhere I did wrong or 1.00b is just too tricky...  >:(

At least the SX100 1.00C wont boot into record mode - means, the lens stays retracted, and it's either saying "No Image.", or displaying one of the images on the card..

To get into record mode, you need to press the shutter button half. The lens will extend, and you'll be able to take photos as normal.

You say the menus are disabled. This indeed looks like you're accessing the cameras menu when in playback mode..

As i said, go to record mode with a half press of the shutter. The CHDK menu can only be accessed by going into alt mode first. What the alt mode is, and how you access it, is explained - for example - here: CHDK for Dummies - CHDK Wiki

What do you mean by that?

Hi, I am new in CHDK. I have CANON SX100IS Firmware 1.0.0.0 and A710IS Firmware 1.0.0.0.
As far as I have understood, there is no firmware upgrade and I must buy another camera to get CHDK on it.
Can anyone confirm this to me? Or give me idea how to do the upgrade?!

Thanks

Thanks, Hacki. I've read it before but did not create ver.req file and did not have info on Firmware.

After that, I have not made the card bootable, until I used CardTricks.

Now, it is on and let us see how to use it.

Regards

Hi,

while working on CHDK for SX110IS I've additionally found the addresses for
vid_get_viewport_live_fb() for SX100IS 1.00c.
I believe vid_get_viewport_live_fb in platform\sx100is\sub\100c\lib.c could
look like this:

void *vid_get_viewport_live_fb()
{
    void **fb=(void **)0x21E4; //ROM:FFC2A4FC
    unsigned char buff = *((unsigned char*)0x2098); //ROM:FFC2A4AC ,
ROM:FFC2A4C8
    if (buff == 0) buff = 2;  else buff--;
    return fb[buff];
}

Regards!
