Intermittent boot poweroff (s90)

Hi all,

My s90 (101c) intermittently fails to boot properly; it will just power off again early in the boot process. I'm not sure if this means chdk has crashed. I spent some time bisecting the svn revision that introduced this behaviour, and it turns out to be r972:

Code: [Select]
------------------------------------------------------------------------
r972 | reyalp | 2010-11-15 09:02:15 +0800 (Mon, 15 Nov 2010) | 1 line

remove spurious "conf_change_script_file" from text reader conf code. thx emlyn and ultimA
------------------------------------------------------------------------

Which looks trivial:

Code: [Select]
Index: core/conf.c

     CONF_INFO( 41, conf.show_clock,             CONF_DEF_VALUE, i:2, NULL),

Reverting this commit makes the camera work as per normal. Since nobody else has a problem with this, could it be a problem with my flashcard files? It may be that I don't have a readme.txt in the proper location.

The use of conf_change_script_file seems incorrect (and the commit correct), but could it be that thing don't work well if script_load (called by conf_change_script_file) is called much later in the conf handling process (entry 38 vs 194)?

Cheers,

This seems possibly related to the troubles with sx20 http://chdk.setepontos.com/index.php?topic=4348.1080

Very strange if this is in fact the cause.

Power off in boot process does mean a crash. Getting a romlog (as described in the linked thread) might shed some light on this.

After compiling in native calls I tried to run romlog.lua, but that fails (so does tstcallf.lua). I have no idea if this functionality is supported in the first place on an s90.

If you have any other hints, I'd be happy to help debug this.

Ah, sorry, I used an old version of the script. With the current one I get a romlog:

I can now confirm that a Sleep(1000) help on Ixus 1000 HS.I get since maybe more than 100 chdk start in last days with that code and super fine pictures no boot crash.

read here for more.

http://chdk.setepontos.com/index.php?topic=4348.msg60115#msg60115

maybe tha additional config read, show only a timing problem that now occur and the notify that tell chdk to continue boot sit on wrong place in newer firmware

and it help to add a sleep
maybe 100 is too ok.

Hi Bernd,

Interesting, I put r972 back and incremented the 400 in main.c to 500 (instead of adding a new msleep), and now the problem is gone as well. I don't know if there's a way to log how many 'i' increments it actually took to initialize things..

Code: [Select]
#ifdef CAM_CHDK_PTP
    init_chdk_ptp_task();
#endif

    while((i++<500) && !spytask_can_start) msleep(10);

    started();
    msleep(50);
    finished();

Hello everyone...I hope that this can help to fix the boot time crash with the sx20 as well that several of us have!

i wish i knew even a quarter of the programming stuff you guys know :)

ah....Reyalp mentioned the sx20 thread above  hehe...hes fast....lol (i must be slow,i missed it the first time i read through)

change the 400 to 500 does not help, its only the maximum time to wait, if the spytask_can_start variable is not set by the port.
then chdk wait 4 sec until start.

you need really add a msleep(1000); after the code.
this mean, when spytask_can_start is set, wait another sec to start.

if you never ever see then a crash you can shorten the value later

"change the 400 to 500 does not help, its only the maximum time to wait, if the spytask_can_start variable is not set by the port. then chdk wait 4 sec until start."

OK thanks. To complicate things, I can't reproduce the problem anymore.. I removed all my hacks, made a clean binary, and everything is fine. Very annoying.. That also means my 400 to 500 change has no relation to the problem, as you mentioned.

The other thing I did was to rsync the CHDK directory to my camera, so that I'd get the latest scritps etc. I wonder if that somehow influences the issue, but there's no way I can roll back to the previous card contents for testing..

the problem depend on what image or video canon firmware want show during start.
a superfine jpg trigger the Problem in 3 of 10 start on my IX1000

I use in the past no superfine, because i see no better image quality.and here i get near 0 crashes, without the added mlseep.so i live with that because i think its IX1000 only.

But when i read about same Problem on SX20, i begin to search, because i know how i can trigger more often.

now i use always superfine and since the sleep is in no crashes come.
