Just make sure to have the romlog from the original crash instead of a crash caused by the lua script or watchdog (there must be no crashes inbetween the first crash and writing the romlog).

Maybe it is triggered by some setting(s) in the CHDK configuration. Does anybody remember what settings you changed from the defaults?

all the testing i have been doing is with stock chdk, no changes

969 -no settings transfered from anywhere, always a fresh formats on the card - NO crashes
972 - same as above - but crashes
1001 and above - crashes...

but on a single 4GB fat16 partition - always perfect - no crashes ever on any build.

i've tried a 2mb and 16mb boot partitions - maybe i need a bigger boot partition???

will try getting the romlog thing - will use build 1050 to test and get romlog.

when i use the romlog.lua in the scripts, it froze the camera, then said :16: error your chdk does not support native function calls.

i read the romlog wiki pages and all but it is a little on the complicated side for me.   Sorry

using 1050, start crashes seem to be rare and only happens the first time after taking some photos and then turning the camera off.

It did the same for me. It just froze even after trying a few times it kept freezing...not crashing. But I didn't get that error 16 like you. I just couldn't turn the camera off or press any  button. I am done with this testing for now. I am now restarting the camera like described in an earlier post. Pressing the start button for a little more than 1 second has solved the problem. That's the way I will do it from now on. That problem is real, it's just that it is very hard for the coders (or chdk expert) to duplicate and find a fix for it and I fully understand and respect that.

I have a great admiration for these guys trying to find a fix. If I would know half of what they know, I would be happy about that.

Hi guys. I am the owner of the Canon powershot sx 20 is (ver1.0.2b) I installed your CHDK. I'm not very pleased with them. I could not install badpixel.lua correctly. After 100 attempts, I created badpixel.bin and put the save in DNG but it does not save in DNG! And when the camera is turned on in active mode, I press alt and then below the display is flashes badpixel bin. If I press the shutter it will begin again the process of creating it. Accelerometer does not work correctly when cdnk enabled. Sometimes the camera doesnt  turn on correctly.The are many bugs( It is an alfa version i think not beta and not the final...

Because the script is no longer needed, and will not work properly in the current version of CHDK. badpixel.bin should be created using the raw menu now.

i think this depend on SX20 testers.Does the Sleep(1000) workaround help on SX20 or not.
Do SX 20 Users get too crash on series shoot in RAW ?

Here is a thread and a possible solution

http://chdk.setepontos.com/index.php?topic=6057.0

but best is to find out, wy the Camera crash sometimes with fsionotify when a makedir is call and sometimes not.
this seem more a dryos problem and no chdk problem.but because dryos can not easy fix, there need workaround in chdk add.

the startproblem on SX20 romlog is too a fsionotify
