Hi Friends
I download latest versions that works correctly with 1.02b
Subsequent compilations have start problem

1 - The problem occurs when the memory has photos.
2 - With empty memory is more difficult to assess the failure
3 - With two bootable partitions 4GB in Fat16 works best "dbasmith"  8)  Phobia at Fat32!   :P   I prefer one large partition

"Firmware 1.02B.tar.gz"

contains :

sx20-102b-0.9.9--000-full.zip
sx20-102b-1.1.0-DE-full_rev_453.zip         Download = http://www.megaupload.com/?d=GYXVZRMQ


Gift, I leave this photo. Almost to lose. The machine would not start  "  :(   "

I have prepared builds for those versions. Please always install the full build and do not enable zebra or edge.

For 1.02B, rev 972, 999, 1004: http://www.megaupload.com/?d=FYRYU6JS
For 1.02D, rev 972, 999, 1004: http://www.megaupload.com/?d=Y194XYXR

No need to try them all, I'd recommend starting with 999, and if it is good, go down, if broken, go up. Thx.

Thank you so much for this. I have installed version 999 about 8 hours ago and my SX20 has NOT crashed once. Usually, it would have crashed at least 3 or 4 times. I will continue for another day with version 999 but my hopes are high. I am working tomorrow but should be able to test it later in the evening and give you another feedback about 999. Then, I will install 972 and see where it goes from there. I will keep in touch with you.

Again, a big thanks for all your effort and I am sure that by the end of the week, you should have a good idea where the version with the "bug" is.

sorry i haven't had a chance to try any of these builds!  have been busy with work.

if i try 999...and it works ok, do i then try 1004 (as that is the next newest build)?

why not enable zebra or edge with these? (just curious)

thanks so much Ultima!!

will try this tonight once the munchkin is in bed :)

As per Ultima recommendation, after you try 999 and if it's running fine,  you should try 972. I have not had a problem today with 999 :)

Oh my bad, I wrote the exact opposite of what I meant. If 999 works, then try 1004, not 972. The point is, assuming that it got broken at one place and it has been wrong since then, if 999 is working, then you'd have to try a newer (=more recent) version and "hope" to find the breakage. Sorry, I mistyped it in my previous post, but I corrected it now.

The thing about zebra and edge is to try to minimize crashes caused by the lack of memory. Theoretically these crashes shouldn't be happening any more, since both zebra and edge have been modified to work with the sx20, but since you might be experimenting with older builds, I thought I'd give this advice just to stay on the safe side and rule out this possibility. Though now that 999 seems to work fine, it shouldn't matter.

Hi ultimA and Thank you!!!
Test for 1.02B, rev 972, 999, 1004
I tried all three compilations and three with the shutdown problem. Was tested with 300 mb of photos in memory
This happens at random. In some cases, the camera starts, shooting photos, I turn off camera and start again ... Lamp sheds light on... and turn off the camera. After three or four attempts camera starts well

Do not know if this can help,... above download versions that I keep. These works well, without shutdown problem.

Greetings NEZtron

unfortunately still have the same problem with v 999...
but seems to happen only when there are pictures stored on the camera

as you recommended, no zebra or edge and no raw being used.

going to try 972...

edit: can confirm that turn on crash only happens when there are pictures stored, whether it be 1 or more...

Well...my Camera just doesn't like using fat32 or somethin....cause 972 does the same thing, even with no pics stored.
all with no customizing of chdk...stock config.

i double checked my firmware version...it is most definitely d...hmmm

(or does a camera use fat32 regularly without chdk?) <- edit: tested and it does....

maybe the sd card?  have ordered new one....will test again when it arrives.

oh well, will stick to using 4GB fat16 partitions till then

Thanks so much to everyone for trying to help solve the problem,
your all great.

Did you try version 1004? Mine work like a charm with 999. And there are about 50 photos on the card at the moment. I will try 1004 later tonight and report.

Do you mean, when you do firmware update, that camera crash on restart, before last image is show and chdk logo is show ?
this problem i have too very selden on IX1000 HS

when do short after, a second firmware update, most times it work.but sometomes not, then, i need choose other image and switch off the camera.

I notice this the first time when i use  

#define CAM_ZEBRA_ASPECT_ADJUST 1
#define CAM_ZEBRA_NOBUF 1

the crash happen always(when i have longer switch off camera), when i hack zebra display mode, so it show also on play.

but strange is, crash happen, before a image of canon Firmware is show and chdk bootpic is show.

when i use zebra normal(that it is only show on shoot)then i get very selden crash.

seem it depend on jpg pic.i see when i use superfine jpg, i get more often crash.
