Can SDM and CHDK be on the same SDHC card In-Camera

I am a Newb.

Just received two Canon A570 IS refurbished cameras from Adorama yesterday along with two Sandisk Ultra II 8GB SDHC cards, and a Ricoh CA-1 remote switch.  ($285 total with shipping to CA.  Probably should have just gotten 4GB cards.  But no problem.)

I've only just loaded the right camera with SDM.

Tell me or point to the thread that I was unable to find:

Can I load both SDM and CHDK on the same SDHC card and run either firmware on a single camera?
Or must I have each on a seperate SDHC card and simply swap out the card as needed?

Or by loading SDM, did I also load CHDK with all of its functionality?

Thanks.

there are certainly people who will tell you that sdm has the same functionality as chdk (i dont belong to these), but this really is your task to find out and compare.

you can have multiple "installations" of chdk on one card, yes. for example you can use one version via autoboot, the other one via the "firmware update method". since SDM doesnt offer the "firmware update method"  ::), you would have to autoboot sdm, and use the "firmware update method" with the chdk.
i havent tried switching diskboot.bin on the fly via the chdk filebrowser, maybe this also works, you could also use chdk's autoboot then.
anyways, welcome to the forum.

I use the SDM installer to create a bootable card (no firmware-update method required) and then install  DISKBOOT.BIN.

If I want to test a CHDK build, I simply temporarily rename to DISKBOOT.BIN.OLD  and copy the CHDK DISKBOOT.BIN to the card.

I can then rename that and use the SDM DISKBOOT.BIN.


Be sure to check-out the new bracketing and time-lapse features.

I've decided to keep things simple.

I made a good install of CHDK on one 8GB Sandisk Ultral II SDHC card.  I was unable to make it bootable but that's no big deal.  I just use the Firmware Update feature and it works fine:  just a couple of clicks.

So when I want to shoot with CHDK I'll just install this card.

And when I want to use SDM I'll install my SDM_Left card.

Just out of curiosity -- what's wrong with your SDM_Right card? Why such discrimination against handedness?

Normally you would use two cameras and left/right cards.

You can use SDM with a single camera for stereo images.

There are a couple of features that aid this, the edge overlay and a 'rangefinder' OSD that lets you measure the near and far distances using the telephoto setting and half-press.

It then tells you how far to move the camera to the right.

For hand-held shots, hiker-john's edge-outline is very useful.

Two builds coexisting on the same card is sort of possible, see note 507 of this feature request: http://chdk.kernreaktor.org/mantis/view.php?id=7.

Well, the CFG files are named differently, no need to have separate folders for scripts, maybe a menu option could simply change DISKBOOT.BIN name  for next reboot ?

DISKBOOT.BIN -> DISKBOOT.BIT   (current build)
DISKBOOT.BI  ->  DISKBOOT.BIN  (alternative build on reboot)
DISKBOOT.BIT -> DISKBOOT.BI   

Anyone tried changing filenames, does it work  ?

As I wrote in the bugtracker link above, it doesn't work because DISKBOOT.BIN is hidden during boot. Any switching should be done before that happens (I'm repeating what reyalp said earlier, I don't know that much about the boot process myself).

If it did work, a Lua script renaming things from arbitrary number of slots (DISKBOOT.0,1,2, PSFIR.0,1,2, CCHDKCFG.0,1,2 etc) would be dead easy to write.
