ETS Reset problem .

[Raghu G S]

Hi everyone,
In my application, In soft AP mode, when I try to write EPROM of around 200 bytes continuously, the ESP8266 WIFI module gets reset and displays " ETS RST CAUSE 1 " problem, is there any solution to over come this reset problem or any other way to write the data into EPROM?..

Continuously writing to flash? Do you really want to destroy it in days?

Anyway apparently you didn't grasp the model where you share the processor with the SDK code. No it won't work if you never give the processor to the SDK code. Read all of the other questions (+ answers) about this...

we are writing the data to the external eeprom not to the flash . often it works but some times it fails..

Hi,

Do you feed the watchdog from the write loop?

[eriksl]

Feeding the watchdog will only make the resets go away. It will still make the esp8266 stop functioning properly. If you think you need to feed the watchdog, you have very probably not understood what this is all about.

@eriksl can you explain what is actually wathdog guard in wifi contex and what safety we could get from feeding this dog to not bite us and make the sketch halt or reset ,? Is there any way to notice that we about to bit by watchdog in our sketch
thank
