WDT

[asetyde]

I need control reboot operation with wdt .. but all information are deleted without a reason ... Any news ?

If i can't use wdt , to reboot my nay 1.0 how can i do ? i've tried

ESP.wdtEnable(WDTO_8S);
and after put a while(1) , but in serial shows wdt rest but board not reboot

espressif removed the wdt access from SDK.
the current SDK only gives access to what thy called a "software wdt" so not very useful.
if you only want to reboot the ESP try ESP.restart();

If you see wdt reset in serial but the board doesn't reboot, it means some of the bootstrapping pins (GPIO0, GPIO2) are not in the correct state. Make sure GPIO0 and GPIO2 are pulled high.

tommorow i ll try , probably gpio0,
software wdt work so bad , more control is appreciated

There are two WDT timers actually: software one, attached to a sorta-high priority timer interrupt, and a hardware one. If software WDT doesn't fire, hardware WDT will. When you see wdt reset line in serial console, it means that hardware WDT has fired.

If you simply need to reboot your module, use ESP.restart() function.

ok , but before with arduino nano , i 've used avr wdt function , you can set 8ms as time , you enable use of wdt hw and every times your loop time elapse 8ms if you not use wdt reset , system reboot , this i need . But if not possible to preserve system from freeze , i will you use Esp.restart

WDT is already enabled by default.

Software WDT will fire in about one second, and if it doesn't (say you are in a recursive loop, or an infinite loop inside an interrupt) then the hardware WDT will fire in about 5 seconds.

We don't have a function to change WDT interval at the moment.

Ahn ok , now i understand ... Because before i 've see in code this key point

[asetyde]

i thought i can put time and reset every times

[asetyde]

please last question , what is wdtFeed ??

[asetyde]

i use ESP.restart(); but system not restart

[asetyde]

System start ... and eprom init / read are my sysoutprint

[asetyde]

normal system , not rebooted is this ( before EEPROM INTIT use Esp.restart(); command)

Please share your sketch source code. Also please mention which version of
the boards manager package you are using.

i've no authorization to do share code , my library manager is
