S100 porting thread

c10ud

Hello, I did the original port but I'm currently very busy..

I don't exclude that in future I could try porting 101b too but in general what waterwingz said stands correct. (and I'd add that once you have a camera ported, another firmware version isn't very difficult).

Hello c10ud, thanks for bringing CHDK to the S100. I just purchased an S100, and to my disappointment, it is firmware 1.01B.

I will gladly help beta test 1.01B, and thanks a million for all your help and effort.

Kind regards,

same issue...waterwingz...wher can we get the "A" version of firmware. I've searched the canon site, but they only post the latest

Basically, you can't. Canon does not typically provide firmware updates unless there is a major bug. And without their update, you can't change your camera's firmware version. Sorry.

worth the try...I'll post results later today

pdw911

sorry...I meant I'll try the version "A" CHDK

S100 "A" does not appear to work with firmware version "B"

The camera actually hangs up with card locked and battery has to be removed to get camera to start with card unlocked

Verified boot sector was in place with HDHacker. Made disk bootable with EOS card and CHDK files were unzipped directly to SD card, not copied

I can confirm the same behavior when attempting to use the "s100-101a CHDK firmware" on my S100 (FW: 1.01b).

101a and 101b are different firmware. grep from German forum found the differences and compiles a running 101b version.

Thanks..I guess there is hope

I am really new at this...the code you posted is what or goes where???

msl

Firmware version 101b was added in changeset 2001.

Thanks goes to grep.

The S100 101b should be available soon as download.

Thanks goes to grep.

I was trying to understand how the Unix "grep" command was useful in porting to another firmware version for the S100. Then I realized that grep is a user nickname on the CHDK-DE forum. 😳

hqasem

You guys Rock! Thank you c10ud, grep msl and everyone who made this possible. CHDK now runs on my S100 Firmware 1.01B.

pdw911

I must be an idiot....I do what with the changeset...I appologize for my ignorance

pdw911

Thanks...I should have checked...the "B" version is posted

Thanks to all

As I understand, I should unzip directly to SD card, correct???

I believe it doesn't really make a difference. Just make sure:

If your SD card is between 4GB and 32GB (inclusive), format it in camera
Make the card bootable (e.g. using EOScard)
Copy "DISKBOOT.BIN" from the CHDK zip file into the SD card's root directory
Lock the SD card (slide the lock switch)
Place the SD card in your S100, keep holding the On button for couple of seconds, and CHDK will start.

pdw911

Thanks...I understood that CHDK might not start with "on" button....that you would have to initialize with movie button first and then 1/2 press shutter button to switch to camera mode..but apparently you have it working with "on" button

I appreciate the input

hqasem

pdw911
that you would have to initialize with movie button first

That doesn't work for me. I can, however, start the camera by holding the "Play" button for 2 seconds.

pdw911
but apparently you have it working with "on" button

That is correct. Just "keep holding" the On button for 2 seconds. With a non-CHDK card, a single click of the On button will start the camera.

pdw911

Thanks to all who developed this..works very well with power on button

Hi

Thanks for the firmware.
I have a 101A.
1. I Formatted my 16Gb memory with the camera.
2. Then used EOSCard to enable the boot
3. Copied the CHDK to the root of the card.
4. Lock the card, and place back the card
5. Turn on the camera

Now, when I press and hold PLAY button, the CHDK does not show up.

Is there any other trick I am not aware of?

Thanks
