Deep sleep wakeup

[Kzilla]

Hi all,

I've been having a problem putting my esp wroom-02 to sleep. I have a reset supervisor tied to the reset line and am trying to use system_deep_sleep(0) after calling os_timer_disarms on all of my timer functions.
The problem is that the system stops functioning, but maintains a current draw of 13mA an does a wdt reset after ~3 seconds:

Code: Select all

state: 5 -> 0 (0)
rm 0
del if0
usl

 ets Jan  8 2013,rst cause:4, boot mode:(3,6)

wdt reset

1) What could be the cause of that problem?

also

2) Is there information somewhere explaining the sdk debug messages seen above? I am referring to rm 0, del if0 and usl and the like.

Hi,

Could the document "9B-ESP8266__Sleep__Function Description" help?

Or you can provide your test code, we will help debug it.
