I have same issue and git bisect shows that 641c5cd is somehow relevant.

devyte · 2018-06-30T05:38:47Z

@hreintke could you please take a look?

hreintke · 2018-07-02T15:51:14Z

@devyte Could not test extensive but as far as I can see now, the patch from #4873 fixes also this issue.
core_esp8266_wiring_digital.c
if (localArg->interruptInfo) -> if (localArg && localArg->interruptInfo) is applied.

devyte · 2018-07-02T17:13:53Z

@hreintke I already looked at the pr and approved. Thanks for confirming the change is needed!

devyte · 2018-07-03T17:19:47Z

@baoshuai9527 could you please retest with latest git?

rousir · 2018-07-04T06:13:57Z

@devyte thank you for your help，Today, using the latest git，I tested, new problems appeared.
wdt reset
### The code

#include <SoftwareSerial.h>
#define BAUD_RATE 115200

SoftwareSerial swSer(4, 5, false, 256);

void setup() {
  Serial.begin(BAUD_RATE);
  swSer.begin(BAUD_RATE);

  Serial.println("\nSoftware serial test started");
  
  swSer.println("");

}

void loop() {}

@baoshuai9527 I cannot reproduce the wdt error you are getting.
Your sketch runs flawless in my environment.

Is there anything specific in your setup ?
Which version of sofwareserial are you using ?

rousir · 2018-07-04T11:06:57Z

@hreintke I am using this library https://github.com/plerup/espsoftwareserial

d-a-v · 2018-07-04T11:25:32Z

@baoshuai9527
Please enable debug messages (Tools menu) or show us Serial.println(ESP.getFullVersion());

devyte · 2018-07-04T21:29:37Z

@baoshuai9527 my understanding is that building this core pulls a specific version of the espsoftwareserial, and not the latest git available in that repo. The latest is still untested in our environment.

@d-a-v Sorry to have kept you waiting，I add it

@devyte yes，use SDK:2.2.1(cfd48f3)/Core:win-2.4.1/lwIP:1.4.0rc2 version is normal, esp8266 will not restart.
But this version has problems #4497 ,The latest git has repaired it.

shimarin · 2018-07-10T09:05:14Z

#4913
Maybe worth trying this fix.

rousir · 2018-07-17T07:07:23Z

Thanks for your help, the latest git version solves this problem.

devyte · 2018-07-17T13:11:52Z
