CHDK loads "slowly"

On my SD950 there is an approximately 5 second delay before CHDK loads (using ixus960+sd950-100d-1.3.0-3437 and with any previous build tried).  I get the delay whether using the bootable disk method or the manual "firm update." On my other PowerShot cameras, CHDK loads without this delay. Is there a trick for making the SD950 load CHDK more quickly?

It looks like the code in boot.c does not call core_spytask_can_start().  This causes the spy task to wait for about five seconds before proceeding.

This will take a change in the core CHDK code.  Not sure why it's not there already,  but if you are willing to test,  I'm sure somebody can produce a patched version and add it to the autobuild if it works.

I'll do it later if nobody else has a moment or better idea first. Patched version attached - SD card lock booting only.

waterwingz, thanks for the fast reply.  However, the patched version is not loading at all.  No Firm Update menu option is available whether the SD card is inserted locked or unlocked.

The build he posted only supports the autoboot method. You will have to make your card bootable to test this build.
Don't forget what the H stands for.

Thanks! Made the card bootable, and it loaded CHDK immediately! Super! Thanks!
