Please forgive me if I am missing something obvious, but after a couple of hours of searching online, in this forum, the 300HS manual and in the CHDK download readme file, I can't seem to figure out how to read the current firmware version of my 300 HS or how to enter the firmware update mode, as of the traditional "Set +DISP" commands seem to do anything but display the current time. Could someone please advise how to do this or where I might find the proper instructions?

Thanks.

Here's a couple of things to look at :

"Set+DISP" is used to enter <ALT> mode once you have CHDK loaded successfully - it has nothing to do with firmware update. Firmware update is a menu item in the original Canon menus on your camera. However, it will only appear in those menus if you have a ps.fi2 file in the root of your SD card and if you start the camera in playback mode by pressing the Play switch - not the On/Off switch.

Thanks, but perhaps I should have been more detailed, I did download, extract and place a copy of PS.FI2, vers.req and DISKBOOT.BIN that I extracted from ixus220_elph300_101e.7z in the root of the SD card, but pressing"Set+DISP" only brings up the time screen.

I also downloaded ACID and SDinst (MAC Versions) but not sure how to use it to read the meta data from a jpeg, as the BIN files from ACID and CHDK are grayed-out.

Do I have to have the proper vers.req or PS.FI2 installed in order to read and update the Firmware version, or am I missing something else?

Thanks Again

Update:

I was able to get ACID to run after doing a low-level format, downloading everything ACID a second time, and letting it download and extract the recommended files as shown below. I copied all the files extracted to the root of the SD card, hit the play mode, but "Set+DISP" still only brings up the Blue Time Screen?

Booting with the SD Card Locked did bring up a brief firmware update splash, and I can now access the CHDK parameters. However, I can now record to the SD card with the SD card protect switch in either position and was wondering if that is normal?

Thanks

Yes, that's normal.

"Set+DISP" is just a way to see the version number on some Canon cameras. It doesn't work on ELPH300HS and you don't need it since you can get the version number from a JPG using ACID or similar programs.

Re: ELPH300HS aka IXUS220HS - Porting Thread - How to access CHDK screen?

Thanks, hope this is not a pain, but after the first boot I can't seem to access the CHDK screen again with the card in protected or unprotected setting. I see the CHDK splash screen but 'Set+DISP" still brings up only the blue screen. Is there some other command to enter the Extra parameters screen?

Thanks

Use the red movie recording button to toggle ALT mode.

Hmmmm. I have to laugh at myself a little here

because all the RED record button seems to do is start video recording. I've tried combinations and holding the red record button during boot, but no ALT mode yet. Is there another button you or some mode it has to be in for that to work?

CHDK has to be loaded already for that to work. Either with the SD lock or powering on the camera by holding the play button and then running CHDK through the "Update firmware" menu.
