hi,
does somebody found a way to disable CCont wdt??
writing 0x3F in register 0x05 doesn't work :sad:
byE

EDIT:
sorry CCONT not CCOUNT :)

Well actually I never tried. The watchdog is still my useful way of automatically terminating an experiment :-)

But writing 0x3F or 0xFF should disable it. The firmware itself does that too (see OS IDLE task, it does nothing more then loop into sleep mode -- disabling watchdog) . Well I'll to some experimentation when I have time.

for me it doesnt work too.....

0xFF -> ASIC
0x3F -> CCONT

it SHOULD disable both.... but after about 30 secs the phone is
rebooted (not powered down)
so its ASIC problem?

Well, now you've got timer interrupt handling anyway, why not write the watchdog every 25 (or less) second like you're supposed to? :-)

I begin to fear it is not even possible to disable the watchdog by software, only with the watchdog pin in hw.

Well no problem really. Writing timers is easy.

Hi gentleman,

For me you people are like aliens, the way you talk in hex make me surprised,
i love to understand what all you people talk, but i know you all are genious.

Can somebody tell me how to disable the watch dog by hardware, at this moment this will be enough to me, later i wish one day i could be also like you people.

Goodluck to all of you
