CHDK with Canon Powershoot SX20 IS

Hello,
As a French citizen, I apologize for the inconvenience that may cause my language.
So now, as a student in high school, I have the obligation to make this year a subject of study, and to do that, I need the ability to use CHDK on my digital camera. This is a Canon PowerShoot SX20. So I perform all the tasks necessary to install CHDK. However, I am facing a problem. Indeed, there is not in the version of my device (1.0.2b) the PS.FI2 or PS.FIR files. I am writing to how I could proceed. I also ask you if will not be possible to have these files. Thank you for reading, and I hope a quick and positive response.

Goodbye.

Hi Leo.

Just use this programme to prepare your card for CHDK :-

http://zenoshrdlu.com/stick/stick.html

On completion, LOCK the card and boot your camera.

Looking here : http://chdk.wikia.com/wiki/SX20 you will see that the SX20 does not support the "firmware update" method of booting CHDK, which is why you do not have a PS.FI2 or PS.FIR file

Microfunguy's advice about using STICK is your best alternative. Other information about loading CHDK can be found here : http://chdk.wikia.com/wiki/Prepare_your_SD_card

Salut, je suis désolé pour mon français, mais je suis italien.
J'ai une SX20 IS (1.0.2b), j'ai installé CHDK hier. Vous devez télécharger ce fichier http://zenoshrdlu.com/stick/stick.html, je vous recommande de travailler avec windows xp/7 (j'ai essayé avec ubuntu 9.14 et osx 10.8.2 et 10.9.2 de 2GB 4GB 8GB et 16GB carte SD, mais il ne fonctionne pas), mais avec windows tout fonctionne parfaitement.

Suivez vois ces étapes simples, quand tu à terminè vous bloquez la carte et insérez dans la caméra.

From https://trac.assembla.com/chdk/browser/trunk/platform/sx20/notes.txt:

Code: [Select]

// the SX20 has a very small amount of free ram once CHDK is loaded - probably due to the large display buffers in use^M
// The RAM is so low that edge detection and zebra crash the device^M
// unloading the games from this build free's 14k of ram allowing zebra and edge to^M
// work normally and the random crashes to go away

If you are willing to test, I can send you a version to test CHDK loaded in ARAM.
